Δ40p53 tumours presented increased Ki67 H-scores (Fig. 6B) and microvessel areas (Fig. 6C) compared to LeGO, supporting the tumour volume findings (Fig. 5A) and indicating that high levels of Δ40p53 induce tumour growth, which may be associated with tumour-related angiogenesis. The gene discussed is MKI67; the disease is neoplasm.
