Abstract
A transgenic animal containing germ cells and somatic cells which contain a non-native recombinant gene which codes upon expression hexokinase capable of expressing hexokinase at significantly increased levels for study of the role of hexokinase in diabetes and other diseases. When these transgenic animals were exposed to a calmodulin stimulated model of diabetes increased levels of hexokinase activity were able to promote insulin secretion thereby reducing glucose levels in blood and transiently reduce the effects of diabetes.
Claims2
A transgenic mouse whose germ cells and somatic cells comprise a gene construct comprising a rat insulin II promoter operably linked to a yeast hexokinase gene, wherein said gene construct is integrated into the genome of the transgenic mouse, wherein said hexokinase gene is expressed in the pancreatic beta cells of said transgenic mouse, and wherein expression of said hexokinase gene results in increased insulin and glucose levels in the blood of the transgenic mouse, compared with the insulin and glucose levels in the blood of a mouse that does not express a yeast hexokinase gene in its beta cells.
