ErbB2 is a well-established oncogene that is involved in different pathways in cancer [28], and the DIANA tool mirPath v.3 analysis showed that ErbB2 is a common target of miR-34a and -214, whereas miR-193b and -222 share the target PTEN, a known potent tumor suppressor, frequently mutated in human cancer [31]. This evidence concerns the gene ERBB2 and cancer.
