查询词典 yellow arsenic

Reverse-transcription PCR assays were used to detect the mRNA expression level of related regulatory genes such as p15, p16, p21, p27, p57, surviving, cyclin B, cdc2 and chk1, and Western blot assay to detect the level of protein expression and phosphated change such as survivin, cdc2 and chk1. Results:(1) K562 cell arrested on G2/M phase were obviously increased after co-cultured with 2 to 10μmol/L Arsenic trioxide for 24 hours. The ratios of control group, 2μmol/L, 5μmol/L and 10μmol/L groups were 22.6±3.4%, 27.2±2.3%, 43.8±4.5% and 36.7±4.1%, respectively.
