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

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 ...

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...

Taq1 Polymorphism (rs731236) of Vitamin D Receptor Gene in Children with Acute Lymphoblastic Leukemia

Background: Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Several studies have shown that ALL occurs as a result of genetic abnormalities. 1, 25-Dihydroxyvitamin D3 as a secosteroid hormone plays an important role in different metabolic pathways. The normal function of vitamin D occurs via binding to a ligand-activated transcription factor i.e. vitamin D receptor (VDR)...

Prolonged Vincristine Toxicity Induced by Concurrent Posaconazole in a Child with T-cell Acute Lymphoblastic Leukemia

High frequency of cryptic chromosomal rearrangements involving the LMO2 gene in T-cell acute lymphoblastic leukemia.

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive malignancy of thymocytes resulting from the transformation of T-cell progenitors. Around half of T-ALL patients harbor recurrent cytogenetic alterations, including juxtaposition of strong promoters and enhancers located in the TCRB (chr. 7q34) or TCRA-TCRD (chr. 14q11) loci with a variety of oncogenic transcription factors, such as LI...

Changes in Expression of miR-1297 and PTEN Tumor Suppressor Gene in T-cell Acute Lymphoblastic Leukemia

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, mi...
