The human inducible nitric oxide synthase (hiNOS) gene is regulated by nuclear factor kappaB (NF-kappaB) and has recently been shown to be a target of the Wnt/beta-catenin pathway. In this study, we tested the hypothesis that Wnt/beta-catenin signaling might regulate cytokine- or tumor necrosis factor alpha (TNFalpha)-induced hiNOS expression through… (More)
BACKGROUND Inhibition of inappropriate tyrosine kinase activity by neoplasms is an attractive strategy for the treatment of malignancy. OBJECTIVE We aimed to produce a concise review of the potential role of hepatocyte growth factor (HGF)/Mesenchymal-epithelial transition factor (MET) tyrosine kinase pathway inhibition in the treatment of cancer. … (More)
The hepatocyte growth factor (HGF) receptor c-Met is a tyrosine kinase receptor with established oncogenic properties. We have previously shown that c-Met is usually overexpressed in esophageal adenocarcinoma (EA), yet the implications of c-Met inhibition in EA remain unknown. Three c-Met-overexpressing EA cell lines (Seg-1, Bic-1, and Flo-1) were used to… (More)
Nitric oxide signaling plays complex roles in carcinogenesis, in part, due to incomplete mechanistic understanding. In this study, we investigated our discovery of an inverse correlation in the expression of the inducible nitric oxide synthase (iNOS) and the Wnt/β-catenin regulator Dickkopf-1 (DKK1) in human cancer. In human tumors and animal models,… (More)

INTRODUCTION The CD95/CD95L pathway plays a critical role in tissue homeostasis and immune system regulation; however, the function of this pathway in malignancy remains poorly understood. We hypothesized that CD95L expression in esophageal adenocarcinoma confers advantages to the neoplasm other than immune privilege. METHODS CD95L expression was… (More)
A TBAI (tetrabutylammonium iodide)-catalyzed direct α-oxyacylation of carbonyl compounds from readily available toluene derivatives has been developed. The distinguished features of this metal-free protocol include the employment of simple starting material, a wide carbonyl compound scope, and mild reaction conditions.
A three-component bicyclization reaction of isocyanide, substituted allenoate, and isatin has been disclosed. This protocol is proposed to proceed through Michael addition, double cyclization, and [1,5]-hydride shift sequence, thus leading to the formation of two new rings and five new chemical bonds, including C-C, C-O, and C-N bonds.
An unusual oxidative coupling reaction of isocyanide and toluene derivatives using tetrabutylammonium iodide (TBAI) as a catalyst is disclosed. The experimental results and mechanistic study show that the isocyano group acts formally as an N1 synthon during the transformation, thus expanding the reactivity profile of isocyanide.
