(1) Maternal TCDD exposure exacerbates prenatal DEX-induced hypertension in adult male offspring; (2) maternal resveratrol therapy prevents combined DEX and TCDD exposure-induced programmed hypertension, which is related to decreased ADMA and SDMA levels; (3) maternal TCDD exposure aggravates DEX-induced oxidative damage in offspring kidneys, which resveratrol therapy prevented; and (4) the beneficial effects of resveratrol on DEX + TCDD-induced hypertension relates to reduced renal mRNA expression of Ahrr, Ren, Ace, and Agtr1a expression. The gene discussed is AGTR1; the disease is Hypertension.
