Microarray analysis of transgenic mice specifically overexpressing FOXO1 in skeletal muscle (FOXO1 Tg mice)

ABSTRACT: FOXO1, a member of the FOXO forkhead type transcription factors, is markedly up-regulated in skeletal muscle during atrophy. Previously, we created transgenic mice specifically overexpressing FOXO1 in skeletal muscle (FOXO1 Tg mice). These mice weighed less than the wildtype control mice, had a reduced skeletal muscle mass. In this study, to better understand changes in skeletal muscle during atrophy, we performed a microarray analysis of skeletal muscle in wild-type control and FOXO1 Tg mice. The microarray data shows that in the skeletal muscles of FOXO1 Tg mice, gene expression of PGC-1β, a transcriptional regulator whose increased expression activates energy-expenditure-related genes in skeletal muscles, is decreased.
