Senataxin Mutation Reveals How R-Loops Promote Transcription by Blocking DNA Methylation at Gene Pro
Dr. Grunseich and colleagues found that patients’ cells with a senataxin mutation have fewer R-loops. They showed that having fewer R-loops decreases BAMBI expression and consequently increases TGFb signaling. Nascent RNAs form Rloops in gene promoters that facilitate transcription by disrupting DNA methylation in more than 1,200 human genes.
