I distinctly remember the first day I saw the images proving our hypothesis about the connection between a herpesvirus and urogenital cancer in wild California sea lions. Our research team was the first to use a revolutionary technique to probe preserved cancerous tissue from marine mammals as we looked for signals of specific viral genes.
And we found them: Wherever there was tumor, there also was a strong signal of multiple cancer-promoting viral genes, called oncogenes. There were no viral genes in the adjacent cancer-free tissue. This meant that the virus clearly played a role in cancer development and was not merely a bystander in the animals’ reproductive tracts.
