The current state of the HISS (hepatic insulin sensitizing substance) hypothesis is briefly outlined. In the postmeal absorptive state, 50-60% of the glucose storage action of insulin is accounted for by the actions of HISS released from the liver and acting on skeletal muscle. Hepatic parasympathetic nerves permissively regulate the ability of a pulse of insulin to release HISS, thereby potentiating the impact of insulin in the fed state. HISS release in response to insulin decreases progressively with fasting to create a physiological state of HISS-dependent insulin resistance. HISS release is regulated by parasympathetic nerves via muscarinic receptors and nitric oxide, and insulin resistance of skeletal muscle produced by hepatic denervation is reversed by intraportal but not intravenous acetylcholine or a nitric oxide donor. It is suggested that HISS-dependent insulin resistance occurs in animal models including sucrose-fed rats, spontaneously hypertensive rats, chronic liver disease, fetal alcohol effect in the adult offspring, and type 2 diabetes.

Adolescence is a developmental stage vulnerable to alcohol drinking-related problems, and alcohol exposure during adolescence may lead to long-lasting consequences. The hypothalamus is a key brain region for food and water intake regulation as well as weight control, and is one of the alcohol-sensitive brain regions. However, it is not known what the alcohol effect is on the hypothalamus following adolescent alcohol intake, chronically over adolescent development, at moderate levels. We employed a model of chronic moderate alcohol intake from adolescence to adulthood in mice, and analyzed the effect of alcohol on growth and weight gain, as well as hypothalamic gene expression patterns. The results indicated that chronic alcohol consumption during adolescence, even at moderate levels, led to both a reduction in weight gain in mice, and considerable gene expression changes in the hypothalamus. Pathway analysis and real-time PCR identified the type II diabetes mellitus and the insulin-signaling pathways as being the hypothalamic pathways affected by chronic alcohol. Our findings from the mouse alcohol consumption study therefore serve as a potential warning against alcohol consumption during adolescence, such as in teens and college students.
