In vitro E3 ubiquitin ligase activityassays reveal that PRT4165 inhibits both RNF

4、2 and RING 1A, but not RNF8 nor RNF168. In the presence ofPRT4165, H2A ubiquitylation could be completely inhibited regardless of whether RING1 or RNF2contributes the E3 ubiquitin ligase activity. Treatment of cells for 60 min with 50 M PRT4165 results in adramatic reduction in total ubiquitylated h

5、istone H2A. It is also found that longer exposure of the cells with thePRT4165 (30 and 60 min) leads to increased levels of -H2AX in unirradiated cells. PRT4165 inhibits double-strand break (DSB) repair at the 8-h time point compare with mock treated cells. Cells treated with increasingconcentration

6、s of PRT4165 show increasing numbers of cells in G2/M 1.PROTOCOLCell Assay 1 Cells are treated with different concentrations of the PRT4165 60 min prior to irradiation (2 Gy). The cells areharvested 2 h after IR. The cells are washed with PBS twice and then fixed with 1% paraformaldehyde at37C for 1

7、0 min. After cooling on ice for 1 min, the cells are permeabilized with 90% methanol and stored at -20C overnight. Fixed cells are washed with PBS twice and blocked with FACS incubation buffer (0.5% BSAin PBS) for 10 min. The cells are then stained with anti-phosphohistone H3 (serine 10) antibody at
