Receptor Modulation

Psychological stress and excess glucocorticoids are associated with metabolic and cardiovascular diseases. Glucocorticoids act primarily through mineralocorticoid (MR) and glucocorticoid receptors (GR), and compounds modulating these receptors show promise in mitigating metabolic and cardiovascular-related phenotypes. CORT118335 (GR/MR modulator) prevents high-fat diet-induced weight gain and adiposity in mice, but the ability of this compound to reverse obesity-related symptoms is unknown. Adult male rats were subcutaneously administered CORT118335 (3, 10, or 30 mg/kg) or vehicle once daily. A 5-day treatment with CORT118335 at 30 mg/kg induced weight loss in rats fed a chow diet by decreasing food intake. However, lower doses of the compound attenuated body weight gain primarily because of decreased calorific efficiency, as there were no significant differences in food intake compared with vehicle. Notably, the body weight effects of CORT118335 persisted during a 2-wk treatment hiatus, suggesting prolonged effects of the compound. To our knowledge, we are the first to demonstrate a sustained effect of combined GR/MR modulation on body weight gain. These findings suggest that CORT118335 may have long-lasting effects, likely due to GR/MR-induced transcriptional changes. Prolonged (18 days) treatment of CORT118335 (10 mg/kg) reversed body weight gain and adiposity in animals fed a high-fat diet for 13 wk. Surprisingly, this occurred despite a worsening of the lipid profile and glucose homeostasis as well as a disrupted diurnal corticosterone rhythm, suggesting GR agonistic effects in the periphery. We conclude that species and tissue-specific targeting may result in promising leads for exploiting the metabolically beneficial aspects of GR/MR modulation.

Diet Induced Obesity

Obesity in itself is a disease condition and a major risk factor in the development of hypertension, dyslipidemia, and hyperglycemia. Therefore, successful strategies for improving obesity and related metabolic risk factors are needed. Role of renin-angiotensin system (RAS) has been implicated in obesity and metabolic dysfunction. Recently, we have shown that AT2R knock-out in female mice caused a greater body weight gain and hyperinsulimia in response to high fat diet (HFD). In the present study, we hypothesize that AT2R activation rescues diet-induced obesity in females. To test this hypothesis, we injected AT2R non-peptide agonist C21 (0.3mg/kg/day i.p) in C57BL6 female mice on HFD for 12 weeks. C21-treatment did not affect the HFD calorie intake (HFD: 937±18 Kcal; C21HFD: 886±37 Kcal) but caused lesser body weight gain compared to control (HFD: 4.4± 0.4g; C21HFD: 3.06± 0.4g). Similar to the body weight gain pattern, gonadal fat weight and adipocyte size were decreased significantly in C21-treated mice on HFD compared to control HFD group (HFD: 4.4± 0.4 g; C21 HFD: 3.06± 0.4g) and (HFD: 6404±161.6μm2 ; C21HFD: 3874±103.2μm2 ) respectively. Moreover, the C21-treated females on HFD had lower levels of plasma insulin, improved glucose tolerance, and decreased plasma free fatty acids and hepatic triglycerides. Western blot revealed that phospho-Ser79-acetyl CoA carboxylase (p-Ser79-ACC-1) was reduced, an index of increased lipogenic activity and decreased β-oxidation process, in both adipose (Adi) and hepatic (Hep) tissues of HFD fed groups (Adi: 86% and Hep: 73% of 100% controls); C21-treatment revered the decrease in p-ser79-ACC-1 in Adi (104% of control) and caused an increase in Hep (122% of control) respectively. The HFD feeding lowered the estradiol level (ND: 38.8±2.6 vs HFD:11.3±1.2ng), which was modestly reversed by C21 treatment (C21HFD:17.4± 1.5ng) in HFD mice. Our results strongly suggest that stimulation of AT2R in female mice positively contribute, predominantly independent of estrogen, to rescue body weight gain and adipocyte size increase in response to HFD. We propose reduced lipogenesis and enhanced lipid β-oxidation as potential mechanisms linked to AT2R action in reducing obesity and its related metabolic disorders in females.

Inflammation and immunity are linked to the onset and development of obesity and metabolic disorders. Pattern recognition receptors (PRRs) are key regulators of inflammation and immunity in response to infection and stress, and they have critical roles in metainflammation. In this study, we investigated whether RIG-I (retinoic acid-inducible gene I)-like receptors were involved in the regulation of obesity-induced metabolic stress in RIG-I knockout (KO) mice fed a high-fat diet (HFD). RIG-I KO mice fed an HFD for 12 weeks showed greater body weight gain, higher fat composition, lower lean body mass, and higher epididymal white adipose tissue (eWAT) weight than WT mice fed HFD. In contrast, body weight gain, fat, and lean mass compositions, and eWAT weight of MDA5 (melanoma differentiation-associated protein 5) KO mice fed HFD were similar to those of WT mice fed a normal diet. RIG-I KO mice fed HFD exhibited more severely impaired glucose tolerance and higher HOMA-IR values than WT mice fed HFD. IFN-β expression induced by ER stress inducers, tunicamycin and thapsigargin, was abolished in RIG-I-deficient hepatocytes and macrophages, showing that RIG-I is required for ER stress-induced IFN-β expression. Our results show that RIG-I deficiency promotes obesity and insulin resistance induced by a high-fat diet, presenting a novel role of RIG-I in the development of obesity and metabolic disorders.
