Space environmental factor impacts upon murine colon microbiota and mucosal homeostasis
We report how high and low linear energy transfer (LET) radiation microgravity and elevated dietary iron affect colon microbiota (determined by 16S rDNA pyrosequencing) and colon function. Three independent experiments were conducted: 1) fractionated low LET gamma radiation (137Cs 3 Gy RAD) high Fe diet (IRON) (650 …
