AIM The role of CYP1A in the protection of aristolochic acid (AA)I-induced nephrotoxicity has been suggested. In the present study we investigated the effects of beta-naphthoflavone (BNF), a non-carcinogen CYP1A inducer, on AAI-induced kidney injury. METHODS Mice were pretreated with 80 mg/kg BNF by daily intraperitoneal injection (ip) for 3 days followed(More)
Autocrine granulocyte macrophage-colony stimulating factor (GM-CSF) sequentially activates intracellular components in monocyte/macrophage production of the pro-inflammatory and immunoregulatory prostanoid, prostaglandin E2 (PGE2). GM-CSF first induces STAT5 signaling protein phosphorylation, then prostaglandin synthase 2 (COX2/PGS2) gene expression, and(More)

Aspergillus versicolor was isolated from the gastric juice of patients with chronic stomach diseases in high-risk area of gastric cancer. Mice fed with aspergillus-inoculated corn flour developed adenocarcinoma of the lung in 15 of 35 mice (42.9%) and atypical hyperplasia of the glandular stomach in 13 of 35 mice (37.4%). Sterigmatocystin was identified by(More)
Aberrant prostaglandin synthase 2 (PGS2/COX2) expression constitutes an antigen presenting cell (APC) dysfunction seen in monocytes of humans at risk for or with Type 1 diabetes. During endotoxin activation of PGS2 expression in healthy monocytes, granulocyte-monocyte colony stimulating factor (GM-CSF) is activated and, in turn, promotes PGS2 gene(More)
Pathological morphology, clinical features and nuclear DNA contents determined by flow cytometry (FCM) were studied in 11 cases of normal adrenals and 41 cases of adrenal neoplasms. It was found that despite differences in clinical manifestations and in degrees of cellular atypia of the adenomas their DNA contents were the same as in normal adrenals. On the(More)
In an attempt to develop potent and selective antitumor agents, a series of 6- and 2-(1-substituted-thio-4-methylpent-3-enyl)-5,8-dimethoxynaphthalene-1,4-diones were designed and synthesized. The cytotoxicities of these compounds were evaluated in vitro against BEL-7402, HT-29 and SPC-A1 cell lines. The pharmacological results showed that most of the(More)
The Yellow Fever (YF) vaccine, an attenuated yellow fever 17D (YF-17D) live vaccine, is one of the most effective and safest vaccines in the world and is regarded as one of the best candidates for viral expression vector. We here first reported in China the construction and characterization of the recombinant expression vector of yellow fever 17D which(More)
To detect the carcinogenicity of sterigmatocystin for human stomach, the human fetal gastric cells, cultured in vitro, were treated with extract solution of Aspergillus versicolor culture (0.117mg sterigmatocystin per Kg culture of Aspergillus versicolor). The cells showed random arrangement, loss of contact inhibition and cell polarity. Some transformed(More)
