Ageing is a fundamental, unsolved mystery in biology. DAF-16, a FOXO-family transcription factor, influences the rate of ageing of Caenorhabditis elegans in response to insulin/insulin-like growth factor 1 (IGF-I) signalling. Using DNA microarray analysis, we have found that DAF-16 affects expression of a set of genes during early adulthood, the time at which this pathway is known to control ageing. Here we find that many of these genes influence the ageing process. The insulin/IGF-I pathway fun ...[more]

RNAi knock down of daf-2, daf-3, daf-16 in C. elegans over 0-48 hours

Project description:Comparison of sterile worms grown on Control Vector, daf-2 RNAi, and daf-2 + daf-16 RNAi. Synchronized fer-15(b26); fem-1(hc17) animals were grown on RNAi bacteria at 25ºC, induced with IPTG on Day 1 of adulthood, and collected from 0-48 hours (10 time points) and 0-196 hours (10 time points); RNAi bacteria was supplemented as necessary for later time points. Worms were floated off lawns with M9 buffer, centrifuged, and washed again in M9. The pelleted worms were dissolved in Trizol (Gibco) and frozen in liquid nitrogen.Time courses were compared with mixed references (collected from 1/2 of each of the time course samples)

Defining changes in the total levels of proteins during aging of C. elegans

Project description:We performed label-free proteomics in C. elegans to define and quantify changes in the ubiquitinated (Ub)-proteome during the aging process. More specifically, we compared wild-type worms at the first day of adulthood with young (day 5), mid-age (day 10) and aged adults (day 15). Moreover, we assessed protein levels of age-matched long-lived genetic models of dietary restriction (eat-2(ad1116)) and reduced insulin/IGF-1 signaling (daf-2(e1370)).

Defining changes in the steady-state levels of ubiquitinated peptides in aging and longevity

Project description:We performed diGLY enrichment followed by label-free proteomics in C. elegans to define and quantify changes in the ubiquitinated (Ub)-proteome during the aging process. More specifically, we compared wild-type worms at the first day of adulthood with young (day 5), mid-age (day 10) and aged adults (day 15). Moreover, we assessed the Ub-modified proteome of age-matched long-lived genetic models of dietary restriction (eat-2(ad1116)) and reduced reduced insulin/IGF-1 signaling (daf-2(e1370)).

wt vs daf-2 C. elegans protein turnover

Project description:Most aging hypotheses revolve around the accumulation of some sort of damage resulting in gradual physiological decline and ultimately death. Avoiding protein damage accumulation by enhanced turnover should slow down the aging process and extend lifespan. However, lowering translational efficiency extends rather than shortens lifespan in C. elegans. We studied turnover of individual proteins in the conserved Insulin/Insulin-like Growth Factor (IGF-1) receptor mutant daf-2 by combining Stable Isotope Labeling by Nitrogen-15 in Caenorhabditis elegans and LC-MS/MS. Intriguingly, the majority of proteins displayed prolonged half-lives in daf-2, while others remained unchanged, signifying that longevity is not supported by high protein turnover. This slow-down of protein turnover was most prominent for components of the translation machinery and mitochondria. In contrast, the high turnover of lysosomal hydrolases and very low turnover of cytoskeletal proteins remained largely unchanged in daf-2. The slow-down of protein dynamics and decreased abundance of the translational machinery may point at the importance of anabolic attenuation in lifespan extension as suggested by the hyperfunction theory.
