Surprisingly, CBA/CaJ mice exhibited reduced glucose levels when exposed to LL with corresponding increases to serum insulin; other studies usually report that circadian disruption leads to both hyperinsulinemia and hyperglycemia, which are symptoms of a type 2 diabetic-like state (as summarized by Vinogradova et al. (2009)33). The gene discussed is INS; the disease is Hyperinsulinemia.
