초록

본 연구는 암탐지에 우수한 능력을 보유하고 있는 공여견의 냄새 탐지 능력이 복제를 통하여 보존될 수 있을지를 알아보기 위하여 설계되었다. 직장암 탐지에 특화되어 훈련된 개를 복제하였고, 복제된 개는 환자와 건강한 지원자들로부터 채취된 호흡 샘플을 사용하여 유방암을 탐지하도록 훈련 되었다. 복제개의 암탐지 민감도는 93.3%, 특이도는 99.5%로 공여견의 암탐지 민감도 및 특이도 (91% 및 99%)와 유사하였다. 게다가 복제개는 유방암의 초기 단계까지 성공적으로 탐지할 수 있었다. 따라서 우수한 암탐지 능력은 복제를 통해서 보존될 수 있을 것이다.

This study was conducted to ascertain whether the scent detection ability of a donor dog having extraordinary talent in cancer detection can be conserved through cloning. A specially trained dog for colorectal cancer detection was cloned, and she was trained and tested to detect breast cancers using breath samples collected from patients and healthy volunteers. Scent detection sensitivity of the clone was 93.3% and specificity was 99.5%, similar with those of donor (91% and 99%). Furthermore, the clone successfully detected early stage of breast cancers. Therefore, superior canine scent detection ability for cancer screening could be preserved through cloning.
