mRNA expression analysis of radiation-induced skin fibrosis of rats

This study aims to compared mRNA expression between radiation-induced fibrotic skin and adjacent normal tissues of rats by RNA-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 mRNA expression analysis.
