Description
Myasthenia gravis (MG) is a relatively rare autoimmune neuromuscular disorder. Monozygotic twin studies indicate that discordance rate in MG is about 70-60%, suggesting that despite identical DNA unknown factors contribute to disease development. The aim of the current study was to identify novel disease-associated genes in purified monocytes, including both genes associated with predisposition or with disease course, using the unique model of MZ twins. Thus the transcriptome and methylome were compared between twins discordant and concordant for the diseases, as well as MG singletons, and healthy controls. Several transcripts associated with immune homeostasis and inflammation resolution were highlighted in the current study. High similarity between the healthy and the MG discordant twins found, suggest that genetic predisposition may have a stronger contribution then previously assumed. In addition, results suggest that numerous small changes in expression and DNA methylation might contribute to disease onset making it more difficult to pick up

Description
Purpose: To identify transcriptional changes by RNA-seq in tumor samples, before bevacizumab combination treatment and after bevacizumab combination treatment in both responding and non-responding recurrent glioblastoma patients Overall design: Three comparison analyses were further performed: 1.) Paired analysis of pre- and post-treated samples from responding patients; 2.) Comparison of pre-treated samples of responders vs. non-responders; 3.) Paired analysis of pre- and post-treated samples from non-responding patients The sample ''characteristics: batch'' represents a combination of the RNA-extraction date and the library-preparation date for each sample.

Description
The perception that soy food products and dietary supplements will have beneficial effects on heart health has led to a massive consumer market. However, we have previously noted that diet has a profound effect on disease progression in a genetic model of hypertrophic cardiomyopathy (HCM). In this model, a soy-based diet negatively impacts cardiac function in male mice.

Description
We have generated a molecular taxonomy of lung carcinoma, the leading cause of cancer death in the United States and worldwide. Using oligonucleotide microarrays, we analyzed mRNA expression levels corresponding to 12,600 transcript sequences in 186 lung tumor samples, including 139 adenocarcinomas resected from the lung. Hierarchical and probabilistic clustering of expression data defined distinct subclasses of lung adenocarcinoma. Among these were tumors with high relative expression of neuroendocrine genes and of type II pneumocyte genes, respectively. Retrospective analysis revealed a less favorable outcome for the adenocarcinomas with neuroendocrine gene expression. The diagnostic potential of expression profiling is emphasized by its ability to discriminate primary lung adenocarcinomas from metastases of extra-pulmonary origin. These results suggest that integration of expression profile data with clinical parameters could aid in diagnosis of lung cancer patients.

Description
Ubiquitylation plays an important role in the control of Na+ homeostasis by the kidney. It is well established that the epithelial Na+ channel ENaC is regulated by the ubiquitin-protein ligase NEDD4-2, limiting ENaC cell surface expression and activity. Ubiquitylation can be reversed by the action of deubiquitylating enzymes (DUBs). One such DUB, USP2-45, was identified previously as an aldosterone-induced protein in the kidney, and is also a circadian output gene. In heterologous expression systems USP2-45 binds to ENaC, deubiquitylates it and enhances channel density and activity at the cell surface. Because the role of USP2-45 in renal Na+ transport had not been studied in vivo, we investigated here the effect of Usp2 gene inactivation in this process. We demonstrate first that the USP2-45 protein has a rhythmic expression with a peak at ZT12. Usp2-KO mice did not show any differences to wild-type littermates with respect to the diurnal control of Na+ or K+ urinary excretion and plasma levels neither on standard diet, nor after acute and chronic changes to low and high Na+ diets, respectively. Moreover, they had similar aldosterone levels either at low or high Na+ diet. Blood pressure measurements using telemetry did not reveal variations as compared to control mice. Usp2-KO did neither display alternations in ENaC or Na+,Cl--cotransporter (NCC) expression, nor were there any changes in regulatory protein levels, as evidenced by immunoblotting and transcriptome analysis. We conclude that USP2-45 is not crucial for the regulation of Na+ balance or maintenance of blood pressure in vivo.

Description
Plasmacytoid dendritic cells (pDCs) rapidly produce type I interferon (IFN-I) in response to viruses and are essential for antiviral immune responses. Although related to classical dendritic cells (cDCs) in their development and expression profile, pDCs possess many distinct features. Unlike cDCs, pDCs develop in the bone marrow (BM) and emerge into peripheral lymphoid organs and tissues as fully differentiated cells. We now report that pDCs specifically express Runx2, a Runt family transcription factor that is essential for bone development. Runx2-deficient murine pDCs developed normally in the BM but were greatly reduced in the periphery. The defect was cell-intrinsic and was associated with the retention of mature Ly49Q+ pDCs in the BM. Runx2 was required for the expression of several pDC-enriched genes including chemokine receptors Ccr2 and Ccr5. Mature pDCs expressed high levels of Ccr5 at the surface, and Ccr5-deficient pDCs in a competitive setting were reduced in the periphery relative to the BM. Thus, Runx2 is required for the emergence of mature BM pDCs into the periphery, in a process that is partially dependent on Ccr5. These results establish Runx2 as a lineage-specific regulator of immune system development.

Description
Samples collected from human subjects in clinical trials possess a level of complexity, arising from multiple cell types, that can obfuscate the analysis of data derived from them. Blood, for example, contains many different cell types that are derived from a distinct lineage and carry out a different immunological purpose. Failure to identify, quantify, and incorporate sources of heterogeneity into an analysis can have widespread and detrimental effects on subsequent statistical studies.
