Ganoderic acid A inhibits proliferation and invasion, and promotes apoptosis in human hepatocellular carcinoma cells

Area of Science:

• Pharmacology
• Oncology
• Molecular Biology

Background:

• Ganoderic acid A (GA-A), a triterpenoid, exhibits anticancer properties in various cancers.
• The therapeutic potential of GA-A in human hepatocellular carcinoma (HCC) requires further investigation.

Purpose of the Study:

• To investigate the in vitro effects of GA-A on human HCC cell lines.
• To determine GA-A's impact on HCC cell proliferation, cell cycle, apoptosis, migration, and invasion.

Main Methods:

• Human HCC cell lines (HepG2, SMMC7721) were treated with varying GA-A concentrations.
• Cell proliferation, cell cycle, apoptosis, migration, and invasion were assessed using CCK-8, flow cytometry, and Transwell assays.
• Apoptosis-associated protein expression was analyzed via Western blot.

Main Results:

• GA-A significantly inhibited HCC cell proliferation in a dose-dependent manner.
• GA-A induced G0/G1 cell cycle arrest and promoted apoptosis in HCC cells.
• GA-A suppressed HCC cell migration and invasion, decreasing cyclin D1 and increasing p21 and cleaved caspase-3 expression.

Conclusions:

• GA-A demonstrates potent inhibitory effects on human HCC cell proliferation, migration, and invasion in vitro.
• GA-A's mechanisms involve cell cycle arrest and induction of apoptosis.
• GA-A represents a potential natural therapeutic agent for HCC treatment.
