iMEF SDHC-loss RRBS time course

We have developed a tet-inducible immortalized mouse embryonic fibroblast (iMEF) cell culture model of SDH-loss paraganglioma/pheochromocytoma in which silencing gene rearrangement of the Sdhc floxed allele is driven by doxycycline-dependent expression of cre-recombinase from a tet-inducible promoter (R26M2rtTA/+;TetOcre;Sdhcfl/fl). Using this model and an isogenic Sdhc wt control line (R26M2rtTA/+;TetOcre;Sdhcfl/wt), we have characterized the time-course of Sdhc gene rearrangement, protein loss, and succinate accumulation following induction with doxycycline. Using reduced representation bisulfite sequencing (RRBS), we have quantified changes in the genome-wide distribution of cytosine/5'-methyl-cytosine due to succinate accumulation using our Sdhc -/- cell line. Through a time-course experimental design, we have grown R26M2rtTA/+;TetOcre;Sdhcfl/fl (experimental) and R26M2rtTA/+;TetOcre;Sdhcfl/wt (control) iMEFs in standard DMEM media containing 10% FBS and quantified DNA methylation changes in these cells as a function of time after triggering SDHC gene rearrangement via doxycycline exposure. Overall design: Included in this dataset are single replicate RRBS time course data for experimental (R26M2rtTA/+;TetOcre;Sdhcfl/fl) and control (R26M2rtTA/+;TetOcre;Sdhcfl/wt) cell lines at days 0, 5, 9, 12,16, and 20 after induction with doxycycline.
