Clock Modulation by Naringenin Suppresses Lipogenesis and Promotes Adipose Tissue Browning

Area of Science:

• Metabolism and Endocrinology
• Chronobiology
• Molecular Biology

Background:

• Circadian clock disruption is linked to obesity and insulin resistance.
• Adipocyte function and lipid metabolism are regulated by the circadian clock.
• Flavonoids are plant compounds with potential health benefits.

Purpose of the Study:

• To investigate the effects of naringenin on the circadian clock and adipocyte metabolism.
• To explore naringenin's potential as an anti-obesity and metabolic disease intervention.

Main Methods:

• In vitro studies using adipogenic progenitors and mature adipocytes.
• In vivo studies involving naringenin administration in animal models.
• Analysis of gene expression, lipid storage, and metabolic parameters.

Main Results:

• Naringenin activates RORα and enhances circadian clock gene expression.
• Naringenin suppresses lipogenesis and promotes adipocyte browning.
• In vivo studies show reduced fat mass, body weight, and improved glucose/lipid levels.
• Naringenin treatment enhances insulin signaling in adipose tissue and skeletal muscle.

Conclusions:

• Naringenin exhibits clock-modulatory activity, offering metabolic benefits.
• Naringenin's anti-obesity effects are mediated through RORα activation and clock enhancement.
• Naringenin shows potential as a natural supplement for metabolic health.
