IMEF SDHC-loss stable line histone acetyltransferase inhibitor ATAC-seq

ABSTRACT: We have developed a tet-inducible SV-40 large T antigen-expressing lentivirus-immortalized mouse embryonic fibroblast (iMEF) cell culture model of mitochondrial electron transport chain (ETC) dysfunction involving complex II (succinate dehydrogenase; SDH) 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). Following doxycycline induction, dilutional subcloning was employed to obtain stable Sdhc -/- (SDHC KO) cell lines. Sdhc gene rearrangement status for each clonally-derived cell line was confirmed by PCR. Cell lines were grown in standard DMEM containing penicillin/streptomycin antibiotics (0.5 mg/mL), non-essential amino acids (100 micromolar each of glycine, alanine, asparagine, aspartic acid, glutamic acid, proline, and serine), sodium pyruvate (1 mM), and HEPES buffer (10 mM) at 21% O2 and 5% CO2. Following cell line derivation and verification of Sdhc genetic status, cells were treated with histone acetyltransferase inhibitors C646 (10 µM) and MB-3 (100 µM) or vehicle for 3 days. Accessible chromatin regions were subsequently interrogated by ATAC-seq.
