Scientists from the University of California at Davis studied the issue of longevity of golden retrievers in relation to the tendency of these pets to oncopathology.
The Golden Retriever was and remains one of the most popular dog breeds in the world. They are smart, loyal, accommodating and friendly. But representatives of this breed are prone to oncology, up to 65 percent of such dogs die with this diagnosis.
As the journal GeroScience reports, geneticists analyzed the DNA of more than 300 dogs and compared the data of those that lived up to 14 years with the results of pets that had died earlier.
It was revealed that life expectancy increased by an average of two years in individuals with variations in the HER4 gene. Two years is approximately 15-20 percent of the lifespan of these animals. Greater increase in survival in women.
HER4 is part of the gene family responsible for susceptibility to oncology, especially in humans. Scientists hope that such research will contribute to a better understanding of cancer susceptibility in humans. Source
