Dietary terpenoids and prostate cancer chemoprevention

Area of Science:

• * Oncology
• * Pharmacology
• * Nutritional Science

Background:

• * Cancer chemoprevention using phytochemicals is a promising strategy for cancer control.
• * Phytochemicals, including terpenoids and phenolic compounds from various plant sources, demonstrate efficacy in suppressing experimental carcinogenesis.
• * Prostate cancer's high prevalence and long latency period offer opportunities for chemopreventive interventions.

Purpose of the Study:

• * To review naturally occurring dietary terpenoids as potential agents for prostate cancer chemoprevention.
• * To discuss the classes and sources of these terpenoids.
• * To highlight their relevance in different stages of prostate cancer progression.

Main Methods:

• * Review of scientific literature on phytochemicals, terpenoids, and prostate cancer chemoprevention.
• * Analysis of mechanisms underlying chemopreventive effects, including antioxidant, anti-inflammatory, and cell cycle modulation.
• * Consideration of factors for effective chemopreventive interventions in specific populations.

Main Results:

• * Terpenoids and other phenolic compounds exhibit chemopreventive properties in pre-clinical models.
• * Mechanisms involve antioxidant, anti-inflammatory, immune-enhancing, and hormone modulation effects.
• * Modulation of drug metabolizing enzymes, cell cycle, differentiation, apoptosis, proliferation, and angiogenesis are key pathways.

Conclusions:

• * Naturally occurring dietary terpenoids are valuable agents for prostate cancer chemoprevention.
• * Understanding their mechanisms and identifying suitable target populations are crucial for future interventions.
• * Further research into specific terpenoid classes and sources can optimize their application.
