Living in space is not the same as living on earth as it not only changes the outlook of a person but transforms gene expression too. For nearly a year, commander Scott Kelly living onboard the international space station. His twin brother, a retired astronaut, Mark Kelly back on earth.
NASA’s preliminary results expose that astronaut Scott Kelly’s genetic expression did not return to baseline after his arrival to Earth. NASA wants to examine what happened to Scott Kelly before and after he spent one year aboard the International Space Station and they were going to compare Scott to his twin brother, Mark when he got back.
Nasa suggesting that year in space activated so-called space genes. They witnessed a 7% change in gene expression. Scott was two inches taller when he landed. He was also lighter than Mark, losing muscle. But the genes in the study, not a perfect match anymore.
Scott Kelly said, “I no longer have to call Mark my identical twin brother anymore”.
Scott Kelly’s change proposes longer-term alterations identified with no less than five natural pathways and capacities and this one of a kind report were discharged at the 2018 Investigator’s Workshop for NASA’s Human Research Program in January. Preceding this, the space office distributed its initial round of preparatory outcomes at the 2017 Investigator’s Workshop.
Scientists measured Kelly’s metabolites, proteins, and cytokines to track physical changes caused by time in space. Scientists stated that spaceflight is associated with oxygen-deprivation stress, increased inflammation and dramatic nutrient shifts that affect gene expression and the team focused on chemical changes in RNA and DNA to better understand the genetic dynamics of each twin.
