Statements

Type Excerpt DOI
Mutation Description "In addition, MMP7—which promotes metastasis when expressed at high levels (Li et al. 2014; Koskensalo et al .2011)—contains a premature stop codon in sperm whales, a putative sperm whale-specific mechanism to reduce cancer incidence." 10.1093/gbe/evx187
Methodology & Validation "To further ensure that assembly artifacts are not mistaken for gene losses, we used the Trace Archive Nucleotide BLAST to search inside RNA-Seq sets SRX220358, SRX220357, SRX220356, SRX220355, SRX220354, SRX220353, SRX220352, SRX220351 and SRX220350." 10.1093/gbe/evx187
Phenotypic "A loss of several proteases in cetaceans suggests a trend towards a milder inflammatory response relevant to Peto’s paradox: A theory postulated to explain the lower relative incidence of cancer in large mammals (CaulinandMaley2011)." 10.1093/gbe/evx187
