We also observed that there are remarkable negative relevant relations between the miR-362-5p expression and Sema3A protein expression (p < 0.0001) using in situ hybridization, immunohistochemistry, tissue microarray techniques, and human breast cancer cell lines MDA-MB-468 (triple-negative) and SK-BR-3 (HER-2+). This evidence concerns the gene SEMA3A and breast carcinoma.
