Table 28.S2: The astrocyte transcriptome (download)

Analysis from Lovatt et al. (2007) was produced by comparing adult cortical GFAP-GFP+/GLT1+ astrocytes to GFAP-GFP–/GLT1– cells (n=3). Analysis from Cahoy et al. (2008) was produced by comparing postnatal (P)16-17 fluorescence activated cell sorting- (FACS) and panning-isolated astrocytes (n=5) to P16-17 panning-isolated neurons (n=3). Analysis from Doyle et al. (2008) was produced by comparing TRAP affinity-purified mRNA from BAC-transgenic Aldh1l1 mice. From Doyle et al. (2008), each sample (n=4) derived from several 8-10 week old mice, and was compared to unbound affinity-purified samples (n=2). Each of the three datasets was normalized individually using the RMA algorithm in R/Bioconductor. The same software was used to calculate statistical values using the limma package. Fold changes are log base 2. P-values are FDR-corrected. A representative probe was chosen for cases where a gene has more than one probeset for the platform. This was done by choosing the probeset with the lowest p-value for that gene. When there was a p-value tie, the probeset with the higher value fold change was chosen.
