Abstract
Simultaneous quantitative measurement of mRNA of the WT1, BAALC, EVI1, PRAME and HMGA2 genes in whole blood samples reflects the specific pathological proliferative activity in acute leukemia and their ratio is promising as a diagnostic marker. The transcriptome profile of acute leukemia cells is usually assessed using NGS or microarray techniques after a preliminary procedure for isolation of mononuclear cells. However, the results of using the multiplex PCR reaction for the simultaneous determination of all above mRNAs in whole blood samples have not been published so far. Determination of mRNA of WT1, BAALC, EVI1, PRAME and HMGA2 genes in venous blood level samples by multiplex RT-PCR. The study included 127 blood samples from patients who diagnosis of acute leukemia was subsequently confirmed. In the comparison group, 87 samples of patients without oncohematological diagnosis were selected, including 31 samples (K1) with a normal blood formula and 56 samples (K2) with a violation of the cellular composition - anemia, leukocytosis and thrombocytopenia. RNA isolation and reverse transcription were performed using the Ribozol-D and Reverta-L kits (TsNIIE, Russia). Determination of the mRNA expression level of the WT1, BAALC, EVI1, PRAME and HMGA2 genes by multiplex real-time PCR using a homemade multiplex PCR kit. The mRNA level was characterized by high interindividual variation and did not correlate with the rate of circulating leukocytes or blood blasts. Expression of WT1 mRNA was observed in whole blood only in one patient from the control group and in 112 (88%) patients with leukemia and was combined with a decrease in the level of HMGA2 mRNA expression and BAALC mRNA values. In contrast to the control groups, patients with leukemia had higher levels of BAALC mRNA in AML and ALL, increased PRAME mRNA in AML and APL, but lower levels of HMGA2 in APL.

Abstract
Acute myeloid leukemia with normal cytogenetics (CN-AML) is the largest group of AML patients which is associated with a variegated patient outcome. Multiple molecular markers have been used to risk-stratify these patients. Estimation of expression of BAALC gene (Brain and Acute Leukemia, Cytoplasmic) mRNA level is one of the predictive markers which has been identified in multiple studies. In this study, we examined the clinical and prognostic value of BAALC gene expression in 149 adult CN-AML patients. We also utilized multi-omics databases to ascertain the association of BAALC gene expression with comprehensive molecular and clinicopathologic features in AML. BAALC overexpression was associated with CD34 positivity on leukemic blasts (p = 0.0026) and the absence of NPM1 gene mutation (p < 0.0001), presence of RUNX1 gene mutation (p < 0.001) and poor patient outcomes, particularly in NPM1-wild type/FLT3-ITD negative adult CN-AML patients. Additionally, BAALC expression was associated with the alteration of methylation of its promoter. Further, pathway analysis revealed that BAALC expression is correlated with MYC targets and Ras signalling. We conclude that high BAALC expression associates with poor patient outcome in NPM1-wild type/FLT3-ITD negative adult CN-AML patients.

Abstract
OBJECTIVES This meta-analysis examined the prognostic role of brain and acute leukemia, cytoplasmic (BAALC), Ecotropic virus integration site-1 (EVI1) and Wilms' tumor 1 (WT1) genes at different time-points during conventional chemotherapy. METHODS A systematic search of publications indexed in the electronic databases from January 1988 to October 2020 was performed. Over 7525 cases of AML from 25 studies were involved. RESULTS At diagnosis, overexpression of either BAALC or EVI1 had a negative impact on complete remission achievement (Summary Odds ratios [SORs] for BAALC = 0.32; SORs for EVI1 = 0.49) and survival outcome. The summary hazard ratios of overall survival (OS) and disease-free survival (DFS) were 1.97 and 2.04 for BAALC and 1.33 and 1.86 for EVI1, respectively. The prognostic value of pretreatment WT1 levels was heterogeneous while subgroup analyses unveiled that overexpressed WT1 may correlate with a favorable outcome (summary hazard ratio [SHR] for OS = 0.42). Both WT1 and BAALC played a role in prognosis assessment at post-induction and the diagnostic performance of WT1 transcript reduction was superior to the absolute WT1 level. Post-consolidation WT1 overexpression consistently indicated an increased risk of relapse, while the combined HR for RFS was statistically insignificant (SHR = 4.22). CONCLUSION These findings confirm the application of BAALC and EVI1 at diagnosis, WT1 after induction chemotherapy in AML patients throughout conventional chemotherapy.

Abstract
Purpose: Acute myeloid leukemia (AML) is the most prevalent acute leukemia in adults. It possesses different cytogenetic and molecular features. The expression of Wilms tumor-1 (WT1), brain and acute leukemia, cytoplasmic (BAALC) and ETS-related gene (ERG) might be considered as prognostic factors in AML patients. The aim of this study was to determine the mRNA expressions of WT-1, BAALC and ERG genes in bone marrow of mononuclear cells and their effects on complete remission in the Iranian AML patients, pre- and post- chemotherapy. Methods: Forty AML patients with normal karyotype were evaluated. The mRNA gene expressions were measured with quantitative real-time PCR in bone marrow of mononuclear cells of AML patients at the baseline and after chemotherapy. The subtypes of AML and flow cytometry panel were also assessed. Complete remission (CR) after the treatment was addressed for all patients. Results: The mRNA expressions of WT-1, BAALC and ERG were significantly decreased after the treatment (p = 0.001, 0.017, 0.036). WT-1 mRNA expression was inversely correlated with CR after chemotherapy (P =0.024). There was also significant correlation between baseline expression of BAALC and CR (P =0.046). No significant correlation was observed between ERG and CR pre- and post- chemotherapy (P =0.464 and 0.781). There was also significant correlation between BAALC mRNA expression and CD34+ (P <0.001). Conclusion: The present study showed that WT-1 decreased significantly after standard chemotherapy which could have favorable effects on CR. Also, the high expression of BAALC could have a poor prognostic role in AML patients. The identification of these gene expressions can be an efficient approach in targeted therapy among AML patients.

Abstract
The high expression of brain and acute leukemia, cytoplasmic (BAALC) and ETS-related gene (ERG) has been reported to influence the outcome in acute myeloid leukemia (AML), but due to limited prospective studies, their role as prognostic factors is unclear. At diagnosis, the prognostic value of BAALC and ERG expression with respect to other cytogenetic and molecular markers was analyzed in 149 AML patients. Patients were divided into quartiles which resulted in the formation of four groups (G1-G4) based on expression values of BAALC and ERG and clinical response defined across groups. Groups with similar survival probabilities were merged together and categorized subsequently as high versus low expressers. Patients with high BAALC and ERG expression had significantly lower overall survival (OS; BAALC: p = 0.001 at 5 years 29.4% vs. 69.8%; ERG: p < 0.0001 at 5 years 4% vs. 50.4%) and disease-free survival (BAALC: p = 0.001 at 5 years 19.5% vs. 69.8%; ERG: p < 0.0001 at 5 years 4.2% vs. 47%). Patients were further stratified combining BAALC and ERG expression in an integrative prognostic risk score (IPRS). After a median follow-up of 54 months (95% CI 45-63 months) among survivors, IPRS for high versus low expressers was a significant predictor for OS (BAALC + ERG: 4% vs. 71.6%, p < 0.0001) and DFS (BAALC + ERG: 4.5% vs. 74.1%, p < 0.0001). In a multivariate model, IPRS of BAALC + ERG expression retained prognostic significance for OS (hazard ratio [HR] 2.96, 95%CI 1.91-4.59, p < 0.001) and DFS (HR 3.61, 95%CI 2.26-5.76, p < 0.001).

Abstract
Acute myeloid leukemia (AML) is the most common hematological malignancy among adults and is characterized by accumulation of immature myeloid cells. Different genetic factors have role in the occurrence of AML. Among different proteins, RUNX1 and BAALC are involved in the development AML. It has been shown that BAALC overexpression is a factor that indicate shorter disease free survival in a subset of AML patients. RUNX1 has been implicated in the development of breast, prostate, lung, and skin cancers. The aim of this study is determination of the prevalence of common polymorphisms in BAALC (rs6999622 and rs62527607) and RUNX1 (rs13051066 and rs61750222) in AML patients compared with healthy subjects. A total of 100 AML patients and 100 healthy control subjects were included in our study. Genomic DNA was isolated from peripheral blood and the polymorphisms were genotyped by applying ARMS and PCR-RFLP methods. Finally, data was analyzed using SPPSS software. Our results demonstrate a significant association between the RUNX1 rs13051066 and AML in the co-dominant (odd ratio = 6.66, 95% Cl = 1.85-25, p = .006) and dominant (GT + TT versus GG: odd ratio = 6.15, 95% CI = 1.73-21.87, p = .002) models. The RUNX1 rs13051066 polymorphism is associated with risk of AML in Iranian population. Future studies should consider larger sample size for assessment of RUNX1 gene polymorphisms, and employ cytogenetic and molecular analyses in AML patients from different ethnic origins.

Abstract
The aim of this work is to investigate the different expression patterns of B cell-specifics moloney murine Leukemia virus integration site-1 (BMI-1) and brain and acute leukemia, cytoplasmic (BAALC) genes, their prognostic and clinical significance in newly diagnosed cytogenetically heterogenous adult acute myeloid leukemia patients. BMI-1 and BAALC expression was detected in the bone marrow of patients using quantitative real-time reverse transcription polymerase chain reaction with cut off value set at 50th percentile for both genes. BMI-1 and BAALC overexpression was detected in 50% of cases which suggest their potential as molecular markers. A statistical significant correlation was found between BMI-1 expression with hepatomegaly (P value = 0.007), hemoglobin level-grouped (P value = 0.047) and cytogenetic risk groups (P value = 0.036). There was a statistically significant correlation between BAALC and age (P value = 0.015), lymphadenopathy (P value = 0.043), CD34 expression (P value = 0.003) and near statistical significance with FAB sub-groups (P value = 0.054). No statistical significance was noted for other hematological findings and response to treatment except for BAALC gene and treatment response (P value = 0.014). No statistical significance in overall survival and disease free survival for both genes was found. Their prospective screening in combination with other molecular markers can help refine myeloid leukemia staging and prognosis toward optimizing therapeutic interventions.

Abstract
Acute myeloid leukemia (AML) is associated with the sequential accumulation of acquired genetic alterations. Although at diagnosis cytogenetic alterations are frequent in AML, roughly 50% of patients present an apparently normal karyotype (NK), leading to a highly heterogeneous prognosis. Due to this significant heterogeneity, it has been suggested that different molecular mechanisms may trigger the disease with diverse prognostic implications. We performed whole-exome sequencing (WES) of tumor-normal matched samples of de novo AML-NK patients lacking mutations in NPM1, CEBPA or FLT3-ITD to identify new gene mutations with potential prognostic and therapeutic relevance to patients with AML. Novel candidate-genes, together with others previously described, were targeted resequenced in an independent cohort of 100 de novo AML patients classified in the cytogenetic intermediate-risk (IR) category. A mean of 4.89 mutations per sample were detected in 73 genes, 35 of which were mutated in more than one patient. After a network enrichment analysis, we defined a single in silico model and established a set of seed-genes that may trigger leukemogenesis in patients with normal karyotype. The high heterogeneity of gene mutations observed in AML patients suggested that a specific alteration could not be as essential as the interaction of deregulated pathways.

Abstract
Acute lymphoblastic leukemia (ALL) is characterized by excess bone marrow lymphoblast cell production. Brain and Acute Leukemia Cytoplasmic gene (BAALC gene) is a recently identified gene on chromosome 8q22.3. The aim of this work was to study the role of BAALC gene in prognosis of ALL in Egyptian children. This study was conducted on 60 children with ALL who were admitted in Oncology Unit in the period from January 2012 to March 2015 including 36 males and 24 females with mean age of 8.74 ± 2.66 years. For all patients the following were done: Full history taking, thorough clinical examination and laboratory investigations including: complete blood count, LDH, bone marrow aspiration, cytochemistry, immunophenotyping, FISH technique for detection of t(12;21) and t(9;22) and assessment of BAALC gene expression by PCR in bone marrow aspirate mononuclear cells at diagnosis before chemotherapy. Positive BAALC gene expression was found in 36 patients (60%) and negative expression in 24 patients (40%). Positive BAALC gene expression group includes 14 males and 22 females with mean age at presentation of 8.45 ± 2.77 years while negative BAALC gene expression group includes 18 males and 6 females with mean age at presentation of 8.61 ± 2.44 years with no significant differences between positive and negative BAALC gene expression groups regarding age, sex, clinical presentations, WBCs and platelets counts, hemoglobin and LDH levels, peripheral blood and BM blast cell counts, immunophenotyping and chromosomal translocations including t(12;21) and t(9;22). There were significant differences in disease outcome between positive and negative BAALC gene expression groups with higher rate of relapse and death and lower rate of complete remission, disease free survival (DFS) and overall survival (OS) in positive BAALC gene expression group compared with negative group (p = 0.028). Multivariate analyses for overall survival and disease free survival shows significant role of BAALC gene expression in OS and DFS. BAALC expression might represent an additional prognostic marker in children with ALL and should be routinely assessed at diagnosis for better prognostic assessment.

Application of the AMLprofiler Diagnostic Microarray in the South African Setting. Stem Cells Int 2017; 2017:2560191. [PMID: 29238371 PMCID: PMC5697127 DOI: 10.1155/2017/2560191] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2017] [Revised: 08/09/2017] [Accepted: 10/12/2017] [Indexed: 11/17/2022] Open
Abstract
Acute myeloid leukemia (AML) is characterized by proliferation of the myeloid lineage and accumulation of immature hematopoietic cells in the bone marrow and is typified by marked heterogeneity both in response to treatment and survival. AMLprofiler is a qualitative in vitro diagnostic microarray incorporating seven molecular biomarkers used to diagnose and predict posttherapy survival rates. In this study, we compared AMLprofiler to routine AML diagnostic methodologies employed in South Africa, focusing on consistency of the results, cost, and time to result. RNA was isolated from bone marrow and peripheral blood samples from patients with de novo AML and was processed using Affymetrix Gene Profiling Reagent kits. The results from AMLprofiler and standard methodologies were highly comparable. In addition, many samples were determined to be positive for biomarkers not routinely investigated in South Africa, namely, CEBPA double mutants, NPM1 variants, and altered expression levels of BAALC and EVI1. 38% of samples presented with no positive biomarker; AMLprofiler nonetheless enabled 26% of AML patients to be classified into either favorable or poor prognostic categories. This study highlights the comprehensive nature of the microarray. Decreased time to result and refinement of risk stratification are notable benefits.
