Chrysin inhibited stem cell factor (SCF)/c-Kit complex-induced cell proliferation in human myeloid leukemia cells
چکیده انگلیسی

Stem cell factor (SCF) has important roles in the proliferation and differentiation of hematopoietic stem cells. The complex of c-Kit and its ligand SCF induce hematopoiesis, melanogenesis, and gametogenesis. However, the mechanism by which SCF induces cell proliferation in the human megakaryoblastic leukemia cell line, MO7e, and the signaling molecules involved, especially in downstream signaling of c-Kit, remain unclear. Here, we show that pharmacological inhibition of the PI3K pathway inhibits SCF/c-Kit signaling and cell proliferation. In addition, we find that the Shc/PDK1/PKC/Akt/c-raf signaling cascade is essential for SCF/c-Kit signal pathway. Our results also suggest that ERK5 is activated and translocated to the nucleus, activating CREB and STAT3. Interestingly, chrysin shuts down the SCF/c-Kit complex-induced signaling cascade. Taken together, these studies give additional insight into the molecular mechanism of SCF/c-Kit-induced cell proliferation and its inverse agonist, chrysin. Finally, these findings enhance our understanding of MO7e cell proliferation.
