Prostaglandin synthesis in dental cysts

The synthesis of prostaglandins by dental squamous cell cysts was studied. Radiothinlayer-chromatography (RTLC) showed C14-labelled arachidonic acid to be converted into the prostaglandins PGE2, 6-oxo-PGF1 alpha, PGF2 alpha and PDG2. In addition, hydroxyfatty acid synthesis in excess of total prostaglandin production was observed. The substances mentioned are thought to be causally involved in the osteolytic activity of dental cysts.
