Synergistic effects of microgravity and space radiation (Nimblegen)

A mRNA microarray and microRNA microarray in dauer larvae of Caenorhabditis elegans (C. elegans) that endured spaceflight environment and space radiations environment during 16.5-day Shenzhou-8 space mission were performed. In our study wild type dys-1 mutant and ced-1 mutant strains of C.elegans endured four conditions during shenzhou-8 spaceflight mission including spaceflight static condition(ss) spaceflight 1-g centrifugal condition(sc) ground control condition(gc) and no-transport control.

Limited to the quantity of worm samples we performed technical-repeat test but not sample-repeat test.Accordingly 12 mRNA microarrays were performed.
