Abstract:
TWIST1 is thought to be a novel oncogene. Understanding the molecular mechanisms regulating the TWIST1 gene expression profiles in tumor cells may give new insights regarding prognostic factors and novel therapeutic targets in veterinary oncology. In the present study we partially isolated the TWIST1 gene in Felis catus and performed comparative studies. Several primer combinations were used based on the alignments of homologous DNA sequences. After PCR amplification, three bands were obtained, purified and sequenced. Several bioinformatic tools were utilized to carry out the comparative studies. Higher similarity was found between the isolated TWIST1 gene in Felis catus and Homo sapiens (86%) than between Homo sapiens and Rattus norvegicus or Mus musculus (75%). Partial amino acid sequence showed no change in the four species analyzed. This confirmed that coding sequences presented high similarity (~96%) between man and cat. These results give the first insights regarding the TWIST1 gene in cat but further studies are required in order to establish, or not, its role in tumor formation and progression in veterinary oncology.

- To perform comparative analyses of the Felis catus TWIST1 gene with homologous sequences in other species.
- To explore the potential role of TWIST1 in veterinary oncology.
Main Methods:
- Partial isolation of the TWIST1 gene in Felis catus.
- PCR amplification using various primer combinations based on homologous DNA sequences.
- Purification and sequencing of amplified DNA fragments.
- Bioinformatic analysis for comparative studies.
Main Results:
- High sequence similarity (86%) was observed between the isolated Felis catus TWIST1 gene and Homo sapiens TWIST1.
- Sequence similarity between Homo sapiens and Rattus norvegicus or Mus musculus was lower (75%).
- Partial amino acid sequence analysis revealed no changes across the four species studied, indicating high coding sequence similarity (~96%) between cats and humans.
Conclusions:
