This included downregulation of AP-1 transcription factors (FOS, JUND, JUNB), suppression of oxidative phosphorylation and steroidogenic pathways, and increased expression of pro-apoptotic genes. These findings support entinostat's potential to reverse high-risk epigenetic programs in pACT and highlight HDAC inhibition as a promising therapeutic avenue, particularly when combined with established treatments.2026/08/12GSE336546GSM9837159GSM9837158GSM9837160GSM9837157GSM9837156GSM983715534284336546Homo sapiens
