In a recent study scientists report that the enzyme 5-lipoxygenase (5-LO) plays a significant role in the survival of leukemic AML stem cells.
5-LO is known for its role in inflammatory diseases like asthma. A team led by Dr. Marin Ruthardt from the Haematology Department of the Medical Clinic II and Dr. Jessica Roos, Prof. Diester Steinhilber and Prof. Thorsten Jürgen Maier from the Institute for Pharmaceutical Chemistry showed that the leukaemic stem cells in a subgroup of AML could be selectively and efficiently attacked by 5-LO inhibitors. This was demonstrable in cell culture models as well as in leukemia mouse models.
Advertisement"These results provide the basis for the potential implementation of 5-LO-inhibitors as stem cell therapeutic agents for a sustained AML cure, although this must be investigated further in preclinical and clinical studies in humans," explains Dr. Ruthardt. "In addition, there are plans for further molecular biological studies with the objective of understanding exactly how the 5-LO inhibitors act on the leukaemic cells." Prof. Maier continued.
