Fig. 4From: SIRT1 affects DNA methylation of polycomb group protein target genes, a hotspot of the epigenetic shift observed in ageingMeasurement of EZH2 protein under conditions of SIRT1 knockdown. SIRT1 knockdown in Caco-2 cells was achieved using two different siRNAs and protein was analysed by Western blotting using anti-EZH2 antibody (a) or anti-SIRT1 antibody (to confirm efficacy of knockdown) (b). Blots were probed with anti-α-tubulin antibody to confirm equal protein loading and transfer. Approximately 10 μg of protein was loaded in each lane. Three biological replicates are presented for each condition. Approximate molecular weights are indicatedBack to article page
