Jak of all trades? Not of leukaemia therapy
About one in five or six cases of adult leukaemia in Western populations relates to so-called chronic myeloid leukaemia, or CML. Treatment of CML usually relies on inhibitors of the abnormal protein that causes the condition but some patients do not respond to treatment and efforts are underway to develop a supplementary approach, targeting the so-called JAK2 kinase. Recent results from the groups of Veronika Sexl at the University of Veterinary Medicine, Vienna (Vetmeduni Vienna) and Giulio Superti-Furga at the Research Center for Molecular Medicine of the Austrian Academy of Sciences (CeMM) have called this strategy into question. The work is published in the current issue of the prestigious journal Nature Chemical Biology and is of immediate relevance to leukaemia treatment.
