Mutation and expression of the p53 gene in human malignant melanoma

Abstract excerpt

Derangement of the p53 tumor suppressor gene has been implicated in the aetiology of a wide range of human neoplasias. We have previously determined that overexpression and mutation of the p53 gene in cultured metastatic melanomas is low (11%). However, two recent immunohistochemical studies have reported that > 85% of malignant melanoma specimens overexpress mutated p53 protein. In an effort to resolve this...
