SRA

To investigate the effects of TBI on affecting the DNA methylation in the hippocampus of male SD rats by sequencing the methylome (RRBS). Overall design: Male Sprague–Dawley (SD) rats weighing between 200 and 240 g were housed in cages and maintained in environmentally-controlled rooms (22–24C) with a 12-h light/dark cycle. After acclimatization for 1 week on standard rat chow, the rats were subjected to TBI by fluid percussion injury (FPI) or sham surgery. At 1 week post-surgery the rats were tested for learning abilities, and then were sacrificed by decapitation. The fresh tissues including the hippocampus were dissected out, flash frozen, and stored at -70°C for later transcriptome and DNA methylome sequencing experiments. All experiments were performed in accordance with the United States National Institutes of Health Guide for the Care and Use of Laboratory Animals and were approved by the University of California at Los Angeles Chancellor’s Animal Research Committee.
