Supplementary MaterialsSI Desk 1. likened global transcription of forebrain hiPSC NPCs from six control and four SZ individuals by RNAseq (Desk 1; “type”:”entrez-geo”,”attrs”:”text message”:”GSE63738″,”term_id”:”63738″GSE63738), cultured as referred to (13, 14). As reported previously, hiPSC forebrain NPCs differentiate to a PRI-724 price combined neuronal human population of GABAergic and glutamatergic neurons; there is no difference in the power of control or SZ hiPSC NPCs to create III-TUBULIN-positive neurons (14) and neither transcriptional nor immunohistochemical characterization exposed any diagnosis-dependent variations in the local patterning of forebrain NPCs (13). Multi-dimensional scaling (MDS) solved most SZ and control hiPSC NPC examples (Fig. 1A); 848 genes had been significantly differentially indicated (FDR 0.05) (SI PRI-724 price Table 1), as illustrated by a heat map (Fig. 1C) and a Rabbit Polyclonal to Cytochrome P450 2A6 volcano plot (Fig. 1D). The differentially expressed genes in SZ hiPSC NPCs were significantly 3.6-fold enriched when compared to WNT target genes (p 10e-20) predicted by standard Classification and Regression Tree (CART) methods (16). The differentially expressed genes (FDR 0.05) were submitted to DAVID (http://david.abcc.ncifcrf.gov), which identified several significantly enriched pathways (Fig. 1B; Tables 2C3), including the WNT signaling pathway: 17.3-fold enrichment (p 10e-13; FDR 10e-11). The perturbed WNT genes are marked by red stars in the WNT signaling pathway diagram (Fig. 1E; Table 2). 6/6 differentially expressed WNT genes identified by RNAseq were confirmed when tested by qPCR (Fig. 1F; Table 2). Open in a separate window Fig. 1 RNAseq comparisons of control and SZ hiPSC NPCsA. Multidimensional scaling (MDS) of RNAseq gene expression of hiPSC NPCs from each of six control and four SZ patients segregates samples along the two leading fold change dimensions. Gene expression analysis was performed on passage-matched hiPSC forebrain NPCs cultured on matrigel. Cells were lysed in RNA BEE (Tel-test, Inc). RNA was chloroform extracted and treated with RQ1 RNAse-free DNAse (Promega). RNAseq samples PRI-724 price were prepared using the Illumina HiSeq 2500 RNA kit for 100nt/single end reads, four samples were run per lane. Raw cDNA reads were aligned to the hg19 reference with the spliced gap aligner Spliced Transcripts Alignment to a Reference (STAR) software, with count-based quantitation carried out via the Subread package featureCounts (http://bioconductor.org/packages/release/bioc/html/Rsubread.html) at both the geneic and exonic levels for UCSC and ensemble annotation builds. B. Pathway enrichment analysis based on DAVID. X-axis represents fold enrichment; Y-axis denotes pathways. The FDR are labeled on the right of the bar plot. C. Heat map of control and SZ hiPSC NPCs of 848 exclusive genes (FDR 0.05). The count number data had been normalized and modeled as over-dispersed Poisson data utilizing a adverse binomial model in the Bioconductor bundle edgeR (15). Collapse adjustments, p-values and fake discovery prices (FDRs) are from the same bundle for integrative evaluation. D. Volcano plots of ?log10 p-value versus log2 PRI-724 price fold-change mRNA amounts for SZ and control hiPSC NPCs.
