pubmed:abstractText |
Fetal calf serum is able to activate arachidonic acid release from phospholipids in NRK 49F cells. We showed that this phenomenon can be potentiated by adding oxysterols to the culture medium. The oxysterol effect was dose-dependent and was not observed in the absence of fetal calf serum. Greater amounts of prostaglandin E2 and prostaglandin F2 alpha were released into the medium in the presence of oxysterols without apparent modification of the cyclooxygenase activity. The most effective oxysterols, in descending order, were the following: calcitriol greater than 7 alpha-hydroxycholesterol greater than 7 beta-hydroxycholesterol greater than 25-hydroxycholesterol. Cholesterol and 7-ketocholesterol were unable to activate phospholipase activity. The mechanism of this activation by oxysterols is still unknown.
