What is the relationship between cardiovascular developmental programming and the risk of stroke later in life? Listen as Guest Editor Dr. Helen E. Collins (University of Louisville) interviews author Dr. Nafisa Jadavji (Midwestern University) and expert Dr. Deanne Hryciw (Griffith University) about the latest research by Pull et al. looking at underlying mechanisms associated with a poor-quality diet during pregnancy. One-carbon metabolism is essential for biosynthesis of DNA and proteins, as well as methylation. Jadavji and co-authors demonstrated that maternal dietary deficiency in one-carbon (1C) metabolism, either in folic acid or choline, resulted in reduced cerebral blood flow in adult offspring after an ischemic stroke. Pull et al. focused their investigation on female offspring and identified this effect in 3-month-old offspring but not 11-month-old offspring. The results point to the key role that maternal diet has in early life programming, fetal development, and long-term cerebrovascular health. Are there many downstream pathways that are altered by one-carbon metabolism deficiencies? Is there a negative impact of folic acid over-supplementation? Listen now to find out.
