Project description:We report the hepatic total gene expression (starting at ZT0 and proceeding every four hours for two complete 12-hour cycles) in the liver of SRC-3 WT and KO mice.
Project description:We report the hepatic SRC-3 and XBP1s cistrome at 4-hour interval timecourse zeitgeber times (ZTs) in the liver of the C57BJ/L6 WT mice under chow and fasting conditions; we also chose liver samples at CT24, ZT0 and ZT8 for comprehensive SRC-3 and XBP1s ChIP-Seq to interrogate the genomic binding profiles of hepatic SRC-3 and XBP1s in vivo.
Project description:Time course SRC-3 ChIP-Seq and XBP1s ChIP-Seq in the C57BJ/L6 WT, SRC-3 WT versus KO, and Xbp1 WT versus LKO mice under chow and fasting conditions
Project description:Conclusions: 1. ITGα5-SRC signalling regulates the CLDN1 expression and hepatic polarity. 2. ITGα5-SRC signalling regulates the TET catelyzed DNA 5hmc/5mc level. 3. Itgα5 regulates hydroxymethylation level of genes critical for polarity in vivo. 4. Excessive deposition of ECM blocks the regulatory effect of ITGα5 on CLDN1 in vitro and in vivo.

Project description:Intracellular signaling nodes can sample multiple inputs and induce different cellular outputs. High combinatorial between their numerous potential conformational intermediaries having distinct enzymatic activities and/or repertoire of partners makes it challenging to determine their dynamic coding molecularly. We have combined protein engineering with optogenetic to investigate coding functions of specific intermediaries of the kinase Src, a representative example of versatile signaling node. Optogenetic is used to generate local flux of specific Src intermediaries, as Src dimers, into adhesion sites. Modulations of this molecular flux are sufficient to code different Src signaling pathways and Src-dependent cellular outputs implicated in migration or invasion. This response selectivity is based on the ability for each flux of Src conformational intermediary to generate distinct Src signaling waves in protein-protein interaction networks revealed by time-resolved analysis of phosphotyrosine-proteome. Thus, the pleiotropy of a signaling node is molecularly coded by modulation of its local fluxes of specific conformational intermediaries.
