Ivosidenib in Chinese patients with relapsed or refractory isocitrate dehydrogenase 1 mutated acute myeloid leukemia: a registry study. BLOOD SCIENCE 2024; 6:e00196. [PMID: 38911469 PMCID: PMC11191922 DOI: 10.1097/bs9.0000000000000196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 05/10/2024] [Indexed: 06/25/2024] Open
Abstract
Ivosidenib, an isocitrate dehydrogenase 1 (IDH1) inhibitor, has demonstrated clinical benefits in a pivotal study (AG120-C-001) in patients with IDH1-mutated (mIDH1) acute myeloid leukemia (AML). A registry study (CS3010-101: NCT04176393) was conducted to assess the pharmacokinetic (PK) characteristics, safety, and efficacy of ivosidenib in Chinese patients with relapsed or refractory (R/R) mIDH1 AML. Patients received ivosidenib 500 mg once daily for 28-day cycles until disease progression. Ten subjects underwent intensive PK/progressive disease (PD) assessments. All subjects had the clinical response assessed at screening, every 28 days through month 12, and then every 56 days. Between November 12, 2019, and April 2, 2021, 30 patients were enrolled; 26 (86.7%) had de novo AML and 18 (60.0%) were transfusion-dependent at baseline. Following single and repeated doses of ivosidenib, median time to maximum plasma concentration (T max) was 4.0 and 2.0 hours, respectively. The inter-individual variability of pharmacokinetic exposure was moderate to high (coefficient of variation [CV], 25%-53%). No obvious accumulation was observed after repeated doses at cycle 2 day 1. Regarding the clinical response, the CR + CRh rate was 36.7% (95% confidence interval [CI]: 19.9%-56.1%), the median duration of CR + CRh was 19.7 months (95% CI: 2.9 months-not reached [NR]), and median duration of response (DoR) was 14.3 months (95% CI: 6.4 months-NR). Consistent clinical benefits and safety of ivosidenib were consistently observed at the final data cutoff with median follow-up time 26.0 months, as compared with primary data cutoff, and the data from Chinese R/R mIDH1 AML patients were also consistent with results from pivotal study.

Abstract
PURPOSE This study aimed to assess the pharmacokinetics (PK) and pharmacodynamics (PD) of ivosidenib in Chinese patients with relapsed or refractory acute myeloid leukemia (R/R AML) carrying the mIDH1 mutation. METHODS A bridging study (NCT04176393) was conducted involving 29 Chinese patients who received a daily dose of ivosidenib 500 mg in 28-day cycles. Plasma concentrations of ivosidenib and D-2-hydroxyglutarate (2-HG) were measured before and after treatment. Non-compartmental analysis (NCA) was employed to evaluate the PK, and an established population pharmacokinetic (popPK) model developed from non-Chinese patients was externally validated. RESULTS The findings revealed comparable PD effects of ivosidenib in Chinese patients with mIDH1 R/R AML. After adjusting for concomitant drug effects, PK characteristics were similar between Chinese and non-Chinese patients. Furthermore, the popPK model offered additional insights into the possible causes of the apparent ethnic difference in PK exposure. CONCLUSION The study indicates that ivosidenib can be used effectively in Chinese patients, and the observed ethnic differences in PK exposure can be explained by concomitant drug effects. The popPK model contributes to a better understanding and optimization of personalized dosing in Chinese patients with mIDH1 R/R AML.

Abstract
BACKGROUND Overexpression of lysophosphatidylcholine acyltransferase 1 (LPCAT1) has been found in various solid cancers and is associated with disease progression, metastasis, and recurrence. However, the expression pattern of LPCAT1 in acute myeloid leukemia (AML) bone marrow remains unknown. The present study aimed to compare LPCAT1 expression differences in bone marrow samples from AML patients and healthy controls and assess the clinical relevance of LPCAT1 in AML. METHODS AND RESULTS LPCAT1 expression in bone marrow was significantly lower in AML than in healthy controls predicted by public databases. Furthermore, real-time quantitative PCR (RQ-PCR) validated that LPCAT1 expression in bone marrow was significantly down-regulated in AML compared to healthy controls [0.056 (0.000-0.846) vs 0.253 (0.031-1.000)]. The DiseaseMeth version 2.0 and The Cancer Genome Atlas analysis revealed that the LPCAT1 promoter was hypermethylated in AML, and there was a strong negative correlation between LPCAT1 expression and methylation (R = - 0.610, P < 0.001). RQ-PCR revealed that the frequency of LPCAT1 low expression was lower in the FAB-M4/M5 subtype than in the other subtypes (P = 0.018). The ROC curve revealed that LPCAT1 expression could serve as a potential diagnostic marker for differentiating AML from controls with an area under the ROC curve of 0.819 (95% CI 0.743-0.894, P < 0.001). In cytogenetically normal AML, patients with LPCAT1 low expression had significantly longer overall survival than those without LPCAT1 low expression (median 19 versus 5.5 months, P = 0.036). CONCLUSIONS LPCAT1 is down-regulated in AML bone marrow, and LPCAT1 down-regulation could be used as a potential biomarker for AML diagnosis and prognosis.

Front Oncol 2022; 12:967657. [PMID: 36518313 PMCID: PMC9742486 DOI: 10.3389/fonc.2022.967657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 10/11/2022] [Indexed: 08/30/2023] Open
Abstract
This is a systematic review and meta-analysis evaluating the prognostic significance of epigenetic mutations on the overall survival (OS) in Acute Myeloid Leukemia (AML). We searched for studies evaluating epigenetic mutations in AML (up to November 2018) in PubMed, Trip database and Cochrane library. Hazard ratio (HR) of outcomes were extracted, and random-effects model was used to pool the results. A total of 10,002 citations were retrieved from the search strategy; 42 articles were identified for the meta-analysis (ASXL1 = 7, TET2 = 8, DNMT3A = 12, IDH =15), with fair to good-quality studies. The pooled HR was 1.88 (95% CI: 1.49-2.36) for ASXL1 mutation, 1.39 (95% CI: 1.18-1.63) for TET2 mutation, 1.35 (95% CI 1.16-1.56) for DNMT3a and 1.54 (95% CI: 1.15-2.06) for IDH mutation. However, there was a substantial heterogeneity in the DNMT3a and IDH studies. In conclusion epigenetic mutations in ASXL1, TET2, DNMT3a and IDH adversely impact OS in patients with AML albeit with considerable heterogeneity and possibly publication bias. Further studies are required to address these limitations.

Abstract
As the risk of harmful environmental exposure is increasing, it is important to find suitable targets for the diagnosis and treatment of the diseases caused. Isocitrate dehydrogenase 2 (IDH2) is an enzyme located in the mitochondria; it plays an important role in numerous cell processes, including maintaining redox homeostasis, participating in the tricarboxylic acid cycle and indirectly taking part in the transmission of the oxidative respiratory chain. IDH2 mutations promote progression in acute myeloid leukemia, glioma and other diseases. The present review mainly summarizes the role and mechanism of IDH2 with regard to the biological effects, such as the mitophagy and apoptosis of animal or human cells, caused by environmental pollution such as radiation, heavy metals and other environmental exposure factors. The possible mechanisms of these biological effects are described in terms of IDH2 expression, reduced nicotine adenine dinucleotide phosphate content and reactive oxygen species level, among other variables. The impact of environmental pollution on human health is increasingly attracting attention. IDH2 may therefore become useful as a potential diagnostic and therapeutic target for environmental exposure-induced diseases.

Reduced expression of lncRNA DLEU7-AS1 is a novel favorable prognostic factor in acute myeloid leukemia. Biosci Rep 2022; 42:231264. [PMID: 35506368 PMCID: PMC9118369 DOI: 10.1042/bsr20212078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Revised: 04/12/2022] [Accepted: 05/03/2022] [Indexed: 11/26/2022] Open
Abstract
The objective of our study was to measure DLEU7-AS1 expression in de novo acute myeloid leukemia (AML) whilst also analyzing its clinical relevance. We used gene expression data from The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), Cancer Cell Line Encyclopedia (CCLE) and Genotype-Tissue Expression project (GTEx) to assess the expression profile of DLEU7-AS1 in pan-cancers, cancer cell lines and normal tissues. Reverse transcription-quantitative PCR was used to measure DLEU7-AS1 expression in bone marrow from 30 normal individuals and 110 patients with de novo AML. DLEU7-AS1 expression was found to be markedly reduced in the AML samples of the TCGA pan-cancer datasets. In our PCR validation, DLEU7-AS1 expression was significantly decreased in the AML samples compared with that in controls (P<0.001). Low DLEU7-AS1 expression (DLEU7-AS1low) correlated positively with lower blood platelet counts (P=0.029). In addition, low DLEU7-AS1 expression was more frequently observed in the intermediate (58%; 44/76) and favorable karyotypes (65%; 15/23) compared with that in the poor karyotype (10%; 1/10; P=0.005). In particular, patients with high expression levels of DLEU7-AS1 (DLEU7-AS1high) showed lower complete remission rates (P=0.002) than patients with DLEU7-AS1low. Survival analysis revealed that patients with DLEU7-AS1low had longer overall survival (OS) than patients with DLEU7-AS1high (P<0.05). Multivariate Cox analysis demonstrated that in patients with non-acute promyelocytic leukemia (non-M3) who were ≤60 years old, DLEU7-AS1 expression was an independent prognostic factor for OS. Furthermore, we found distinct correlations among the expression of DLEU7-AS1, infiltration by immune cells and immune checkpoint genes in AML.

Abstract
INTRODUCTION LINC00324 was overexpressed and facilitated carcinogenesis in various solid malignant tumors. However, the role of LINC00324 in leukemogenesis remains to be elucidated. METHODS The relative expression and unmethylation levels of LINC00324 were detected by real-time quantitative PCR (RT-qPCR) and real-time quantitative methylation-specific PCR (RT-qMSP). Cell proliferation experimental and flow cytometer (FCM) was used to detect the change of proliferation and apoptosis in leukemia cell lines after overexpression of LINC00324. RESULTS The results showed that the expression of LINC00324 and the methylation level of the promoter region were significantly negatively correlated in AML patients. Moreover, patients with lower LINC00324 expression showed more prolonged overall survival (OS). Remarkably, overexpression of LINC00324 in leukemia cell lines promoted the proliferation of target cells and inhibited their apoptosis. CONCLUSION Our findings firstly identified that the hypomethylation of LINC00324 was a common molecular event in de novo AML patients. The abnormally upregulated LINC00324 promotes proliferation and inhibits apoptosis in leukemia cells.

The Role of Epigenetic Modifications in Human Cancers and the Use of Natural Compounds as Epidrugs: Mechanistic Pathways and Pharmacodynamic Actions. Biomolecules 2022; 12:biom12030367.

Abstract
Cancer is a complex disease resulting from the genetic and epigenetic disruption of normal cells. The mechanistic understanding of the pathways involved in tumor transformation has implicated a priori predominance of epigenetic perturbations and a posteriori genetic instability. In this work, we aimed to explain the mechanistic involvement of epigenetic pathways in the cancer process, as well as the abilities of natural bioactive compounds isolated from medicinal plants (flavonoids, phenolic acids, stilbenes, and ketones) to specifically target the epigenome of tumor cells. The molecular events leading to transformation, angiogenesis, and dissemination are often complex, stochastic, and take turns. On the other hand, the decisive advances in genomics, epigenomics, transcriptomics, and proteomics have allowed, in recent years, for the mechanistic decryption of the molecular pathways of the cancerization process. This could explain the possibility of specifically targeting this or that mechanism leading to cancerization. With the plasticity and flexibility of epigenetic modifications, some studies have started the pharmacological screening of natural substances against different epigenetic pathways (DNA methylation, histone acetylation, histone methylation, and chromatin remodeling) to restore the cellular memory lost during tumor transformation. These substances can inhibit DNMTs, modify chromatin remodeling, and adjust histone modifications in favor of pre-established cell identity by the differentiation program. Epidrugs are molecules that target the epigenome program and can therefore restore cell memory in cancerous diseases. Natural products isolated from medicinal plants such as flavonoids and phenolic acids have shown their ability to exhibit several actions on epigenetic modifiers, such as the inhibition of DNMT, HMT, and HAT. The mechanisms of these substances are specific and pleiotropic and can sometimes be stochastic, and their use as anticancer epidrugs is currently a remarkable avenue in the fight against human cancers.

Cancer Med 2021; 10:5283-5296. [PMID: 34227248 PMCID: PMC8335806 DOI: 10.1002/cam4.4085] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 05/28/2021] [Accepted: 06/03/2021] [Indexed: 12/11/2022] Open
Abstract
It was previously reported that PRR34‐AS1 was overexpressed in some solid tumors. PRR34‐AS1 promoter was shown to have a differential methylation region (DMR), and was hypomethylated in acute myeloid leukemia (AML). Therefore, the present study used real‐time quantitative PCR (RQ‐PCR) to explore the expression characteristics of PRR34‐AS1 in AML. In addition, the correlation between the expression of PRR34‐AS1 and clinical prognosis of AML was determined. The findings of this study indicated that high PRR34‐AS1 expression was bound up with shorter overall survival (OS) in AML patients (p = 0.002). Moreover, patients with high expression of PRR34‐AS1 had significantly lower complete remission (CR) rate compared with those with low expression of PRR34‐AS1 after induction chemotherapy. Furthermore, multivariate analysis confirmed that PRR34‐AS1 expression was an independent factor affecting CR in whole‐AML, non‐APL‐AML, and CN‐AML patients (p = 0.032, 0.039, and 0.036, respectively). Methylation‐specific PCR (MSP) and bisulfite sequencing PCR (BSP) were used to explore the methylation status of PRR34‐AS1. PRR34‐AS1 promoter showed a pattern of hypomethylation in AML patients compared with normal controls (p = 0.122). Notably, of whole‐AML and non‐APL‐AML patients, PRR34‐AS1 hypomethylated patients presented a significantly shorter OS than those with a hypermethylated PRR34‐AS1 (p = 0.010 and 0.037, respectively). Multivariate analysis confirmed that the hypomethylation of PRR34‐AS1 served as an independent prognostic indicator in both whole‐cohort AML and non‐APL‐AML categories (p = 0.057 and 0.018, respectively). In summary, the findings of this study showed that abnormalities in PRR34‐AS1 are associated with poor prognosis in AML. Therefore, monitoring this index may be important in the prognosis of AML and can provide information on effective chemotherapy against the disease.

Jung HA, Jung CW, Jang JH. Mutations in genes affecting DNA methylation enhances responses to decitabine in patients with myelodysplastic syndrome. Korean J Intern Med 2021; 36:413-423. [PMID: 33086776 PMCID: PMC7969079 DOI: 10.3904/kjim.2019.385] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2019] [Accepted: 05/15/2020] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND/AIMS In this study, we tested whether mutations in the methylation pathway genes ten-eleven-translocation 2 (TET2) and DNA methyltransferase gene 3A (DNMT3A) improve the responses of patients with myelodysplastic syndrome (MDS) to decitabine. METHODS We retrospectively sequenced the TET2 and DNMT3A genes from 70 patients diagnosed with de novo MDS between June 2008 and December 2011 and treated with a 5-day regimen of decitabine (290 cycles). We then analyzed treatment outcomes. RESULTS Patients with hematological improvement survived longer than those without hematological improvement (22.9 months vs. 10.9 months, p = 0.006). Among the 70 patients, 12 (17.1%) carried TET2 or DNMT3A mutations. The baseline characteristics of patients with wild type or mutated genes were similar. Patients with mutations in TET2 or DNMT3A had a higher overall response rate than those with the wild type genes (82.3% vs. 46.6%, p = 0.023). Multivariate analysis demonstrated that the TET2 or DMNT3A mutation status was associated with improved treatment responses and better overall survival among patients receiving decitabine. CONCLUSION These results demonstrate that TET2 mutations enhance the treatment response of MDS patients to hypomethylating agents like decitabine.

Cancer Manag Res 2020; 12:11871-11881. [PMID: 33239917 PMCID: PMC7682446 DOI: 10.2147/cmar.s278499] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Accepted: 10/17/2020] [Indexed: 01/08/2023] Open
Abstract
Purpose Our research aimed to investigate the expression level of circ_0002232, which is transcribed from PTEN, and find out the association of circ_0002232/miR-92a-3p/PTEN network in acute myeloid leukemia (AML). Methods Circ_0002232 expression in 115 AML patients and 48 controls was detected by using real-time quantitative PCR. The diagnostic value of circ_0002232 expression was evaluated by receiver operating characteristic curve. Kaplan–Meier curves were used to analyse the impact of circ_0002232 for overall survival. Associated network of circ_0002232 was predicted by using interaction prediction websites. Results Compared with controls, circ_0002232 was notably low-expressed in AML (P<0.001). According to the result of receiver operating characteristic curve, circ_0002232 expression could distinguish AML patients from controls (P<0.001). There were significant differences in patients’ age (P=0.004), FAB classifications (P=0.036), white blood cell count (P=0.041) and platelet count (P=0.021) between low-expressed circ_0002232 group and high-expressed circ_0002232 group. Moreover, there was a positive correlation between circ_0002232 expression and patients’ age (Pearson r=0.256, P=0.0057). Interestingly, we found that patients in low-expressed circ_0002232 group had better overall survival both in whole AML (P=0.030) and non-APL AML (P=0.014). Remarkably, the expression of circ_0002232 was positively correlated with PTEN (Spearman r=0.678, P<0.001). Furthermore, there was a negative correlation in AML between circ_0002232 and miR-92a-3p (Spearman r=−0.301, P=0.016), miR-92a-3p and PTEN (Spearman r=−0.324, P=0.034). Interaction prediction websites revealed that circ_0002232 might affect the expression of PTEN and the process of AML through sponging miR-92a-3p. Conclusion Circ_0002232, one of the circRNAs transcribed from PTEN, was remarkably down-regulated in AML and could act as a promising biomarker for the diagnosis of AML. In addition, there might be a potential association network of circ_0002232/miR-92a-3p/PTEN in AML.

(2 R,3 S)-Dihydroxybutanoic Acid Synthesis as a Novel Metabolic Function of Mutant Isocitrate Dehydrogenase 1 and 2 in Acute Myeloid Leukemia. Cancers (Basel) 2020; 12:cancers12102842. [PMID: 33019704 PMCID: PMC7600928 DOI: 10.3390/cancers12102842] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 09/28/2020] [Accepted: 09/30/2020] [Indexed: 12/11/2022] Open
Abstract
Simple Summary Acute myeloid leukemia (AML) is one of several cancers where cancer proliferation occurs under the influence of an aberrant metabolite known as an oncometabolite produced by a mutated enzyme in the cancer cell. In AML, mutant isocitrate dehydrogenases produce the oncometabolite 2-hydroxyglutarate. We screened AML patients with and without mutant isocitrate dehydrogenases by using a technique known as metabolomics, which measures many different metabolites in patient plasma. It was observed that another metabolite, 2,3-dihydroxybutyrate, was produced in larger amounts in patients with mutated isocitrate dehydrogenase and correlated strongly with 2-hydroxyglutarate levels. Moreover, 2,3-dihydroxybutyrate was a better indicator of the presence of mutated isocitrate dehydrogenase in the cancer than the known oncometabolite 2-hydroxyglutarate. These findings may lead to the characterization of 2,3-dihydroxybutyrate as a novel oncometabolite in AML, which would bring a fuller understanding of the etiology of this disease and offer opportunities for the development of novel therapeutic agents. Abstract Acute myeloid leukemia (AML) frequently harbors mutations in isocitrate 1 (IDH1) and 2 (IDH2) genes, leading to the formation of the oncometabolite (2R)-hydroxyglutaric acid (2R-HG) with epigenetic consequences for AML proliferation and differentiation. To investigate if broad metabolic aberrations may result from IDH1 and IDH2 mutations in AML, plasma metabolomics was conducted by gas chromatography–mass spectrometry (GC–MS) on 51 AML patients, 29 IDH1/2 wild-type (WT), 9 with IDH1R132, 12 with IDH2R140 and one with IDH2R172 mutations. Distinct metabolic differences were observed between IDH1/2 WT, IDH1R132 and IDH2R140 patients that comprised 22 plasma metabolites that were mainly amino acids. Only two plasma metabolites were statistically significantly different (p < 0.0001) between both IDH1R132 and WT IDH1/2 and IDH2R140 and WT IDH1/2, specifically (2R)-hydroxyglutaric acid (2R-HG) and the threonine metabolite (2R,3S)-dihydroxybutanoic acid (2,3-DHBA). Moreover, 2R-HG correlated strongly (p < 0.0001) with 2,3-DHBA in plasma. One WT patient was discovered to have a D-2-hydroxyglutarate dehydrogenase (D2HGDH) A426T inactivating mutation but this had little influence on 2R-HG and 2,3-DHBA plasma concentrations. Expression of transporter genes SLC16A1 and SLC16A3 displayed a weak correlation with 2R-HG but not 2,3-DHBA plasma concentrations. Receiver operating characteristic (ROC) analysis demonstrated that 2,3-DHBA was a better biomarker for IDH mutation than 2R-HG (Area under the curve (AUC) 0.861; p < 0.0001; 80% specificity; 87.3% sensitivity). It was concluded that 2,3-DHBA and 2R-HG are both formed by mutant IDH1R132, IDH2R140 and IDH2R172, suggesting a potential role of 2,3-DHBA in AML pathogenesis.

MicroRNA-335/ ID4 dysregulation predicts clinical outcome and facilitates leukemogenesis by activating PI3K/Akt signaling pathway in acute myeloid leukemia. Aging (Albany NY) 2020; 11:3376-3391. [PMID: 31147526 PMCID: PMC6555456 DOI: 10.18632/aging.101991] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Accepted: 05/20/2019] [Indexed: 12/22/2022]
Abstract
MircoRNA-335 (miR-335) has been reported as a significant cancer-associated microRNA, which was often epigenetically silenced and acted as a tumor suppressor gene in diverse human solid tumors. Conversely, recent studies show that miR-335 overexpression was identified in both adult and pediatric acute myeloid leukemia (AML), suggesting that it might play an oncogenic role of miR-335 in AML. However, the role of miR-335 during leukemogenesis remains to be elucidated. MiR-335/ID4 expression was detected by real-time quantitative PCR and/or western blot. Survival analysis was performed to explore the association between miR-335/ID4 expression and the prognosis, and further validated by public databases. Gain-of-function experiments determined by cell proliferation, apoptosis, and differentiation were conducted to investigate the biological functions of miR-335/ID4. Herein, we found that miR-335 expression, independent of its methylation, was significantly increased and negatively correlated with reduced ID4 expression in AML. Moreover, aberrant miR-335/ID4 expression independently affected chemotherapy response and leukemia-free/overall survival in patients with AML. Gain-of-function experiments in vitro showed the oncogenic role of miR-335 by affecting cell apoptosis and proliferation in AML, and could be rescued by ID4 restoration. Mechanistically, we identified and verified that miR-335/ID4 contributed to leukemogenesis through activating PI3K/Akt signaling pathway. Collectively, aberrant miR-335/ID4 expression was an independent prognostic biomarker in AML. MiR-335/ID4 dysregulation facilitated leukemogenesis through the activation of PI3K/Akt signaling pathway.

Abstract
Acute myeloid leukemia (AML) is a highly aggressive hematological malignancy with complex heterogenous genetic and biological nature. Thus, prognostic prediction and targeted therapies might contribute to better chemotherapeutic response. However, the emergence of multidrug resistance (MDR) markedly impedes chemotherapeutic efficacy and dictates poor prognosis. Therefore, prior evaluation of chemoresistance is of great importance in therapeutic decision making and prognosis. In recent years, preclinical studies on chemoresistance have unveiled a compendium of underlying molecular basis, which facilitated the development of targetable small molecules. Furthermore, routing genomic sequencing has identified various genomic aberrations driving cellular response during the course of therapeutic treatment through adaptive mechanisms of drug resistance, some of which serve as prognostic biomarkers in risk stratification. However, the underlying mechanisms of MDR have challenged the certainty of the prognostic significance of some mutations. This review aims to provide a comprehensive understanding of the role of MDR in therapeutic decision making and prognostic prediction in AML. We present an updated genetic landscape of the predominant mechanisms of drug resistance with novel targeted therapies and potential prognostic biomarkers from preclinical and clinical chemoresistance studies in AML. We particularly highlight the unfolded protein response (UPR) that has emerged as a critical regulatory pathway in chemoresistance of AML with promising therapeutic horizon. Futhermore, we outline the most prevalent mutations associated with mechanisms of chemoresistance and delineate the future directions to improve the current prognostic tools. The molecular analysis of chemoresistance integrated with genetic profiling will facilitate decision making towards personalized prognostic prediction and enhanced therapeutic efficacy.

Hypomethylation of MIR-378 5'-flanking region predicts poor survival in young patients with myelodysplastic syndrome. Mol Genet Genomic Med 2019; 8:e1067. [PMID: 31833222 PMCID: PMC6978398 DOI: 10.1002/mgg3.1067] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2019] [Revised: 11/03/2019] [Accepted: 11/05/2019] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Previous studies have disclosed up-regulation of MIR-378 in acute myeloid leukemia (AML), and might consequently affect the outcome of the patients. Correspondingly, hypomethylation of MIR-378 was also identified in AML, particularly for FAB-M2 subtype with t(8;21) chromosomal translocation. Nevertheless, the methylation status of MIR-378 has not been illustrated in myelodysplastic syndrome (MDS). Herein we designed to understand the methylation pattern of MIR-378 involved in MDS and clinical interrelation thereof. METHODS Real-time quantitative methylation-specific PCR (RQ-MSP) was performed to evaluate the methylation degree of MIR-378 5'-flanking region on bone marrow mononuclear cells collected from 95 de novo MDS patients. Five gene mutations (IDH1, IDH2, DNMT3A, U2AF1, and SF3B1) were detected by high-resolution melting analysis to further evaluate the clinical relevance of hypomethylation of MIR-378. RESULTS Unmethylated level of MIR-378 5'-flanking region was significantly higher in MDS patients than that in controls (p = .034). Hypomethylated MIR-378 was identified in 20 of 95 (21%) cases with MDS. Male patients appeared to be more frequent to harbor MIR-378 hypomethylation compared to female patients (15/55, 27.3% vs. 4/40, 10.0%, p = .04). There was no significant difference in age, white blood cell counts, platelet counts, hemoglobin concentration, and karyotypes between the patients with and without MIR-378-hypomethylation. Distinct distribution of five gene mutations was not observed in the two groups as well. However, MIR-378-hypomethylated patients had significantly shorter overall survival than those without MIR-378 hypomethylation (p = .036). Moreover, among patients <60 years, hypomethylation of MIR-378 was confirmed to be an independent adverse prognostic factor by both Kaplan-Meier and Multivariate Cox analyses. CONCLUSION Hypomethylation of MIR-378 5'-flanking region is an adverse prognosticator in MDS, particularly in patients <60 years.

Down-regulation of miR-29c is a prognostic biomarker in acute myeloid leukemia and can reduce the sensitivity of leukemic cells to decitabine. Cancer Cell Int 2019; 19:177. [PMID: 31333331 PMCID: PMC6617691 DOI: 10.1186/s12935-019-0894-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2019] [Accepted: 06/27/2019] [Indexed: 12/13/2022] Open
Abstract
Background MicroRNA-29c (miR-29c) is abnormally expressed in several cancers and serves as an important predictor of tumor prognosis. Herein, we investigate the effects of abnormal miR-29c expression and analyze its clinical significance in acute myeloid leukemia (AML) patients. In addition, decitabine (DAC) has made great progress in the treatment of AML in recent years, but DAC resistance is still common phenomenon and the mechanism of resistance is still unclear. We further analyze the influences of miR-29c to leukemic cells treated with DAC. Methods Real-time quantitative PCR (RQ-PCR) was carried out to detect miR-29c transcript level in 102 de novo AML patients and 25 normal controls. miR-29c/shRNA-29c were respectively transfected into K562 cells and HEL cells. Cell viability after transfection was detected by cell counting Kit-8 assays. Flow cytometry was used to detect apoptosis. Results MiR-29c was significantly down-regulated in AML (P < 0.001). Low miR-29c expression was frequently observed in patients with poor karyotype and high risk (P = 0.006 and 0.013, respectively). Patients with low miR-29c expression had a markedly shorter overall survival (OS) than those with high miR-29c expression (P < 0.001). Multivariate analysis confirmed the independent prognostic value of low miR-29c expression in both the whole cohort as well as the cytogenetically normal AML (CN-AML) subset. Over-expression of miR-29c in K562 treated with DAC inhibited growth, while silencing of miR-29c in HEL promoted growth and inhibited apoptosis. MiR-29c overexpression decreased the half maximal inhibitory concentration (IC50) of DAC in K562, while miR-29c silencing increased the IC50 of DAC in HEL. The demethylation of the miR-29c promoter was associated with its up-regulated expression. Although miR-29c demethylation was also observed in DAC-resistant K562 (K562/DAC), miR-29c expression was down-regulated. MiR-29c transfection also promoted apoptosis and decreased the IC50 of DAC in K562/DAC cells. Conclusions Our results suggest that miR-29c down-regulation may act as an independent prognostic biomarker in AML patients, and miR-29c over-expression can increase the sensitivity of both non-resistant and resistant of leukemic cells to DAC.

Abstract
Background The transcription factor Oct-4 is necessary for maintaining pluripotency and self-renewal of embryonic stem cells, and POU5F1B is a processed pseudogene of Oct-4 with coding capacity. The purpose of this study is to evaluate the expression and clinical implication of POU5F1B in AML. Material/Methods The expression of the POU5F1B transcript was evaluated in 175 newly diagnosed AML patients and 39 healthy controls by use of real-time quantitative PCR (RQ-PCR). Results POU5F1B was underexpressed in AML compared with controls (P<0.001). The receiver operating characteristic (ROC) curve revealed that the POU5F1B transcript level was able to differentiate AML patients from healthy individuals (AUC=0.682). In non-APL AML patients, the POU5F1Blow group had significantly higher WBC than the POU5F1Bhigh group (20.2×109vs. 4.6×109 L−1, P=0.021). Among whole-cohort AML, non-APL AML, and intermediate-risk AML, POU5F1Bhigh patients had obviously higher complete remission (CR) rates than POU5F1Blow patients (P=0.012, P=0.012 and P=0.027). In addition, Kaplan-Meier analysis demonstrated better overall survival (OS, P=0.019, P=0.007 and P=0.046, respectively) in POU5F1Bhigh patients compared with POU5F1Blow patients. Furthermore, in multivariate survival analysis, POU5F1B was independently associated with OS in non-APL AML patients and intermediate-risk AML as a favorable prognostic factor. Conclusions POU5F1B was frequently underexpressed in AML, and might contribute to the diagnosis and prognosis of AML.

[PMID: 30554866 DOI: 10.1016/j.prp.2018.12.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Revised: 11/14/2018] [Accepted: 12/05/2018] [Indexed: 12/11/2022]
Abstract
OBJECTIVE SOX7 downregulation caused by its promoter methylation was associated with poor survival in several types of human solid tumors. However, the pattern of SOX7 methylation and its clinical significance are less studied in hematological malignancies. Herein, we evaluated the methylation pattern of SOX7 in myelodysplastic syndrome (MDS) and determined its clinical implication in patients with MDS. METHODS SOX7 methylation was determined by real-time quantitative methylation-specific PCR (RQ-MSP) in 99 MDS patients. Bisulfite sequencing PCR was applied to confirm the results of RQ-MSP. RESULTS SOX7 methylation was detected in 55.6% of 99 patients but not in healthy donors. No correlation was found between SOX7 methylation and clinical parameters including patient age, gender, white blood cell count, hemoglobin, and platelet count. However, patients with SOX7 methylation harbored more U2AF1 mutation than patients without SOX7 methylation (P = 0.015). Kaplan-Meier curves indicated that the patients with SOX7 methylation presented reduced overall survival (OS) (P = 0.034). Furthermore, subgroup analysis indicated that SOX7 methylation was associated with poor OS in male patients (P = 0.034) and in patients older than 60 years (P = 0.019). According to the multivariate analysis, SOX7 methylation remained as an independent prognosis factor in MDS patients both as dichotomous (HR = 2.14, P = 0.041) and as continuous (HR = 1.55, P = 0.042) variable. Importantly, SOX7 methylation was significantly increased during progression from MDS to secondary acute myeloid leukemia (sAML). CONCLUSIONS Our findings demonstrated that SOX7 methylation conferred adverse prognosis in MDS patients and was associated with leukemia progression.

Abstract
BACKGROUND DNMT3A is a DNA methyltransferase that acts in de novo methylation. Aberrant expression of DNMT3A has been reported in several human diseases, including myelodysplastic syndrome (MDS). However, the pattern of DNMT3A methylation remains unknown in MDS. METHODS The present study was aimed to investigate the methylation status of DNMT3A intragenic differentially methylated region 2 (DMR2) using real-time quantitative methylation-specific PCR and analyze its clinical significance in MDS. RESULTS Aberrant hypomethylation of DNMT3A was found in 57% (51/90) MDS cases. There were no significant differences in age, sex, white blood cell counts, platelet counts, hemoglobin counts and World Health Organization, International Prognostic Scoring System and karyotype classifications between DNMT3A hypomethylated and DNMT3A hypermethylated groups. However, the patients with DNMT3A hypomethylation had shorter overall survival time than those without DNMT3A hypomethylation (11 months vs. 36 months, p=0.033). Multivariate analysis confirmed the independent adverse impact of DNMT3A hypomethylation in MDS. CONCLUSIONS Our data suggest that DNMT3A DMR2 hypomethylation may be a negative prognostic hallmark in MDS.

Abstract
Background and purpose Abundant studies have shown that lncRNA PANDAR plays an oncogenic role in human solid tumors. Although abnormal expression of PANDAR has been well investigated in solid tumors, it was rarely studied in hematologic diseases. Hence, the aim of this study was to determine the PANDAR expression level and its clinical significance in patients with acute myeloid leukemia (AML). Materials and methods For detecting the expression level of PANDAR in 119 AML patients and 26 controls, real-time quantitative PCR was used in this study. The prognostic values were evaluated by using Kaplan-Meier analysis, Cox regression analyses, and logistic regression analysis. Results PANDAR was significantly overexpressed in AML and might be a promising biomarker which could distinguish AML from normal samples (P<0.001). Patients with high expression of PANDAR (PANDAR high) were older and showed higher bone marrow blasts than patients in PANDAR low group (P=0.029 and 0.032, respectively). Significant differences between these groups were also detected regarding risk group and karyotype finding (P=0.009 and 0.041, respectively). Importantly, PANDAR high patients presented a significant lower complete remission rate compared to PANDAR low patients (P<0.001). Furthermore, Kaplan-Meier analysis showed that PANDAR high patients had shorter overall survival compared to PANDAR low patients observing the whole AML cohort, and also in the non-M3 group of patients (P<0.001 and P=0.005, respectively). Multivariate analysis of Cox and logistic regression analysis confirmed that high PANDAR expression was an independent unfavorable risk factor for overall survival and complete remission in both observed patient groups. Conclusion These results revealed that PANDAR was overexpressed in AML, and that higher PANDAR expression was associated with poor clinical outcome. Our study therefore suggests that PANDAR expression is a promising biomarker for prognostic prediction for AML.

Abstract
The current study was aimed to investigate integrin beta-like 1 (ITGBL1) methylation pattern and its clinical relevance in patients with acute myeloid leukemia (AML). Real-time methylation-specific polymerase chain reaction (PCR; RQ-MSP) and bisulfite sequencing PCR (BSP) were performed to detect the methylation of ITGBL1 promoter. Real-time quantitative PCR (RT-qPCR) was performed to analyze ITGBL1 transcript level. The results showed that ITGBL1 methylation level in 131 patients with AML was significantly higher than 29 controls (p < 0.001). The ITGBL1-hypermethylated group tended to have a higher bone marrow (BM) blasts ( p = 0.076). Meanwhile, ITGBL1-hypermethylated patients tended to have a lower complete remission (CR) rate ( p = 0.102). ITGBL1-hypermethylated patients had significantly shorter overall survival (OS) and leukemia-free survival (LFS) than ITGBL1 hypomethylated patients in whole AML cohort ( p = 0.009 and 0.043, respectively) and patients with nonacute promyelocytic leukemia (APL ; p = 0.023 and 0.039, respectively). Multivariate analysis confirmed that the ITGBL1 methylation served as an independent prognostic factor in both patients with whole-cohort AML ( p = 0.030) and patients with non-APL ( p = 0.020). Furthermore, the ITGBL1 methylation level was significantly decreased in follow-up AML patients who achieved complete remission after induction therapy ( P = 0.001). ITGBL1 methylation negatively correlated with ITGBL1 expression in patients with AML ( R = -0.328, p = 0.008). Moreover, demethylation of ITGBL1 could increase the ITGBL1 expression in the K562 leukemic cell line ( p < 0.05). In conclusion, the ITGBL1 hypermethylation is a potential biomarker for predicting prognosis and monitoring disease status in patients with AML.

Abstract
Background Methylation-associated SOX family genes have been proved to be involved in multiple essential processes during carcinogenesis and act as potential biomarkers for cancer diagnosis, staging, prediction of prognosis, and monitoring of response to therapy. Herein, we revealed SOX30 methylation and its clinical implication in acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). Results In the discovery stage, we identified that SOX30 methylation, a frequent event in AML, was negatively associated with SOX30 expression and correlated with overall survival (OS) and leukemia-free survival (LFS) in cytogenetically normal AML among SOX family members from The Cancer Genome Atlas (TCGA) datasets. In the validation stage, we verified that SOX30 methylation level was significantly higher in AML even in MDS-derived AML compared to controls, whereas SOX30 hypermethylation was not a frequent event in MDS. SOX30 methylation was inversely correlated with SOX30 expression in AML patients. Survival analysis showed that SOX30 hypermethylation was negatively associated with complete remission (CR), OS, and LFS in AML, where it only affected LFS in MDS. Notably, among MDS/AML paired patients, SOX30 methylation level was significantly increased in AML stage than in MDS stage. In addition, SOX30 methylation was found to be significantly decreased in AML achieved CR when compared to diagnosis time and markedly increased in relapsed AML when compared to the CR population. Conclusions Our findings revealed that SOX30 methylation was associated with disease progression in MDS and acted as an independent prognostic and predictive biomarker in AML.

J Transl Med 2018; 16:135. [PMID: 29784043 PMCID: PMC5963159 DOI: 10.1186/s12967-018-1494-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2018] [Accepted: 04/21/2018] [Indexed: 12/20/2022] Open
Abstract
Background Increasing studies showed that miR-200 family (miR-200s) clusters are aberrantly expressed in multiple human cancers, and miR-200s clusters function as tumor suppressor genes by affecting cell proliferation, self-renewal, differentiation, division and apoptosis. Herein, we aimed to investigate the expression and clinical implication of miR-200s clusters in acute myeloid leukemia (AML). Methods RT-qPCR was performed to detect expression of miR-200s clusters in 19 healthy donors, 98 newly diagnosed AML patients, and 35 AML patients achieved complete remission (CR). Results Expression of miR-200a/200b/429 cluster but not miR-200c/141 cluster was decreased in newly diagnosed AML patients as compared to healthy donors and AML patients achieved CR. Although no significant differences were observed between miR-200s clusters and most of the features, low expression of miR-200s clusters seems to be associated with higher white blood cells especially for miR-200a/200b. Of the five members of miR-200s clusters, low expression of miR-200b/429/200c was found to be associated with lower CR rate. Logistic regression analysis further revealed that low expression of miR-429 acted as an independent risk factor for CR in AML. Based on Kaplan–Meier analysis, low expression of miR-200b/429/200c was associated with shorter OS, whereas miR-200a/141 had a trend. Moreover, multivariate analysis of Cox regression models confirmed the independently prognostic value of miR-200b expression for OS in AML. Conclusions Expression of miR-200a/200b/429 cluster was frequently down-regulated in AML, and low expression of miR-429 as an independent risk factor for CR, whereas low expression of miR-200b as an independent prognostic biomarker for OS.

Abstract
Although the topography of mutations in persons of predominately European-descent with acute myeloid leukemia (AML) is well-described this is less so in Asians. We studied AML-related mutations in 289 consecutive Chinese (mostly Han) with newly-diagnosed de novo AML. Full-length coding sequence of NPM1 and CEBPA, IDH1 and IDH2 hotspot mutations and WT1 mutations in exons 7 and 9 were analyzed by PCR as were correlations with clinical and laboratory variables. CEBPA mutations were detected in 20% of subjects (95% confidence interval [CI] 15, 25%), NPM1 mutations in 20% (15, 25%), IDH1 mutations in 4% (1, 6%), IDH2 mutations in 11% (7, 15%) and WT1 mutations in 6% (3, 9%). A comparison of these data with mutation frequencies in persons of predominately European-descent with AML indicates a higher frequency of CEBPA mutations, a similar frequency of IDH2 mutations and lower frequencies of NPM1, IDH1 and WT1 mutations. Our data indicate different topographies of AML-associated mutations in Chinese compared with persons of predominately European descent suggesting genetic background, life-style, environment and perhaps other variables may influence these differences.

Abstract
Background The long non-coding RNA H19 plays a crucial role in solid tumor initiation and progression. However, the potential role of H19 and its clinical significance in acute myeloid leukemia (AML) remain largely elusive. Methods H19 expression was detected by qPCR, and clinical significance in AML patients was further analyzed. The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) data for AML were used as validation cohorts. The roles of H19 in cell proliferation and apoptosis were determined by cell proliferation assay and flow cytometry analysis. Results H19 expression was significantly increased in AML patients but not associated with embedded miR-675 expression. Moreover, H19 overexpression was not dependent on the methylation pattern in H19 differentially methylated region/imprinting control region. Strong association was observed between H19 overexpression and patients’ characteristics including sex, higher white blood cells, older age, and intermediate karyotype, FLT3-ITD, and DNMT3A mutations. In addition, H19 overexpression correlated with lower complete remission (CR) rate and shorter overall survival, and further confirmed by multivariate analyses. Importantly, the prognostic effect of H19 expression was validated by TCGA and GEO data. In the follow-up of patients, H19 expression in CR phase was lower than diagnosis time and returned at relapse time. Loss-of-function experiments showed that H19 exhibited anti-proliferative and pro-apoptotic effects in leukemic cell HL60. Furthermore, H19 expression was positively correlated with potential downstream gene ID2 in AML. Conclusions Our findings revealed that methylation-independent H19 was a prognostic and predictive biomarker in AML, and H19/ID2 played crucial roles in leukemogenesis with potential therapeutic target value.

Isocitrate dehydrogenase 2 mutations correlate with leukemic transformation and are predicted by 2-hydroxyglutarate in myelodysplastic syndromes. J Cancer Res Clin Oncol 2018; 144:1037-1047. [PMID: 29549529 DOI: 10.1007/s00432-018-2627-3] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2018] [Accepted: 03/12/2018] [Indexed: 12/01/2022]
Abstract
PURPOSE The myelodysplastic syndromes (MDS) are a group of hematologic disorders characterized by the presence of somatically mutated hematopoietic stem cells (HSCs) that increase the risk of progression to secondary acute myeloid leukemia (sAML). Mutations in isocitrate dehydrogenase (IDHmut) are thought to correlate with the increased production of the oncogenic protein 2-hydroxyglutarate (2-HG) in AML. The aim of this study was to examine whether serum 2-HG has utility as a prognostic biomarker, and whether elevated 2-HG levels are predictive of IDH mutations in patients with MDS. METHODS Genetic profiling was utilized to determine the genetic composition of a large cohort of MDS patients, including the presence or absence of IDH1 or IDH2 mutations (n = 281). Serum 2-HG levels were detected by liquid chromatography-tandem mass spectrometry. RESULTS In the current study of MDS patients, elevated serum 2-HG levels were predictive of inferior overall- and leukemia-free survival irrespective of IPSS risk grouping. Higher serum 2-HG levels predicted the presence of IDH mutations. IDH2mut patients had a higher risk of leukemic transformation. The co-occurrence of DNMT3A or SRSF2 mutations was found to be increased in IDH2mut patients. IDH2 mutations were associated with significantly worse OS and LFS amongst patients with low-risk MDS by IPSS grouping. CONCLUSIONS The noted predictive value of serum 2-HG levels and IDH2 mutations on OS and LFS support the use of biomarkers and/or underlying cytogenetics in novel prognostic scoring systems for MDS.

Zhang ZH, Zhang W, Zhou JD, Zhang TJ, Ma JC, Xu ZJ, Lian XY, Wu DH, Wen XM, Deng ZQ, Lin J, Qian J. Decreased SCIN expression, associated with promoter methylation, is a valuable predictor for prognosis in acute myeloid leukemia. Mol Carcinog 2018; 57:735-744. [PMID: 29457658 DOI: 10.1002/mc.22794] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2017] [Revised: 01/29/2018] [Accepted: 02/12/2018] [Indexed: 12/19/2022]
Abstract
The present study was aimed to investigate SCIN expression as well as promoter methylation and further explore their clinical relevance in acute myeloid leukemia (AML) patients. Real-time quantitative PCR was carried out to detect the expression level of SCIN in 119 AML patients and 37 healthy controls. Real-time quantitative methylation-specific PCR and bisulfite sequencing PCR were carried out to detect SCIN promoter methylation levels in 103 AML patients and 29 controls. As compared with controls, the level of SCIN transcript was significantly down-regulated in AML patients (P = 0.001), and the level of methylated SCIN promoter was significantly higher in AML patients (P = 0.001). Moreover, the level of promoter methylation was weakly negatively correlated with SCIN expression in AML patients (R = -0.265, P = 0.027). Demethylation of SCIN promoter by 5-aza-2'-deoxycytidine could restore its expression in leukemic cell line THP1. The age of SCINlow patients was significantly higher and C/EBPA mutation was significantly less than SCINhigh patients (P = 0.039 and 0.038, respectively). Moreover, the rate of complete remission (CR) of SCINlow patients was significantly lower than SCINhigh patients (P = 0.009). Kaplan-Meier analysis showed that low SCIN expression was associated with shorter overall survival (P = 0.036). Cox regression analysis demonstrated low SCIN expression was an independent poor prognostic factor (P = 0.047). Furthermore, SCIN expression was restored in those patients who achieved CR after induction therapy (P = 0.003). These findings indicate that decreased SCIN expression associated with its promoter methylation is a valuable biomarker for predicting adverse prognosis in AML patients.

Pseudogene BMI1P1 expression as a novel predictor for acute myeloid leukemia development and prognosis. Oncotarget 2018; 7:47376-47386. [PMID: 27329719 PMCID: PMC5216948 DOI: 10.18632/oncotarget.10156] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2016] [Accepted: 06/06/2016] [Indexed: 12/18/2022] Open
Abstract
The BMI1P1 levels of 144 de novo AML patients and 36 healthy donors were detected by real-time quantitative PCR (RQ-PCR). BMI1P1 was significantly down-regulated in AML compared with control (P < 0.001). A receiver operating characteristic (ROC) curve revealed that BMI1P1 expression could differentiate patients with AML from control subjects (AUC = 0.895, 95% CI: 0.835–0.954, P < 0.001). The percentage of blasts in bone marrow (BM) was significantly lower in BMI1P1 high-expressed group versus low-expressed group (P = 0.008). BMI1P1 high-expressed cases had significantly higher complete remission (CR) than BMI1P1 low-expressed cases (P = 0.023). Furthermore, Kaplan–Meier demonstrated that both whole AML cohort and non-M3-AML patients with low BMI1P1 expression showed shorter leukemia free survival (LFS, P = 0.002 and P = 0.01, respectively) and overall survival (OS, P < 0.001 and P = 0.011, respectively) than those with high BMI1P1 expression. Multivariate analysis also showed that BMI1P1 over-expression was an independent favorable prognostic factor for OS in both whole and non-M3 cohort of AML patients (HR = 0.462, 95% CI = 0.243–0.879, P = 0.019 and HR = 0.483, 95% CI = 0.254–0.919, P = 0.027). To further investigate the significance of BMI1P1 expression in the follow-up of AML patients, we monitored the BMI1P1 level in 26 de novo AML patients and found that the BMI1P1 level increased significantly from the initial diagnosis to post-CR (P < 0.001). These results indicated that BMI1P1 might contribute to the diagnosis of AML and the assessment of therapeutic effect.

Low Expression of FUS1 Is Negatively Correlated with miR-378 and May Predict Adverse Prognoses in Acute Myeloid Leukemia. Acta Haematol 2018; 139:89-95. [PMID: 29393096 DOI: 10.1159/000486663] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2017] [Accepted: 12/23/2017] [Indexed: 12/28/2022]
Abstract
FUS1 is a tumor suppressor gene that has been found to be frequently lost in a variety of solid tumors. In this study, we aimed to investigate the expression status of the FUS1 gene in acute myeloid leukemia (AML), as well as its clinical significance. We further explored the correlation between the expression of FUS1 and miR-378 in AML. We detected expression of the FUS1 transcript in bone marrow mononuclear cells from 23 controls and 158 newly diagnosed AML patients by real-time quantitative polymerase chain reaction. Downregulated FUS1 expression was found in 139 out of 158 (87.97%) AML cases; this rate was significantly lower than that in all 23 controls (p = 0.012). Receiver operating characteristic curve analysis revealed that the FUS1 transcript level could discriminate AML patients from controls effectively (area under the ROC curve = 0.663). Kaplan-Meier analysis demonstrated that non-M3-AML patients with a low FUS1 expression had a shorter overall survival (p = 0.049) and leukemia-free survival (p = 0.051) than those with a high FUS1 expression. Furthermore, we studied the correlation between the expression of FUS1 and miR-378 in 53 newly diagnosed AML patients. We found that the correlation coefficient was -0.346, which showed that FUS1 and miR-378 were negatively correlated in AML patients (p = 0.011). These results indicate that the low expression of FUS1 is a common molecular event in AML.

Abstract
Activation of Wnt/β-catenin signaling played a crucial role in tumorigenesis, and β-catenin (CTNNB1) overexpression has been identified in numerous solid tumors. The present study was designed to determine CTNNB1 expression and its clinical significance in Chinese de novo acute myeloid leukemia (AML) patients. Real-time quantitative PCR was carried out to detect the pattern of CTNNB1 expression in 140 AML patients and 46 controls. The level of CTNNB1 transcript in AML patients was significantly up-regulated compared with controls (P < 0.001). CTNNB1high patients showed significantly older age than CTNNB1low patients (P < 0.05). The frequency of high CTNNB1 expression was significantly observed in patients with intermediate/poor karyotypes. CTNNB1high patients had a significantly lower complete remission (CR) rate than CTNNB1low patients (P = 0.004). Among cytogenetically normal AML (CN-AML), CTNNB1high patients presented significantly shorter overall survival (OS, P = 0.004) and leukemia-free survival (LFS, P = 0.038) than CTNNB1low patients. Multivariate analysis confirmed that CTNNB1 expression was an independent prognostic factor for OS among CN-AML. Moreover, CTNNB1 expression level significantly decreased after CR stage (P = 0.032) and increased in relapsed stage (P = 0.015). Our findings suggest that CTNNB1 is overexpressed and confers a poor prognosis in AML, and could be used as a biomarker in monitoring disease recurrence.

Abstract
Chemerin is dysregulation in numerous solid cancers. However, only little is known about the role of chemerin in acute myeloid leukemia (AML). In this study, we aimed to investigate the expression and clinical significance of recently described chemerin in acute myeloid leukemia (AML). The expression of chemerin in 149 patients with de novo AML and 35 normal controls was quantified by Real-time quantitative PCR (RQ-PCR). Chemerin was down-expressed in AML compared with controls (P=0.042). A receiver operating characteristic (ROC) curve revealed that chemerin expression could differentiate patients with AML from control subjects (AUC=0.611, 95% CI: 0.490-0.732; P=0.042) respectively. The cohort of AML patients was divided into two groups according to the cut-off value of 0.0826 (79% sensitivity and 54% specificity, respectively). In addition, the AML patients with low chemerin expression had significantly shorter overall survival (OS) than those with high chemerin expression (P=0.049). Moreover, multivariate survival analysis confirmed that chemerin was an independent prognostic factor for AML patients. In conclusion, downregulation of chemerin might be a useful diagnostic and prognostic factor for AML patients.

Abstract
BACKGROUND Genomic sequencing technologies have identified isocitrate dehydrogenase (IDH) mutations in haematological malignancies. The prognostic implications of somatic IDH mutation (mIDH) in myelodysplastic syndromes (MDS) remain controversial. METHODS Mutations in IDH1 and IDH2 were detected using genomic sequencing technologies in 97 patients with MDS. RESULTS Seven (7.2%) mutations were identified: 3 in IDH1 (all R132C) and 4 in IDH2 (3 R140Q and 1 R140L). The frequency of mutation was 16.6% (2/12) in refractory anaemia with excess blasts (RAEB)-1 and 14.7% (5/34) in RAEB-2. IDH1/2 mutations were closely associated with higher bone marrow blast counts (median 10.0 vs. 2.3%; p = 0.019) and lower absolute neutrophil counts (median 0.44 × 109/L vs. 1.21 × 109/L; p = 0.027). All IDH mutations were mutually exclusive and heterozygous. IDH mutations were not significantly correlated with any specific karyotype. Patients with IDH1 mutations exhibited shorter overall and progression-free survival (OS and PFS; p = 0.039 and p = 0.042, respectively), whereas IDH2 mutations did not affect OS or PFS (p = 0.560 and p = 0.218, respectively). Multivariate analysis indicated that IDH1 mutation (p = 0.018; hazard ratio [HR] 4.735; 95% confidence interval [CI] 1.299-17.264), karyotype risk (p = 0.036; HR 1.619; 95% CI 1.033-2.539) and the revised International Prognostic Scoring System risk category (p < 0.0001; HR 2.122; 95% CI 1.401-3.213) were independent inferior prognostic factors. CONCLUSIONS IDH1 mutation is associated with a poor prognosis.

Abstract
Dysregulation of ID proteins is a frequent event in various human cancers and has a direct role in cancer initiation, maintenance, progression and drug resistance. Our previous study has revealed ID1 expression and its prognostic value in acute myeloid leukemia (AML). Herein, we further reported ID2 expression and its clinical significance in AML. Real-time quantitative PCR was performed to detect ID2 transcript level in bone marrow mononuclear cells of 145 de novo AML patients. ID2 expression was significantly up-regulated in AML patients compared with controls. ID2 overexpression occurred with the highest frequency in poor karyotype (10/17, 59%), lower in intermediate karyotype (35/83, 42%), and the lowest in favorable karyotype (7/40, 18%). Moreover, high ID2 expression correlated with lower complete remission (CR) rate, shorter overall survival, and acted as an independent prognostic biomarker in whole-cohort AML and non-M3-AML patients. Importantly, the prognostic value of ID2 expression in AML was validated by The Cancer Genome Atlas (TCGA) data. In the follow-up of patients, ID2 expression at CR phase was decreased than at the time of diagnosis, and was increased again at the time of relapse. These findings demonstrated that bone marrow ID2 overexpression was a frequent event in AML patients, and predicts poor chemotherapy response and prognosis.

Abstract
The prognostic value of RAS mutations has been systematically investigated in acute myeloid leukemia (AML). However, clinical significance of RAS expressions in AML remains poorly determined. To explore the clinical significance, we analyzed KRAS and NRAS expressions in 143 de novo AML patients by real-time quantitative PCR. KRAS and NRAS expressions were significantly up-regulated in AML patients. KRAS and NRAS mutations were identified in 4% (6/143) and 8% (12/143) of these patients, respectively. However, no significant association was observed between RAS mutations and expressions. High KRAS expression was associated with older age, higher white blood cells, and a tendency of higher platelets, whereas high NRAS expression was only correlated with older age. Complete remission (CR) rate and overall survival of AML patients were adversely affected by KRAS overexpression, but not NRAS overexpression. Multivariate analysis revealed that KRAS acted as an independent prognostic predictor in cytogenetically normal AML (CN-AML). Moreover, the prognostic value of KRAS expression was validated using the published data from Gene Expression Omnibus datasets. In the follow-up patients, KRAS expression rather than NRAS expression in CR time tended to decrease compared to newly diagnosis time, and both KRAS and NRAS expressions were significantly increased when in relapse time. Our findings revealed that RAS overexpression and mutations were common events in AML with potential therapeutic target value. KRAS overexpression independent of RAS mutations conferred an adverse prognosis in CN-AML.

Abstract
Objective Secreted frizzled-related proteins (SFRPs) as Wnt signaling antagonists have been found to be dysregulated by promoter hypermethylation in several cancers including acute myeloid leukemia (AML). This study aimed to investigate the methylated status of SFRPs promoter region and its clinical relevance in Chinese non-M3 AML patients. Methods SFRPs methylation in 139 primary non-M3 AML patients was determined using methylation-specific real-time quantitative polymerase chain reaction. Results The frequency of aberrant methylation was as follows: 30.2% for SFRP1, 27.3% for SFRP2, 5.0% for SFRP4, and 1.4% for SFRP5. Hypermethylation of at least one SFRP gene occurred in 51.8% (72/139) of non-M3 AML patient samples, which was significantly higher compared to normal control (0/21) (P<0.001). Hypermethylation of SFRP1 was potentially associated with N/K-RAS mutations (P=0.043), and the frequency of SFRPs methylation was higher in patients ≥50 years compared to those <50 years, especially for SFRP2 (P<0.05). Furthermore, both whole cohort and cytogenetically normal (CN) patients with high SFRPs-methylated group showed a shorter overall survival (OS) compared to those with low group (P=0.036 and P=0.035, respectively). Moreover, Cox regression multivariate analysis revealed that SFRPs hypermethylation acts as an independent prognostic biomarker among both whole cohort (hazard ratio =1.804, P=0.026) and CN (hazard ratio =2.477, P=0.023) patients. In leukemic cell line HL60 treated with 5-aza-2′-deoxycytidine, the alteration of SFRP1/2 expression inversely correlated with change in SFRP1/2 methylation (r=−0.975, P=0.005 and r=−0.975, P=0.005, respectively). A tendency of negative correlation was observed between SFRP1 expression and its promoter methylation in AML patients (r=−0.334, P=0.038). Conclusion These findings suggested that hypermethylation of SFRP1/2 was a frequent event and silenced SFRP1/2 expression in AML. Moreover, hypermethylation of SFRPs promoter was an adverse risk factor for OS in Chinese non-M3 AML patients.

Abstract
Dysregulation of NKD1 has been identified in several solid tumors. However, the status of NKD1 expression and its clinical implication in acute myeloid leukemia remain largely elusive. NKD1 transcript level in bone marrow mononuclear cells was detected by real-time quantitative polymerase chain reaction in 126 de novo acute myeloid leukemia patients and 30 controls. Clinical significance of NKD1 expression was obtained by the comparison between the patients with low and high NKD1 expression. NKD1 messenger RNA level was significantly decreased in acute myeloid leukemia patients compared with controls ( p = 0.019). There were no significant differences between patients with low and high NKD1 expression in sex, age, peripheral blood cells, bone marrow blasts, French-American-British/World Health Organization subtypes, and karyotypes/karyotypic classifications ( p > 0.05). Although no significant difference was observed in complete remission rate between NKD1low and NKD1high patients ( p > 0.05), Kaplan-Meier analysis revealed that NKD1low patients showed shorter overall survival time than NKD1high patients in whole-cohort acute myeloid leukemia, non-M3 acute myeloid leukemia, and cytogenetically normal acute myeloid leukemia ( p = 0.014, 0.063, and 0.020). Multivariate analyses disclosed the low NKD1 expression was an independent risk factor in cytogenetically normal acute myeloid leukemia patients (hazard ratio = 0.397, p = 0.017). Moreover, the prognostic value of NKD1 expression was confirmed by gene expression profile data in cytogenetically normal acute myeloid leukemia patients ( p = 0.028 and 0.011). NKD1 showed significantly increased level after induction chemotherapy achieved complete remission in follow-up paired acute myeloid leukemia patients ( p < 0.001). These findings indicated that reduced NKD1 expression is associated with unfavorable clinical outcome in cytogenetically normal acute myeloid leukemia.

Abstract
Promoter hypermethylation-mediated inactivation of ID4 plays a crucial role in the development of solid tumours. This study aimed to investigate ID4 methylation and its clinical relevance in myeloid malignancies. ID4 hypermethylation was associated with higher IPSS scores, but was not an independent prognostic biomarker affecting overall survival (OS) in myelodysplastic syndrome (MDS). However, ID4 hypermethylation correlated with shorter OS and leukaemia-free survival (LFS) time and acted as an independent risk factor affecting OS in acute myeloid leukaemia (AML). Moreover, ID4 methylation was significantly decreased in the follow-up paired AML patients who achieved complete remission (CR) after induction therapy. Importantly, ID4 methylation was increased during MDS progression to AML and chronic phase (CP) progression to blast crisis (BC) in chronic myeloid leukaemia (CML). Epigenetic studies showed that ID4 methylation might be one of the mechanisms silencing ID4 expression in myeloid leukaemia. Functional studies in vitro showed that restoration of ID4 expression could inhibit cell proliferation and promote apoptosis in both K562 and HL60 cells. These findings indicate that ID4 acts as a tumour suppressor in myeloid malignancies, and ID4 methylation is a potential biomarker in predicting disease progression and treatment outcome.

Abstract
OBJECTIVES This study was intended to investigate the expression status of Vimentin 2p (VIM 2p), a pseudogene of Vimentin, and further analyze its clinical significance in AML patients. METHODS Real-time quantitative PCR (RQ-PCR) was employed to explore the expression status of VIM 2p in 128 patients with de novo AML and 36 healthy controls. RESULTS The expression level of VIM 2p was significantly decreased compared with healthy controls (P< 0.001). The patients with low VIM 2p expression were identified in 93 of 128 (73%) of AML patients. No significant differences could be observed in sex, age, blood parameters, FAB/WHO subtypes, karyotype risks and ten gene mutations (FLT3-ITD, NPM1, C-KIT, IDH1/IDH2, DNMT3 A, C/EBPA, N/K-RAS and U2AF1) between VIM 2p low-expressed and high-expressed patients (P> 0.05). Patients with low VIM 2p expression had significantly shorter overall survival (OS) than those with high VIM 2p expression in whole AML cases (median 7 vs. 13 months, respectively, P= 0.032), besides cytogenetically normal AML (CN-AML) and non-M3 AML cohort (P= 0.042 and 0.045, respectively). CONCLUSIONS These findings indicate that VIM 2p down-regulation is a common event in AML and may be associated with poor clinical outcome.

Abstract
Purpose: Whether isocitrate dehydrogenase (IDH) gene aberrations affected prognosis of patients with acute myeloid leukemia (AML) was controversial. Here, we conducted a meta-analysis to evaluate their prognostic value.Experimental Design: PubMed, Embase, Cochrane, and Chinese databases were searched to identify studies exploring how IDH gene aberrations affected AML outcome. Pooled HRs and relative risks (RR) were calculated, along with 95% confidence intervals (CI).Results: Thirty-three reports were included. IDH mutations seemed not to affect overall survival (OS: HR, 1.05; 95% CI, 0.89-1.23) and event-free survival (EFS: HR, 0.97; 95% CI, 0.80-1.18) when considered as a single factor, but improved accumulative incidence of relapse (CIR: HR, 1.44; 95% CI, 1.18-1.76) in patients with intermediate-risk karyotypes (IR-AML). However, IDH1 mutation conferred worse OS (HR, 1.17; 95% CI, 1.05-1.31) and EFS (HR, 1.29; 95% CI, 1.07-1.56), especially in patients with normal cytogenetics (OS: HR, 1.21; 95% CI, 1.01-1.46; EFS: HR, 1.56; 95% CI, 1.23-1.98). Prognosis of the IDH1 single-nucleotide polymorphism rs11554137 was also poor (OS: HR, 1.34; 95% CI, 1.03-1.75). IDH2 mutation improved OS (HR, 0.78; 95% CI, 0.66-0.93), particularly in IR-AML patients (OS: HR, 0.65; 95% CI, 0.49-0.86). The IDH2 (R140) mutation was associated with better OS among younger cases (HR, 0.64; 95% CI, 0.49-0.82). Treatment outcome was poor [RR for complete remission rates in IDH1 mutation: 1.21; 95% CI, 1.02-1.44; IDH2 (R172) mutation: 2.14; 95% CI, 1.61-2.85].Conclusions: Various subtypes of IDH mutations might contribute to different prognosis and be allowed to stratify IR-AML further.

Abstract
BACKGROUND Epithelial-mesenchymal transition (EMT) is a critical process which involves in tumor metastasis. As an important EMT marker gene, CDH1 (E-cadherin) expression and its clinical implication in acute myeloid leukemia (AML) remain largely elusive. METHODS Real-time quantitative PCR (RQ-PCR) was carried out to examine CDH1 transcript level in 123 de novo AML patients and 34 controls. RESULTS Compared with controls, CDH1 was significantly downregulated in AML (p<0.001). The median level of CDH1 expression divided total AML patients into CDH1 low-expressed (CDH11ow) and CDH1 high-expressed (CDH1high) groups. There were no significant differences between the two groups in age, peripheral blood cell counts, complete remission (CR) rate, and the distribution of FAB/WHO subtypes as well as karyotypes/karyotypic classifications (p>0.05). However, CDH11ow group tended to have a higher bone marrow (BM) blasts (p=0.093). The spearman correlation analysis further illustrated a trend towards a negative correlation between CDH1 expression level and BM blasts (r=-0.214, p=0.052). CDH1low group had a tendency towards a lower frequency of N/K-RAS mutations (p=0.094). Furthermore, CDH1low patients had markedly shorter overall survival (OS) time in cytogenetic normal AML (CN-AML) (p=0.019). Both univariate and multivariate analyses confirmed the prognostic value of CDH1 expression in CN-AML patients (p=0.027 and 0.033, respectively). CONCLUSIONS CDH1 downregulation acted as an independent prognostic biomarker in CN-AML patients.

J Cancer 2017; 8:460-468. [PMID: 28261348 PMCID: PMC5332898 DOI: 10.7150/jca.16914] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2016] [Accepted: 11/14/2016] [Indexed: 02/06/2023] Open
Abstract
AIM: The present study was aimed to investigate NKD2 expression as well as promoter methylation and further analyze their clinical significance in patients with acute myeloid leukemia (AML). METHODS: Real-time quantitative PCR was carried out to detect the pattern of NKD2 expression in 113 AML patients and 24 controls. Real-time quantitative methylation-specific PCR (RQ-MSP) and bisulfite sequencing PCR (BSP) were carried out to detect NKD2 promoter methylation in 101 AML patients and 24 controls with available DNA. RESULTS: The level of NKD2 transcript in AML patients was significantly down-regulated as compared with controls (P=0.039). NKD2 methylation level in AML patients was significantly higher than controls (P=0.044). Moreover, NKD2 methylation negatively correlated with NKD2 expression in AML patients (R=-0.218, P=0.029). Furthermore, demethylation of NKD2 could increase NKD2 expression in the leukemic cell line THP1 (P<0.05). NKD2 low-expressed and high-expressed patients showed no statistical significance in complete remission (CR) rate among cytogenetically normal AML (CN-AML). However, low NKD2 expression was associated with shorter overall survival (OS) time and acted as independent risk factor in CN-AML according to Kaplan-Meier (P=0.029) and Cox regression analyses (P=0.022). Furthermore, gene expression (GEP) data also confirmed the prognostic value of NKD2 expression in CN-AML patients. Moreover, NKD2 showed significantly increased level in post-CR than initial diagnosis in follow-up AML patients (P=0.024). CONCLUSION: Decreased NKD2 expression inactivated by promoter hypermethylation is a common event in AML and is associated with adverse outcome in CN-AML patients.

Abstract
BACKGROUND Hypermethylation of DLX4 (distal-less homeobox 4) has been disclosed in a variety of cancers. Our work was aimed to examine the pattern of DLX4 methylation and further investigate its clinical relevance in patients with myelodysplastic syndrome (MDS). METHODS Real-time quantitative methylation-specific PCR and bisulfite sequencing PCR were carried out to detect the level of DLX4 methylation. Clinical significance of DLX4 methylation was analyzed between the DLX4 hypermethylated and non-hypermethylated patients. RESULTS DLX4 was significantly hypermethylated in MDS patients than controls (p<0.001). No significant differences were observed between the hypermethylated and non-hypermethylated MDS patients in white blood cells, platelets, age, WHO classifications, FAB classifications, IPSS risks, and common gene mutations (p>0.05). However, DLX4 hypermethylated patients tended to have higher hemoglobin (HB) than DLX4 non-hypermethylated patients (p=0.079). Moreover, there was a trend that male patients, poor karyotype patients, and IPSS Int-2/High patients had a higher frequency of DLX4 hypermethylation (p=0.067, 0.065, and 0.068). DLX4 hypermethylated patients had significantly shorter overall survival than DLX4 non-hypermethylated patients (p=0.004). Multivariate analysis confirmed the prognostic value of DLX4 methylation in MDS patients (p<0.001). CONCLUSIONS Our study indicated that DLX4 hypermethylation was a frequent event and acted as an independent prognostic biomarker in de novo MDS patients.

Abstract
Background: Brain tumors, constituting one of the most deadly forms of cancer worldwide, result from the accumulation of multiple genetic and epigenetic alterations in genes and signaling pathways. Isocitrate dehydrogenase enzyme isoform 1 (IDH1) mutations are frequently identified in primary brain tumors and acute myeloid leukemia. Studies on IDH1 gene mutations have been extensively performed in various populations worldwide but not in Malaysia. This work was conducted to study the prevalence of IDH1 c.395G>A (R132H) hotspot mutations in a group of Malaysian patients with brain tumors in order to gain local data for the IDH1 mutation profile in our population. Methods: Mutation analysis of c.395G>A (R132H) of IDH1 was performed in 40 brain tumor specimens by the polymerase chain reaction-restriction fragment length polymorphism method (PCR-RFLP) and then verified by direct sequencing. Associations between the IDH1 c.395G>A (R132H) mutation and clinicopathologic characteristics were also analyzed. Results: The IDH1 c.395G>A (R132H) mutation was detected in 14/40 patients (35%). A significant association was found with histological tumor types, but not with age, gender and race. Conclusions: IDH1 is frequently mutated and associated with histological subtypes in Malay brain tumors.

Abstract
Epigenetic inactivation of GPX3 has been identified in various cancers including leukemia. Moreover, aberrant DNA methylation was also found as a dominant mechanism of disease progression in myelodysplastic syndrome (MDS). This study intended to explore GPX3 promoter methylation and its clinical relevance in 110 patients with MDS. GPX3 methylation was examined by real-time quantitative methylation-specific PCR (RQ-MSP) and bisulfite sequencing PCR (BSP). GPX3 methylation was identified in 15% (17/110) MDS patients, and significantly higher than controls, and lower than acute myeloid leukemia (AML) patients (P = 0.024 and 0.041). GPX3 methylated patients had older age and higher frequency of DNMT3A mutation (P = 0.015 and 0.066). Cases with GPX3 methylation showed significantly shorter overall survival (OS) time than those with GPX3 unmethylation analyzed with Kaplan-Meier analysis (P = 0.012). Moreover, Cox regression analysis revealed that GPX3 methylation might act as an independent prognostic indicator in MDS (HR = 1.847, P = 0.072). GPX3 methylation density was significantly increased during the progression from MDS to secondary acute myeloid leukemia (sAML) in three follow-up paired patients. Our study concludes that GPX3 methylation in bone marrow is associated with adverse prognosis and leukemia transformation in MDS.
