Brief Summary
Maternal obesity (MO) affects 1 in 5 women and is strongly linked to increased birth weight, childhood/adolescent obesity, life-long metabolic and inflammatory disorders, and childhood neuropsychiatric disorders. There remains a critical unmet need for developing a safe and effective non-pharmacological approach for attenuating metabolic inflammation and ameliorating the adverse effects of MO on offspring health that originate in utero and extend into the lactational period. Pyrroloquinoline quinone (PQQ) is a diet-derived natural food supplement with anti-inflammatory properties that, in humans and mice, improves metabolism and exerts potent immunoregulatory effects. Researchers' central hypothesis is that PQQ administration during MO pregnancy 1) improves maternal metabolic and inflammatory indices, 2) improves utero-placental blood flow and ameliorates placental maladaptation (oxidative stress, hypoxia, inflammation and fatty acid transporter expression) and 3) reduces neonatal adiposity.
