Immunomorphological characteristics markers of apoptosis of pulmonary adenocarcinoma at workers of plutonium manufacture
This work is aimed to identify changes in levels of apoptosis and cell proliferation markers in pulmonary tumour tissues in workers following occupational radiation exposure. We analyzed immune and morphological specific characteristics of apoptosis system using autopsy samples of 40 pulmonary adenocarcinomas including 22 samples from Mayak PA radiation workers. Levels of apoptosis regulating proteins were shown to differ considerably in pulmonary adenocarcinoma foci of plutonium workers internally exposed to alpha-particles compared to those in occupationally unexposed individuals.
