Expression data from the cerebral cortex of sugarcane top ethanolic extract (STEE)-administered SAMP8 mice, water-administered SAMP8 mice, and water-administered SAMR1 mice.

STEE regulated a wide range of biological processes in the cerebral cortex of SAMP8 mice. RNA samples were extracted from cerebral cortices with Isogen (Nippon Gene, Toyama, Japan) and were amplified and biotinylated with Affymetrix 3’ IVT PLUS Reagent Kit (Affymetrix, Santa Clara, CA), according to the manufacturer’s instructions. The integrity of RNA was quantified using NanoDrop 2000 spectrophotometer (Thermo Scientific, Wilmington, DE) and one hundred ng of total RNA from each sample was used to generate amplified and biotinylated complementary RNA (cRNA) from poly (A) RNA in a total RNA. Biotinylated cRNA was hybridized onto Affymetrix Mouse Genome 430 PM array strips (Affymetrix) for 16 hrs at 45℃ in the hybridization station. The hybridized arrays were washed, stained, and scanned with GeneAtlas Fluidics and Imaging Station. Microarray analysis was performed in duplicates for each samples. Water-administrated SAMP8 mice are controls to STEE-administrated SAMP8 mice. Water-treated SAMR1 mice are normal aging mice.
