Application
Ochratoxin A has been used as a mycotoxin:
- to test its effect on metabolism and hypoxia in human embryonic kidney (HEK293) cells[1]
- to test its cytotoxic effects in bovine mammary epithelial cells[2]
- as a standard for gamma radiation studies with food products and in cytotoxic studies using Hep G2 cells[3]
Actions biochimiques/physiologiques
Ochratoxin A (OTA), a renal toxin, is produced majorly by Aspergillus and Penicillium fungal species.[1] It is immunotoxic, teratogenic[2] myelotoxic, and mutagenic.[3] It effectively interrupts the intestinal barrier functions.[2] OTA displays a long elimination half-life[3] and stimulates the major inflammatory cytokines release.[2]
Ochratoxin A is a mycotoxin found in food that is nephrotoxic and carcinogenic in the kidney and induces differentiation in cloned renal cell lines. Increases endoplasmic reticulum ATP-dependent Ca2+ pump activity.
