Obesity appears to be a major contributing factor for many health problems. Effective treatments for reducing weight gain, other than caloric restriction and exercise, are limited. The consumption of sugars is a major factor in the development of obesity in part by stimulating the transcription factor, carbohydrate response element binding protein (ChREBP), a process that is driven by de novo lipogenesis. Therefore, we hypothesized that inhibiting the action of ChREBP would be a promising strategy for alleviating these diseases. Using ChREBP deficient mice, the effect of a high intake of sucrose on body weight and blood glucose levels were investigated. Unlike wild type mice, ChREBP deficient mice did not gain much weight and their blood glucose and cholesterol levels remained relatively constant. In tracing it’s cause, we found that the levels of expression of sucrase, an enzyme that digests sucrose, and both Glut2 and Glut5, a transporter of glucose and fructose, were not induced by feeding a high sucrose diet in the small intestine of ChREBP deficient mice. Our findings suggest that the inhibition of ChREBP could suppress weight gain even on a high sucrose diet.

Background: The place of death and related factor, such as diseases, symptoms, family burden, and cost, has been examined, but social background and lifestyle were not considered in most studies. Here, we assessed factors that are associated with the place of death using the largest cohort study in Japan.Methods: A total of 17,781 deaths from the cohort study were assessed. The study database was created from the Japan Public Health Center-based Prospective Study (JPHC Study), in which demographic data were collected from Japanese Vital Statistics. Adjusted odds ratios for home death were calculated using logistic regression.Results: Multivariate analysis adjusted for various factors showed that unmarried status (odds ratio [OR] 2.4; 95% confidence interval [CI], 2.0–2.9), unemployed male (OR 1.3; 95% CI, 1.1–1.5), and high drinking level in male (OR 1.3; 95% CI, 1.1–1.6) were associated with home death. Regarding the cause of death, cardiovascular disease (OR 3.3; 95% CI, 2.9–3.8), cerebrovascular disease (OR 1.9; 95% CI, 1.6–2.2), and external factors (OR 4.1; 95% CI, 3.5–4.8) were significantly associated with home death, compared with cancer. The risk of death at home was significantly higher among unmarried subjects stratified by cause of death (cardiovascular disease: OR 3.2; 95% CI, 2.2–4.7; cerebrovascular disease: OR :5.1; 95% CI, 2.9–9.1; respiratory disease: OR 3.4; 95% CI, 1.6–7.6; and external factors: OR 2.3; 95% CI, 1.4–3.7), but for cancer, the risk of death at home tended to be higher among married participants.Conclusion: This study found that various factors are associated with home death using the largest cohort study in Japan. There is a high possibility of home deaths in people with fewer social connections and in those with diseases leading to sudden death.
