Figure 4. PN increases PP2A activity.

Figure 4

IEC-6 cells were treated with PN (50 M) or equivalent concentration of DPN for 1 h. Cells were pre-treated with 10 M SB202190 (SB), 10 M okadaic acid (OA) or 100nM I1PP2A (PP2A INH) 30m prior to PN or DPN exposure. PP2A activity in cell lysates were measured. (*) PN exposure significantly elevated PP2A activity compared to all other variables (p<0.001, n=5). Data are shown as pmoles phosphate produced per mg protein in the form of mean S.E.
