Project description:adenovirus mediated overexpression of wild-type CtBP2 and Rossmann fold mutant CtBP2 along with control GUS in dietary induced obese mice
Project description:Using an RNA interference-based genetic screen in mouse F9 cells we identify the transcriptional corepressor CTBP2 as a coactivator critically required for retinoic acid (RA)-induced transcription. Here we perfom a whole genome transcriptome analysis in F9 cells expressing shRNA for Ctbp2 and Rxr in the absence or presence of retinoic acid (RA). A total of 2,754 genes were found to be upregulated (>2 fold) and 1518 genes were downregulated (>2 fold) in response to RA treatment in the control cells. We find that around 52% and 55% of upregulated genes are dependent on Ctbp2 and Rxr for activation respectively suggesting that Ctbp2 is a coactivator of RA signaling.

Project description:Profiling of epigenetic and transcriptomic landscapes in normal mouse liver, phenobarbital exposed mouse livers and mouse liver tumours
Project description:To identify oligomerization dependent interactors of C-terminal binding protein 2 (CTBP2), we stably expressed CTBP2 wild type or a monomeric mutant (CTBP2 mono: CTBP2 C140Y, N144R, R147E, L156W) in Ctbp1-/-, Ctbp2-/- J774.1 cells and profiled their genome-wide interactome in LPS conditions after 3 h of stimulation. Differential profiling of CTBP2’s wild type and monomeric interactome shows oligomer-specific interactions with multiple repressors including KDM1A and the NuRD complex. Conversely, monomers retain the ability to interact with AP-1 and RNA polymerase II.
