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. This evidence concerns the gene HIF1A and gastric cancer.
