Obesogens, such as bisphenol A (BPA), are emerging models for obesity research, yet their mechanisms remain less explored. While BPA has been extensively studied for its estrogen receptor interactions, its effects on the glucocorticoid receptor (GR) remain unclear. This study explored the role of the GR in BPA-induced lipid accumulation using the GR antagonist mifepristone (10 μM) and the PPAR-γ antagonist GW9662 (15 μM) in 3T3-L1 preadipocytes.

Obesity due to excessive fat accumulation, affects health and quality of life and increases the risk of diseases such as type 2 diabetes and cardiovascular conditions. Traditional causes, such as calorie excess and sedentary behavior, do not fully explain the obesity epidemic, leading to the hypothesis that endocrine-disrupting chemicals or obesogens contribute to obesity. The obesogenic mechanisms of representative obesogenic substances, such as bisphenols, have been discussed, mainly focusing on their interactions with estrogen receptors.

Unlabelled: This study investigated the potential of sauce meeting the functional labeling system (TSF) with resistant maltodextrin on muscle atrophy using dexamethasone-induced C2C12 myotubes and hindlimb immobilization (HI)-induced C57BL/6J mice. TSF significantly improved cell viability, myotube diameter, and fusion index in C2C12 myotubes. Furthermore, TSF effectively mitigated HI-induced muscle atrophy in mice, enhanced grip strength, and increased muscle mass.

This study investigated the potential ameliorative effects of fermented red ginseng (FRG) extract on sarcopenia-related muscle atrophy in old mice and elucidated the underlying mechanisms. Mice, aged five and twenty months, were divided into seven groups: young and old controls, and old mice treated with extract (200 mg/kg/day), mixed ginsenosides (15 mg/kg/day), and FRG extract (50-200 mg/kg/day). Body weight and grip strength were assessed weekly.

Bisphenol A (BPA) is a representative obesogen that induces adipocyte differentiation and lipid accumulation by mimicking the action of hormones. is a plant belonging to the mustard family, and has antioxidant, anti-inflammatory, and anti-obesity effects. However, its efficacy against obesogen-induced obesity requires further investigation.

Fermented red ginseng (FRG) enhances the bioactivity and bioavailability of ginsenosides, which possess various immunomodulatory, antiaging, anti-obesity, and antidiabetic properties. However, the effects of FRG extract on muscle atrophy and the underlying molecular mechanisms remain unclear. This study aimed to elucidate the effects of FRG extract on muscle atrophy using both and models.

Obesity is a global health concern. Recent research has suggested that the development of anti-obesity ingredients and functional foods should focus on natural products without side effects. We examined the effectiveness and underlying mechanisms of extract (BJE) in combating obesity via experiments conducted in both in vitro and in vivo obesity models.

Sulforaphane (SFN) is an isothiocyanate commonly found in cruciferous vegetables. It is formed via the enzymatic hydrolysis of glucoraphanin by myrosinase. SFN exerts various biological effects, including anti-cancer, anti-oxidation, anti-obesity, and anti-inflammatory effects, and is widely used in functional foods and clinical medicine.
