Immunohistochemical staining for MDM2 and p53 in human oesophageal carcinoma. The data show expression levels of MDM2 (A×100, B×400) and p53 (C×100, D×400) compared with the negative control (E×100, F×400) in tumour tissues from patients with OSCC. Amplification of the MDM2 gene (G×1000) compared with the negative control (H×1000) according to FISH in tumour tissues from patients with OSCC.
