Telomerase enzymatic component hTERT shortens long telomeres in human cells.
Telomere lengths are tightly regulated within a narrow range in normal human cells. Previous studies have extensively focused on how short telomeres are extended and have demonstrated that telomerase plays a central role in elongating short telomeres. However, much about the molecular mechanisms of regulating excessively long telomeres is unknown. In this report, we demonstrated that the telome...
متن کاملOpposing regulatory roles of E2F in human telomerase reverse transcriptase (hTERT) gene expression in human tumor and normal somatic cells.
Telomerase activity is closely correlated with cellular proliferative activity in human tissues. Human cells with high proliferative potential, such as tumor cells or stem cells, exhibit telomerase activity, whereas most normal human somatic cells do not. Telomerase activity is tightly regulated by the expression of its catalytic subunit human telomerase reverse transcriptase (hTERT). Through a...
متن کاملEvaluation of MLL2 (KMT2B) Gene Expression in Colorectal Cancer Tissue Compared with Adjacent Tumor Free Tissue
Background and Aims: An impairment of expression in MLL2 gene involved in histone methylation induces alteration in the methylation patterns at enhancers and causes several cancers including colon cancer. In this study, MLL2 expression was evaluated in North West of Iran. Materials and Methods: To evaluate the MLL2 expression in patients with colon cancer, 25 tumor samples and 25 samples of tu...
متن کاملcluster and principal component analysis of human glioblastoma multiforme (gbm) tumor proteome and principal component analysis of human glioblastoma multiforme (gbm) tumor proteome
background : glioblastoma multiforme (gbm) or grade iv astrocytoma is the most common and lethal adult malignant brain tumor. several of the molecular alterations detected in gliomas may have diagnostic and/or prognostic implications, proteomics has been widely applied in various areas of science, ranging from the deciphering of molecular pathogen nests of discuses. method: we extracted protein...
متن کاملInduction of apoptosis in human tumor cell lines by platelets
Introduction: It has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. The effect of platelets on the induction of apoptosis in tumor cells is largely unknown. Materials and methods: To investigate this effect, two human hematologic cell lines, K562 and Daudi, were independently faced with unstimulated and thromb...
