The differential expression of certain ncRNAs such as miR-335, miR-383, miR-27a/b, and miR-376c, in exosomes from patients with HER2-positive and triple-negative breast cancer (TNBC), compared to healthy individuals, highlights the importance of exosomal ncRNAs in cancer (13–15). Here, ERBB2 is linked to triple-negative breast carcinoma.
