In this work, EpCAM‐positive serum exosomes were shown to promote lung cancer progression in vitro and in vivo, and two specific lncRNAs—RP11-77G23.5 and PHEX-AS1—were found to be significantly elevated in lung cancer patients. RP11-77G23.5 demonstrated the potential to distinguish between lung adenocarcinoma (LUAC) and lung squamous cell carcinoma (LUSC), whereas PHEX-AS1 levels were associated with tumor stage and metastasis, highlighting their roles in cancer subtyping and progression."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIt should be noted that the abstract does not mention PTCHD1-AS or provide any data regarding its function.
