Proanthocyanidins Activate Nrf2/ARE Signaling Pathway in Intestinal Epithelial Cells by Inhibiting the Ubiquitinated Degradation of Nrf2

<div>PC-induced relative protein levels of Keap1 in MODE-K cells. (a) Cells were treated with 0, 1, 2.5, and 5 <i>μ</i>g/mL PC for 24 h. All tests were repeated at least three times. (b) Cells were treated with 5 <i>μ</i>g/mL PC for 0, 3, 6, 12, and 24 h. All tests were repeated at least three times. “<svg height="6.01072pt" id="M28" style="vertical-align:-0.04980993pt" version="1.1" viewbox="-0.0498162 -5.96091 7.75925 6.01072" width="7.75925pt"
