Abstract excerpt
The insulin gene is specifically expressed in pancreatic islet beta cells. Various cis-acting DNA elements in the 5'-flanking region of the human insulin gene were examined for their contribution to the transcriptional activity using sensitive human growth hormone (hGH) reporter plasmids. The hGH constructs, having successively deleted human insulin promoter sequences, were transfected to a pancreatic islet...
