Figure 6B showed that IL33 mainly localized in the epithelial cells of the mouse uterus and decreased in the adenomyosis mouse model. We further found that IL33 protein expression, consistent with the HOXA10 level, was dramatically downregulated compared with that in the control group (Figures 6C–E). In addition, IL33 and HOXA10 protein expression was positively related (Figure 6F). Here, IL33 is linked to adenomyosis.
