Lin J, Yang J, Xu X, Wang Y, Yu M, Zhu Y. A robust 11-genes prognostic model can predict overall survival in bladder cancer patients based on five cohorts. Cancer Cell Int 2020; 20:402. [PMID: 32843852 PMCID: PMC7441568 DOI: 10.1186/s12935-020-01491-6] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Accepted: 08/10/2020] [Indexed: 12/25/2022] Open
Abstract
Background Bladder cancer is the tenth most common cancer globally, but existing biomarkers and prognostic models are limited. Method In this study, we used four bladder cancer cohorts from The Cancer Genome Atlas and Gene Expression Omnibus databases to perform univariate Cox regression analysis to identify common prognostic genes. We used the least absolute shrinkage and selection operator regression to construct a prognostic Cox model. Kaplan-Meier analysis, receiver operating characteristic curve, and univariate/multivariate Cox analysis were used to evaluate the prognostic model. Finally, a co-expression network, CIBERSORT, and ESTIMATE algorithm were used to explore the mechanism related to the model. Results A total of 11 genes were identified from the four cohorts to construct the prognostic model, including eight risk genes (SERPINE2, PRR11, DSEL, DNM1, COMP, ELOVL4, RTKN, and MAPK12) and three protective genes (FABP6, C16orf74, and TNK1). The 11-genes model could stratify the risk of patients in all five cohorts, and the prognosis was worse in the group with a high-risk score. The area under the curve values of the five cohorts in the first year are all greater than 0.65. Furthermore, this model's predictive ability is stronger than that of age, gender, grade, and T stage. Through the weighted co-expression network analysis, the gene module related to the model was found, and the key genes in this module were mainly enriched in the tumor microenvironment. B cell memory showed low infiltration in high-risk patients. Furthermore, in the case of low B cell memory infiltration and high-risk score, the prognosis of the patients was the worst. Conclusion The proposed 11-genes model is a promising biomarker for estimating overall survival in bladder cancer. This model can be used to stratify the risk of bladder cancer patients, which is beneficial to the realization of individualized treatment.

[PMID: 32314545 PMCID: PMC7294116 DOI: 10.1111/jcmm.15117] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Revised: 02/08/2020] [Accepted: 02/15/2020] [Indexed: 12/30/2022] Open
Abstract
Cervical cancer is one of the major malignancies, the pathophysiology and progression of which remain to be scarcely understood. Long non-coding RNAs (lncRNAs) have been previously implicated in the progression of cervical cancer. Here, the purpose of this study was to identify whether lncRNA heart- and neural crest derivative-expressed 2-antisense RNA 1 (HAND2-AS1) affect the development of cervical cancer through regulation of chromosome 16 open reading frame 74 (C16orf74) by mediating a transcription factor E2F4. RT-qPCR was performed to determine the expression of HAND2-AS1 in cervical cancer cells. Then, cervical cancer cells were treated with HAND2-AS1 or si-E2F4 RNA, or C16orf74, after which the proliferation, colony formation, migration and invasion were detected. Moreover, the binding between HAND2-AS1 and E2F4 or between E2F4 and C16orf74 was explored. Finally, the tumorigenesis of cervical cancer cells was measured in nude mice with altered HAND2-AS1/E2F4/C16orf74 expression. HAND2-AS1 exhibited poor expression in cervical cancer, and HAND2-AS1 overexpression suppressed the proliferation, colony formation, migration and invasion of cervical cancer cells. In addition, HAND2-AS1 was found to recruit transcription factor E2F4 to C16orf74 promoter region and down-regulate C16orf74 expression. Lastly, HAND2-AS1/E2F4/C16orf74 modulated the tumorigenesis of cervical cancer in nude mice. In conclusion, this study provided evidence on the inhibitory effect of HAND2-AS1 on the development of cervical cancer through the suppression of C16orf74 expression by recruiting transcription factor E2F4. This study highlights the potential of lncRNA HAND2-AS1 as a target in the treatment of cervical cancer.

Role of Dimerized C16orf74 in Aggressive Pancreatic Cancer: A Novel Therapeutic Target. Mol Cancer Ther 2020; 19:187-198. [PMID: 31597713 DOI: 10.1158/1535-7163.mct-19-0491] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2019] [Revised: 07/27/2019] [Accepted: 10/03/2019] [Indexed: 11/16/2022]
Abstract
Over the past 30 years, the therapeutic outcome for pancreatic ductal adenocarcinoma (PDAC) has remained stagnant due to the lack of effective treatments. We performed a genome-wide analysis to identify novel therapeutic targets for PDAC. Our analysis showed that Homo sapiens chromosome 16 open reading frame 74 (C16orf74) was upregulated in most patients with PDAC and associated with poor prognosis. Previously, we demonstrated that C16orf74 interacts with the catalytic subunit alpha of protein phosphatase 3 and plays an important role in PDAC invasion. However, the pathophysiologic function of C16orf74 is still unclear. In this study, through the analysis of C16orf74 interaction, we demonstrate a new strategy to inhibit the growth and invasion of PDAC. C16orf74 exists in the homodimer form under the cell membrane and binds integrin αVβ3 and is also involved in invasion by activating Rho family (Rac1) and MMP2. Considering that this dimeric form was found to be involved in the function of C16orf74, we designed an 11R-DB (dimer block) cell-permeable dominant-negative peptide that inhibits the dimer form of C16orf74. 11R-DB suppressed invasion and proliferation of PDAC cell lines by inhibiting phosphorylation of Akt and mTOR and also by inactivation of MMP2. 11R-DB also showed antitumor effects in an orthotopic xenograft model and peritoneal metastasis model. Thus, this study demonstrates that dimerized C16orf74, present in the cell membrane, is involved in pancreatic cancer invasion and proliferation. In addition, the C16orf74 dimer block cell-permeable peptide (11R-DB) has a potent therapeutic effect on PDAC in vitro and in vivo.

Overexpression of C16orf74 is involved in aggressive pancreatic cancers. Oncotarget 2016; 8:50460-50475.

Abstract
Clinical outcome of pancreatic ductal adenocarcinoma (PDAC) has not been improved in the last three decades due to the lack of effective molecular-targeted drugs. To identify a novel therapeutic target for PDAC, we have performed genome-wide anamysis and found that Homo sapienschromosome 16 open reading frame 74 (C16orf74) was up-regulated in the vast majority of PDAC. Overexpression of C16orf74protein detected by immunohistochemical analysis was an independent prognostic factor for patients with PDAC. The knockdown of endogenous C16orf74 expression in the PDAC cell lines KLM-1 and PK-59 by vector-based small hairpin-RNA (shRNA) drastically attenuated the growth of those cells, whereas ectopic C16orf74 overexpression in HEK293T and NIH3T3 cells promoted cell growth and invasion, respectively. More importantly, the endogenous threonine 44 (T44)-phosphorylated form of C16orf74 interacted with the protein phosphatase 3 catalytic subunit alpha (PPP3CA) via the PDIIIT sequence in the PPP3CA-binding motif within the middle portion of C16orf74 in PDAC cells. The overexpression of mutants of C16orf74 lacking the PDIIIT sequence or T44 phosphorylation resulted in the suppression of invasive activity compared with wild-type C16orf74, indicating that their interaction should be indispensable for PDAC cell invasion. These results suggest that C16orf74 plays an important role for PDAC invasion and proliferation, and is a promising target for a specific treatment for patients with PDAC.

Abstract
OBJECTIVE The aim of this study was to analyze tumour gene expression profiles of progressive and non-progressive T1G3 bladder cancer (BC) patients to develop a gene expression signature to predict tumour progression. METHODS Retrospective, multicenter study of 96 T1G3 BC patients without carcinoma in situ (CIS) who underwent a transurethral resection. Formalin-fixed paraffin-embedded tissue samples were collected. Global gene expression patterns were analyzed in 21 selected samples from progressive and non-progressive T1G3 BC patients using Illumina microarrays. Expression levels of 94 genes selected based on microarray data and based on literature were studied by quantitative polymerase chain reaction (qPCR) in an independent series of 75 progressive and non-progressive T1G3 BC patients. Univariate logistic regression was used to identify individual predictors. A variable selection method was used to develop a multiplex biomarker model. Discrimination of the model was measured by area under the receiver-operating characteristic curve. Interaction networks between the genes of the model were built by GeneMANIA Cytoscape plugin. RESULTS A total of 1294 genes were found differentially expressed between progressive and non-progressive patients. Differential expression of 15 genes was validated by qPCR in an additional set of samples. A five-gene expression signature (ANXA10, DAB2, HYAL2, SPOCD1, and MAP4K1) discriminated progressive from non-progressive T1G3 BC patients with a sensitivity of 79% and a specificity of 86% (AUC = 0.83). Direct interactions between the five genes of the model were not found. CONCLUSIONS Progressive and non-progressive T1G3 bladder tumours have shown different gene expression patterns. To identify T1G3 BC patients with a high risk of progression, a five-gene expression signature has been developed.

Abstract
PURPOSE Our previous high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry study identified bladder cancer (BCA)-specific urine metabolites, including carnitine, acylcarnitines, and melatonin. The objective of the current study was to determine which metabolic pathways are perturbed in BCA, based on our previously identified urinary metabolome. MATERIALS AND METHODS A total of 135 primary BCA samples and 26 control tissue samples from healthy volunteers were analyzed. The association between specific urinary metabolites and their related encoding genes was analyzed. RESULTS Significant alterations in the carnitine-acylcarnitine and tryptophan metabolic pathways were detected in urine specimens from BCA patients compared to those of healthy controls. The expression of eight genes involved in the carnitine-acylcarnitine metabolic pathway (CPT1A, CPT1B, CPT1C, CPT2, SLC25A20, and CRAT) or tryptophan metabolism (TPH1 and IDO1) was assessed by RT-PCR in our BCA cohort (n=135). CPT1B, CPT1C, SLC25A20, CRAT, TPH1, and IOD1 were significantly downregulated in tumor tissues compared to normal bladder tissues (p<0.05 all) of patients with non-muscle invasive BCA, whereas CPT1B, CPT1C, CRAT, and TPH1 were downregulated in those with muscle invasive BCA (p<0.05), with no changes in IDO1 expression. CONCLUSION Alterations in the expression of genes associated with the carnitine-acylcarnitine and tryptophan metabolic pathways, which were the most perturbed pathways in BCA, were determined.

Abstract
In this study, we detected the expression profiles of microRNAs (miRNAs) packaged within microvesicles (MVs) from blood samples of HCC patients and healthy donors. Using microarray analysis, there were 83 down-regulated and 92 over-expressed miRNAs in HCC circulation-derived MVs relative to control group. Then potential functions of the dysregulated MVs miRNAs were investigated with bioinformatic tools. We found that 664 Corf genes were targeted by 72 altered MVs miRNAs and some of these target genes were reported to be associated with tumorous activities. Gene Ontology annotation demonstrated that biological roles of the target Corf genes mainly contained the regulation of growth, cell death, macromolecule metabolism, etc. As regulated by abnormal MVs miRNAs, functions of target Corf genes might be interrupted, which were much likely to contribute to HCC occurrence and progression.

Abstract
OBJECTIVES MicroRNAs (miRNAs) are small, non-coding RNAs that have been increasingly shown important roles in various classes of cancers. However, miR-1269 has not been comprehensively studied in hepatocellular carcinoma (HCC). Thus, the purpose of the study was to evaluate the relationship between the expression of miR-1269 and clinicopathological parameters in HCC patients, and to predict its potential target genes. METHODS Total RNA was extracted from 95 pairs of HCC and matching adjacent non-cancerous tissues. The level of miR-1269 expression was detected by using quantitative real-time RT-PCR and calculated with the 2(-ΔCq) method. Eighteen online biological databases were used for targets prediction. RESULTS MiR-1269 expression was up-regulated in HCC tissues (1.9264±0.7160) compared to their non-tumor livers (1.5518±0.7273, P < 0.001). Level of miR-1269 was positively correlated to tumor nodes (r = 0.206, P = 0.046), metastasis (r = 0.203, P = 0.049), portal vein tumor embolus (r = 0.247, P = 0.016), vaso-invasion (r = 0.273, P = 0.008), tumor capsular infiltration (r = 0.407, P < 0.001) and expression of MTDH (r = 0.211, P = 0.005). Finally, 7 databases could be applied for the target prediction successfully. There were 9 targeted genes which had been shown concurrently by at least 4 databases: AGAP1, AGK, BPTF, C16orf74, DACT1, LIX1L, RBMS3, ZNF706 and BMPER. CONCLUSIONS MiR-1269 may be possibly involved in the tumorigenesis and progress of HCC. MiR-1269 could also act as a potential biomarker for the prognosis prediction for HCC.

Abstract
Background CDH13 is a novel tumor suppressor gene often inactivated by aberrant promoter methylation in human cancers. Previous studies have shown that CDH13 methylation correlated with advanced disease and poor prognosis in non-muscle invasive bladder cancer (NMIBC). The aim of the current study was to investigate the correlations between CDH13 methylation and disease recurrence as well as progression of NMIBC. Material/Methods The methylation status of CDH13 in 178 NMIBC samples and 38 normal bladder epithelial tissues was examined by methylation-specific PCR (MSP), and then correlated with clinicopathological features. Results We found that CDH13 methylation occurs frequently in NMIBC, and significantly correlates with high grade, advanced stage, larger tumor size, and tumor recurrence and progression. Moreover, patients with methylated CDH13 exhibited significantly shorter recurrence-free survival (P<0.0001) and progression-free survival (P=0.0060) than patients with unmethylated CDH13. In addition, a multivariate Cox proportional hazard model analysis suggests that CDH13 methylation is an independent predictor for the recurrence (P=0.0043) and progression (P=0.0016) of NMIBC after initial transurethral resection. Conclusions Our findings demonstrate that CDH13 methylation is a frequent event in NMIBC, and is associated with unfavorable tumor features. It should be used as an independent predictor for the recurrence and progression of NMIBC, and may be useful for the design of individualized therapeutic modalities.

Abstract
To identify prognostic markers in nonmuscle invasive bladder cancer (NMIBC), the combined effect of RUNX3 and MGC17624 for predicting NMIBC progression was assessed. RUNX3 promoter methylation was examined using methylation specific-polymerase chain reaction (MS-PCR). MGC17624 mRNA expression was evaluated by real-time PCR. Patients were divided into three groups according to the status of the two genes and the prognostic effects of these markers were evaluated. The median follow-up period was 57.8 months (range, 9.1-189.7). The mRNA expression level of MGC17624 was significantly lower in patients with positive RUNX3 methylation than in those with negative methylation (p = 0.047). Kaplan-Meier estimates showed significant differences in time-to-progression between the genetic combination predictors (log-rank test; p < 0.001). Patients with a poor predictive combination were at a significantly higher risk for progression [Hazard ratio (HR), 22.579] than patients with a good predictive combination in multivariate Cox regression analysis. In the subgroup analysis, a poor predictive combination accurately estimated progression in patients with intravesical therapy (HR, 20.081) and in those who experienced recurrence (HR, 54.233). Assessment of the status of RUNX3 and MGC17624 in combination was identified as a reliable method for predicting NMIBC progression.
