Resumen: | Mutations in the p53 tumor suppressor gene are the most common genetic alterations in human cancers. These mutations usually lead to strongly enhanced protein stabilization and allow detection by immunohistochemistry. Two monoclonal (DO-7 and PAb-240) and two polyclonal (Ab-7 and CM-l) antibodies were evaluated by standard immunoperoxidase method in domestic animal tumors, chiefly squamous cell carcinomas (Scq, and osteosarcomas as positive controls. Immunoreactivity was detected in SCC of cattle, sheep, horse and cat as well as in feline actinic keratosis, with PAb-240 and CM-l antibodies. One polyclonal antibody (Ab-7) did not give positive result at all, whereas DO-7 monoclonal antibody did not react in dogs and cats. Immunodetection of p53 protein is thus possible in all domestic species tested, especially with CM-l and PAb-240 antibodies, and p53 alterations seem to occur early in carcinogenesis of feli ne SCC as in comparable human lesions. |
