On Tuesday, a SpaceX Dragon capsule splashed down in the Pacific Ocean, bringing with it three,800 kilos of cargo from the International Place Station.
That cargo shipping incorporated 40 mice, 8 of which researchers genetically engineered to be particularly muscular — and now that they’re back on Earth, the “mighty mice” may yield insights that could assistance human astronauts remain healthy in space.
The 40 mice arrived on the ISS on December eight as element of Rodent Study-19, an experiment designed to make improvements to scientists’ being familiar with of how microgravity has an effect on muscle and bone loss.
Scientists engineered the 8 super-buff rodents to absence the protein myostatin, which triggered them to have about twice the skeletal muscle mass mass of the normal mouse. Furthermore, astronauts addressed some of the non-genetically engineered mice aboard the ISS with an experimental drug that inhibits myostatin.
Muscle mass and Bone
Now that the “mighty mice” and their companions are back again on Earth, scientists can examine the rodents, wanting for ways to manipulate myostatin to deal with human muscle mass and bone decline.
“The knowledge we acquire about microgravity’s effects on muscle tissues and bones will support us to greatly enhance the health of astronauts – both of those in space and on Earth,” researcher Se-Jin Lee stated in a push launch, “and also superior have an understanding of the promise that myostatin inhibitors maintain for the aged, persons who are bedridden, and for people today dealing with muscle-wasting connected to illnesses like AIDS, ALS, most cancers, and so several some others.”
