PCAT6 and gastric cancer: Hypoxic lncRNA‐PMAN strongly suppresses ferroptosis by promoting the cytoplasmic translocation of ELAVL1 in peritoneal dissemination from gastric cancer.[35] HIF‐1α‐induced lncRNA DACT3‐AS1 facilitates HCC metastasis via FOXA3 deacetylation.[36] Consistent with this fact, we found that hypoxia‐regulated PCAT6 is crucial for BCSCs stemness maintenance and chemoresistance in vitro and in vivo.
