INTRODUCTION Hydrogen sulfide (H(2) S) is generated in mammalian cells mainly by one of the two pyridoxal-5'-phosphate-dependent enzymes, cystathione-γ-lyase (CSE), and cystathione-β-synthase (CBS) using L-cysteine as the main substrate. In previous studies, we found that CBS and CSE were functionally expressed in vas deferens (VD) and H(2) S-mediated VD… (More)
Cystathionine-lyase and cystathionine-synthase, both H(2)S-synthesizing enzymes, were functionally expressed in the vas deferens of rat, mice, and human. Endogenous H(2)S mediated vas deferens smooth muscle relaxation.
Major histocompatibility complex class I-related chains A (MICA), a ligand of Natural killer group 2, member D (NKG2D) receptor, is broadly upregulated in epithelial originated tumor cells. MICA plays a critical role in the immune surveillance against tumor cells and is associated with the prognosis of several malignancies. The aim of this study is to… (More)
The aim of this study is to investigate the clinical significance of hypoxia inducible factor-1α (HIF-1α) expression in esophageal squamous cell cancer (ESCC) and clarify the effects of PX-478, a selective HIF-1α inhibitor, on ESCC both in vitro and in vivo. HIF-1α, cyclooxygenase-2 (COX-2) and programmed death ligand-1 (PD-L1) were markedly overexpressed… (More)
Renal cell carcinoma (RCC) is the most lethal of all genitourinary malignancies. Distant metastasis represents the major cause of death in patients with RCC. Recent studies have implicated the AAA+ ATPase pontin in many cellular activities that are highly relevant to carcinogenesis. In this study, we demonstrate for the first time that pontin was… (More)
