title: Detection of autoantibodies against survivin in sera from cancer dogs.
abstract: Survivin overexpression has been reported in relation to tumor malignancy, suggesting that it is an unfavorable prognostic marker, and antibody responses to this protein have been confirmed in human cancer patients. In this study, we investigated antibody responses to survivin in canine cancer cases, and examined the prevalence of such responses by enzyme-linked immunosorbent assay (ELISA) using recombinant canine survivin protein as the antigen. The cut-off value for positivity in the anti-survivin ELISA was 0.35, as determined using the mean absorbance +2 S.D. of samples from healthy dogs. Sera from 16 of 59 (27.1%) cancer and 3 of 25 (12%) non-cancer disease dogs were positive on ELISA. The highest positivity rates (>50%) among the cancer cases were seen in dogs with mammary tumor, squamous cell carcinoma and melanoma.
