Abstract
- In 1983, three of us reported in “Science” that umbilical-placental arteries and veins, obtained from normal pregnant women at term delivery, when exposed in vitro to low concentrations of Mg2+ went into vasospasm; the lower the Mg2+, the greater the contractile force developed. These blood vessels also demonstrated amplified contractile force development when challenged with circulating amines and peptides (e.g., norepinephrine, 5-HT, angiotensin II, etc.). We suggested that severe Mg deficiency during pregnancy could in part be responsible for spontaneous abortions, loss of fetuses, stillbirths, and developmental alterations in infants. Using short-term dietary Mg deficient animals, we have noted a great many molecular and biochemical alterations in ventricular, atrial and somatic vascular smooth muscle alterations including DNA methylation and histone changes leading us to speculate that Mg deficiency may represent a genotoxin promoting mutations and causing epigenetic changes. Over the last 35 years, we have new data on severely preeclamptic and gestational diabetic pregnant women that gives credence to our original hypothesis and demonstrates that recently- discovered developmental proteins, originally found 100 years ago in Drosophila fruit flies termed the “Notch pathway”, due to effects on its wings, appears to be important in development of the umbilical-placental blood vessels in pregnant women. Along with the developmental molecule, p53, these Notch proteins clearly alter the behavior of the umbilical-placental vessels. We believe these new findings probably help to explain many of the genetic-toxicity effects seen in women later in life who develop strokes and cardiovascular diseases. Notch alterations could also play an important role in babies born with cardiac defects.
