Inorganic arsenic species are potent environmental toxins and causes of numerous health problems. Most studies have assumed that arsenic-induced changes in mRNA levels result from effects on gene transcription. We evaluated the prevalence of changes in mRNA stability in response

Coastal environments worldwide are threatened by the effects of pollution, a risk particularly high in semienclosed basins like the Mediterranean Sea that is poorly studied from bioremediation potential perspective especially in the Southern coast. Here, we investigated the physical, chemical

Sodium arsenite induces apoptosis in PC12 cells by activating the stress-activated p38 MAP kinase and the pro-apoptotic Bcl-2 family protein Bim(EL). However, the relationship between p38 and Bim(EL) in this apoptosis has not been fully defined. Here, we report that

Rodent models have been extensively utilized to identify putative human immunotoxicants; however, even when immunotoxicity is established, uncertainty remains whether the effects are predictive of human risk. Therefore, the objective of this study was to establish a polyclonal immunoglobulin M
