Biochem/physiol Actions

Ki20227 is an orally active, potent and selective M-CSF receptor c-Fms (CSF-1R) tyrosine kinase inhibitor (IC50 = 2 nM vs. 12 nM/KDR, 451 nM/c-Kit, 217 nM/PDGFβ; >1 μM/BTK, EGFR, FGFR2, FLT3, Fyn, Met, c-Src, PKA, PKCα) that inhibits M-CSF-dependent (50 ng/mL) c-Fms phosphorylation (by >90% at 10 nM; RAW264.7) and cell growth (IC50 = 14 nM; M-NFS-60). Ki20227 prevents osteolysis in a rat model of bone metastasis (50 mg/kg/day p.o.) by inhibiting A375 tumor-induced osteoclast formation and decreases the number of osteoclast-like cells on bone surfaces in ovariectomized rats (20 mg/kg/day p.o.) in vivo.

It is now clear that microglia and macrophages are present in brain tumors, but whether or how they affect initiation and development of tumors is not known. Exploiting the advantages of the zebrafish (Danio rerio) model, we showed that macrophages

Iron is an essential component of the erythrocyte protein hemoglobin and is crucial to oxygen transport in vertebrates. In the steady state, erythrocyte production is in equilibrium with erythrocyte removal. In various pathophysiological conditions, however, erythrocyte life span is compromised

Macrophage colony-stimulating factor (M-CSF) is important in the development of macrophages and osteoclasts. Previous studies have also shown that CD11b(+) myeloblasts and osteoclasts play key roles during inflammation and bone destruction in arthritic lesions. In this study, we investigated whether
