Figure 7

Temporal effects of PD 406976 on SVG and U‐373MG glioma cells PKC enzyme activity. Cells were exposed to either DMSO (vehicle, control) or PD 406976 (2 µm) for 24, 48 and 72 h. Protein kinase C enzyme activity was quantified by measuring the dye‐labelled phosphorylated substrate using a Pierce Colorimetric PKC Activity Assay Kit. Data shown are from three experiments. The standard deviations at each point are shown but the error is too small to be seen. (○) Control (DMSO‐treated) cells; (•) cells treated with PD 406976 (2 µm).
