concentrations of compounds and vehicle. The cells incubated with
different treatments were washed with 1× PBS and harvested in
1× laemmli sample buffer. The cell lysate total protein relative
concentration estimated with amido black method and an equal amount
of protein was loaded onto 12% sodium dodecyl sulfate-polyacrylamide
gel electrophoresis gel. Blocking was done for 1 h at room temperature,
followed by incubation with primary antibodies H3 acetyl (1:1000),
H4 acetyl (1:2000), and H3 PAN (1:3000) overnight at 4 °C. The
blots were washed with 1× PBST, and incubation in secondary antibody
anti-rabbit (1:5000) was done at room temperature for 1 h. The blots
were again washed with 1× PBST and then developed with the Bio-Rad
ChemiDoc instrument using WesternBright ECL solution (advansta). The
band intensities of Western blots were measured using ImageJ software.
