Apoptosis control and proliferation marker in human normal and neoplastic adrenocortical tissues.
Bottom Line: MIB-1 was expressed in all carcinomas with values (13.7+/-3.1%) significantly (P<0.0006) higher than in the other groups.In conclusion, the present data indicate that the apoptosis control and proliferation activity evaluated by the p53 and MIB-1 proteins are impaired in adrenal carcinomas but preserved in adenomas, independently of their functional status.Therefore, these immunohistochemical markers, overexpressed in carcinomas only, may be useful in the diagnosis of malignancy in adrenocortical tumours.

Mentions: No p53 protein was detected in any sample of N, APA and NFA. In contrast, p53 was expressed in 15 out of 16 (94%) CA and in 10 specimens the staining involved between 10–50% of the malignant cells (Figures 1Figure 1
