Endogenous DAF-16 genome-wide recruitment under low Insulin signaling condition in Caenorhabditis elegans

ABSTRACT: 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

Endogenous DAF-16 genome-wide recruitment under low Insulin signalling condition in Caenorhabditis elegans

Project description:In order to understand the complexity of gene regulation downstream of IIS, we did RNA-seq in mixed culture in wild-type, daf-2(e1370), daf-16(mgDf50);daf-2(e1370) and daf-2(e1370);daf-12(m20 and correlated it with ChIP-seq data

RNA sequencing analysis of DAF-16 target gene expression when math-33 function is genetically inactivated

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. 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.

C. elegans microarrays: daf-2(-) vs. daf-2(-) xbp-1(-)

Project description:Transcriptional profiling of day 1 animals comparing untreated daf-2(-) animals and daf-2(-) xbp-1(-) animals. Goal was to identify genes whose expression in daf-2 mutants is dependent (directly or indirectly) on xbp-1. Two-condition experiment, daf-2(-) animals and daf-2(-) xbp-1(-) animals. 4 Biological replicates in daf-2(e1370) background: 4 sets of daf-2(e1370) animals and their matching daf-2(e1370) xbp-1(zc12) animals. 4 Biological replicates in daf-2(e1368) background: 4 sets of daf-2(e1368) animals and their matching daf-2(e1368) xbp-1(zc12) animals.
