In the immunohistochemical analysis (n = 10), tissues that expressed high levels of miR-30a (tumor-to-normal (T/N) ratio ≥ 0.50-fold as defined in [10]), had intense positive staining for the three claudin proteins, and had reduced or undetectable levels of Slug and fascin were from well-differentiated, lymph node metastasis (LNM)-negative, and non-invasive tumors. The gene discussed is FSCN1; the disease is neoplasm.
