NASA’s Super-Muscular Mice Return to Earth From Space

Mighty Mice

On Tuesday, a SpaceX Dragon capsule splashed down in the Pacific Ocean, bringing with it 3,800 lbs of cargo from the Intercontinental Area Station.

That cargo delivery provided 40 mice, 8 of which researchers genetically engineered to be extremely muscular — and now that they’re back again on Earth, the “mighty mice” may well yield insights that could assist human astronauts continue to be healthy in space.

Myostatin Island

The 40 mice arrived on the ISS on December eight as section of Rodent Investigation-19, an experiment intended to improve scientists’ comprehension of how microgravity influences muscle and bone decline.

Scientists engineered the 8 tremendous-buff rodents to lack the protein myostatin, which triggered them to have about two times the skeletal muscle mass of the common mouse. Furthermore, astronauts taken care of some of the non-genetically engineered mice aboard the ISS with an experimental drug that inhibits myostatin.

Muscle and Bone

Now that the “mighty mice” and their companions are back again on Earth, researchers can analyze the rodents, wanting for techniques to manipulate myostatin to deal with human muscle and bone decline.

“The knowledge we attain about microgravity’s consequences on muscle tissue and bones will assist us to improve the wellness of astronauts – both equally in space and on Earth,” researcher Se-Jin Lee said in a push launch, “and also better recognize the promise that myostatin inhibitors maintain for the aged, people who are bedridden, and for people dealing with muscle-squandering similar to diseases like AIDS, ALS, most cancers, and so numerous many others.”
