  • 摘要:Chromosomal rearrangements in malignant T-cell disease frequently involve the chromosome bands containing the T-cell receptor genes. The RPMI 8402 cell line, which was established from the leukemia cells of a patient with T-cell acute lymphoblastic leukemia, is characterized by a translocation involving chromosome 14 (band q11) and chromosome 11 (band p15) [t(11;14)(p15;q11)]. By using in situ chromosomal hybridization and Southern blot analysis to examine RPMI 8402 cells, we determined that the break at 14q11 occurs within the variable region sequences of the T-cell receptor alpha-chain gene (TCRA); the break at 11p15 occurs between the HRAS1 gene and the genes for insulin and the insulin-like growth factor 2. These results suggest that the TCRA sequences activate a cellular gene located at 11p15 in malignant T-cell disorders.
