Project description:To identify DAF-16-dependent transcriptional alterations that occur in a long-lived C. elegans strain, we used cDNA microarrays and genomic analysis to identify putative direct and indirect DAF-16 transcriptional target genes. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Keywords: Logical Set

Project description:In this study we have investigated the effect of loss of math-33 activity on DAF-16-mediated target gene regulation in C. elegans under conditions of reduced Insulin/IGF-1 signaling (IIS). Using whole nematode RNA sequencing experiments we found that the daf-2(e1370)-mediated induction and repression of DAF-16 target genes was decreased in daf-2(e1370); math-33(tm3561) mutant animals. Our data suggest that the downregulation of endogenous DAF-16 isoforms in the absence of a functional MATH-33 severely affects the global expression of DAF-16 targets when IIS activity is reduced. Therefore, MATH-33 is essential for DAF-16-mediated target gene activation and repression in the context of IIS.

Project description:In order to understand the complexity of gene regulation downstream of IIS, we used anti-DAF-16 antibody, we report the first genome-wide ChIP-sequencing study of endogenous DAF-16 recruitment in daf-2(e1370). We also report the average bin-wise normalized read count of ZFP-1 and DAF-16 on DAF-16 summits

Project description:Dietary restriction (DR) is the most effective and reproducible intervention to extend lifespan in divergent species1. In mammals, two regimens of DR, intermittent fasting (IF) and caloric restriction (CR), have proven to extend lifespan and reduce the incidence of age-related disorders2. An important characteristic of IF is that it can increase lifespan, even when there is little or no overall decrease in calorie intake2. The molecular mechanisms underlying IF-induced longevity, however, remain largely unknown. Here we establish an IF regimen that effectively extends the lifespan of Caenorhabditis elegans, and show that a nutrient-related signalling molecule, the low molecular weight GTPase Cel-Rheb, has a dual role in lifespan regulation; Cel-Rheb is required for the IF-induced longevity, whereas inhibition of Cel-Rheb mimics the CR effects. We also show that Cel-Rheb exerts its effects in part via the insulin/IGF-like signalling effector DAF-16 in IF, and that Cel-Rheb is required for fasting-induced nuclear translocation of DAF-16. We find that HSP-12.6, a DAF-16 target, functions to mediate the IF-induced longevity. Furthermore, our analyses demonstrate that most of fasting-induced upregulated genes require Cel-Rheb function for their induction, and that Cel-Rheb/Cel-TOR signalling is required for the fasting-induced downregulation of an insulin-like peptide, INS-7. These findings identify the essential role of signalling via Cel-Rheb in IF-induced longevity and gene expression changes, and suggest a molecular link between the IF-induced longevity and the insulin/IGF-like signalling pathway.

DAF-16 mediated target gene regulation was analyzed in daf-2(e1370) nematodes and compared to daf-2(e1370); math-33(tm3561) mutant animals. daf-16(mu86); daf-2(e1370); N2 (wild type) and math-33(tm3561) single mutant animals were used as controls.
