Abstract

We have determined that changes in the expression of 6-Phosphofructo-2-Kinase/Fructose-2,6-Bisphosphatase mRNA in streptozotocin-diabetic rats vary in different organs. The expression of different splice variants of PFKFB-3 mRNA is organ specific and changes in diabetes. We have identified new splice variant of PFKFB-3 mRNA which has catalytic domains identical to those of the main isoform and other alternative splice variants of PFKFB-3 but differs by the length of C-terminus. Results of this investigation support possible role of PFKFB-3 isozymes in adaptation of the cells to disordered carbohydrate metabolism resulting from the insulin deficiency.
Keywords: PFKFB-3 mRNA, alternative splicing, streptozotocin-diabetes, rats
