Role of arachidonic acid metabolism in thymocyte apoptosis after irradiation

The present study demonstrates that DNA fragmentation, nuclear pycnosis and trypan blue staining of irradiated thymocytes is prevented by inhibition of the lipoxygenase pathway of arachidonic acid metabolism and is not affected by cyclooxygenase inhibition. Exposed to irradiation [ 3H]arachidonic ac...
