RFX6 and neoplasm: Lentivirus‐mediated RFX6 knockdown in 22Rv1 cells resulted in a notable decrease in cell growth, viability, colony formation, and migratory and invasive capabilities compared to control shRNA‐treated cells (Extended Data Figure S2b–e, Supporting Information), consistent with our previous findings using siRNA‐mediated RFX6 tumor cell biology assays.[33]
