Additional file 1: of Histone deacetylase inhibitors exert anti-tumor effects on human adherent and stem-like glioma cells

Figure S1. (A) Densitometry analysis of western blot shows efficacy of HDAC 1 and HDAC 2 knockdown at protein level in U-87 MG and LN18 cells after gene silencing using specific siRNAs (n = 3). The respective p values were calculated using type 2 two-tailed t test, and p < 0.05 was considered statistically significant. *p value < 0.05, **p value < 0.01. (B) Densitometry analysis of western blot for acetylated histones H3 and H4 (H3Ac, H4Ac) in HDAC 1 and HDAC 2 depleted U-87MG and LN18 cells 48 h after siRNA transfection (n = 2). (PDF 35 kb)
