Although previous investigations about the potential effects of PRL in T2DM and its complications are scarce, existing experimental studies suggest an influence of PRL on T2DM via its metabolic effects on adipose tissue [2,3], development and growth of pancreatic ß-cells [6,7], insulin resistance [3,8], and lipid metabolism [3,9]. The gene discussed is PRL; the disease is type 2 diabetes mellitus.
