Zoledronate synergises with imatinib mesylate to inhibit Ph primary leukaemic cell growth.

Abstract:

:We examined the in vivo effects and safety of the third generation bisphosphonate, zoledronate (ZOL) alone and combined with imatinib mesylate against primary Philadelphia chromosome positive (Ph+) leukaemic cells. ZOL inhibited the prenylation of Rap1A in leukaemic cells in vitro and synergised with imatinib to enhance the survival of mice engrafted with cells from imatinib-responders, but not from non-responders because of mutated BCR-ABL. These findings suggest that the combination of ZOL and imatinib accelerate the eradication of Ph+ clone, resulting in better prognosis of Ph+ leukaemia patients who have not yet acquired mutations.
