Description
Adipogenesis involves the regulation of hundreds of genes by several well-studied proteins, but the role of long, noncoding RNAs in this process has not been defined. We track the regulation of hundreds of lncRNAs during adipocyte differentiation, and find several that are essential for this process.

Description
Adipogenesis involves the regulation of hundreds of genes by several well-studied proteins, but the role of long, noncoding RNAs in this process has not been defined. We track the regulation of hundreds of lncRNAs during adipocyte differentiation, and find several that are essential for this process. Overall design: We extractedbrown and white primary adipocytes and pre-adipocytes and profiled lncRNA expresssion via mRNA-Seq. We also profiled cultured, differentiated adipocytes to verify that we could recapitulate the adipocyte expression profile in preparation for a loss-of-function screen for essential adipogenic lincRNAs.

Description
Compelling evidence suggests that mitochondrial dysfunction contributes to the pathogenesis of heart failure, including defects in the substrate oxidation, and the electron transport chain (ETC) and oxidative phosphorylation (OXPHOS). However, whether such changes occur early in the development of heart failure, and are potentially involved in the pathologic events that lead to cardiac dysfunction is unknown. To address this question, we conducted transcriptomic/metabolomics profiling in hearts of mice with two progressive stages of pressure overload-induced cardiac hypetrophy: i) cardiac hypertrophy with preserved ventricular function achieved via transverse aortic constriction for 4 weeks (TAC) and ii) decompensated cardiac hypertrophy or heart failure (HF) caused by combining 4 wk TAC with a small apical myocardial infarction. Transcriptomic analyses revealed, as shown previously, downregulated expression of genes involved in mitochondrial fatty acid oxidation in both TAC and HF hearts compared to sham-operated control hearts. Surprisingly, however, there were very few changes in expression of genes involved in other mitochondrial energy transduction pathways, ETC, or OXPHOS. Metabolomic analyses demonstrated significant alterations in pathway metabolite levels in HF (but not in TAC), including elevations in acylcarnitines, a subset of amino acids, and the lactate/pyruvate ratio. In contrast, the majority of organic acids were lower than controls. This metabolite profile suggests bottlenecks in the carbon substrate input to the TCA cycle. This transcriptomic/metabolomic profile was markedly different from that of mice PGC-1a/b deficiency in which a global downregulation of genes involved in mitochondrial ETC and OXPHOS was noted. In addition, the transcriptomic/metabolomic signatures of HF differed markedly from that of the exercise-trained mouse heart. We conclude that in contrast to current dogma, alterations in mitochondrial metabolism that occur early in the development of heart failure reflect largely post-transcriptional mechanisms resulting in impedance to substrate flux into the TCA cycle, reflected by alterations in the metabolome.

Description
While activation of canonical NF-?B signaling through the IKK complex is well studied, few regulators of NIK-dependent non-canonical p52 nuclear translocation have been identified. We discovered a novel role for cyclin dependent kinase 12 (CDK12) in transcriptionally regulating the non-canonical NF-?B pathway. High-content phenotypic screening identified a novel compound, 919278, which inhibits lymphotoxin ß receptor (LTßR)- and FN14-dependent p52 nuclear translocation, but not TNFa receptor (TNFR)-mediated, canonical NF-?B p65 nuclear translocation. Chemoproteomics identified cyclin dependent kinase 12 (CDK12) as the target of 919278. CDK12 inhibition by 919278, THZ1, or siRNA knock down all affect similar global transcriptional changes and prevent LTßR and FN14-dependent MAP3K14 (NIK) mRNA induction and subsequent protein accumulation. In addition, 919278 and THZ1 treatment reduce RNA Pol II CTD phosphorylation. This powerful approach of coupling a phenotypic screen with chemoproteomics revealed a novel regulatory pathway of the non-canonical NF-?B pathway that could serve as a therapeutic target in autoimmunity and cancer. Overall design: There are TWEAK stimulated and unstimulated conditions, 4hr and 24hr time points. 7 treatments (DMSO, BIO0702697, BIO0919278, BIO032202, NTsiRNA, siRNAs523626, siRNAs523629) in duplicates. In total, 56 sample were sequenced and analyzed.

Description
Single cell RNAseq analysis of hair cells isolated from the mouse utricle at three postnatal time points Overall design: Utricular hair cells were isolated at P12 (49 cells) and P100 (23 cells) and then combined with a previously published single cell data set (samples from GSE71982) containing 35 utricular hair cells isolated at P1 (Burns et al., 2015) The previously published single cell P1 samples have been re-normalized. These samples are included in this series and all processed data are available in the file ute_normalized_data.txt, available at the foot of this record.
