In addition, it has been found that CEBPα is expressed and regulates miR-29b only in triple-negative breast cancers belonging to specific molecular subtypes, and that its role is dependent on adequate levels of the multidomain protein Vav1, which promotes the association between CEBPα and the promoter region of miR-29a/b1 [37]. Here, CEBPA is linked to triple-negative breast carcinoma.
