Figure 1. SIRT1 shows increased expression and associates with DNMT3B during stress condition.
The expression of γH2AX (A), SIRT1 (B) and H4K16ac (C) were evaluated by western blot in adhered (ma) and deadhered (D24h) melan-a melanocytes. The expression of β-ACTIN or ERK was used as endogenous control. The interaction between SIRT1 and DNMT3B (D) was determined by co-immunoprecipitation in adherent (ma) and deadhered (D24h) melanocytes. Total: Total protein extract used in IP assay; IP: immunoprecipitated protein fraction.
