Functional in vitro assays further revealed that silencing ARHGEF7‐AS2 significantly promotes both proliferation and migration of HCC cells, suggesting that ARHGEF7‐AS2 may act as a tumor suppressor. These findings indicate that ARHGEF7‐AS2 not only plays an important regulatory role within the ceRNA network but also holds promise as an independent prognostic biomarker for HCC."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n "}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Qi-Feng Chen, Tao Huang, Qi-Jiao Si-Tu, et al.
