Figure 3From: Radiosensitization of colorectal carcinoma cell lines by histone deacetylase inhibitionHistone acetylation by TSA. The HCT116 and SW620 cell lines were treated with TSA in increasing concentrations, and protein extracts prepared after 12 and 24 hours of incubation were analyzed by Western blot immunostaining with antibodies against acetylated histones H3 (acetyl-H3) and H4 (acetyl-H4). α-tubulin was measured as protein loading control.Back to article page
