Hyperglycemia and reproductive defects in non-diabetic gravidas: a mouse model test of a new theory
Abstract:
The frequent association of various reproductive anomalies with maternal diabetes is explained by a theory that predicts such defects will occur even in transient moderate hyperglycemia in non-diabetic gravidae. A first test of this hypothesis produced strongly supportive results in a mouse model. Thirteen C57BL/6J dams on a grain (control) diet produced (in the 4th week after first mating) 64 pups, 62 surviving to maturity. In the same time interval on a high sucrose diet, fourteen isogenic dams produced only 5 pups, none surviving 5 days (p much less than .001). Additional ongoing studies of the underlying glucose-ascorbate antagonism and of early vs. perinatal hyperglycemia are described briefly.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
