IL33 and congestive heart failure: As shown in Figure 8, compared with the blank and sham groups, ST2 and IL-33 protein expression increased in the CHF, NC of miR-487b mimic, NC of miR-487b inhibitor, NC of si IL-33, and miR-487b inhibitor + si IL-33 groups (P < 0.05 for all) but decreased in the miR-487b mimic group and the si IL-33 group (P < 0.05 for all).
