Dogs are loyal friends of mankind, but dog lovers must face the cruel fact that most dogs only live for ten years. However, some American researchers are studying an antibiotic called "rapamycin" (rapamycin) and hope to use this drug to extend the life of pet dogs. Currently, the drug has shown early results in mouse experiments.

　　reported that Matthew Kevalein, associate professor of pathology at the University of Washington in the United States, said that rapamycin can not only extend life, but also improve age-related physiological decline. Studies have shown that the cardiovascular function of experimental animals is improved, cancer lesions are delayed, immune function is partially improved, and cognitive function is also improved. Experiments show that, compared with mice without rapamycin, two experimental mice of the same age have younger physiological functions, and their life span is extended by 20% to 30%. The research team will also conduct experiments on dogs. According to reports, rapamycin has been used to treat organ transplant patients in the past to prevent postoperative rejection. Currently, researchers have discovered that they may have anti-aging functions. The main principle of this antibiotic is to target proteins that control the speed of cell replication and enhance the cell's ability to break down waste products, thereby slowing down the rate of aging. If rapamycin is proven to affect dogs, it may be applied to humans in the future and become a new generation of preventive drugs. By then, both humans and pet dogs can stay together longer and healthier.
