Abstract
Apoptosis induction in renal epithelial cells caused by exposure to ochratoxin A (OTA) was studied. Nanomolar concentrations of OTA led to activation of caspase 3 with subsequent chromatin condensation and DNA ladder formation, both characteristic for cells undergoing apoptosis. Inhibition of the mitochondrial ATP/ADP carrier prevented OTA induced caspase activation showing that intact mitochondria are necessary for OTA induced apoptosis. Die Wirkung von Ochratoxin A auf kultivierte renale Epithelzellen in bezug auf Induktion der Apoptose wurde untersucht. Ochratoxin A Exposition im nanomolaren Bereich führt zu Caspasen Aktivierung mit nachfolgender Apoptose der Zellen. Intakte, ATP-produzierende Mitochondrien sind notwendig zur Aktivierung der Caspase 3 durch OTA Exposition.Keywords
