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 RNA-seq, we have quantified changes in gene expression 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 transcriptional changes in these cells as a function of time after triggering SDHC gene rearrangement via doxycycline exposure.
