Ginsenoside Rb1 can ameliorate the key inflammatory cytokines TNF-? and IL-6 in a cancer cachexia mouse model.

ABSTRACT: BACKGROUND:Cancer cachexia is a severe condition that leads to the death of advanced cancer patients, and approximately 50~80% of cancer patients have cancer cachexia. Ginseng extract has been reported to have substantial anticancer and immune-enhancing effects; however, no study has reported the use of ginseng alone to treat cancer cachexia. Our study's purpose was to investigate the therapeutic effects of ginseng-related monomers or mixtures on a cancer cachexia mouse model. METHODS:We selected BALB/c mice and injected the mice subcutaneously with C26 colon cancer cells to construct a cancer cachexia experimental animal model. The water extract of ginseng (WEG), two types of ginseng extracts (ginsenosides at doses of 5?mg/kg (GE5) and 50?mg/kg (GE50)) and ginsenoside Rb1 (Rb1) were used to treat cancer cachexia mice. Enzyme-linked immunosorbent assays (ELISAs) were used to analyze the inhibitory effects on two key inflammatory cytokines, tumor necrosis factor-? (TNF-?) and interleukin-6 (IL-6). RESULTS:Our experimental results show that GE5, GE50 and Rb1 significantly reduced the levels of TNF-? (P?

Project description:Diabetes mellitus is a common global health problem. Among the complications that are frequently associated with DM are the alternation of sexual function and fertility, especially in young men. This study aimed to assess the efficacy of nanoparticles of Costus speciosus (C. speciosus) in preserving the prostatic structure of diabetic rats and to explore the mechanism behind this effect. A model of DM was induced in male albino rats by a single intraperitoneally injection of streptozotocin (STZ, 60 mg/kg body weight). Five groups (n = 10 each) of rats were included in this study: the control, C. speciosus gold nanoparticles-treated (150 mg/kg body weight through gastric intubation for 30 days), untreated diabetic, metformin-treated diabetic (500 mg/kg/day gastric intubation for 30 days) and the C. speciosus-treated diabetic group. The blood glucose, insulin and testosterone levels as well as oxidants/antioxidants status were assessed in the serum. Gene expression of proinflammatory cytokines TNF-α, IL1β and IL-6 were assessed in the prostate homogenate. At the end of the experiment, the rats were sacrificed and the prostate was dissected out and prepared for histopathological and immunohistochemistry study using Ki67 and Bcl-2. C. Speciosus nanoparticles significantly decreased (p = 0.03) the blood glucose level while significantly increasing insulin (p = 0.01) and testosterone (p = 0.04) levels compared to the untreated diabetic rats. Oxidants/antioxidants status was markedly improved after administration of C. speciosus. Prostatic expression of the mRNA of pro-inflammatory cytokines IL-6, IL1β and TNF-α was down-regulated in metformin- and C. speciosus-treated rats. The histological structure of the ventral prostate was preserved in metformin- and C. speciosus-treated diabetic rats with a significantly thicker epithelial cell layer and significant increase immunoexpression in Bcl-2 and Ki67. In conclusion, the protective effect induced by C. speciosus nanoparticles on the prostate of diabetic rats might be directly mediated through the down-regulation of inflammatory cytokines and the up-regulation of antioxidant activity and indirectly mediated through the anti-hyperglycemic effect through enhancing insulin secretion.
