Project description:The gene expression of two different tumorigenic human breast epithelial cell types (HMLER and BPLER) is compared with their immortalized parental cell-of-origin (HME and BPE). Experiment Overall Design: Two different normal primary human mammary epithelial cell populations (BPECs and HMECs) were isolated based on their differing in vitro growth requirements. These cells were immortalized by hTERT giving rise to BPE and HME cells. These hTERT immortalized cells (BPE and HME) were transformed by SV40-early region (LT+st) and H-Ras giving rise to transformed tumorigenic derivatives BPLER and HMLER. Biological replicates (4 - 6 samples) for each of 4 cell types were analyzed (untransformed hTERT immortalized cell populations (BPE&HME), and transformed tumorigenic derivatives (BPLER & HMLER).

Project description:To investigate the mechanism of telomerase regulation in BCR-ABL positive cells due to its clinical value, we studied the catalytic component of telomerase, TERT. Our results suggest that BCR-ABL plays an important role in regulating hTERT in K562 (BCR-ABL positive human leukemia) cells. When Gleevec inhibited the tyrosine kinase activity of BCR-ABL, phosphorylation of hTERT was downregulated, therefore suggesting a positive correlation between BCR-ABL and hTERT. Gleevec treatment inhibited hTERT at the mRNA level and significantly reduced telomerase activity (TA) in K562 cells, but not in HL60 or Jurkat cells. TRAP assay also revealed that Gleevec treatment significantly reduced TA specifically in K562 cells. Furthermore, translocation of hTERT from nucleoli to nucleoplasm was observed in K562 cells induced by Gleevec. Although Gleevec down-regulated hTERT mRNA level, the protein level of hTERT remained unchanged. Therefore, Gleevec-induced-TA decrease is not due to the alteration in telomerase subunits expression. It could be presumably due to posttranslational modification of hTERT, possibly through multiple signaling pathways. We have found that Gleevec reduced the tyrosine phosphorylation of hTERT by BCR-ABL, which is associated with the nucleoplasm localization of hTERT from nucleoli sequesters. These findings reveal unknown functions and regulations of telomerase by BCR-ABL.
