Zearalenone exacerbates lipid metabolism disorders by promoting liver lipid droplet formation and disrupting gut microbiota.

Zearalenone (ZEA), produced by Fusarium, is a fungal toxin commonly found in maize, wheat, and other cereals. ZEA has the ability to bind to estrogen receptors of humans and animals and is an environmental endocrine disruptor that may interfere with glucose homeostasis and lipid metabolism. In this study, we first investigated the effects of chronic exposure to low doses of ZEA with a high-fat-diet (HFD) in obese C57BL/6 J mice.

Targeting Odorant Receptors in Adipose Tissue with Food-Derived Odorants: A Novel Approach to Obesity Treatment.

Odorant receptors (ORs) have long been thought to serve as chemosensors located on the cilia of olfactory sensory neurons (OSNs) in the olfactory epithelium, where they recognize odorant molecules and comprise the largest family of seven transmembrane-domain G protein-coupled receptors (GPCRs). Over the last three decades, accumulating evidence has suggested that ORs are distributed in a variety of peripheral tissues beyond their supposed typical tissue expression in the olfactory epithelium. These ectopic ORs play a role in regulating various cellular, physiological, and pathophysiological phenomena in the body, such as regulation of hypertension, hepatic glucose production, cancer development, and chronic skin disease.
