    Effects of sterigmatocystin on interleukin-2 secretion of human peripheral blood mononuclear cells in vitro.[Pubmed: 12561545]
    Sterigmatocystin (ST) is one of predominant contaminating mycotoxins in foodstuffs and grains of high incidence areas of malignant tumors in China. The effect of ST on interleukin-2 (IL-2) secretion of human peripheral blood mononuclear cells (HPBMc) in vitro was determined with enzyme-linked immunosorbent assay (ELISA) method to explore its putative effects on human immune function. ELISA analysis revealed that ST treatment generally showed negative effects on the IL-2 secretion of HPBMc in vitro. As the ST concentration changes, the inhibiting effects were different. The inhibiting effects at low concentrations (0.03125-0.125 mg/L) and high concentrations (1-2 mg/L) were stronger than the other concentrations(P < 0.05). The time-effect analysis (ST 1 mg/L) showed that inhibiting effects of ST on IL-2 secretion of HPBMc could be seen to a variable degree from 1 to 64 h after ST treatment, while a significant time-effect correlation could be found from 8 to 64 h (r = 0.822, P < 0.05). The results obtained in present study showed that ST has certain inhibiting effects on the secretion of IL-2 of HPBMc in vitro.

    Involvement of MAPK and PI3K signaling pathway in sterigmatocystin-induced G2 phase arrest in human gastric epithelium cells.[Pubmed: 21287681]
    Sterigmatocystin (ST), a mycotoxin commonly found in foodstuff and feedstuff, has been shown to be a carcinogenic mycotoxin in animal models. Many studies showed that the high level of ST contamination in grains might be related to the high incidence of gastric carcinoma in rural areas of China. However, up to now, the potential effects of ST on human gastric epithelium cells remain largely unknown. In this study, we explored the effects of ST on cell-cycle distribution and the regulatory mechanism in immortalized human gastric epithelium cells (GES-1). This study demonstrates that JNK, ERK and PI3K/AKT/mTOR pathways participated in the G2 arrest induced by ST through the deregulation of CyclinB1, Cdc2 and Cdc25C. It may play some roles in the gastric carcinogenesis in ST exposure populations.

    Sterigmatocystin: occurrence in foodstuffs and analytical methods--an overview.[Pubmed: 19998385]
    Sterigmatocystin (STC) is a mycotoxin produced by fungi of many different Aspergillus species. Other species such as Bipolaris, Chaetomium, Emiricella are also able to produce STC. STC producing fungi were frequently isolated from different foodstuffs, while STC was regularly detected in grains, corn, bread, cheese, spices, coffee beans, soybeans, pistachio nuts, animal feed and silage. STC shows different toxicological, mutagenic and carcinogenic effects in animals and has been recognized as a 2B carcinogen (possible human carcinogen) by International Agency for Research on Cancer. There are more than 775 publications available in Scopus (and more than 505 in PubMed) mentioning STC, but there is no summary information available about STC occurrence and analysis in food. This review presents an overview of the worldwide information on the occurrence of STC in different foodstuffs during the last 40 years, and describes the progress made in analytical methodology for the determination of STC in food.

    Cytotoxic and mutagenic effects of sterigmatocystin on cultured Chinese hamster cells.[Pubmed: 7296761]
    Cytotoxic and mutagenic effect of Sterigmatocystin (STC), a carcinogenic mycotoxin, on cultured Chinese hamster cells were investigated in the presence or absence of a metabolic activation system. STC directly applied to the cells induced cytotoxicity and drug-resistant mutations in a time- and concentration-dependent manner. Analyses of the effects of STC showed that treatment for shorter periods was more effective than that for longer periods. The presence of an activation system, cytotoxic and mutagenic effects of STC were strongly enhanced, and 1% of the microsome fraction was most efficient in inducing the effects. Analyses by equitoxic comparison showed that there was little difference in mutagenic activity between the direct treatment and the treatment using an activation system.
