Affymetrix Rat Genome U34 Array (rgu34a)
Description
Endocardial (EE) and Aortic (AE) endothelial cells were isolated from the same two rats, pooled (EE and AE kept separately) and cultured for 2 passages. Culture conditions and confluence of EE and AE cell cultures were kept as identical as possible. RNA was isolated and the expression profile of both endothelial cell types was compared using the Affymetrix rat genome U34A array.

Description
Using a CML mouse model, we identified differences in gene expression between leukemic compared with non-leukemic LTHSC, including increased expression of the thrombopoietin (THPO) receptor MPL. LTHSC expressing high levels of MPL showed enhanced JAK/STAT signaling and proliferation in response to THPO in vitro, and increased leukemogenic capacity in vivo compared to LTHSC with low MPL expression. Although both G0 and S-phase subpopulations were increased in MPL expressing LTHSC, LSC capacity was restricted to quiescent cells. Inhibition of MPL expression in CML LTHSC resulted in reduced THPO-induced JAK/STAT signaling and leukemogenic potential. Similar observations were made with LTHSC from CML patients. MPL expressing LTHSC demonstrated reduced sensitivity to BCR-ABL TKI treatment but demonstrated increased sensitivity to JAK inhibitors. Our studies identify MPL expression levels as a key determinant of heterogeneous leukemia-initiating capacity and drug sensitivity of CML LTHSC, and suggest that MPL-expressing CML stem cells are critical targets for therapy. Overall design: To evaluate heterogeneity in LSC potential, donor LTHSC from SCL-tTA/BCR-ABL mice (200 cells/mouse) were transplanted into a cohort of congenic FVBN mice. Recipient mice were followed for engraftment of donor CML cells and development of CML. LTHSCs were isolated from leukemic and non-leukemic recipient mice and global gene expression was analyzed using RNA-Seq.

Description
The adaptor protein Lnk is an important negative regulator of HSC homeostasis and self-renewal. This study aims to investigate the role of Lnk in HSC aging. Here we performed expression profiling of bone marrow CD150+CD48-LSK LT-HSCs from young and old WT and Lnk-/- mice. Results identify select Lnk-mediated pathways with potential involvement in HSC self-renewal and aging.

Description
The human ribosomal protein S3 (RPS3), a component of the small 40S ribosomal subunit, is mainly involved in ribosomal maturation and initiation of translation through association with initiation factors. In this study, we firstly identified that RPS3 played an important role in HCC progression. We performed RNA sequencing to profile gene expression patterns before and after RPS3 knockdown. Overall design: SMMC-7721 cells were transfected with RPS3 siRNA or negative control, and overall transcriptomic changes were then examined by RNA sequencing, in duplicate, using Illumina Hiseq 2500 platform.
Publication Title

Description
Purpose: The goal of this sequencing is to investigate alterations in gene expression that result from impaired retinoid signaling compared with control, and how the RA signaling controls spermatogonia differentiation Methods: THY1+ spermatogonia mRNA profiles of 4-day-old control and germ cell specific impaired retinoid signaling mice were generated by High-throughput sequencing Results: Gene ontology (GO) analysis of the genes at the top of the ranked genes indicated enrichment in genes associated with roles in reproduction, transcription and spermatogenesis. In total, we identified 1633 and 742 transcripts (Reads Per Kilobase of transcript per Million mapped reads (RPKM) > 1) that were significantly (p-value < 0.05, > 1.5-fold difference) down- and up-regulated, respectively, in the germ cell mutants compared with the controls. Most importantly, we found that the majority of transcripts of replication-dependent core histone genes, histone cluster 1 (Hist1) were downregulated in germ cell mutants. Overall design: THY1+ spermatogonia mRNA profiles of 4-day old germ cell specific impaired retinoid signaling and control mice were generated by deep sequencing, twice, using Illumina HiSeq 2000

Description
Human neonates and older adults frequently exhibit a reduced capacity to control microbial infections. A variety of mechanisms involving both the innate and adaptive immune systems have been proposed to contribute to these deficiencies. The emergence of RNA sequencing (RNA-seq) as an accurate and quantitative method for examining mRNA levels provides an opportunity to compare transcriptional responses to a stimulus at a global scale in neonates, adults, and older adults. An examination of ex vivo monocyte responses to lipopolysaccharide stimulation or Listeria monocytogenes infection (with cord blood monocytes representing neonatal monocytes) revealed extensive similarities between all three age groups, with only a small number of genes exhibiting statistically significant differences. Using transcription factor motif analyses and RNA-seq data sets from a variety of mouse mutants, the most significant neonatal deficiencies corresponded to genes that require interferon response factor-3 or type 1 interferon signaling for their activation. In older adults, the most striking difference was broad, low-level activation of inflammatory genes prior to stimulation, consistent with prior evidence of a chronic inflammatory state in older adults. These results demonstrate the value of quantitative RNA-seq analyses and the feasibility of cross-species comparisons between well-defined mouse networks and human data sets. Overall design: RNA-seq of primary cells from three independent donors in three different age-groups across 3 time-points stimulated with either LPS or Listeria monocytogenes.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
Human conjunctival cell lines are useful tools for modeling ocular surface disease and evaluation of ocular drugs. Here we demonstrate that the IOBA-NHC and the ChWK conjunctival epithelial cell lines show, using an unbiased gene microarray approach, unique gene expression signatures that differ from primary conjunctival epithelial cells (PCEC) and conjunctival tissue. Globally, the expression profile obtained with the Affymetrix U133A chip (>22000 genes) from PCEC was clustered more closely to conjunctival tissue than either of the 2 cell lines. However, when restricted to Gene Ontology sub-categories: cellular defense, viral replication/cycling, antigen presentation, anti-oxidant pathways and ubiquitin ligase complex, the cell lines correlated reasonably well to PCEC (r > 0.70). In the category response to inflammation, correlation of cell lines to PCEC was poor (r = -0.012 and 0.041 for IOBA-NHC and ChWK respectively). In general, the expression profile in IOBA-NHC cells was better correlated to PCEC than the ChWK cells. This was statistically significant (p<0.05) when one considers all the genes on the chip, or for proteins in the extracellular region, response to wounding, stress, lipid, protein and organic acid metabolism, development and differentiation. Our results are useful for the choice of conjunctival cell lines, if necessary, in future experiments, to increase validity of extrapolation to clinical scenarios.

- Affymetrix Human Genome U95 Version 2 Array (hgu95av2)
Description
Human prolactinomas (n=4, 3 males and 1 female) were obtained during trans-sphenoidal surgery as part of an ongoing accession of human pituitary tumors. The study was approved Institutional Review Board (IRB) of Emory University, and informed consent obtained for all subjects. Tumors were microdissected and removed using the surgical microscope, rinsed in sterile saline, snap-frozen in liquid nitrogen, and stored (-80 ) until analysis. Each tumor fragment was confirmed independently by a neuropathologist by histology and immunohistochemistry prior to molecular analysis. Three normal pituitary glands from cadavers were obtained from the National Resource Center (NDRI, www.ndriresource.org). Each human tissue sample was analyzed using Affymetrix Human Genome U95Av2 arrays.
