Dioscin has been shown to promote anticancer activity against several forms of cancers. However, its detailed molecular mechanisms have not clarified. In this study, we demonstrate that dioscin induces apoptosis in cancer cells through the induction oxidative stress. Treatment with vitro resulted rapid generation reactive oxygen species (ROS) and mitochondrial pathway human esophageal cell line Kyse510. Inhibition stress by antioxidant N-acetylcysteine blocked dioscin, indicating ROS is...

In this study, we investigated the protective effect and mechanism of curcumin on a rat model intestinal ischemia/reperfusion (I/R), which induces an acute liver lesion.Curcumin was injected into rats in groups through left femoral vein. The same volume vehicle (0.9% normal saline) sham I/R groups. Blood tissue were gathered for serological histopathological determination.Intestinal led to severe injury manifested as significant increase serum AST ALT levels; all those reduced by treatment...

The antitumor antibiotics radicicol and geldanamycin are potent inhibitors of the Hsp90 protein folding machinery. Radester is a hybrid composed radicicol's resorcinol ring geldanamycin's quinone through an isopropyl ester. was prepared, cytotoxicity it corresponding hydroquinone were determined in MCF-7 breast cancer cells to be 13.9 7.1 μM, respectively. Protein degradation assays performed on Hsp90-dependent client proteins, Her-2 Raf, correlate inhibition cytotoxicity.

DNA monolayers are widely used in fundamental and applied genomics versatile experimental models for elucidating the behavior of charged polymers at interfaces. The physical these systems is to a large extent governed by their internal ionic microenvironment, which investigated here layers end-tethered, single-stranded oligonucleotides (DNA brushes). Retention counterions brush manifests as lowered susceptibility interfacial capacitance external salt conditions. A model based on concepts...

Sphingosine kinases (SphK), including SphK1 and SphK2, are important enzymes promoting progression of prostate cancer. SKI-178 is a novel highly potent SphK1/2 dual inhibitor. We here tested the potential anti-prostate cancer cell activity SKI-178. Bioinformatics analyses results from local tissues demonstrated that both SphK2 upregulated in human tissues. Ectopic overexpression by lentiviral constructs, promoted primary proliferation migration. In cells immortalized lines, potently...

Biological assays often rely on “reporter labels” to enhance measurement sensitivity, for example, by incorporation of a fluorescent dye or nanoparticle into nucleic acid protein. Use labels, however, complicates sample preparation, increases assay costs, and can cause experimental artifacts interfering with thermodynamics limiting label stability. We evaluate near-field microwave imaging (NFMI) as an alternative, label-free technique molecular diagnostics. Using DNA monolayers model, NFMI...
