Outline of Final Research Achievements |
The present study revealed the pathological features of breed specific diseases occurring in Pembroke Welsh Corgi(PWC) dogs, especially histiocytic sarcoma and degenerative myelopathy. Regarding histiocytic sarcomas, cell line derived from leptomeningealhistiocytic sarcomas in a PWC dog was established. Two additional cell lines from synovial histiocytic sarcoma of a flat-coated retriever dog and canine cutaneous Langerhans cell histiocytosis have been successfully established. These three types of cell lines will be exellent tools for the basic researches on tumoregenesis and therapeutic drug development on histiocytic sarcomas, not only in dogs but also in humans. Regarding canine degenerative myelopathy, autophagy abnormality is involved in addition to SOD1 mutation in PWC dogs.
