Molecular analysis of the T-cell acute lymphoblastic leukemia-associated t(1;7)(p34;q34) that fuses LCK and TCRB.

Previously we had characterized the t(1;7)(p34;q34) translocation from HSB-2. This translocation fused the beta T-cell receptor gene (TCRB) constant region and transcriptional enhancer with the type I transcription unit of the LCK gene on the derivative 1 [der(1)] chromosome. The type II promoter was translocated to the der(7) chromosome. Regarding the mechanism of the t(1;7) in HSB-2, we ident...

The molecular basis of T cell acute lymphoblastic leukemia.

T cell acute lymphoblastic leukemias (T-ALLs) arise from the malignant transformation of hematopoietic progenitors primed toward T cell development, as result of a multistep oncogenic process involving constitutive activation of NOTCH signaling and genetic alterations in transcription factors, signaling oncogenes, and tumor suppressors. Notably, these genetic alterations define distinct molecul...

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 ...

Chromosomal translocations joining LCK and TCRB loci in human T cell leukemia

A case of T lymphoblastic leukemia (T-ALL) showing t(1;7)(p34;q34) as the sole karyotypic abnormality was investigated at the molecular level. Screening of a phage library of tumor DNA with a probe for the beta T cell receptor gene (TCRB), which maps to chromosomal band 7q34, resulted in the isolation of a clone containing DNA spanning the translocation breakpoint of the der(1) chromosome. This...

Effects of valproic acid and pioglitazone on cell cycle progression and proliferation of T-cell acute lymphoblastic leukemia Jurkat cells

Objective(s): T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematologic malignant tumor. Administration of chemical compounds influencing apoptosis and T cell development has been discussed as promising novel therapeutic strategies. Valproic acid (VPA) as a recently emerged anti-neoplastic histone deacetylase (HDAC) inhibitor and pioglitazone (PGZ) as a high-affinity peroxisome p...
