We evaluated whether high-fat diet (HFD), in the absence of increased calorie intake, increases colon cancer growth and metastasis. Four-week-old male BALB/c mice were fed on an HFD (60kcal% fat) or control diet (10kcal% fat) for 16wk, after which CT26 colon cancer cells were subcutaneously injected into the right flank. Solid tumor growth and the number and volume of tumor nodules in the lung were increased markedly in the HFD group with only a slight increase in body weight (5.9%). HFD feeding increased tumor tissue levels of Ki67, cyclin A, cyclin D1, CDK2, Bcl-xL, and Bcl-2; reduced p53 levels and TUNEL-positive apoptotic cells; increased the levels of CD45, CD68, CD31, VEGF, P-VEGF receptor-2, iNOS, and COX-2 as well as hemoglobin content; and increased the levels of HIF-1α, P-STAT3-Y705, P-STAT3-S727, P-IκB-α, P-p65, p65, P-c-Jun, P-Akt, P-ERK1/2, P-p38, and P-SAPK/JNK. HFD feeding increased the serum levels of EGF, insulin, IGF-I, IFN-γ, leptin, RANTES, MCP-1, IL-1ra, and SDF-1α and media conditioned by epididymal fat tissue explants from HFD-fed mice caused an increase in microvessel outgrowth from the mouse aorta and tube formation of human umbilical vein endothelial cells. These results indicate that the chronic consumption of an HFD increases colon cancer cell proliferation, tumor angiogenesis, and lung metastasis in mice in the absence of discernible weight gain. HFD feeding increases the levels of growth factors which activate transcription factors, thereby inducing the expression of many genes involved in the stimulation of inflammation, angiogenesis, and cellular proliferation. © 2011 Wiley Periodicals, Inc.

Background: Prolactin improves glucose homeostasis by increasing β-cell mass under certain conditions such as pregnancy, whereas hyperprolactinaemia due to a pituitary gland adenoma tumour exacerbates insulin resistance. However, previous studies have not evaluated how prolactin modulates β-cell function and insulin sensitivity at different dosages. Here, we determined that chronic intraperitoneal injections of different dosages of prolactin have opposite effects on insulin resistance and β-cell function and mass in 90% pancreatectomized diabetic male rats, and the mechanisms were explored. Methods: Diabetic rats were divided into three groups according to the dose of intraperitoneally injected prolactin for 4 weeks: (1) low dose of prolactin (25 μg/kg bw/12 h), (2) high dose of prolactin (250 μg/kg bw/12 h), and (3) vehicle. As a non-diabetic control group, sham-operated rats were injected with vehicle. Results: Chronic high- and low-dose prolactin injections elevated serum prolactin levels by 2.5- and 11.8-fold, respectively. Both dosages promoted β-cell mass by increasing β-cell proliferation and neogenesis through the potentiation of phosphorylation of signal transducer and activator of transcription 5 and decreased menin expression in diabetic rats. However, only the low-dose prolactin injection potentiated glucose-stimulated insulin secretion though glucokinase and glucose transporter 2 induction in the diabetic rats. In addition, low-dose prolactin decreased hepatic glucose output in hyperinsulinaemic states, indicating an improvement in hepatic insulin resistance. However, the high-dose prolactin injection exacerbated whole-body and hepatic insulin resistance in diabetic rats. Conclusions: In contrast to the normal adaptive increases in glucose-stimulated insulin secretion through expanded β-cell mass and insulin sensitivity realized with moderately increased prolactin levels, high levels of prolactin exacerbate insulin resistance and impair the insulin-secretory capacity in diabetic mice. © 2011 John Wiley and Sons, Ltd.

Objectives: Brain-derived neurotrophic factor (BDNF) is associated with the risk for Alzheimer's disease and type 2 diabetes. The aim of this study was to examine the association of . BDNF variants with type 2 diabetes and the interactions of different . BDNF genotypes with dietary habits and food and nutrient intakes in middle-aged adults. Methods: The study population included 8840 adults ages 40 to 65 y from the Ansan and Asung areas in the Korean Genome Epidemiology Study, a cross-sectional study of Korean adults, conducted from 2001 to 2002. Adjusted odd ratios for the prevalence of glucose intolerance and type 2 diabetes according to . BDNF genotypes were calculated after adjusting for age, sex, residence area, body mass index, physical activity, and smoking and stress status. Nutrient intake was calculated from usual food intake determined by semiquantitative food frequencies using the nutrient assessment software. Results: . BDNF rs6265 Val/Met and Met/Met variants were negatively associated with the risk for type 2 diabetes after adjusting for covariates. Serum glucose levels after glucose loading and hemoglobin A1c, but not serum insulin levels, also were negatively associated with . BDNF Val/Met and Met/Met. In subgroup analysis, sex and stress levels had an interaction with . BDNF Val/Met in the risk for type 2 diabetes. Glucose-intolerant and diabetic, but not nondiabetic, patients with . BDNF Met/Met had nominally, but significantly higher intakes of energy than those with . BDNF Val/Val. . BDNF rs6265 had consistent gene-diet interactions with energy and protein intake. With low-energy, low-protein, and high-carbohydrate intake, . BDNF Val/Met lowered the risk for type 2 diabetes after adjusting for confounding factors. . BDNF Val/Met did not compensate for developing type 2 diabetes with high-energy intake. Additionally, indexes of insulin resistance and insulin secretion showed the same gene-energy interaction as type 2 diabetes. Conclusions: . BDNF Val/Met and Met/Met variants (rs6265) decreases the risk for glucose intolerance and type 2 diabetes. . BDNF variants interacted with nutrient intake, especially energy and protein intake: Middle-aged individuals with . BDNF Val/Val are prone to developing type 2 diabetes even with low energy and protein intake. © 2016 Elsevier Inc.

Although the effects of ketogenic diets on energy and glucose homeostasis have been controversial, elevation of serum ketone levels by subcutaneous injection of β-hydroxybutyrate (BHB) can improve glucose homeostasis. Ketones may work through the brain; therefore, we evaluated whether the intracerebroventricular (ICV) infusion of β-hydroxybutyrates would also modulate peripheral energy and glucose homeostasis, and through what mechanisms, in diabetic rats fed a high fat diet in short- and long-term studies. Short-term (3 h) central injection of BHB (50 μg/h) improved serum glucose levels and peripheral insulin sensitivity compared to the artificial cerebrospinal fluid (CSF) group among 90% pancreatectomized (Px) diabetic rats, but not in non-diabetic Sham rats. In addition to short-term infusion, long-term (28 days) central infusion of BHB (12 μg/h) elevated serum BHB levels. Long-term infusion of BHB potentiated leptin and insulin signaling in the hypothalamus to slightly decrease body weight in Px rats. Central BHB infusion had a greater effect on peripheral glucose metabolism than overall energy metabolism. Hepatic insulin signaling (tyrosine phosphorylation of IRS2 → serine phosphorylation of Akt → reduced expression of PEPCK) was potentiated and hepatic glucose production in the hyperinsulinemic state was suppressed in the diabetic rats. In addition, glucose tolerance was improved by central BHB infusion through enhanced whole body glucose disposal rates, but insulin secretion was not affected in the diabetic rats. In conclusion, mild ketosis by central infusion of ketones improves energy and glucose metabolism through the potentiation of leptin and insulin signaling in the hypothalamus of diabetic rats. © 2011 Published by Elsevier B.V.

Objective: There has been no attempt to date to synthesize the available evidence for the efficacy of ginger for treating primary dysmenorrhea. This systematic review evaluates the current evidence for the effectiveness of ginger for treating primary dysmenorrhea. Methods: Literature searches were conducted using 12 electronic databases including PubMed, EMBASE, Cochrane Library, Korean databases, Chinese medical databases, and Indian scientific database. Search terms used were: "ginger" or "Zingiber officinale" and "dysmenorrhea" and "pain." Studies using ginger as a treatment of primary dysmenorrhea were considered for inclusion. The major outcome of primary dysmenorrhea was assessed using a pain visual analogue score (PVAS). Results: Initial searches yielded 29 articles. Of these original results, seven met specific selection criteria. Four of the RCTs compared the therapeutic efficacy of ginger with a placebo during the first 3-4 days of the menstrual cycle and were included in the meta analysis. The meta-analysis of these data showed a significant effect of ginger in reducing PVAS in subjects having primary dysmenorrhea (risk ratio, -1.85; 95% CI of -2.87, -0.84, P=0.0003). Six RCTs out of 7 exhibited low to moderate of risk of bias. Conclusion: Collectively these RCTs provide suggestive evidence for the effectiveness of 750-2000 mg ginger powder during the first 3-4 days of menstrual cycle for primary dysmenorrhea. © 2015 American Academy of Pain Medicine.

Historically, the incidence of type 2 diabetes has been lower in Asian populations compared with those in Western countries. One possible reason for the lower incidence among Asians is that they consume fermented soybean products, which are unique to the traditional Asian diet. Some have hypothesized that dietary phytoestrogens and soy peptides in fermented soybean foods consumed in traditional Asian diets may help prevent and slow the progression of type 2 diabetes. This review evaluates the existing evidence from animal studies and clinical and epidemiologic investigations on fermented soybeans in the prevention and treatment of type 2 diabetes. Nutritional studies performed in animals and intervention studies with humans suggest that the ingestion of soy protein with isoflavones improves glucose control and reduces insulin resistance. Korean fermented soybean products such as doenjang, kochujang, and chungkookjang contain alterations in the structures and content of isoflavonoids and small bioactive peptides, which are produced during fermentation. Several studies revealed improvements in insulin resistance and insulin secretion with the consumption of these fermented products. Therefore, fermented soybean products may help prevent or attenuate the progression of type 2 diabetes. Although the lack of human intervention trials does not permit definitive conclusions, the evidence does suggest that fermented soy products may be better for preventing or delaying the progression of type 2 diabetes compared with nonfermented soybeans. © 2010 Elsevier Inc.

Background: Alzheimer's disease (AD) and type 2 diabetes, two diseases that contribute considerable morbidity and mortality in middle-age and elderly people, coexist and progress in parallel, leading to the presumption that one may cause the other. However, a causative link has not yet been established. Methods: This study used non-diabetic and diabetic rats injected with β-amyloid (25-35) into the CA1 of the hippocampus to induce AD like plaques as a model of early-stage AD to evaluate the effects of AD on energy metabolism. AD like cognitive dysfunction was confirmed using passive avoidance tests and Morris water maze tests. Results: Diabetic and non-diabetic rats with experimental AD exhibited memory deficits by β-amyloid (25-35) accumulation in the hippocampus, but diabetes exacerbated memory impairment. All rats, diabetic and non-diabetic, infused with β-amyloid had profound decreases in energy intake, activity and fat oxidation and increased carbohydrate oxidation and energy expenditure. Energy expenditure was increased by 8-10% and energy intake decreased by approximately 20% in the rats injected with β-amyloid regardless of diabetic status. Conclusions: These results suggest that AD type plaques in the brain may induce metabolic disturbances and cachexia in early AD, which may be an early warning sign of AD in humans. © Springer International Publishing 2014.

Objective.The aim of the study was to retrospectively assess what was the optimal gestational weight gain to have better maternal and neonatal outcomes in overweight and obese Korean women with gestational diabetes mellitus (GDM) who maintained normoglycemia throughout pregnancy by dietary modification, exercise, and/or insulin treatment. Study design.We performed a hospital-based study of 215 GDM women with prepregnancy BMI ≥ 25 kg/m 2. Body weight, glucose homeostasis, lipid profiles, insulin treatment, and maternal outcomes were collected as predictors of neonatal birth weight. We divided the subjects into three groups according to modified Institute of Medicine (IOM) guidelines for weight gain during pregnancy: inadequate (n = 42), normal (n = 96), and excessive (n = 77) groups. Results.Excessive weight gain resulted in increased macrosomia, HbA1c at delivery, and postprandial blood glucose levels, but fasting blood glucose levels were not significantly different among the groups. The inadequate weight gain group (2.4kg weight gain during pregnancy) had better neonatal outcomes and better maternal glycemic control with fewer requiring insulin treatment. Conclusion.Minimal weight gain, well below IOM recommendations, and tight control of blood glucose levels during pregnancy with proper medical management and dietary modification may eliminate most of the adverse pregnancy outcomes experienced by obese GDM Asian women. © 2011 Informa UK, Ltd.

Kimchi is a traditional Korean food manufactured by fermenting vegetables with probiotic lactic acid bacteria (LAB). Many bacteria are involved in the fermentation of kimchi, but LAB become dominant while the putrefactive bacteria are suppressed during salting of baechu cabbage and the fermentation. The addition of other subingredients and formation of fermentation byproducts of LAB promote the fermentation process of LAB to eventually lead to eradication of putrefactive- and pathogenic bacteria, and also increase the functionalities of kimchi. Accordingly, kimchi can be considered a vegetable probiotic food that contributes health benefits in a similar manner as yogurt as a dairy probiotic food. Further, the major ingredients of kimchi are cruciferous vegetables; and other healthy functional foods such as garlic, ginger, red pepper powder, and so on are added to kimchi as subingredients. As all of these ingredients undergo fermentation by LAB, kimchi is regarded as a source of LAB; and the fermentative byproducts from the functional ingredients significantly boost its functionality. Because kimchi is both tasty and highly functional, it is typically served with steamed rice at every Korean meal. Health functionality of kimchi, based upon our research and that of other, includes anticancer, antiobesity, anticonstipation, colorectal health promotion, probiotic properties, cholesterol reduction, fibrolytic effect, antioxidative and antiaging properties, brain health promotion, immune promotion, and skin health promotion. In this review we describe the method of kimchi manufacture, fermentation, health functionalities of kimchi and the probiotic properties of its LAB. © Mary Ann Liebert, Inc. and Korean Society of Food Science and Nutrition 2014.
