Representative immunohistochemical findings of the effect of IκBαM overexpression in differently sized xenograft tumours derived from SNU-668Vector cells (left lanes) or SNU-668IκBαM cells (right lanes). Tumour sections were stained with H&E (A and B), anti-NF-κB p65 (C and D), anti-PCNA (E and F), anti-cleaved caspase-3 (G and H), anti-CD31 (I and J), or anti-HIF-1α (K and L). All sections were lightly counterstained with haematoxylin. Scale bars=50 μm.
