Study on the Apoptosis Mechanism Induced by T-2 Toxin
T-2 toxin is known to induce apoptosis in mammalian cells. The mechanism of apoptosis induced by T-2 toxin has been proposed to be linked with oxidative stress and mitochondrial pathway. In the current study, the toxic effect of T-2 on Hela, Bel-7402, and Chang liver cells was examined in dose-dependent and time-dependent manner by MTT assay. Caspase-3 was found to be up-regulated under T-2 tox...
متن کاملEffects of T-2 Toxin on Cytokine Produc-tion by Mice Peritoneal Macrophages and Lymph Node T-Cells
Background: T-2 toxin is a mycotoxin of type A trichothecenes produced by several fungal genera such as Fusarium species. Mycotoxins can affect both cell mediated and humoral immune compartments. Objective: The purpose of this study was to investi-gate the effect of T-2 toxin on cytokine production by mouse peritoneal macrophages and lymph node T cells. Methods: Mouse peritoneal macrophages and...
متن کاملAssay and relationship of HT-2 toxin and T-2 toxin formation in liquid culture.
Both T-2 toxin and HT-2 toxin can be conveniently quantitated in crude extracts by using a combination of thin-layer chromatography and fluorodensitometry. This technique was used to follow the production of these toxins by liquid cultures of Fusarium poae (NRRL 3287). T-2 toxin was produced prior to HT-2 toxin and hexadeuterio-T-2 toxin was converted by the culture to trideuterio-HT-2 toxin.
متن کاملApoptosis in the developing mouse embryos from T-2 toxin-inoculated dams.
T-2 toxin (3 mg/kg b.w.) was orally inoculated to pregnant mice at 11 days of gestation to examine the effect of T-2 toxin on the developing embryos. At 24 hours after T-2 toxin-inoculation, moderate pyknosis or karyorrhexis was generally observed in some layers of the central nervous system, caudal sclerotomic segment, caudal region of the tongue to pharyngeal- to laryngeal-mesenchyma, trachea...
متن کاملThe Role of Mitochondria in T-2 Toxin-Induced Human Chondrocytes Apoptosis
T-2 toxin, a mycotoxin produced by Fusarium species, has been shown to cause diverse toxic effects in animals and is also a possible pathogenic factor of Kashin-Beck disease (KBD). The role of mitochondria in KBD is recognized in our recent research. The aim of this study was to evaluate the role of mitochondria in T-2 toxin-induced human chondrocytes apoptosis to understand the pathogenesis of...
