Telomerase Activity in Cervical Cancer Expression of Human Telomerase Subunits and Correlation
Activation of telomerase and stabilization of telomeres are thought to be required for both cellular immortality and oncogenesis. Three major components of human telomerase, human telomerase RNA (hTR), telomerase-associated protein (TP1/TLP1), and human telomerase catalytic subunit (hTRT/hEST2), have been identified recently. However, it re mains unclear what roles these subunits play in the re...

متن کاملMammalian telomerase: catalytic subunit and knockout mice.
For the second time this year random cDNA sequencing, in combination with data from unicellular eukaryotes, has made a significant contribution to the analysis of human telomerase. Two groups have reported mammalian homologues of the Tetrahymena p80 telomerase-associated protein, in both cases the key breakthrough being mammalian cDNA clones with database matches to Tetrahymena p80. This has no...
متن کاملTelomerase Activity in Cervical Smears
It is well known that almost all carcinoma cells including those of the uterine cervix have re-established their telomerase activity. However, until now there is no conclusive picture on the telomerase activity in cervical dysplasias and about their relationship to HPV infection. To investigate this question, material from 34 patients (15 with normal epithelium, 11 with LGSIL, 8 with HGSIL) obt...
متن کاملThe catalytic subunit of yeast telomerase.
Telomerase is an RNA-directed DNA polymerase, composed of RNA and protein subunits, that replicates the telomere ends of linear eukaryotic chromosomes. Using a genetic strategy described here, we identify the product of the EST2 gene, Est2p, as a subunit of telomerase in the yeast Saccharomyces cerevisiae. Est2p is required for enzyme catalysis, as mutations in EST2 were found to result in the ...
