Research Abstract

We can simulate the skeletal muscle atrophy by using hindlimb suspension model. It was known that the skeletal muscle was atrophy during space staying. In this experiment, we compare these two models, hindlimb suspension and space flown mice, to investigate the mechanism of the skeletal muscle atrophy. We extracted RNA form these samples. RNA was hybridized to the Whole Mice Genome (4 X 44K) Oligo Microarray (Agilent Technologies) according to the manufacturer's protocol. Slide scanning was performed using the Agilent DNA Microarray Scanner.
