Pioglitazone, a Specific Ligand of the Peroxisome Proliferator-Activated Receptor Gamma Reduces Gastric Mucosal Injury Induced by Ischaemia/Reperfusion in Rat

Abstract

Pioglitazone reduces the acute erosions and deeper gastric lesions induced by I/R. The beneficial effect of this PPARgamma ligand on I/R-induced gastric damage may be due to its anti-inflammatory properties, especially to the reduction in TNF-alpha expression and to up-regulation of leptin mRNA in the gastric mucosa. The inhibition of COX-2 expression by pioglitazone may reflect the anti-inflammatory properties of this compound.
