| Research Abstract |
The mutation status of KIT and effects of imatinib on the mutant KIT were investigated in vitro and in clinical cases of cats and dogs with mast cell tumors(MCTs). Mutations in c-kit exon 8 and 9 were identified in tumor cells from cats and dogs with MCTs. These mutations caused constitutive phosphorylation of KIT. Imatinib suppressed the phosphorylation of the mutant KIT. A beneficial response to imatinib was observed in cats and dogs that had a mutation in c-kit exon 8 or 9.MCTs with mutations in c-kit exon 8 and 9 are potentially sensitive to imatinib in dogs and cats.
