Kim HY et al. found that ectopic repair of DNAJB9 inhibited migration, invasion, and lung colonization of triple-negative breast cancer cells, which stabilized the FBXO45 protein by inhibiting its ubiquitylation, and decreased the ZEB1 abundance, thereby inhibiting epithelial-mesenchymal transition (EMT) and metastasis [49]. This evidence concerns the gene DNAJB9 and triple-negative breast carcinoma.
