Abstract:
Thirty-one naevus cell naevi, 30 dysplastic naevi and 12 fibromatous naevi were stained for the presence of p53 and Growth Arrest DNA Damage genes. All naevus cell naevi and fibromatous naevi were highly positive for GADD genes and negative for p53. Dysplastic naevi had significantly lower GADD34 and GADD153 expression as well as higher p53 expression in relation to the other naevi groups. The absence or decrease of GADD genes expression in naevus may indicate a potential malignant transformation.
