SHIPi improves hematologic recovery after chemotherapy.

ABSTRACT: The use of recombinant growth factors has led to improved hematopoietic function after chemotherapy, but hematologic and immune complications still occur after chemotherapy which can be life-threatening. Here we show that pan-SHIPi compounds can induce endogenous G-CSF and TPO production in vivo and can also increase host survival after a lethal fungal challenge. In addition, we show that consistent with their ability to induce G-CSF, pan-SHIPi compounds can promote increased granulopoiesis in normal mice and speed recovery of neutrophil counts after chemotherapy. We also report the identification of a novel SHIP1-selective inhibitor, A32, that also increases steady state production of both G-CSF and TPO. These findings indicate small molecule inhibitors of SHIP1 can promote hematologic re
