The predecessor to this investigation, ICE-First, was flown to ISS in 2004.
Examine RNA interference under space environment and evaluate effect of space environment for protein phosphorylation and signal transduction concerning muscle fibers formation using gene knock downed C.elegans
Information PendingEarth Applications
The experimental data will provide the important information to clarify the muscle atrophy in space and also on the Earth. The results will be the first evidence that RNA interference will be a powerful technique in space experiment to investigate the effect of microgravity on gene expression.
