RASSF4 and sarcoma: It subsequently explores core signaling pathways regulated by RASSF4 in the context of cell cycle regulation, apoptosis, and metastasis, notably the rat sarcoma/mitogen-activated protein kinase (RAS/MAPK) and Hippo–yes-associated protein (Hippo-YAP) pathways, while also evaluating the potential of RASSF4 as a diagnostic and prognostic biomarker alongside its utility as a therapeutic target.
