Proteome response to ochratoxin A-induced apoptotic cell death in mouse hippocampal HT22 cells.

Mycotoxins are commonly encountered natural products, and are capable of poisoning animals or humans that inhale mold particles from mycotoxin-contaminated foods. Ochratoxin A (OTA) is produced by Aspergillu ochracus and Penicillium verrucosum, and is often found in cereals and agricultural products. Although previous studies have focused on the potent nephrotoxicity and renal carcinogenicity of OTA, more recent studies suggest that it accumulates in the brain and causes oxidative stress and DNA damage in various brain regions and neuronal populations.
