Fumonisin B1 (FB1), mainly produced by Fusarium verticillioides and Fusarium proliferatum, can be converted to the less toxic metabolite hydrolyzed FB1 (HFB1) by enzymatic degradation. The application of an FB1degrading enzyme as a feed additive
Fumonisins, a family of mycotoxins, are mainly toxic and carcinogenic. The present study was carried out to evaluate fumonisin B1 (FB1) effects on the production of inflammatory cytokines by gastric and colon cell lines. The study was performed on two cell lines under in vitro condition, including
Fumonisin B(1) (FB(1)) produces species-specific and organ-specific toxicity, including equine leukoencephalomalacia, porcine pulmonary edema, and hepatic or renal damage in other animals. FB(1) causes inhibition of ceramide synthase, leading to accumulation of free sphingoid bases. We previously
Ceramide is a sphingolipid with potent proinflammatory and proapoptotic properties. This study sought to determine whether pharmacological inhibition of ceramide biosynthesis in the intestine attenuates pathophysiological sequelae of shock induced by splanchnic artery occlusion and reperfusion.
Fumonisin B1 (FB1), a mycotoxin, is a potent inhibitor of ceramide synthase, and produces organ-, species-, and even gender-specific toxic responses in animals. The hepatotoxic response of FB1 in mice involves accumulation of free sphingoid bases and induction of inflammatory cytokines including
A total of 390 one-day-old quail chicks (Coturnix coturnix japonica) were divided into 4 groups (3 replicates per treatment), viz. CX, FX, MX, and FM, containing 75, 105, 105, and 105 birds, respectively. Birds in the control group (CX) were fed quail mash alone, whereas birds in group FX were fed
Ceramide has emerged as an important lipid messenger for many cellular processes triggered via surface receptors. In the present study, inflammatory activation of P388D1 macrophages with bacterial lipopolysaccharide (LPS) and platelet-activating factor (PAF) stimulated a transient accumulation of
Activation of mitogen-activated protein kinase (MAPK) results in pleiotropic effects such as modulation of the transcription and activation of enzymes involved in signal transduction. One such enzyme is the cytoplasmic phospholipase A(2) (cPLA(2)), which releases arachidonic acid (AA). AA is the
Fumonisin B1 (FB1) is a water-soluble fungal metabolite that elicits a wide spectrum of toxicological effects. Cellular targets of FB1 include immune cells and in particular macrophages. In the present study the cytotoxic effect of FB1 (1-100 microM) was evaluated using a murine macrophage cell line
In Hungary almost 70% of mould-affected maize inspected since 1993 was found to be contaminated with fumonisin B1 (FB1) (mean 2.6-8.65 mg/kg; maximum 9.8-75.1 mg/kg), the degree of this contamination was found to increase from year to year (Fazekas et al., 1997b). In this experiment, in order to
Fumonisin B1 (FB1), a congener of fumonisins produced by Fusarium species, is the most abundant and most toxicologically active fumonisin. FB1 causes severe mycotoxicosis in animals, including nephrotoxicity, hepatotoxicity, and disruption of the intestinal barrier. However, mechanisms associated
Interaction between adipocytes and macrophages has been suggested to play a central role in the pathogenesis of obesity. Ceramide, a sphingolipid de novo synthesized from palmitate, is known to stimulate pro-inflammatory cytokine secretion from multiple types of cells. To clarify whether de novo
Recent studies have suggested that inhalation of diesel exhaust (DE), a major source of air pollution, results in pulmonary alterations; however, the effects of DE at low concentrations are poorly understood. Therefore, this study was conducted to elucidate the pulmonary effects of low-level
Ceramide is a major proapoptotic mediator released in response to numerous stimuli, including oxidative stress and cytokines. The role of ceramide in the pathophysiology of inflammation is just emerging, and the potential relevance of this pathway in nonseptic shock is not known. The aim of this
Ceramides contribute to obesity-linked insulin resistance and inflammation in vivo, but whether this is a cell-autonomous phenomenon is debated, particularly in muscle, which dictates whole-body glucose uptake. We comprehensively analyzed lipid species produced in response to fatty acids and
