Abstract

Rats were given 5, 10, 20 and 30 min daily sessions of lateral hypothalamic stimulation. Approximately half of the rats showed a large and highly significant increase in their total intake of and preference for 10% v/v ethanol which was continuously available in their home cages. In terms of latency, total consumption and preference for ethanol, 10 min of daily stimulation produced a much greater enhancement than did 30 min. The ethanol drinking rats used more energy per unit of body weight which suggests that the stimulation and/or the ethanol itself may have increased energy expenditure. Simply changing the diet from powdered chow to identical composition pellets produced a large reduction in both total ethanol intake and preference. Reinstating the powdered diet produced a rapid reinstatement of ethanol drinking. These data are discussed in terms of ethanol's role in modulating stimulation induced changes in energy balance.

FGF21 suppresses alcohol consumption through an amygdalo-striatal circuit.

Excessive alcohol consumption is a major health and social issue in our society. Pharmacologic administration of the endocrine hormone fibroblast growth factor 21 (FGF21) suppresses alcohol consumption through actions in the brain in rodents, and genome-wide association studies have identified single nucleotide polymorphisms in genes involved with FGF21 signaling as being associated with increased alcohol consumption in humans. However, the neural circuit(s) through which FGF21 signals to suppress alcohol consumption are unknown, as are its effects on alcohol consumption in higher organisms. Here, we demonstrate that administration of an FGF21 analog to alcohol-preferring non-human primates reduces alcohol intake by 50%. Further, we reveal that FGF21 suppresses alcohol consumption through a projection-specific subpopulation of KLB-expressing neurons in the basolateral amygdala. Our results illustrate how FGF21 suppresses alcohol consumption through a specific population of neurons in the brain and demonstrate its therapeutic potential in non-human primate models of excessive alcohol consumption.

Alcohol intake and colorectal cancer risk: a dose-response meta-analysis of published cohort studies.

The epidemiologic evidence support that alcohol intake might be associated with increased colorectal cancer risk. However, the results by anatomic site in the large bowel are inconsistent. We conducted a meta-analysis of prospective cohort studies published between 1990 and June 2005 on the relationship between alcohol intake and colon and rectal cancer. We quantified associations with colon and rectal cancer using meta-analysis of relative risk (RR) associated to the highest versus the lowest category of alcohol intake and meta-analysis of study-specific dose-response slopes using fixed or random effect models depending on the heterogeneity of effects among studies. Sixteen prospective cohort studies including more than 6,300 patients with colorectal cancer were eligible for inclusion. High alcohol intake was significantly associated with increased risk of colon (RR = 1.50; 95% CI = 1.25, 1.79) and rectal cancer (RR = 1.63; 95% CI = 1.35, 1.97) when comparing the highest with the lowest category of alcohol intake, equivalent to a 15% increase of risk of colon or rectal cancer for an increase of 100 g of alcohol intake per week. The relationship did not differ significantly by anatomical site (colon, rectum). Using meta-regression analysis, we identified geographical area where the study was conducted as a possible source of between-study heterogeneity of effects among studies. Lifestyle recommendations for prevention of colorectal cancer should consider limiting alcohol intake.
