An ancient tumor in dogs might teach new tricks about cancer in people

An ancient, sexually transmitted dog cancer has baffled researchers until now. Canine transmissible venereal tumor - CTVT - spreads when cancer cells move from one dog to another during sexual contact. By comparing the genomes of 186 healthy dogs to two dog tumor genomes, NHGRI researchers discovered genetic mutations that prevented the dogs' immune systems from detecting and fending off invading cancer cells. Findings were reported online in the July 31, 2015 edition of Genome Research.
