Abstract

Classical Hodgkin lymphoma has unique clinical and pathological features and tumour tissue is characterized by a minority of malignant Hodgkin Reed–Sternberg cells surrounded by inflammatory cells. In the present study, we report that the Hodgkin lymphoma-derived cell line L1236 has high expression...

In the present study, we report that the Hodgkin lymphoma-derived cell line L1236 has high expression of 15-lipoxygenase-1 and that these cells readily convert arachidonic acid to eoxin C4, eoxin D4 and eoxin E4.
