Illumina HiSeq 2500
Description
Purpose: To gain further mechanistic insight into phenotypic differences between wild type pancreatic islets and islets with loss of function of 4 Box C/D snoRNAs from the Rpl13a locus (U32a, U33, U34 and U35a). Methods:High quality total RNA (RIN = 8.5) was prepared from hand-picked islets (n = 4 mice/genotype) using TRIZOL reagent, treated with Turbo DNAse (Thermo Fisher), and used to prepare SeqPlex RNAseq libraries (Sigma). Sequencing was performed by the Washington University Genome Technology Access Center using two lanes of Illumina HiSeq 2500, 1x50. Reads were demultiplexed and trimmed, and STAR alignment and quantification analysis was carried out using the Partek Flow platform. Uniquely aligned reads were quantified to identify genes with at least a two-fold change between genotypes with p < 0.05 and FDR step-up of 0.05. Results:We observed 2-fold or greater differences in the expression of only six genes. Conclusions: Our data indicate that loss-of-function of snoRNAs from the Rpl13a locus is associated with modest changes in mRNA abundance. Overall design: Examination of murine pancreatic islet mRNA differential expression between wild type mice and mice with loss-of-function of U32a, U33, U34, and U35a snoRNAs.

Illumina humanRef-8 v2.0 expression beadchip
Description
Human and rat umbilical cord matrix mesenchymal stem cells (UCMSC) possess the ability to control the growth of breast carcinoma cells. Comparative analyses of two types of UCMSC suggest that rat UCMSC-dependent growth regulation is significantly stronger than that of human UCMSC. Their different tumoricidal abilities were clarified by analyzing gene expression profiles in the two types of UCMSC. Microarray analysis revealed differential gene expression between untreated nave UCMSC and those co-cultured with species-matched breast carcinoma cells. The analyses screened 17 differentially expressed genes that are commonly detected in both human and rat UCMSC. The comparison between the two sets of gene expression profiles identified two tumor suppressor genes, adipose-differentiation related protein (ADRP) and follistatin (FST), that were specifically up-regulated in rat UCMSC, but down-regulated in human UCMSC when they were co-cultured with the corresponding species' breast carcinoma cells. Over-expression of FST, but not ADRP, in human UCMSC enhanced their ability to suppress the growth of MDA-231 cells. The growth of MDA-231 cells was also significantly lower when they were cultured in medium conditioned with FST, but not ADRP over-expressing human UCMSC. In the breast carcinoma lung metastasis model generated with MDA-231 cells, systemic treatment with FST-overexpressing human UCMSC significantly attenuated the tumor burden. These results suggest that FST may play an important role in exhibiting stronger tumoricidal ability in rat UCMSC than human UCMSC and also implies that human UCMSC can be transformed into stronger tumoricidal cells by enhancing tumor suppressor gene expression.

- Illumina HumanHT-12 V4.0 expression beadchip
Description
Recurrent venous thromboembolism (VTE) occurs infrequently following a provoked event but occurs in up to 30% of individuals following an initial unprovoked event. We studied 134 patients with VTE separated into 3 groups: (1) low-risk patients had 1 provoked VTE; (2) moderate-risk patients had no more than 1 unprovoked VTE; (3) high-risk patients had 2 unprovoked VTE. 44 individuals with no history of VTE were enrolled as healthy controls. Consented individuals were enrolled at 4 medical centers in the US. Total RNA from whole blood was isolated and hybridized to Illumina HT-12 V4 Beadchips to assay whole genome expression. Using class prediction analysis, we distinguished high-risk patients from healthy controls with good receiver operating curve characteristics (AUC=0.88). We also distinguished high-risk from low-risk individuals, moderate-risk individuals from healthy controls, and low-risk individuals from healthy controls with AUCs of 0.72, 0.77 and 0.72, respectively. Using differential expression analysis, we identified genes relevant to coagulation, immune response and vascular biology, such as SELP and CD46, which were differentially expressed in at least two comparisons. Neither approach distinguished the moderate-risk patients from the high-risk or low-risk groups. Gene expression profiles may provide insights into biological mechanisms associated with patients at risk for recurrent VTE. Prospective studies are needed to validate these findings.
