We thank Masotti (1) for his interest and comment in this issue of Diabetes on our recently published article (2). In his letter, Masotti proposed, on the basis of our study findings and those from his own laboratory, that the glycolytic/gluconeogenic pathways may play an integral role in body weight regulation.
Fructose-1,6-bisphosphate is not only the key substrate in gluconeogenesis for fructose-6-phosphate production but is also the substrate for the production of glyceraldehyde-3-phosphate and dihydroxyacetone phosphate via the enzyme aldolase A (ALDOA)—a glycolytic-pathway activated reaction. Masotti and colleagues (3) recently demonstrated that increased expression of microRNA-122 was associated with the development of nonalcoholic fatty liver disease in rats fed a …
