Increased Persistence of gamma-H2AX as a Novel Approach to High Content Screening for Small Molecule Radiosensitizers

ABSTRACT: This study is about high content screening small molecule compound as radiosensitizer. Two compounds were got finally from a chemical bank. Our data indicate cancer cell lines became more sensitive to radiation after treatment with both two compounds respectively. In order to know the mechanism, microarray was performed to try to find the target genes of one compound. DU145 cells were treated with MS0019266 (5 umol/L) for 8 hours and total RNA was extracted from treated and untreated cells respectively. Synthesis of cDNA from total RNA and hybridization/scanning of microarrays were performed with Affymetrix GeneST1.0 array as described in the GeneChip manual. The raw intensity data were extracted from the GeneChip using Gene Expression Console ( Affymetrix Inc.) and normalized across the
