Target information
Stromal cell-derived factor (SDF-1), by activating its cognate receptor CXCR4, plays multiple roles in cell migration, proliferation and survival in the development of the central nervous system. Recently, we have shown that functional SDF1alpha/CXCR4 signaling mediates chemotaxis through extracellular signal-regulated kinase (ERK) activation in the developing spinal cord. Here, we report that SDF1alpha/CXCR4 signaling activates beta-catenin/TCF transcriptional activity in embryonic rat spinal cord neural progenitors. Stimulation of neural progenitors with SDF1alpha resulted in cytoplasmic beta-catenin accumulation in 30 min, and lasted for approximately 240 min, while Wnt3a, a positive control, stabilized cytoplasmic beta-catenin in 120 min. Dose-response studies indicated that the beta-catenin stabilization effect could be detected in cells exposed to fM concentrations of SDF1alpha. This SDF1alpha-induced beta-catenin stabilization effect was inhibited by pretreatment of the cells with either pertussis toxin (PTX), an inactivator of G protein-coupled receptors, or PD98059, a MEK1 inhibitor. Concomitant with beta-catenin accumulation in the cytoplasm, SDF1alpha enhanced nuclear translocation of beta-catenin and its binding to nuclear transcription factor T cell-specific transcription factor/lymphoid enhancer-binding factor (TCF/LEF). Furthermore, SDF1alpha increased expression of genes such as Ccnd1, 2, 3, and c-Myc known as targets of the Wnt/beta-catenin/TCF pathway.
