Fferentiation having a maximum at 21 d (6 fold increase compared to day 0) (Figure 6B). The expression of DPPIV protein in 21 d differentiated Caco-2 cells was hugely inhibited with both acute (56) and chronic (71) exposure to Ucn3. Also, we looked in the specific enzymatic activities of DPPIV and AP. In line using the raise of DPPIV protein expression, we located an increase in the specific enzymatic activities of each DPPIV and AP throughout the time course of Caco-2 cell differentiation (Figure 6C and D). Having said that, we observed that only chronic exposure to Ucn3 decreased both enzyme activities to their day 0 level, whereas acute treatment with Ucn3 had only a little bit effect onWJGwww.wjgnet.comJuly 28, 2017Volume 23Issue 28Ducarouge B et al .
