F10, a new camptothecin derivative, was identified as a new orally-bioavailable, potent antitumor agent.

Topoisomerases are interesting targets for drug discovery. In the present study, we attached saturated carbon atoms to the 10-position of camptothecin and synthesized 10 new camptothecin derivatives from 10-HCPT or SN-38. The activities of new compounds were evaluated both in vitro and in vivo.

Loganetin protects against rhabdomyolysis-induced acute kidney injury by modulating the toll-like receptor 4 signalling pathway.

Background And Purpose: Acute kidney injury (AKI) is a rapid renal dysfunctional disease, for which no effective drugs or therapies are available to improve prognosis. Loganetin is a natural product with unknown bioactivities. Here, we identified a new protective effect and mechanism of Loganetin in a mouse model of AKI induced by rhabdomyolysis.

Association of polymorphisms of adiponectin gene promoter-11377C/G, glutathione peroxidase-1 gene C594T, and cigarette smoking in nonalcoholic fatty liver disease.

Background: The number of studies on adiponectin, GPx-1 gene polymorphisms, and nonalcoholic fatty liver disease (NAFLD) susceptibility is increasing, but none have investigated the effect of cigarette smoking in combination with the gene polymorphisms on the susceptibility to NAFLD. In order to understand the distribution of adiponectin and GPx-1 in the local population, to explore the possible association of cigarette smoking with adiponectin and GPx-1 gene polymorphisms in the pathogenesis of NAFLD, we conducted this research, examining the distribution of polymorphisms of adiponectin and GPx-1 in NAFLD patients and healthy controls, analyzing the association between these polymorphisms and cigarette smoking.

Methods: Two hundred nonalcoholic simple fatty liver (NAFL), 200 nonalcoholic steatohepatitis (NASH), and 200 nonalcoholic fatty hepatic cirrhosis (NAFHC) cases from the First Affiliated Hospital of Xinxiang Medical College in China from February 2011 to November 2014 were selected for this study, and 200 healthy individuals as a control group.

Interaction of Polymorphisms of Resistin Gene Promoter -420C/G, Glutathione Peroxidase -1 Gene Pro198Leu and Cigarette Smoking in Nonalcoholic Fatty Liver Disease.

Background: Many studies have suggested that cigarette smoking and polymorphisms of resistin and glutathione peroxidase-1 (GPx-1) genes are closely correlated with the pathogenesis of nonalcoholic fatty liver disease (NAFLD). However, few reports have investigated these associations with respect to NAFLD susceptibility. We, therefore, examined the distribution of polymorphisms in GPx-1 and resistin genes in NAFLD patients and healthy controls and analyzed the relationship between these polymorphisms and smoking status.

The chemokine-like factor 1 induces asthmatic pathological change by activating nuclear factor-κB signaling pathway.

CKLF1, which exhibits chemotactic activities on a wide spectrum of leukocytes, is up-regulated during the progress of asthma. It plays a vital role in the pathogenesis of pulmonary disease. Here, we report that CKLF1 has the capability to activate the NF-κB signaling pathway leading to the pathological change in the lung.

Stereospecific analysis of triacylglycerol and phospholipid fractions of five wild freshwater fish from Poyang Lake.

The fatty acids (FA) compositions and positional distributions in triacylglycerols (TAG) and phospholipids (PL) of five wild freshwater fish (Squaliobarbus curriculus, Erythroculter ilishaeformis, Pseudobagrus fulvidraco, Bostrichthys sinensis, and Siniperca kneri Garman) from Poyang Lake (the largest freshwater lake of China) were studied. For TAG, S. kneri German had the highest content (13.

[Effect of testosterone on the expression of CMTM family of the male spermatogenesis suppression rats].

This study is to investigate the influence and the expression of CMTM family of testosterone on spermatogenesis suppression in the male rats treated by gossypol and cyclophosphamide. Gossypol (50 mg kg(-1)) and cyclophosphamide (20 mg kg(-1)) were administered to male rats to induce spermatogenesis suppression. Testosterone propionate was administrated at the dose of 5 mg kg(-1) every other day for 6 times.
