KDR and lung cancer: 2016). BLAST alignment of the human VEGFR2 amino acid sequence with the putative canine version [EMBL nucleotide sequence database #AAEX03009081] shows 93% homology, with the relevant glutamine residue conserved between human and canine. Amplification of the KDR gene (≥4 copies) is also reported in human non‐small cell lung cancer (Nilsson et al. 2016). Cancer cell lines displaying KDR copy number gain showed enhanced VEGFR2 protein levels and activation of alternative signalling pathways compared to NSCLC cells lacking copy number amplification.
