Prion infection increases the amounts of activated cPLA
in ScGT1 cells. (A) The amounts of activated cPLA2 in cell extracts from 1 × 106 GT1 cells (open bars) or ScGT1 cells (black bars). Values shown are the mean ± SD from 10 samples. (B) The amounts of activated cPLA2 in ScGT1 cells treated with varying concentrations of GDNF for 7 days (●) were plotted against the amounts of PrPSc in the same cells.
