Abstract
Microgravity and radiation exposure experienced during space flights result in immune system suppression. Subsequent research was conducted on the ISS in real microgravity and radiation environments experienced during a Spacex-3 mission (UR-l) launched April 18, 2014. The experiment was designed and integrated into Nanoracks hardware for testing on the ISS. Experimental design and cellular protocols were developed for a time period over a year. During such time dry runs, microgravity grounds models and cell conditions were optimized. Normal lymphocytes were flown on a Nanoracks platform with and without benzofuran-2-carboxylic acid derivative KMEG for 6 days. Appropriate fixatives for RNA isolation and protein analysis were added at the end of 6 days post activation on the ISS. Initial gene array analysis of samples revealed 1 2 that 78 genes were differentially expressed in microgravity exposed lymphocytes compared to ground control lymphocytes. Significantly up-regulated T cell proliferation genes in Spacex- 3 KMEG treated lymphocytes compared to control via Illumina analysis (P
