Functional and ultrastructural effects of essential fatty acid deficiency in kidney epithelial cells

Madin-Darby canine kidney (MDCK) epithelial cells were grown in culture medium supplemented with 1% fetal bovine serum (FBS) to provide a cell culture model of essential fatty acid deficiency (EFAD). 5,8,11-Eicosatrienoic acid (20∶3n−9) accumulated in cellular phospholipids, and arachidonic acid (20∶4) decreased. A large increase in cellular cholesterol… CONTINUE READING
