Canine lymphomas: DNA changes in tumour genes

Monika Drážovská, Katarína Šiviková, Gabriel Bóna


Lymphoma is the most frequent hematopoietic neoplasm in dog, and it shares some clinical, cytological, histopathological and molecular similarities with humans. In our study, DNA changes in TP53, c-KIT and N-RAS were detected in lymphoma tissues of cross breed bitch and Bernese Mountain Dog bitch. One transversion A/G at nucleotide position 138 in exon 5 in TP53 gene and one transversion A/G at nucleotide position 35 in exon 8 of c-KIT gene were observed in donor 2. It seems that these genes did not play a key role in canine lymphoma formation and progression.
