Scope: Obesity and metabolic diseases are closely associated, and individuals who become obese are also prone to type 2 diabetes and cardiovascular disorders. Gut microbiota is mediated by diet and can influence host metabolism and the incidence of metabolic disorders. Recent studies have suggested that improving gut microbiota through a fructooligosaccharide (FOS)-supplemented diet may ameliorate obesity and other metabolic disorders.

Fermented foods demonstrate remarkable health benefits owing to probiotic bacteria or microproducts produced via bacterial fermentation. Fermented foods are produced by the fermentative action of several lactic acid bacteria, including ; however, the exact mechanism of action of these foods remains unclear. Here, we observed that prebiotics associated with -produced exopolysaccharides (EPS) demonstrate substantial host metabolic benefits.

Due to the excess energy intake, which is a result of a high fat and high carbohydrate diet, dysfunction of energy balance leads to metabolic disorders such as obesity and type II diabetes mellitus (T2DM). Since obesity can be a risk factor for various diseases, including T2DM, hypertension, hyperlipidemia, and metabolic syndrome, novel prevention and treatment are expected. Moreover, host diseases linked to metabolic disorders are associated with changes in gut microbiota profile.

Development of chemotherapy has led to a high survival rate of cancer patients; however, the severe side effects of anticancer drugs, including organ hypoplasia, persist. To assume the side effect of anticancer drugs, we established a new ex vivo screening model and described a method for suppressing side effects. Cyclophosphamide (CPA) is a commonly used anticancer drug and causes severe side effects in developing organs with intensive proliferation, including the teeth and hair.

Transient receptor potential ankyrin 1 (TRPA1) is activated by noxious cold, mechanical stimulation, and irritant chemicals. In our recent study, 9, 10-phenanthrenequinone (9,10-PQ) is the most potent irritant for activation of NRF2 among 1395 cigarette smoke components and it may be, therefore, important to find its additional targets. Here, we show that 9,10-PQ functions as an activator of TRPA1 in human embryonic kidney (HEK) cells expressing human wild-type TRPA1 (HEK-wTRPA1) and human alveolar A549 (A549) cells.
