Description
In this study we demonstrate that the lung mononuclear phagocyte system comprises three interstitial macrophages (IMs), as well as alveolar macrophages (AMs), dendritic cells and few extravascular monocytes. Through cell sorting and RNAseq analysis we were able to identify transcriptional similarities and differences between the three pulmonary IM subtypes, with reference to the more well-characterized alveolar macrophage Overall design: Pulmonary Interstitial and Alveolar macrophages were FACS sorted from the lungs of steady state 8-10 week old B6 mice, in triplicate. Extracted RNA was examined by RNAsequencing. The tar archive GSE94135_jakubzick_2019*tar available at the foot of this page contains the supplementary processed data used for comparisons with data in GSE132911. Data were processed as described in GSE132911.

Description
Macrophages (MF) have been shown to contribute to fibrogenesis, however the underlying mechanisms and specific MF subsets involved remain unclear. Lung MF can be divided into two subsets: Siglec-Fhi resident alveolar MF and CD11bhi MF that primarily arise from immigrating monocytes. RNA-seq analysis was performed to compare these MF subsets during fibrosis. CD11bhi MF, not Siglec-Fhi MF, expressed high levels of pro-fibrotic chemokines and growth factors. Overall design: C56BL/6 WT mice were treated intratracheally with bleomycin. 8 days later, CD64+Mertk+ MF were sorted into Siglec-F(high) and CD11b(high) subsets. SiglecF(high) MF from naïve mice were also sorted. RNA was isolated and RNA-seq was performed to compare MF subsets.

Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
The eukaryotic cell cycle, driven by both transcriptional and post-translational mechanisms, is the central molecular oscillator underlying tissue growth throughout animals. While genome-wide studies have investigated cell cycle-associated transcription in unicellular systems, global patterns of periodic transcription in multicellular tissues remain largely unexplored. Here we define the cell cycle-associated transcriptome of the developing Drosophila wing epithelium and compare it with that of cultured Drosophila S2 cells, revealing a core set of periodic genes as well as a surprising degree of context-specificity in periodic transcription. We further employ RNAi-mediated phenotypic profiling to define functional requirements for over 300 periodic genes, with a focus on those required for cell proliferation in vivo. Finally, we investigate the role of novel genes required for interkinetic nuclear migration. Combined, these findings provide a global perspective on cell cycle control in vivo, and highlight a critical need to understand the context-specific regulation of cell proliferation.

Overall design: Transcriptional profiles of two RNAi knockdowns, CR32027-IR1 and CR32027-IR2, are examined in Drosophila wing pouch relative to OreR wt in triplicate by RNA Seq.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
This study employed Affymetrix GeneChips to profile transcriptome of human pulmonary microvascular endothelial cells (HMVEC-L) treated with PBEFsiRNA to gain insight into transcriptional regulations of PBEF on the endothelial function. We isolated and labeled mRNAs from PBEF siRNA transfected HMVEC-L and hybridized them to Affymetrix GeneChip HG-U133 plus 2. Differentially expressed genes and canonical pathways were analyzed. Expressions of selected genes were validated by RT-PCR or western blotting. Several important themes are emerged from this study. First, PBEF induces the upregulation and downregulation of multiple genes in the endothelium. Expression of 373 genes were increased and 64 genes decreased by at least 1.3 fold in the PBEFsiRNA treated group compared to the control group of PBEFscRNA treated HMVEC-L. Second, the microarray results confirmed some previous reports of PBEF mediated gene expressions in some pathways but provided a more complete repertoire of molecules in those pathways. Third, most of affected canonical pathways or differentially expressed genes in PBEF siRNA treated HMVEC-L over their controls have not previously been reported to be PBEF-responsive. Our first transcriptome analysis of human pulmonary microvascular endothelial cells treated with PBEFsiRNA has provided important insights into the transcriptional regulation of gene expression in HMVEC-L cells by PBEF. Further in-depth follow-up analysis of the transcriptional regulation reported in this study may shed light on molecular mechanisms underlying PBEF mediated endothelial functions and dysfunctions in the physiology and the pathogenesis of inflammatory conditions, cancer, diabetes, coronary heart disease and provide new leads of therapeutic targets to those diseases.

- Affymetrix Soybean Genome Array (soybean)
Description
Soybean is a rich source of protein and oil and a primary feedstock for biodiesel production. Previous research on soybean indicated that protein, oil and yield are controlled quantitatively in soybean seeds. However, genetic mechanisms controlling seed composition and yield in soybean remain unknown. We used Affymetrix Soybean GeneChips to identify genes that are differentially expressed between developing seeds of the Minsoy and Archer soybean varieties, which differ in seed weight, yield, protein content and oil content. Some of the differentially expressed genes identified in this study may play important roles in controlling these traits.

Description
Background: Personalized medicine is predicated on the notion that individual biochemical and genomic profiles are relatively constant in times of good health and to some extent predictive of disease or therapeutic response. We report a pilot study quantifying gene expression and methylation profile consistency over time, addressing the reasons for individual uniqueness, and its relation to N=1 phenotypes. Methods: Whole blood samples from 4 African American women, 4 Caucasian women, and 4 Caucasian men drawn from the Atlanta Center for Health Discovery and Well Being study at three successive 6-month intervals were profiled by RNASeq, miRNASeq, and Illumina Methyl-450 arrays. Standard regression approaches were used to evaluate the proportion of variance for each type of omic measure that is among individuals, and to quantify correlations among measures and with clinical attributes related to wellness. Results: Longitudinal omic profiles are in general highly consistent over time, with an average of 67% of the variance in transcript abundance, 42% of CpG methylation level (but 88% for the most differentiated CpG per gene), and 50% of miRNA abundance among individuals, which are all comparable to 74% of the variance among individuals for 74 clinical traits. One third of the variance can be attributed to differential blood cell type abundance, which is also fairly stable over time, and a lesser amount to eQTL effects, whereas seven conserved axes of covariance that capture diverse aspects of immune function explain over half of the variance. These axes also explain a considerable proportion of individually extreme transcript abundance, namely approximately 100 genes that are significantly up- or down-regulated in each person and are in some cases enriched for relevant gene activities that plausibly associate with clinical attributes. A similar fraction of genes have individually divergent methylation levels, but these do not overlap with the transcripts, and fewer than 20% of genes have significantly correlated methylation and gene expression. Conclusions: People express an “omic personality” consisting of peripheral blood transcriptional and epigenetic profiles that are constant over the course of a year and reflect various types of immune activity. Baseline genomic profiles can provide a window into the molecular basis of traits that might be useful for explaining medical conditions or guiding personalized health decisions. Overall design: Whole blood samples from 12 subjects drawn from the Atlanta Center for Health Discovery and Well Being study at three successive 6-month intervals were profiled by RNASeq, miRNASeq, and Illumina Methyl-450 arrays.
