HOUSTON, TX, May 27, 2016 /24-7PressRelease/
-- NASA's Human Research Program
is releasing "Metabolomics: You Are What You Eat"
video to highlight its Twins Study
which uses omics to study Mark and Scott Kelly's metabolites. Omics
is an evolving field integrating collections of measurements, biomolecules and sub-disciplines to provide a more complete picture of health. It includes the studies of DNA
, your environment
, microbiome and metabolites
, to name a few. This is the sixth video in the omics miniseries
of eight videos. The video provides a broad overview of ongoing Twins Study research
on the International Space Station
and the importance of the metabolome, the collection of an individual's metabolites.
Metabolites are key small molecules. They're the chemicals in the body to let you do all the things you do. It's all these things that give you energy, like glucose. They let you move, think, and digest your food.
Using a mass spectrometer, researchers can analyze blood and urine for secreted metabolites. By following Scott and Mark Kelly both in space and on Earth, scientists can see a collection of changes occurring. Some chemicals are indicative of high stress but other chemicals are unknown. It is hoped that the Twins Study will show which stress molecules get activated at which times and what other kinds of metabolites are present and active. Identical twins share the same fertilized egg, thus, share similar genes. Because of similarities, researchers can focus on the metabolic changes.
One interesting aspect of this study is that the researchers know what Scott Kelly ate during the Twins Study
and One-Year Mission
. Diet definitely impacts a person's metabolites. They can see which foods cause what kinds of metabolic changes and how that evolves over time. It will be very informative to see how what you eat determines what you are chemically.
This information could be helpful for researchers creating recommendations to protect the health of astronauts embarking on long-duration missions, such as a journey to Mars
, as well as benefit humans on Earth.
NASA's Human Research Program
enables space exploration by reducing the risks to human health and performance through a focused program of basic, applied, and operational research. This leads to the development and delivery of: human health, performance, and habitability standards; countermeasures and risk mitigation solutions; and advanced habitability and medical support technologies.
