In LSCC, LINC00886 is significantly downregulated due to aberrant methylation of its promoter region, and this epigenetic silencing is associated with higher pathological grade. Restoration of LINC00886 expression leads to dramatic inhibition of cell proliferation, migration, and invasion in vitro as well as suppressed tumor growth in vivo. The antitumor effect of LINC00886 appears to be linked with its regulation of key oncogenic signaling pathways such as VEGFA/PI3K/AKT and the epithelial-mesenchymal transition (EMT) process."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n "}]}, {"type": "t", "text": "\n "}, {"type": "p", "children": [{"type": "t", "text": "\n While the direct role of LINC00886 was specifically characterized in LSCC, the broader context of long noncoding RNAs (lncRNAs) in cancer is further supported by studies in non‐small cell lung cancer and breast cancer.
