Key lncRNAs, pathways, and functions in HCC.
| LncRNAs | Pathway/Process | Function | Clinical relevance | Reference |
|---|---|---|---|---|
| LINC00958 | Lipid metabolism | Promotes lipogenesis and tumor progression | Upregulated in HCC, associated with tumor progression, metastasis, and poor prognosis | [121] |
| PAPAS | miR-188-5p axis | Promotes cell proliferation/tumor progression | Involved in tumour progression; possible function in transcriptional dysregulation in cancer | [122] |
| TUG1 | miR-137/AKT2 axis | Promotes cell proliferation and invasion | High expression correlates with advanced stage, poor prognosis, and therapy resistance | [123] |
| LINC01503 | MAPK/ERK pathway | Activates MAPK/ERK signaling, promoting tumor growth and metastasis | Associated with aggressive tumor behavior and unfavorable prognosis | [124] |
| HULC | NF-κB pathway | Modulates inflammation and immune responses, contributing to HCC progression | Poor prognosis, early diagnosis | [125] |
| TINCR | miR-375/ATG7 axis | Regulates cell proliferation and invasion | Overexpression is associated with tumour advancement and reduced overall survival | [126] |
| lnc-PIK3R1 | PI3K/AKT pathway | Inhibits tumor progression by modulating the PI3K/AKT pathway | Dysregulation associated with HCC development and pathway-driven oncogenesis | [127] |
| LncRNA NORAD | miR-211-5p/FOXD1/VEGF-A axis | Promotes proliferation, migration, and angiogenesis | Overexpression correlates with advanced stage and poor prognosis | [128] |
| CASC2 | miR-155/SOCS1 axis | Regulates cell proliferation and invasion | Reduced expression in HCC is linked to a poorer prognosis | [129] |
| USP27X-AS1 | USP7-mediated AKT stabilisation | Promotes hepatocellular carcinoma progression | Overexpression predicts aggressive phenotype and poor clinical outcome | [130] |
| MALAT1 | MAPK/ERK, apoptosis, EMT | EMT, apoptosis, metastasis | Post-transplant recurrence, survival | [113] |
| NEAT1 | IL-6/STAT3 signaling | Invasion, ferroptosis, metastasis, proliferation, drug resistance | Drug resistance, poor outcome | [131] |
