Crocetin Alleviates Ovariectomy-Induced Metabolic Dysfunction through Regulating Estrogen Receptor β

Area of Science:

• Biochemistry
• Metabolic Health
• Pharmacology

Background:

• Metabolic dysfunction (MD) significantly impacts menopausal women's quality of life.
• Saffron is traditionally used for menopausal symptoms, but its mechanisms are unclear.
• Understanding saffron's active compounds is crucial for therapeutic applications.

Purpose of the Study:

• To investigate the effects of crocin and crocetin on metabolic dysfunction and lipid metabolism.
• To elucidate the underlying mechanisms, particularly the role of estrogen receptor beta (ERβ).
• To evaluate the therapeutic potential for menopausal women.

Main Methods:

• Ovariectomized (OVX) mice model for metabolic dysfunction.
• 3T3-L1 adipocytes for in vitro studies.
• Analysis of weight gain, fat accumulation, insulin resistance, energy expenditure, and fat oxidation.
• Investigation of adipogenic and lipolytic factors and ERβ function.

Main Results:

• Crocin administration prevented weight gain, fat accumulation, and insulin resistance in OVX mice.
• Crocin increased energy expenditure and fat oxidation.
• Crocin and crocetin improved adipose tissue homeostasis and lipid metabolism, linked to ERβ restoration.

Conclusions:

• Crocin/crocetin interventions show beneficial effects against metabolic dysfunction in menopausal models.
• The mechanism involves regulating adipogenic/lipolytic factors and restoring ERβ function.
• Saffron compounds offer a promising therapeutic strategy for metabolic health in menopausal women.
