摘要
Differentiation of PC12 cells by nerve growth factor (NGF) or fibroblast growth factor-2 (FGF2) is dependent on signaling mediated by extracellular regulated kinase (ERK). We investigated the involvement of receptor for hyaluronan mediated motility (RHAMM) in this signaling pathway. A single RHAMM 3.2 kb transcript was detected in PC12 RNA. Reverse transcriptase-polymerase chain reaction generated a 2141 bp cDNA that had identical sequence to rat brain RHAMM and showed no evidence of alternate splicing. Several RHAMM species were identified by Western blotting. Immunohistochemistry showed RHAMM localization to the cytoskeleton, neurites and growth cones. Following stimulation of PC12 cells with NGF or FGF2 RHAMM was co-immunoprecipitated by phosphorylation-specific anti-ERK antibodies, indicating a role for RHAMM in ERK signaling in PC12 cells.
