(Submitter supplied) Telomerase, the essential enzyme that maintains telomere length, contains two core components, TERT and TR. While early studies in yeast and mouse both indicated that loss of telomerase leads to phenotypes that arise after an increased number of generations, due to telomere shortening, recent studies claim additional roles for telomerase components in transcription and the response to DNA damage. To test these telomere length maintenance-independent roles of telomerase components, we examined first generation mTR-/- and mTERT-/- mice with long telomeres. more...

(Submitter supplied) Recent studies suggest that telomerase promotes cell growth by mechanisms that extend beyond the rescue of critically short telomeres. The in vitro model of mTert overexpressing MEFs recapitulates fundamental aspects of the growth-promoting effects of mTert in vivo. First, in Terc-proficient cells, mTert overexpression favors escape from replicative senescence and enhances anchorage-independent growth in response to oncogenic stress, which fits well with previous data showing that mTert overexpression promotes tumor formation. more...

(Submitter supplied) Telomeres shorten with each round of cell division, and the expression of telomerase serves to lengthen telomeres. In the absence of telomerase, telomeres shorten to the point of uncapping and causes defects in tissues with high turnover, including the intestinal epithelium. In mice lacking telomerase (e.g. mTR-/-), telomeres critically shorten after several generations of telomerase deficiency, with pronounced defects in their intestine. more...

(Submitter supplied) Lung diseases develop when telomeres are shortened beyond a critical point. We have constructed a mouse model in which the catalytic subunit of telomerase (mTert), or its catalytically inactive form (mTertCI), is expressed from the p21Cdkn1a promoter. We found that this particular expression of mTert reduces senescence of endothelial cells (EC) in lungs of aged mice, as well as emphysema and pulmonary perivascular fibrosis. more...
