DNA methylation analysis of radiation-induced skin fibrosis of rats
This study aims to compared the genome-wide DNA methylation status in radiation-induced fibrotic skin and adjacent normal tissues of rats by methylated DNA immunoprecipitation sequencing (MeDIP-Seq). Male Sprague-Dawley (SD) rats (4 weeks old) were irradiated with a single 45-Gy dose of irradiation was administered to the treatment area at a rate of 750 cGy/min using a 6-MeV electron beam accelerator (Clinac 2100EX, Varian Medical Systems, Inc., CA). Skin tissues from nonirradated skin areas and irradietd areas were collected and subjected to DNA methylation analysis by MeDIP. Overall design: Male Sprague-Dawley (SD) rats (4 weeks old) were irradiated with a single 45-Gy dose of irradiation was administered to the treatment area at a rate of 750 cGy/min using a 6-MeV electron beam accelerator (Clinac 2100EX, Varian Medical Systems, Inc., CA). Skin tissues from nonirradated skin areas (NC) and irradietd areas were collected and subjected to DNA methylation analysis by MeDIP.
