The tumour-suppressor protein p53 is mutated in many head and neck squamous cell carcinomas (HNSCCs). In this immunohistochemical study, similar numbers of p53-overexpressing cells were uniformly distributed throughout normal oral epithelium, irrespective of different smoking habits or the presence

Abstract
Hyperplastic lesions of the oral mucosa such as leukoplakia and oral lichan planus can eventually develop into squamous cell carcinomas. In the clinical treatment of these lesions it would be very important tobe able to predict the biological behaviour of an individual lesion. In 64 hyperplastic lesions and 85 squamous cell carcinomas of the oral mucosa, the expression of the mutant tumor suppressor gene p^53^and the grade of dysplasia of the lesions.

Data are non-existent regarding coincidental alterations in the expression of p53 and its downstream target genes MDM2 and p21 Waf1/Cip1 in gastric carcinogenesis. An immunohistochemical study was therefore performed to examine the interrelationships of p53, MDM2, and p21 Waf1/Cip1 expression in a s
In situ tissue dynamics were studied in 12 cases of human gastric mucosa, including normal gastric body mucosa and gastric glands with intestinal metaplasia, obtained from gastrectomy specimens of adenocarcinoma.

Epithelial dysplasia is usually used to establish the prognosis of oral premalignant lesions. Its assessment, however, is subjective and does not always correctly predict the outcome of the lesions in terms of malignant transformation. Early molecular alteration(s) that dictate the development of ca
