Cell reports yeast aging
WebMay 25, 2007 · Introduction. The budding yeast Saccharomyces cerevisiae is a widely used model of cellular and organismal aging [1–4].The first studies of yeast aging were published over 50 years ago, in which yeast cells were shown to have a finite replicative capacity [].Replicative life span was thus defined as the number of daughter cells … WebSep 2, 1997 · We wished to test the effects of telomere shortening on the lifespan of yeast mother cells, even though yeast telomeres do not shorten in normal aging (24, 29). Thus, we overexpressed the dominant truncated allele of TLC1 ( tTLC1 ), which was shown to result in telomeres adopting a shorter steady-state length (ref. 9 ; Fig. 1 A , lane 3).
