Derived from SAM analysis of union of and ; fast migrating cell lines colored in green, slow migrating cell lines colored in red ()

K-means (k = 3) identified three populations in malignant astrocytoma samples stratified by age that were visualized by multidimensional scaling (MDS); young (< median age) () and old patients (> median age) (). Kaplan-Meier survival analysis for clusters derived from k-means stratified by age; young (), old () show significant differences in overall survival.<p><b>Copyright information:</b></p><p>Taken from "Glioma cells on the run – the migratory transcriptome of 10 human glioma cell lines"</p><p>http://www.biomedcentral.com/1471-2164/9/54</p><p>BMC Genomics 2008;9():54-54.</p><p>Published online 29 Jan 2008</p><p>PMCID:PMC2275271.</p><p></p

Technical validation of microarray data by quantitative RT-PCR (QRT-PCR)

Average Log2 expression of relative mRNA copy numbers derived from three replicate microarray experiments and QRT-PCR of migratory (rim) over stationary (core) glioma cells (error bars = SD). Concordance between directionality of differential regulation between migratory and stationary cells for microarray and QRT-PCR data is displayed in parentheses (CYR61 = cystein rich 61, CTGF = connective tissue growth factor, RRAS2 = related RAS viral oncogene homolog 2, RhoA = ras homolog gene family member A, PCAF = p300/CBP-associated factor, ITM2B = integral membrane protein 2B, ZNF436 = zinc finger protein 436, MADH1 = mothers against decapentaplegic homolog 1 (). Expression pattern of () and () in comprehensive glioma expression data set (NB = normal brain, LGA = low grade astrocytoma, AA = anaplastic astrocytoma, GBM = glioblastoma multiforme). Bar indicates genes significantly (P < 0.05) differentially expressed between tumors and normal brain. Canonical pathways significantly over-represented in (black bars) and (white bar) ().<p><b>Copyright information:</b></p><p>Taken from "Glioma cells on the run – the migratory transcriptome of 10 human glioma cell lines"</p><p>http://www.biomedcentral.com/1471-2164/9/54</p><p>BMC Genomics 2008;9():54-54.</p><p>Published online 29 Jan 2008</p><p>PMCID:PMC2275271.</p><p></p

Hierarchical clustering of expression patterns of 20 core and rim samples ()

Scatterplot of principal component (PC) 9 against PC10 reveals two clouds representing core (black symbols) and rim samples (white symbols), respectively (). Proband gene AK098354 shows strong correlation with PC9, containing genes down-regulated in rim population () while cystein rich 61 (Cyr61) exhibits strong correlation with up-regulation pattern of PC10 (). GABRIEL was used to detect genes with similar expression patterns to proband genes AK098354 and Cyr61 ().<p><b>Copyright information:</b></p><p>Taken from "Glioma cells on the run – the migratory transcriptome of 10 human glioma cell lines"</p><p>http://www.biomedcentral.com/1471-2164/9/54</p><p>BMC Genomics 2008;9():54-54.</p><p>Published online 29 Jan 2008</p><p>PMCID:PMC2275271.</p><p></p
