Chromatin remodeling restrains oncogenic functions in prostate cancer.

ABSTRACT: Primary prostate cancer presents with multifocal lesions and unpredictable clinical behavior, posing significant challenges for effective prognosis. To address this, we investigate the epigenomic landscape of prostate tumor biopsies from 25 treatment-naïve male patients by analyzing chromatin compartmentalization patterns. Our analysis reveals two distinct molecular subtypes: one with a Low Degree of Decompartmentalization (LDD) and another with a High Degree of Decompartmentalization (HDD). Here we show that the HDD subgroup exhibits extensive chromatin reorganization associated with diminished oncogenic potential. This subtype shows repression of molecular pathways involved in extracellular matrix remodeling and cellular plasticity. From this distinction, we derive an 18-gene transcripti
