Hyperoxia downregulates angiotensin-converting enzyme-2 in human fetal lung fibroblasts 2015-02-09 .txt text/plain 5010 273 51 We report here the findings that ACE-2 protein and enzyme activity are severely decreased by hyperoxia in human fetal lung fibroblast cultures. Figure 6 shows that the treatment of hyperoxia followed by normoxic recovery significantly increased ADAM17/TACE immunoreactive protein by threefold in the IMR90 cells (P < 0.05). IMR90 cells were exposed to hyperoxic or normoxic gas as described in Figure 1 (with recovery), but in the presence or absence of the ADAM17/ TACE inhibitor TAPI-2. IMR90 cells were exposed to hyperoxic or normoxic gas as described in Figure 1 (with recovery), but in the presence or absence of the ADAM17/ TACE inhibitor TAPI-2. IMR90 cells were exposed to hyperoxic or normoxic gas as described in Figure 1 (with recovery), then were recovered for western blotting of ADAM17/TACE as described in Materials and Methods. ./cache/cord-298515-5n7hxhbg.txt ./txt/cord-298515-5n7hxhbg.txt
