Additional evidence demonstrated that pristimerin increases miR-542-5p levels and that this miRNA directly targets ubiquitin-specific-processing protease 17-like protein 2 (USP17L2, also referred to as DUB3) [81], which promotes migration, invasion, and metastasis of breast cancer by stabilizing SNAI1 [273] (Figure 3 and Table 4). This evidence concerns the gene SNAI1 and breast cancer.
