Hepatocellular carcinoma (HCC) is a highly aggressive malignancy characterized by rapid progression, therapeutic resistance, and poor prognosis. This project aims to investigate the molecular mechanisms underlying HCC development and progression, with a particular focus on signaling pathways that regulate tumor growth, invasion, and treatment response. By integrating transcriptomic profiling with functional and prognostic analyses, the study seeks to identify key regulatory factors associated with disease progression and therapeutic efficacy. The findings are expected to provide mechanistic insights into HCC pathogenesis and offer a scientific basis for evaluating potential therapeutic strategies and prognostic biomarkers.
