Virus That Infected the First Animals Hundreds of Millions of Years Ago Is Essential for Embryo Development
CNIO researchers have discovered the essential role of endogenous retroviruses in embryonic development, specifically in the transition from totipotency to pluripotency. This study, which challenges the previous notion of ‘junk DNA’, sheds light on the symbiotic relationship between viral genes and early embryonic development, with implications for regenerative medicine. Credit: SciTechDaily.comAt least 8% of the human genome is genetic material from viruses. It was considered ‘junk DNA’ until recently, but its role in…
