We investigated the role of RUNX2 using three human skin fibroblast lines with RUNX2 knockdown (shRUNX2) and matched controls (shControl), treated with or without TGF-β, followed by bulk RNA sequencing. RUNX2 depletion attenuated TGF-β–induced pro-fibrotic gene programs, including extracellular matrix organization and myofibroblast differentiation. In primary fibroblasts, the small molecule F0565-0303 reduced TGF-β–induced fibrotic signatures and decreased RUNX2 expression, partially mimicking RUNX2 knockdown, while showing minimal effects under basal conditions. These results identify RUNX2 as a key driver of fibroblast activation and support its pharmacological targeting as an anti-fibrotic strategy.2026/06/10GSE330910GSM9735550GSM9735539GSM9735548GSM9735537GSM9735549GSM9735538GSM9735546GSM9735535GSM9735547GSM9735536GSM9735544GSM9735533GSM9735545GSM9735534GSM9735542GSM9735531GSM9735543GSM9735532GSM9735540GSM973554124676330910Homo sapiens
