Fferentiation having a maximum at 21 d (6 fold raise when compared with day 0) (Figure 6B). The expression of DPPIV protein in 21 d differentiated Caco-2 cells was highly inhibited with both acute (56) and chronic (71) exposure to Ucn3. Moreover, we looked at the precise enzymatic activities of DPPIV and AP. In line with the boost of DPPIV protein expression, we discovered a rise inside the certain enzymatic activities of each DPPIV and AP during the time course of Caco-2 cell differentiation (Figure 6C and D). Nevertheless, we observed that only chronic exposure to Ucn3 reduced each enzyme activities to their day 0 level, whereas acute remedy with Ucn3 had only slightly impact onWJGwww.wjgnet.comJuly 28, 2017Volume 23Issue 28Ducarouge B et al .
