Project description:In order to study the physiological impact of GADD45 proteins on DNA methylation, we compared the methylation levels of Gadd45a,b,g triple knockout (TKO) and wild-type (Control) mouse embryonic stem cells (mESC) via whole genome bisulfite sequencing (WGBS).
Project description:Genome-wide methylation analysis was performed by methylated DNA immunoprecipitation (MeDIP)-CpG island (CGI) microarray analysis to identify the CpG methylation levels of Parp-1 wildtype, Parp-1 deficient or Parp inhibitor treated mouse embryonic stem cells.
Project description:We develop a single cell methylome analysis technique based on RRBS, which works robustly for mouse embryonic stem cells (mESCs), sperm, metaphase II oocytes, and zygotes.
Project description:We develop a single cell methylome analysis technique based on RRBS, which works robustly for mouse embryonic stem cells (mESCs), sperm, metaphase II oocytes, and zygotes. In total, 36 samples were analyzed, including 8 single mouse embryonic stem cells (mESCs), pooled-5, 10, 20 mESCs, bulk mESCs, 7 single sperms, 10 single pronuclei from 5 individual zygotes, 2 metaphase II oocytes, 2 the first polar bodies and 3 negative controls.
Project description:ING1b and GADD45a are nuclear proteins involved in the regulation of cell growth, apoptosis and DNA repair. We found that ING1b and GADD45a physically and functionally interact in the epigenetic regulation of specific target genes. In order to study this interaction further, we analysed the transcriptional changes in MEF cells from single and double Ing1/Gadd45 knockout mice via microarray profiling. Mouse embryonic fibroblasts (MEF cells) were isolated from embryonic day E15.5 male embryos, either wild-type (WT) or knockout for Ing1 (Ing1-/-), Gadd45a (Gadd45a-/-) or Ing1/Gadd45a (double knockout, DKO), and cultured for 3 passages. Samples were then collected in duplicates per MEF line for expression array profiling.
