Cardiac hypertrophy is one of the key structural changes in diabetic cardiomyopathy. Naringenin, a dihydroflavonoid extracted from citrus plants with multiple pharmacological activities, yet the underlying effects on diabetic cardiac hypertrophy remain unclear. This study aimed to evaluate the potential effects of naringenin on cardiac hypertrophy in diabetic mice. Long-term high-fat feeding combined with streptozotocin resulted in cardiac hypertrophy after a diabetic model has been established for 4 weeks in mice, which were improved by naringenin supplementation (25 or 75 mg/kg/day, i. g.) for another 4 weeks. The protein and mRNA expressions of PPARs were down-regulated, the protein express of CYP2J3 and level of 14, 15-EET were decreased following diabetic cardiac hypertrophy. Naringenin administration up-regulated PPARs expression, elevated CYP2J3 protein and 14,15-EET content. In conclusion, naringenin can improve cardiac hypertrophy in diabetic mice, which may be related to up-regulate the expression of CYP2J3, elevate the level of EETs, and activate the expression of PPARs.
