No association was found between the expression levels of miR-125-5p, miR-143-3p and miR-145-5p and the hormonal receptor status of the lesions (Estrogen Receptor positive or negative: ER+/−, Progesteron receptor positive or negative: PR +/− and Human epidermal growth factor receptor positive or negative: HER2 +/−; Supplementary Table S2) or with tumour subtypes (all p-values > 0.05). This evidence concerns the gene ERBB2 and neoplasm.
