Abstract:
HCC is one of the deadliest malignancies with a rising global occurrence and poor prognosis. Metastasis and invasion are essential processes in the HCC progression, and have a profound bearing on clinical outcome. This review explores the key signalling pathways involved in HCC metastasis and invasion, focusing on their molecular mechanisms, crosstalk, and therapeutic implications. Alongside the discussion of the Wnt/β-catenin, TGF-β, PI3K/AKT/mTOR, MAPK/ERK, HGF/c-MET, Notch and Hippo-YAP/TAZ pathways, are known to contribute to promoting aggressive HCC behaviour. Stromal interactions, extracellular matrix remodelling, hypoxia and angiogenesis as well as the tumour microenvironment are also highlighted. These pathways are subject to current therapeutic treatments in the form of tyrosine kinase inhibitors and monoclonal antibodies, and research prospective of the Wnt/β-catenin blocker, TGF-β inhibitors, etc. The variations in tumours and resistance patterns to treatment and their existing problems in treating HCC are addressed. The review evaluates new therapeutic targets offering a foundation for further research and clinical advancements in this challenging field.

Interactions Between Signaling Pathways
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
