Aberrant activation of the protein phosphatase calcineurin is found in various cancer types. Inhibition of calcineurin leads to a rapid clearance of leukemic cells and significantly improves animal survival in two mouse models of acute T lymphoblastic leukemia.


Mitogenic signals regulate cell proliferation through phosphorylation and dephosphorylation of intracellular proteins. Deregulation of these cascades can lead to uncontrolled cell division and cancer.
