Abstract:

SCOPE: Perinatal high-fat (HF) diet induces hypertension in adult offspring. Garlic, a naturally dietary source of Hydrogen sulfide (HS) donor, has been shown benefits in hypertension. We examined whether maternal garlic oil supplementation can prevent hypertension induced by HF diet and elucidated its protective effects.

METHODS AND RESULTS: Pregnant rats received either a normal diet or HF diet. Rat dams were given garlic oil or vehicle daily by oral gavage at 100 mg/kg/day during pregnancy and lactation. Male offspring were sacrificed at 16 weeks of age. Garlic oil supplementation during pregnancy and lactation protected against hypertension induced by HF diet in adult male offspring. The beneficial effects of garlic oil were associated with increased renal mRNA expression and activity of HS-generating enzymes, increased NO bioavailability, increased plasma short chain fatty acid levels, and alterations of gut microbiota composition. Garlic oil supplementation increased abundance of genus Lactobacillus, but decreased genera Turicibacter and Staphylococcus.

CONCLUSION: Our data revealed associations between HS-generating pathway in the gut and kidneys, NO system, gut microbiota, and microbiota-derived metabolites in hypertension induced by HF intake and provided insight to garlic oil as a hypertension reprogramming strategy for further translational research.
