In another research, the circHIAT1/miR-19a-3p/CADM2 axis affected the epithelial-to-mesenchymal transition (EMT) and resistance to palbociclib with circHIAT1 and CADM2 downregulation in breast cancer tissues and cell lines and miR-19a-3p upregulation. The gene discussed is CADM2; the disease is breast carcinoma.
