Next, to directly show a functional link between the expression of GPX7 and the acetylation of histones, we analyzed the distributions of active chromatin marks, marked by histone 3 lysine 9 and/or lysine 27 acetylation (H3K9ac or H3K27ac, respectively), mapped by ChIP-Seq using data from the ENCODE Project in UCSC Genome Browser database in different human glioma models. The gene discussed is GPX7; the disease is glioma.
