Our results demonstrated that miR-1, miR10a-5p, miR-20a-5p, miR-145, miR-143, miR-326, miR-642b and Let7a-5p are correlated with relevant histopathological features including stroma abundance, tumour grade, peritumoral inflammatory infiltrates, mucin type and tumour location. The gene discussed is MUC5AC; the disease is neoplasm.
