Hdac1 silencer select validated sirna

SNOH-3, with purity >98%, was synthesized in Medicine Chemistry Laboratory at Shenyang Pharmaceutical University (see Figure 3a and Supplementary data). SAHA were obtained from Sigma (St. Louis, MO, USA). These agents were dissolved in DMSO to 100 mM and stored at −20 °C. Before treatment, the stock solution is diluted to different concentrations. The final concentration of DMSO in cultures is 0.1% (v/v) or less. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) and propidium idodide (PI) were purchased from Sigma. The primary antibodies against HDAC1, HDAC3, HDAC6, HDAC8, Histone 3, Histone 4, p21^WAF1/CIP1, PARP, Caspase-3, Survivin, XIAP, KLF4, VEGF, and β-actin were got from Cell Signaling Technology. The primary antibodies against CD31 were obtained from Santa Cruz Biotechnology (Santa Cruz, CA, USA). The primary antibodies against Ac-H3 and Ac-H4 were purchased from Millipore (Boston, MA, USA). The HDAC1 Silencer Select Validated siRNA was got from Life Technologies (Waltham, MA, USA).

DW22, with purity more than 98%, was synthesized in Medicine Chemistry Laboratory at Shenyang Pharmaceutical University (see Figure 2A). Bexarotene and SAHA were obtained from Sigma, USA. These agents were dissolved in DMSO to 100 mM and stored at −20°C. Before treatment, the stock solution is diluted to different concentrations. The final concentration of DMSO in cultures is 0.1% (v/v) or less. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) and Propidium idodide (PI) were purchased from Sigma, USA. The primary antibodies against RXRα, HDAC1, Histone 3, Histone 4, p21 ^WAF1/CIP1, PARP, Caspase-3, KLF4, VEGF, and β-actin were got from Cell Signaling Technology (Danvers, MA). The primary antibodies against Ki67, CD31, specific RXRα siRNA, and control siRNA duplexes were obtained from Santa Cruz Biotechnology (Santa Cruz, CA). The primary antibodies against acetylated Histone 3 and acetylated Histone 4 were purchased from Millipore, USA. The HDAC1 Silencer Select Validated siRNA was got from Life technologies, USA.
