Within the central nervous system and under normal conditions, nitric oxide (NO) is an important physiological signaling molecule. When produced in large excess, NO also displays neurotoxicity. In our previous report, we have demonstrated that the exposure of neuronal cells to NO donors induced apoptotic cell death, while pretreatment with free radical(More)
Betanodaviruses, members of the Nodaviridae family, are the causative agents of viral nervous necrosis in fish and infection by which cause high mortality in larvae and juveniles in a wide range of marine fish species in Asia, Europe, Australia, Martinique, and Tahit. Greasy grouper (Epinephelus tauvina) nervous necrosis viruses (GGNNV) were investigated(More)
Cellular proteins have been implicated as important for HIV-1 reverse transcription, but whether any are reverse transcription complex (RTC) cofactors or affect reverse transcription indirectly is unclear. Here we used protein fractionation combined with an endogenous reverse transcription assay to identify cellular proteins that stimulated late steps of(More)
Taurine upregulated gene1 (TUG1) as a 7.1-kb lncRNA, has been shown to play an oncogenic role in various cancers. However, the biological functions of lncRNA TUG1 in small cell lung cancer (SCLC) remain unknown. The aim of this study is to explore the roles of TUG1 in cell growth and chemoresistance of SCLC and its possible molecular mechanism. The(More)
Scavenging effects of L-ascorbic acid 2-[3,4-dihydro-2,5,7,8- tetramethyl-2-(4,8,12-trimethytridecyl)-2H-1-benzopyran- 6-yl-hydrogen phosphate] potassium salt (EPC-K1) on hydroxyl radicals, alkyl radicals and lipid radicals were studied with ESR spin trapping techniques. The inhibition effects of EPC-K1 on lipid peroxidation were assessed by TBA assay. The(More)
BACKGROUND Experimental models of human infantile hemangiomas are needed, although none of the current ones is ideal in representing the natural development of hemangioma. In this article, the authors present a nude mice model of human hemangioma with serial morphologic findings on grafts. METHODS A specimen of rapidly growing hemangioma tissue was(More)
To investigate the role of N-acetylglucosaminyltransferases V (GnT-V) in the malignancy of human hepatocellular carcinoma (HCC), the GnT-V stably suppressed cell line HepG2 GnT-V/1564 was constructed from HepG2. The proliferation, migration, invasion, metastasis of HepG2 GnT-V/1564 was investigated both in vitro and in vivo. The clinical pathological(More)
The ability of oxidative stress to induce apoptosis and the protective effects of Ginkgo biloba extract (EGb761) against this induction were studied in cultures of rat cerebellar granule cells. Cells were exposed to oxidative stress by treatment with 50 microm hydrogen peroxide+100 microm ferrous sulphate which generates hydroxyl radicals by Fenton(More)
Two generic PCR protocols were developed to detect nepoviruses in subgroups A and B using degenerate primers designed to amplify part of the RNA-dependent RNA polymerase (RdRp) gene. It was observed that detection sensitivity and specificity could be improved by adding a 12-bp non-complementary sequence to the 5' termini of the forward, but not the reverse,(More)
The genome sequence of tomato ringspot virus (ToRSV, a subgroup C nepovirus) is currently available for one raspberry isolate. In this study, we describe the complete genome sequence of three additional isolates from raspberry (Rasp1-2014), grapevine (GYV-2014) and prunus (13C280). The degree of nucleotide sequence identity shared between RNA1 and RNA2 in(More)
