In addition, SChLAP1 regulates microRNA networks, for instance by repressing miR‑198 to influence MAPK1 signaling and, via direct interaction with epigenetic modifiers like EZH2, by promoting H3K27me3-mediated silencing of tumor-suppressive miRNAs. These multifaceted interactions enhance cancer cell proliferation, migration, and invasiveness."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "5", "end_ref": "7"}]}, {"type": "t", "text": ""}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nBeyond prostate cancer, SChLAP1 exhibits oncogenic activities in several other malignancies.
