Description
Plants respond to changes in the red:far red ratio (R:FR) of incident light. A reduction in this ratio (increase in FR) results in the Shade Avoidance Response (SAR) with associated changes in gene expression. The Phyotchrome-Interacting Factors (PIFs) are bHLH transcription factors known to be involved in the SAR. An analysis of changes in gene expression in WT and quadruple pif1pif3pif4pif5 (pifq; Leivar et al., 2008 (PMID 19920208)) mutant seedlings in response to an increase in FR should identify primary targets of PIF signaling.

Description
Light initiates the seedling deetiolation transition by promoting major changes in gene expression mainly regulated by phytochrome (phy) photoreceptors. During the initial dark-to-light transition, phy photoactivation induces rapid changes in gene expression that eventually lead to the photomorphogenic development. Recent reports indicate that this process is achieved by phy-induced degradation of Phy-Interacting bHLH transcription Factors (PIFs) PIF1, PIF3 PIF4 and PIF5, which are partly redundant constitutive repressors of photomorphogenesis that accumulate in darkness. In order to test whether light/phy-regulated gene expression occurs through these PIFs, we have performed whole-genome expression analysis in the pif1pif3pif4pif5 quadruple mutant (pifq).

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.
