title: The survival promoting peptide Y-P30 promotes cellular migration.
abstract: Y-P30, the 30 amino acid N-terminal peptide of the dermcidin gene, has been found to promote neuronal survival and differentiation. Its early presence in development and import to the fetal brain led to the hypothesis that Y-P30 has an influence on proliferation, differentiation and migration. Neurospheres derived from neural stem cells isolated from E13 mouse cortex and striatal ganglionic eminences were treated with Y-P30, however, the proportion of progenitors, neurons and astrocytes generated in differentiation assays was not altered. A short Y-P30 treatment of undifferentiated striatal and cortical neurospheres failed to alter the proportion of BrdU-positive cells. A longer treatment reduced the percentage of BrdU-positive cells and GABA-immunoreactive neurons only in striatal spheres. The presence of Y-P30 enhanced migration of T24 human bladder carcinoma cells in a wound-healing assay in vitro. Further, Y-P30 enhanced migration of T24 cells, rat primary cortical astrocytes and PC12 cells in chemotactic Boyden chamber assays. Together, these findings suggest that a major function of Y-P30 is to promote migration of neural and non-neural cell types.
