Description
MicroRNA-offset RNAs (moRs) were first identified in simple chordates and subsequently in mouse and human cells by deep sequencing of short RNAs. MoRs are derived from sequences located immediately adjacent to microRNAs (miRs) in the primary miR (pri-miR). Currently moRs are considered to be simply a by-product of miR biosynthesis that lack biological activity. Here we show for the first time that a moR is biologically active. We now demonstrate that endogenous and over-expressed moR-21 significantly alters gene expression and inhibits the proliferation of vascular smooth muscle cells (VSMC). We report that the seed region of moR-21 as well as the seed match region in the target gene 3'UTR are indispensable for moR-21-mediated gene down-regulation. We further demonstrated that moR-21-mediated gene repression is Argonaute 2 (Ago2) dependent. In addition, we find that miR-21 and moR-21 may regulate different genes in a given pathway and can oppose each other in regulating certain genes. Taken together, these findings provide the first evidence that microRNA offset RNA regulates gene expression and is biologically active.

Description
We used morpholinos and gene editing tools to inactivate the srsf5a gene. In contrast to srsf5a homozygous mutants that did not display any phenotypic traits, microinjection of sMOsrsf5a led to developmental defects. By using RNA sequencing on morphants and control embryos we were able to identify a plethora of morpholino inadvertant target. Overall design: Two biological replicates were used per conditions. Samples named CtrlMO consist in embryos injected with the control morpholino (5''-CCTCTTACCTCAGTTACAATTTATA-3'', Gene Tools). Samples named sMOsrsf5a consist in embryos injected with the morpholino against srsf5a (5''-GGATTCAGTCTCACCTCTCACTGCA-3'', Gene Tools).

Description
The goal of this study was to identify the molecular characteristics and putative markers distinguishing IL-10eGFP+CD138hi and IL-10eGFP-CD138hi plasmocytes. To this end, IL-10eGFP B-green mice were challenged intravenously with Salmonella typhimurium (strain SL7207, 10e7 CFU), and IL-10eGFP+CD138hi as well as IL-10eGFP-CD138hi plasmocytes were isolated from the spleen on the next day. For this, single cell suspensions were prepared, cells were treated with Fc block (10 g/ml, anti-CD16/CD32, clone 2.4G2), and then stained with an antibody against CD138 conjugated to PE (1/400; from BD Pharmingen) followed by incubation with anti-PE microbeads (Miltenyi Biotech). CD138+ cells were then enriched on Automacs (Miltenyi Biotech) using the program possel_d2. Cells were then stained with anti-CD19-PerCP, anti-CD138-PE, and antibodies against CD11b, CD11c, and TCR conjugated to APC as a dump channel to exclude possible contaminants. DAPI was added to exclude dead cells. Live IL-10eGFP+CD138hi and IL-10eGFP-CD138hi cells were subsequently isolated on a cell sorter. The purity of the samples was always above 98%. This led to the identification of LAG-3 as a cell surface receptor specifically expressed on IL-10eGFP+CD138hi cells but not on IL-10eGFP-CD138hi cells.

Description
There are an estimated 21million diabetics in the United States and 150 million diabetics worldwide. The World Health Organization anticipates that these numbers will double in the next 20 years. Metabolic syndrome is a well recognized set of symptoms that increases a patients risk of developing diabetes. Insulin resistance is a factor in both metabolic syndrome and Type 2 diabetes. It is characterized by decreased insulin stimulated glucose uptake in peripheral tissues, decreased adiponectin levels, increased adipocyte FFA and cytokine production, and increased insulin and hepatic glucose output. Prevention or reversal of insulin resistance should serve as an important strategy in addressing the growing health concerns posed by the Diabetes epidemic. While increased adiposity is associated with insulin resistance, the role of the cell types present within adipose (adipocytes, pre-adipocytes, endothelial cells, macrophages, fibroblasts, leukocytes and smooth muscle cells) in insulin resistance is unclear. In an effort to begin dissection of this question, we examined the transcriptional response of the buoyant and non-buoyant fractions isolated from insulin sensitive or TNF induced insulin resistant hMSC derived adipocytes before and after treatment with insulin.

Description
The aim of this study was to characterize expression profiles of visceral and subcutaneous adipose tissue in children. Adipose tissue samples were collected from children having elective surgery (n=71, [54 boys], 6.0 +- 4.3 years). Affymetrix microarrays (n=20) were performed to characterize the functional profile and identify genes of interest in adipose tissue. Visceral adipose tissue had an overrepresentation of Gene Ontology themes related to immune and inflammatory responses and subcutaneous adipose tissue had an overrepresentation of themes related to adipocyte growth and development. Likewise, qPCR performed in the whole cohort showed a 30-fold increase in haptoglobin (P < 0.005), 7-fold increase in IL-10 (P < 0.001), 8-fold decrease in VEGF (P < 0.01) and a 28-fold decrease in TBOX15 (P < 0.001) in visceral compared to subcutaneous adipose tissue.The inflammatory pattern in visceral adipose tissue may represent an early stage of the adverse effects of this depot, and combined with chronic obesity, may contribute to increased metabolic and cardiovascular risk.

Description
Regulatory T cells (Tregs) play a cardinal role in the immune system by suppressing detrimental autoimmune responses, but their role in acute and chronic infectious diseases remains unclear. We recently demonstrated that IFN-??? receptor (IFNAR) signaling promotes Treg function in autoimmunity. To dissect the functional role of IFNAR-signaling in Tregs during acute and chronic viral infection, we infected Treg-specific IFNAR deficient (IFNARfl/flxFoxp3YFP-Cre) mice with LCMV Armstrong and Clone-13. In both models, IFNARfl/flxFoxp3YFP-Cre mice Tregs expressed enhanced expression of Treg associated activation antigens. The enhanced activated phenotype was also seen when we compared the transcriptomes of IFNARfl/flxFoxp3YFP-Cre and wild type (WT) Tregs by RNA-Seq on day 25-post Clone-13 infection. LCMV-specific CD8+ T cells from IFNARfl/flxFoxp3YFP-Cre mice produced less antiviral IFN? and TNF? in both acute and chronic LCMV. In the chronic model, the numbers of anti-viral effector and memory CD8+ T cells were decreased in IFNARfl/flxFoxp3YFP-Cre mice and the effector CD4+ and CD8+ T cells exhibited a phenotype compatible with enhanced exhaustion. IFNARfl/flxFoxp3YFP-Cre mice cleared Armstrong infection normally, but had higher viral titers in sera, kidneys and lungs than WT mice during chronic infection. Thus, type I IFN signaling in Tregs is context-dependent, resulting in enhanced suppressor function in some models of autoimmunity, but decreased suppressor function in acute and chronic viral infection. Overall design: mRNA from Treg cells from 5 WT and 5 IFNAR deficient mice were analyzied by RNA-seq using Illumina HiSeq

Description
Background: Clinical trial and epidemiological data support that the cardiovascular effects of estrogen are complex, including a mixture of both potentially beneficial and harmful effects. In animal models, estrogen protects females from vascular injury and inhibits atherosclerosis. These effects are mediated by estrogen receptors (ERs), which when bound to estrogen can bind to DNA to directly regulate transcription. ERs can also activate several cellular kinases by inducing a rapid non-nuclear signaling cascade. However, the biologic significance of this rapid signaling pathway has been unclear.
Publication Title
Rapid estrogen receptor signaling is essential for the protective effects of estrogen against vascular injury.

Description
A comparison of the translating RNAs in UCP1-positive cells from the classical BAT, the inguinal WAT, and the perigonadal WAT. We find genes common to all UCP1-positive cells independent of anatomical location, as well as genes specifically enriched in one group versus the others. Results provide a portrait of gene expression in UCP1-positive cells in vivo. Overall design: Translating RNAs in UCP1-positive cells were purified from 6 week old female UCP1-TRAP mice after 2 weeks at 4 degC. N=3 for iWAT, N=2 for pgWAT, and N=3 for BAT.
