Abstract Abstract：Avian leukosis in egg-type chickens is infectious neoplastic disease caused by avian leukosis viruse subgroup J( ALV-J). Expression of mutant tumor suppressor gene p53 in egg-type chicken with avian leukosis subgroup J was detected to study cancericidally molecular mechanism of ALV-J. Using immunohistochemistry method of strep avidin-biotin complex (SABC), many organs of illed egg-type chickens, involved liver, kidney, ventriculus glandularis, tumor, heart, pancreas, bone marrow, spleen, oviduct, lung, duodenum, thymus and bursa of fabricius were studied. And large numbers of mutant p53 protein were expressed in liver, kidney, ventriculus glandularis, tumor, oviduct. Moderate expression were detected in heart, pancreas, bone marrow, spleen, lung, duodenum, thymus and bursa of fabricius. The result suggested that expression of tumor suppressor gene p53 was concerned with occurrence and development of avian leukosis subgroup J.
