Anticancer Properties of Tangeretin
Research Guide

What is Anticancer Properties of Tangeretin?

Tangeretin is a methoxylated flavone from citrus fruits exhibiting anticancer effects through G1 cell cycle arrest, anti-proliferative activity, and inhibition of cancer cell invasion without inducing apoptosis.

Tangeretin, abundant in tangerine peels, targets human breast and colon cancer cells primarily via G1 phase arrest (Morley et al., 2007, 233 citations). Thomas Walle (2007, 284 citations) positions methoxylated flavones like tangeretin as superior chemopreventive agents over other flavonoids. Approximately 10 papers from the provided list directly address its mechanisms, with studies spanning 2007-2020.

Key Challenges

Why It Matters

Tangeretin's ability to arrest cell cycle in breast and colon cancer cells supports flavonoid-based dietary chemoprevention (Morley et al., 2007). It modulates inflammatory pathways linked to cancer progression, offering potential for reducing tumor metastasis via plant-derived interventions (Prasad et al., 2010). Meiyanto et al. (2012) highlight its role in targeted therapy, aiding development of natural product drugs to lower cancer incidence through citrus consumption.

Key Research Challenges

Low Oral Bioavailability

Tangeretin's poor absorption limits systemic anticancer efficacy despite strong in vitro effects (Walle, 2007). Enhancing delivery via nanoformulations or synergists remains underexplored in citrus flavones. No provided papers quantify human bioavailability improvements.

Mechanisms Beyond G1 Arrest

While G1 arrest is confirmed in breast/colon lines, apoptosis induction and tumor microenvironment effects need deeper elucidation (Morley et al., 2007). In vivo metastasis inhibition requires validation beyond in vitro invasion assays (Weng and Yen, 2012). Clinical translation gaps persist.

Dose-Response in Humans

Optimal dosing for chemoprevention is unclear, as studies focus on cell lines without human trials (Meiyanto et al., 2012). Variability in citrus content complicates dietary recommendations (Lv et al., 2015). Toxicity at high doses unaddressed.
