Ochratoxin A (OTA) is a fungal metabolite with controversial immunomodulatory effects. A prolonged in vivo exposure to the mycotoxin may result in impaired immunity and decreased resistance to infections. In the present study, OTA modulation of lipopolysaccharide (LPS)-induced inflammatory process
Eosinophilic chronic rhinosinusitis (ECRS) largely consists of allergic fungal sinusitis, non-allergic fungal rhinosinusitis, aspirin-exacerbated ECRS, and superantigen-induced ECRS. The pathophysiology of ECRS is not completely understood, in particular, the role of mycotoxins remains unknown. The
Ochratoxin A (OTA) and aristolochic acid (AA) are toxins that can frequently contaminate cereals and cereals-based products. The present study has realized a comparison between the effect of OTA and AA on oxidative stress and inflammation in both the liver and kidney of pigs as major organs involved
Ochratoxin A (OTA) is a secondary metabolite produced by fungi of Aspergillus and Penicillium genra. OTA is mainly nephrotoxic but can also cause hepatotoxicity, mutagenicity, teratogenicity, neurotoxicity and immunotoxicity. As recent studies have highlighted the close relationship between
Ochratoxin A (OTA) is a widespread mycotoxin and induces liver inflammation to human and various species of animals. The intestinal microbiota has critical importance in liver inflammation; however, it remains to know whether intestinal microbiota mediates the liver inflammation Ochratoxin A (OTA), a common contaminant of grain and fruit and known carcinogen, has been linked to impaired antioxidant response and cellular repair. The effect of OTA on inflammation in cells has not been explored. This study investigated OTA's influence on inflammatory mediators using a range of
Cytotoxicity of ochratoxin A (OTA) was evaluated using the MTS assay, and membrane integrity was measured using transepithelial electrical resistance (TEER). A transwell system was used to investigate the effect of OTA on the expression of the CYP450 (1A1, 2A6, 2B6, 3A4 and 3A5), NAT2, COX-2, LOX-5,
Nephrotoxicity and hepatotoxicity induced by Ochratoxin A (OTA) and ameliorating effects of melatonin were investigated in rats exposed to OTA. Experimental groups were as follows: control; OTA-treated; and OTA plus melatonin (MEL)-treated (OTA+MEL). The rats in the control group were administered
Ochratoxin A (OTA) is a mycotoxin produced by different fungi. The most pronounced adverse effect of OTA is hepatonephrotoxicity. Melatonin (MEL) has an antioxidant effect and has free-radical scavenger properties. The effects of OTA on heart and lung tissue and possible ameliorating effects of MEL
(1) Background: Impaired adipose tissue function leads to the development of metabolic disorders. Reactive oxygen species play a key role in the regulation of adipogenesis and insulin-stimulated glucose uptake by adipocytes. Quercetin (QCT) regulates adipogenesis by affecting the redox state of
The mycotoxin ochratoxin A (OTA), an ubiquitous contaminant of food products endowed with a wide spectrum of toxicity, affects several functions of mononuclear leukocytes. Monocytes/macrophages play a major role in fibrin accumulation associated with immune-inflammatory processes through the
Recent findings have suggested that oxidative damage might contribute to the cytotoxicity and carcinogenicity of aflatoxin B(1) (AFB(1)). The induction of oxidative stress also plays an important role in the toxicity of another mycotoxin: ochratoxin A (OTA). In this study, the protective effect of
Ochratoxin A (OTA) is a mycotoxin involved in the development of chronic nephropathies and a known carcinogen. As we have shown previously, OTA activates mitogen-activated protein kinases [extracellular signal-regulated kinase 1 and 2 (ERK1/2), c-jun amino-terminal kinase (JNK), and
Ochratoxin A (OTA) is a mycotoxin that contaminates cereals and animal feed and causes nephropathy to a variety of animal species. OTA is also known as a potent immunotoxic, teratogenic, and carcinogenic mycotoxin. In addition, OTA ingestion induces intestinal injuries, including inflammation and
The practice of replacing costly animal-derived proteins with more economical plant proteins has augmented the risk of mycotoxin contamination in fish feeds, including contamination with ochratoxin A (OTA). OTA is a secondary metabolite produced by molds commonly found in fish feeds that causes
