Figure 5: dUTX is recruited to the promoters of apoptosis and Atg genes.

(a,b) The occupancy of dUTX on the promoter regions of apoptosis and Atg genes was detected by chromatin immunoprecipitation (ChIP). SL2 cells overexpressing HA-dUTX were chromatin-immunoprecipitated with anti-HA and anti-GFP (IgG control) antibodies following ecdysone treatment. qPCR was used to assess the binding to the promoters of dark, dronc, drice and rpr (a) and Atg1, Atg2, Atg3, Atg4, Atg5, Atg6, Atg7, Atg8a, Atg9, Atg12 and Atg18 (b), expressed relative to the internal control gene Gapdh. Results are shown as the fold enrichment of % input compared with IgG control. (c) The abundance of H3K27me3 on the promoters of apoptosis and autophagy genes detected by ChIP. SL2 cells knocked down for dUTX were chromatin-immunoprecipitated with anti-H3K27me3 and anti-GFP (IgG control) antibodies following ecdysone treatment. Results are shown as the fold enrichment of % input compared with RNAi control. (d) The occupancy of EcR on the promoter regions of dark, dronc and Atg1 by ChIP expressed relative to the internal control gene rp49. Chromatin was immunoprecipitated with anti-EcR-B1 and anti-GFP (IgG control) antibodies from SL2 cell following ecdysone treatment. Results are shown as the fold enrichment of % input compared with IgG control. Data in all panels are expressed as means from three independent experiments, with error bars representing s.e.m. *P<0.05 (Student’s t-test).
