Anticancer Effects of Monacolin X Against Human Liver Cancer Cell Line: Exploring the Apoptosis Using AO/EB and...

Area of Science:

• Natural Products Chemistry
• Cancer Biology
• Pharmacology

Background:

• Hepatocellular carcinoma (HCC) is a prevalent liver cancer with limited treatment options.
• Monacolin X, from Monascus ruber, shows promise for anticancer and anti-angiogenesis therapies.

Purpose of the Study:

• To evaluate the anticancer and apoptosis-inducing effects of Monacolin X on human liver cancer (HepG2) cells in vitro.
• To explore the impact of Monacolin X on intracellular reactive oxygen species (ROS) and key gene expression.

Main Methods:

• Cytotoxicity assessed via MTT assay (IC50 = 72.4 μM).
• Apoptosis induction evaluated using propidium iodide (PI) and acridine orange/ethidium bromide (AO/EB) staining.
• Intracellular ROS levels measured by DCFH-DA staining.
• Gene expression analysis (IL-6, IL-1β, TNF-α, Bax, Bcl-2) performed using qPCR.

Main Results:

• Monacolin X exhibited dose-dependent cytotoxicity against HepG2 cells.
• Apoptosis was induced, evidenced by characteristic staining and increased ROS levels.
• Downregulation of pro-inflammatory cytokines (IL-6, IL-1β, TNF-α) and modulation of apoptosis regulators (Bax, Bcl-2) were observed.

Conclusions:

• Monacolin X possesses potent anticancer activity against the HepG2 cell line.
• The compound induces apoptosis and reduces inflammation, indicating a potential therapeutic mechanism for liver cancer.
• Further research is warranted to elucidate the precise molecular pathways for clinical application in HCC.
