Abstract:

Background and purpose: T-cell acute lymphoblastic leukemia (T-ALL) is a type of blood malignancy caused by changes in the precursors of T lymphocyte cells. The PTEN gene is one of the most common tumor suppressor genes that mutates in most human cancers, including T-ALL. Therefore, it is important to identify miRNAs that target the PTEN gene in T-ALL. For this purpose, in the present study, miRNAs targeting PTEN gene in T-ALL patients were examined. Materials and methods: The miRNAs targeting PTEN was predicted and selected using bioinformatics. A total of 40 plasma samples were collected from T-ALL patients and healthy individuals. After RNA extraction and synthesis of cDNA, the expression levels of predicted miRNA and PTEN were assessed by Real time PCR in REST 2009. Statistical analysis was performed in SPSS V16 and P<0.05 were considered significant. Results: Bioinformatics showed that miR-1297 target the PTEN gene. Compared to healthy individuals, in T-ALL patients, the expression levels of miR-1297 and PTEN gene in the plasma significantly increased (45.93, P= 0.001) and decreased (0.191, P= 0.001), respectively. Conclusion: The present study showed that miR-1297 is likely to target the PTEN gene. Therefore, miR-1297 could serve as a new and non-invasive biomarker in diagnosis and treatment of T-ALL.

Expression of ROR1 Gene in Patients with Acute Lymphoblastic Leukemia

Background: Acute lymphoblastic leukemia (ALL) results from genetic alterations in a single lymphoid progenitor cell. Expression of ROR1 is reported to be increased in ALL and mantle cell lymphoma. In this study the expression of ROR1 was assessed in newly diagnosed patients with ALL.  Methods: This study was carried out on 40 patients with newly diagnosed ALL and healthy individuals as contro...

Diversity of T-cell receptor Gene Rearrangements in South Indian Patients with Common Acute Lymphoblastic Leukemia

Background: Precursor B-Acute Lymphoblastic Leukemia (precursor B-ALL) oc-curs due to the uncontrolled proliferation of B-lymphoid precursors arrested at a par-ticular stage of B-cell development. Precursor-B-ALL is classified mainly into pro-B-ALL, common-ALL and pre-B-ALL. The Common Acute Lymphoblastic Antigen CD10 is the marker for common-ALL. Objective: This study was aimed to examine the ...

DNA Methylation and the Expression of the Tumor-Suppressor Genes Protocadherin-10 and Reprimo in Pediatric Acute Lymphoblastic Leukemia

Background: Acute lymphoblastic leukemia (ALL) is the most prevalent hematologic malignancy among children. DNA methylation is well known to play a role in the initiation and progression of cancer. This research aimed to characterize the epigenetic inactivation and gene expression of Protocadherin-10 (PCDH10) and Reprimo (RPRM) in pediatric acute lymphoblastic leukemia, which is associated with...

Expression Analysis of Foxo3a Gene in Pediatric Acute Lymphoblastic Leukemia in Southern Iranian Population

Background: Acute lymphoblastic leukemia (ALL), the most common childhood cancer with a peak incidence in children from 2-5 years old, might be associated with poor prognosis and resistance to therapy in specific cytogenetic backgrounds. FoxO3a, a member of the forkhead class &lsquo;O&rsquo; (FoxO) transcription factors, is a main downstream target of PI3K/AKT pathway which regulates different ...

Significance of Cross Lineage Antigen Expression in Acute Lymphoblastic Leukemia

Background: Aberrant expression of cross-lineage antigens gives valuable insight into the diagnosis and prognosis of acute leukemia. In countries like India, cytogenetic tests are widely accessible. Exploring the prognostic value of an accessible test is of great importance. Therefore, establishing a population-specific immunophenotype database will enable to design an antibody panel equipped t...

The TAL1 complex targets the FBXW7 tumor suppressor by activating miR-223 in human T cell acute lymphoblastic leukemia

The oncogenic transcription factor TAL1/SCL is aberrantly expressed in 60% of cases of human T cell acute lymphoblastic leukemia (T-ALL) and initiates T-ALL in mouse models. By performing global microRNA (miRNA) expression profiling after depletion of TAL1, together with genome-wide analysis of TAL1 occupancy by chromatin immunoprecipitation coupled to massively parallel DNA sequencing, we iden...
