Fferentiation having a maximum at 21 d (six fold boost in comparison to day 0) (Figure 6B). The expression of DPPIV protein in 21 d differentiated Caco-2 cells was highly inhibited with each acute (56) and chronic (71) exposure to Ucn3. Furthermore, we looked at the specific enzymatic activities of DPPIV and AP. In line using the boost of DPPIV protein expression, we found an increase inside the distinct enzymatic activities of both DPPIV and AP throughout the time course of Caco-2 cell differentiation (Figure 6C and D). On the other hand, we observed that only chronic exposure to Ucn3 reduced each enzyme activities to their day 0 level, whereas acute DPP IV/CD26 Proteins Recombinant Proteins treatment with Ucn3 had only slightly impact onWJGwww.wjgnet.comJuly 28, 2017Volume 23Issue 28Ducarouge B et al .
