Application of Quercetin in the Treatment of Gastrointestinal Cancers

Area of Science:

• Oncology
• Natural Products Chemistry
• Molecular Biology

Background:

• Cellular signaling pathways regulate critical cell functions like proliferation and apoptosis.
• Dysregulation of these pathways is implicated in cancer initiation and progression.
• Natural products are increasingly explored for their therapeutic potential in cancer treatment.

Purpose of the Study:

• To summarize the therapeutic effects of quercetin in gastrointestinal cancers.
• To highlight quercetin's mechanisms of action against tumor progression.
• To review quercetin's role in pancreatic, gastric, colorectal, esophageal, hepatocellular, and oral cancers.

Main Methods:

• Literature review of studies on quercetin and gastrointestinal cancers.
• Analysis of quercetin's mechanisms, including cell cycle arrest and apoptosis induction.
• Examination of quercetin's antioxidant properties in cancer models.

Main Results:

• Quercetin demonstrates significant inhibitory effects on tumor progression in various gastrointestinal cancers.
• Key mechanisms include the induction of cell cycle arrest and apoptosis.
• Antioxidant properties of quercetin contribute to its anti-cancer effects.

Conclusions:

• Quercetin is a promising natural compound for the treatment of gastrointestinal cancers.
• Its multifaceted mechanisms of action warrant further investigation for clinical application.
• Dietary intake of quercetin-rich foods may offer protective benefits against these cancers.
