Saffron anti-metastatic properties, ancient spice novel application

Area of Science:

• Pharmacology and Phytochemistry
• Cancer Biology and Therapeutics

Background:

• Saffron (Crocus sativus L.) has a long history of medicinal use.
• While its anti-tumor properties are known, its anti-metastatic effects are a recent area of research.

Purpose of the Study:

• To review the anti-metastatic effects of saffron, crocin, and crocetin.
• To elucidate the underlying mechanisms of their anti-metastatic actions.

Main Methods:

• Literature review of studies investigating saffron and its carotenoids' effects on cancer metastasis.
• Analysis of mechanisms including cell migration, invasion, angiogenesis, and specific molecular pathways.

Main Results:

• Saffron and its carotenoids inhibit cancer cell migration, invasion, and angiogenesis.
• They modulate pathways like Wnt/β-catenin, Ras/ERK, and EMT, and affect cell adhesion.
• Crocin demonstrated superior anti-metastatic potency compared to saffron extract and crocetin.

Conclusions:

• Saffron, crocin, and crocetin exhibit significant anti-metastatic properties.
• Their non-toxicity and anti-tumor efficacy support their potential as dietary agents and herbal medicines for cancer treatment.
