Fig. 5. The effect of overexpression of PKCßI and PKCßII on proliferation of neuroblastoma cells. SK-N-BE(2) cells were transfected with expression vector CMS-EGFP containing either no insert (-) or cDNA coding for full-length PKCßI (ßI) or PKCßII (ßII). The percentage of transfected cells positive for BrdUrd was counted. At least 200 transfected cells/experiment identified by the presence of EGFP were counted, and the data are mean ± SE.
