Fferentiation having a maximum at 21 d (6 fold increase in comparison to day 0) (Figure 6B). The expression of DPPIV AMPK Activator Formulation protein in 21 d differentiated Caco-2 cells was extremely inhibited with both acute (56) and chronic (71) exposure to Ucn3. Furthermore, we looked in the particular enzymatic activities of DPPIV and AP. In line using the increase of DPPIV protein expression, we identified an increase inside the precise enzymatic activities of both DPPIV and AP through the time course of Caco-2 cell differentiation (Figure 6C and D). Nevertheless, we observed that only chronic exposure to Ucn3 lowered both enzyme activities to their day 0 level, whereas acute therapy with Ucn3 had only a bit effect onWJGwww.wjgnet.comJuly 28, 2017Volume 23Issue 28Ducarouge B et al .
