Description
We show that key regulators of oxidative metabolism, the Estrogen Related Receptors (ERRs) and the PGC-1 co-activators, are transiently induced during somatic cell reprogramming. Bioenergetic assays reveal that while glycolysis increases throughout the reprogramming transition, the early stages feature a transient oxidative phosphorylation (OXPHOS) burst. Up-regulation of ERRa or ? is a prerequisite for the OXPHOS burst in human and mouse cells, respectively, and failure to induce this metabolic switch collapses the reprogramming process. We identify a Sca1-/CD34- sub-population of early reprogramming cells with enhanced ERR? and PGC-1ß expression as bona fide reprogramming progenitors. Transcriptional profiling confirmed that these progenitors have undergone extensive metabolic reprogramming. These studies characterize a previously unrecognized, ERR-dependent metabolic switch prior to establishment of induced pluripotency.

Background: Moderate hypothermia (32oC for 12 72 hours) has therapeutic applications, but the mechanisms by which it affects cellular function are unclear. We tested the hypothesis that moderate hypothermia produces broad changes in gene expression by human cells at the level of mRNA.

Description
Allergen exposure induces the airway epithelium to produce chemoattractants, proallergic interleukins, matrix-modifying proteins, and proteins that influence the growth and activation state of airway structural cells. These proteins, in turn, contribute to the influx of inflammatory cells and changes in structure that characterize the asthmatic airway. To use the response of the airway epithelium to allergen to identify genes not previously associated with allergic responses, we compared gene expression in cytokeratin-positive cells before and after segmental allergen challenge. After challenge with concentrations of allergen in the clinically relevant range, 755 (6%) of the detectable sequences had geometric mean fold-changes in expression, with 95% confidence intervals that excluded unity. Using a prospectively defined conservative filtering algorithm, we identified 141 sequences as upregulated and eight as downregulated, with confirmation by conventional polymerase chain reaction in all 10 sequences studied. Using this approach, we identified asthma-associated sequences including interleukin (IL-)-3, IL-4, and IL-5 receptor subunits, the p65 component of nuclear factor-kappaB, and lipocortin. The genomic response of the human airway to concentrations of allergen in the clinically relevant range involves a greater number of genes than previously recognized, including many not previously associated with asthma that are differentially expressed after airway allergen exposure.

Description
We show that fat-resident regulatory T cells, termed fTregs, drive age-associated insulin resistance and can be specifically depleted to increase adipose insulin sensitivity. Comparative AdipoImmune profiling in young, aged, and obese mice reveals that fTregs progressively enrich in adipose as a function of age, but not obesity. fTreg-deficient mice are protected from age-associated insulin resistance and its accompanying physiological hallmarks. In contrast, fTreg-deficiency offers no protection from obesity-associated insulin resistance.

Description
To investigate the paracrine effects of stromal elements on cancer cells, we developed a “stromal” culture system, which incorporates structural and diffusible stroma-derived elements into homotypic cultures amenable to functional genomics and metabolomics. Here we show that microenvironmental cues co-regulate cancer metabolism and gene expression. Stromal inputs broadly influenced histone acetylation in the cancer epigenome, which coincided with induction of genes implicated in anabolic metabolism and inflammation. The gene expression and metabolic changes induced by stromal factors overlap with those previously identified following oncogenic Kras, suggesting functional complementarity between cell-autonomous and microenvironmental pathways. Finally, we implicate the BET family of epigenetic readers as key transducers of stromal inputs to drive alterations in gene expression. This work suggests paracrine epigenome regulation as a conduit through which stromal signals drive metabolic and immune adaptation to a challenging tumor microenvironment.

Description
We report that Rev-erba is targeted for ubiquitination and subsequent degradation by the F-box protein Fbxw7a, and identify the cyclin-dependent kinase 1 (Cdk1)-mediated phosphorylation of threonine 275 as necessary for the recruitment of the Fbxw7-dependent E3 ligase complex. In vitro, inhibition of Cdk1 kinase activity or mutation of T275 is sufficient to disrupt the Fbxw7-mediated Rev-erba degradation pathway. Moreover, genetic disruption of Fbxw7 in mouse liver dramatically alters the circadian expression of core clock genes and perturbs whole body lipid and glucose levels. These results reveal an additional level of regulation required for maintaining circadian rhythmicity, and reveal the essential roles of post-translational modifications in the coordination of the circadian clocks and metabolism through regulation of nuclear receptor protein stability.
