Description
Molecular mechanisms associated with pathophysiological variations in adipose tissue (AT) are not fully recognized. The main aim of this study was to identify novel candidate genes and miRNAs that may contribute to the pathophysiology of hyperplastic AT. Therefore, wide gene and microRNA (miRNA) expression patterns were assessed in subcutaneous AT of 16 morbidly obese women before and after surgery-induced weight loss. Validation of microarray data was performed by quantitative real-time PCR both longitudinally (n=25 paired samples) and cross-sectionally (25 obese vs. 26 age-matched lean women). Analyses in macrophages and differentiated human adipocytes were also performed to try to comprehend the associations found in AT. 5,018 different probe sets identified significant variations in gene expression after treatment (adjusted p-value<0.05). A set of 16 miRNAs also showed significant modifications. Functional analysis revealed changes in genes and miRNAs associated with cell cycle, development and proliferation, lipid metabolism, and the inflammatory response. Canonical affected pathways included TREM1, PI3K, and EIF2 signaling, hepatic stellate cell activation, and mitochondrial function. Increased expression of SLC27A2, ELOVL6, FASN, GYS2, LGALS12, PKP2, ACLY, and miR-575, as well as decreased FOS, EGFL6, PRG4, AQP9, DUSP1, RGS1, EGR1, SPP1, LYZ, miR-130b, miR-221, and miR-155, were further validated. The clustering of similar expression patterns for gene products with related functions revealed molecular footprints, some of them described for the first time, which elucidate changes in biological processes after the surgery-induced weight loss.

Description
This study demonstrates that arthritis and heart valve stenosis comorbidity, the most common condition among RA and SpA patients, share common mesenchymal requirements converging in the pathogenic activation of resident mesenchymal origin fibroblasts in the Tnf?ARE mouse model. TNFR2 signaling, in this context, orchestrates the molecular mechanisms underlying arthritis and heart valve stenosis manifestation by regulating fibroblasts pathogenic activation status, cell proliferation and pro-inflammatory milieu. Finally this work highlights the complexity of TNFR2 functions since mesenchymal signaling is detrimental, whereas systemic TNFR2 provides protective signals that contain both pathologies Overall design: 3' RNA-Seq (QuantSeq) profiling of 2 cell types (SFs,VICs) in two different genotypes (TNF-DeltaARE, ColVIp75f/f-TNF-DeltaARE) and Wild type as control. 3 replicates per group.

Description
During each life cycle germ cells preserve and pass on both genetic and epigenetic information. In C. elegans, the ALG-3/4 Argonaute (AGO) proteins and their small-RNA cofactors are expressed during male gametogenesis and promote male fertility. Here we show that the CSR-1 AGO functions with ALG-3/4 to positively regulate target genes required for spermiogenesis. Our findings suggest that ALG-3/4 functions during spermatogenesis to amplify a small-RNA signal that represents an epigenetic memory of male-specific gene expression, while CSR-1, which is abundant in mature sperm, transmits this memory to offspring. Surprisingly, in addition to small RNAs targeting male-specific genes, we show that males also harbor an extensive repertoire of CSR-1 small RNAs targeting oogenesis-specific mRNAs. Together these findings suggest that C. elegans sperm transmit not only the genome but also epigenetic binary signals in the form of Argonaute/small-RNA complexes that constitute a memory of which genes were active in preceding generations. Overall design: Examine small RNA changes in WT and alg-3/4 mutant males cultured at 20°C and 25°C, as well as determine the small RNAs enriched in a FLAG::CSR-1 IP from male worms grown at 25°C. mRNA sequencing was also performed to determine how transcripts targeted by small RNAs change in mutant background at 20°C and 25°C.

Description
The unfolded protein response (UPR) maintains endoplasmic reticulum (ER) proteostasis through the activation of transcription factors such as XBP1s and ATF6. The functional consequences of these transcription factors for ER proteostasis remain poorly defined. Here, we describe methodology that enables orthogonal, small molecule-mediated activation of the UPR-associated transcription factors XBP1s and/or ATF6 in the same cell independent of stress. We employ transcriptomics and quantitative proteomics to evaluate ER proteostasis network remodeling owing to the XBP1s and/or ATF6 transcriptional programs. Furthermore, we demonstrate that the three ER proteostasis environments accessible by activating XBP1s and/or ATF6 differentially influence the folding, trafficking, and degradation of destabilized ER client proteins without globally affecting the endogenous proteome. Our data reveal how the ER proteostasis network is remodeled by the XBP1s and/or ATF6 transcriptional programs at the molecular level and demonstrate the potential for selectively restoring aberrant ER proteostasis of pathologic, destabilized proteins through arm-selective UPR-activation.
