Immature Schwann cells were treated with either GFP or GFP-PGC-1α-expressing adenovirus for 48 hours (MOI: 200:1) or with 5 μM forskolin for 3 days, and RNA was isolated and reverse transcribed for quantitative PCR using Taqman primer/probe sets. Results are grouped by gene function, and data are expressed as fold of GFP or 0 μM forskolin control, with normalization to β-actin. (n=3/group,
p < 0.05,
p < 0.01, T-test).
