Tracking the distribution of stem cells is crucial to their therapeutic use. However, the usage of current vectors in cellular labeling is restricted by their low internalizing efficiency. Here, we reported a cellular labeling approach with a novel vector composed of mesoporous silica nanoparticles (MSNs) conjugated with fluorescein isothiocyanate in human bone marrow mesenchymal stem cells and...

Insulin stimulates glucose transport in adipocytes via the rapid redistribution of the GLUT1 and GLUT4 glucose transporters from intracellular membrane compartments to the cell surface. Insulin sensitivity is dependent on the proper intracellular trafficking of the glucose transporters in the basal state. The bulk of insulin-sensitive transport in adipocytes appears to be due to the translocati...

Raspberry ketone (RK) is a natural phenolic compound of the red raspberry. The dietary administration of RK to male mice has been reported to prevent high-fat diet-induced elevation in body weight and to increase lipolysis in white adipocytes. To elucidate a possible mechanism for the antiobesity action of RK, its effects on the expression and the secretion of adiponectin, lipolysis, and fatty ...

Abnormal lipid metabolism in adipose tissue is closely related to the occurrence and progression of a wide variety of metabolic syndromes. We have analyzed the pharmacological effects of Chinese herbal medicines on cell differentiation and lipid metabolism in adipocytes. Yi-Gan-San (YGS) is a Chinese herbal medicine that is effective in treating the behavioral and psychological symptoms of deme...

Adipocyte differentiation and the extent of subsequent fat accumulation are closely related to the occurrence and progression of diseases such as insulin resistance and obesity. Black soybean koji (BSK) is produced by the fermentation of black soybean with Aspergilllus awamori. Previous study indicated that BSK extract has antioxidative and multifunctional bioactivities, however, the role of BS...

Tumor necrosis factor α (TNFα) is a well-known mediator of inflammation in the context of obesity in adipose tissue. Its action appears to be directly linked to perturbations of the insulin pathway, leading to the development of insulin resistance. Visfatin has been suspected to be linked to insulin sensitivity, but the mechanism involved is still partly unknown. The aim of this study was to ev...

Mushrooms have been used to treat various diseases for thousands of years. In the present study, the effects of Pleurotus sajor-caju mushroom on lipogenesis, lipolysis and oxidative stress in 3T3-L1 cells were investigated. The β-glucan-rich polysaccharides (GE) from P. sajor-caju stimulated lipogenesis and lipolysis but attenuated protein carbonyl and lipid hydroperoxide levels in 3T3-L1 cells...

BACKGROUND Bis-(2-ethylhexyl) tetrabromophthalate (TBPH) is widely used as a replacement for polybrominated diphenyl ethers (PBDEs) in commercial flame retardant mixtures such as Firemaster 550. It is also used in a commercial mixture called DP 45. Mono-(2-ethyhexyl) tetrabromophthalate (TBMEHP) is a potentially toxic metabolite. OBJECTIVES We used in vitro and rodent in vivo models to evalua...

Breast cancer is one of the most common cancers in women worldwide. The obesity process is normally accompanied by chronic, low-grade inflammation. Infiltration by inflammatory cytokines and immune cells provides a favorable microenvironment for tumor growth, migration, and metastasis. Epidemiological evidence has shown that aspirin is an effective agent against several types of cancer. The aim...
