| Title: | Prolonged-release pirfenidone prevents obesity-induced cardiac steatosis and fibrosis in a mouse NASH model. |
| Abstract: | PURPOSE: Obesity is associated with systemic insulin resistance and cardiac hypertrophy with fibrosis. Peroxisome proliferator-activated receptors (PPARs) regulate carbohydrate and lipid metabolism, improving insulin sensitivity, triglyceride levels, inflammation, and oxidative stress. We previously demonstrated that prolonged-release pirfenidone (PR-PFD) is an agonistic ligand for Pparα with anti-inflammatory and anti-fibrotic effects, and might be a promising drug for cardiac diseases-treatment. Here, we investigated the effects of PR-PFD in ventricular tissue of mice with nonalcoholic steatohepatitis (NASH) and obesity induced by high-fat/high-carbohydrate (HFHC) diet. METHODS: Five male C57BL/6 J mice were fed with normal diet (ND) and ten with HFHC diet for 16 weeks; at 8 weeks of feeding, five mice with HFHC diet were administered PR-PFD (350 mg/kg/day) mixed with HFHC diet. RESULT: Systemic insulin resistance, heart weight/body weight ratio, myocardial steatosis with inflammatory foci, hypertrophy, and fibrosis were prevented by PR-PFD. In addition, HFHC mice showed significantly increased desmin, Tgfβ1, Timp1, collagen I (Col I), collagen III (Col III), TNF-α, and Nrf2 mRNA levels, including α-SMA, NF-kB, Nrf2, troponin I, Acox1, Cpt1A, and Lxrα protein levels compared with the ND ventricular tissues. Mechanistically, HFHC mice with PR-PFD treatment significantly decreased these genes overexpressed by HFHC diet. Furthermore, PR-PFD overexpressed the Pgc1a mRNA levels and Pparα, Pparγ, Acox1, and Cpt1A protein levels. CONCLUSIONS: The results suggest that PR-PFD could be a promising drug for the prevention and treatment of cardiac steatosis and fibrosis induced by obesity. |
