Figure 1. miR-223-3p is overexpressed in head and neck cancer.
(A) miR-223-3p staining of normal epithelium showed few positive dots (asterisks). (B) Consecutive sections of T2 head and neck tumor stained for miR-223-3p or pan cytokeratin (CK) showed a high positive signal in CK positive transformed epithelial cells. A representative picture of consecutive sections from 8 tumors stained with miR-223-3p probe and CK is shown (magnification 800×), inset 1600×. Arrows highlighted polymormonuclear cells closed to miR-223-3p positive cells.
