(Submitter supplied) Circadian clocks are temporally aligned to the environment via signals, or Zeitgebers, such as daily light and temperature cycles, food availability, and social behavior. In this study, we show that genome-wide expression profiles from temperature-entrained flies show a dramatic difference in the presence or absence of a thermocycle. Whereas transcription appears to be modified globally by changes in temperature, there is a specific set of transcripts that continue to oscillate in constant conditions following temperature entrainment. more...

(Submitter supplied) Study on differential gene expression and splicing between wildtype and clock mutants. This study is part of a comparative analysis of the role of Protein Methyltransferase 5 in the regulation of transcriptional and post-transcriptional processes simultaneously in Arabidopsis and Drosophila. Circadian rhythms allow organisms to time biological processes to the most appropriate phases of the day/night cycle1. more...

(Submitter supplied) Most organisms have an endogenous circadian clock that is synchronized to environmental signals such as light and temperature. Although circadian rhythms have been described in the nematode C. elegans at the behavioral level, these rhythms appear to be relatively non-robust. Moreover, in contrast to other animal models, no circadian transcriptional rhythms have been identified. Thus, whether this simple nematode contains a bona fide circadian clock remains an open question. more...

(Submitter supplied) The circadian clock is an evolutionarily conserved mechanism that drives rhythmic expression of downstream genes. The core circadian clock drives the expression of clock-controlled genes either directly or indirectly, which in turn play critical roles in carrying out many rhythmic physiological processes. Nevertheless, the molecular mechanisms by which clock output genes orchestrate rhythmic signals from the brain to peripheral tissues are largely unknown. more...

(Submitter supplied) The spliceosome is a dynamic RNA-protein complex that executes pre-mRNA splicing and is composed of five core small nuclear ribonucleoprotein particles (U1, U2, U4/5/6 snRNP) and >150 additional proteins specific for each snRNP. We report a circadian role for Pre-mRNA Processing factor 4 (PRP4), a conserved component of the spliceosomal U4/U6.U5 triple small nuclear ribonucleoprotein (tri-snRNP) complex. more...

(Submitter supplied) We utilized the Nematostella vectensis to quantify gene expression differences and loss during light:dark cycling and immediately after light cue removal through comparisons of 136 transcriptomes Organismal responses to light:dark cycles can result from two general processes: (i) direct response to light or (ii) a free-running rhythm (i.e., a circadian clock). Previous research in cnidarians has shown that candidate circadian clock genes have rhythmic expression in the presence of diel lighting, but these oscillations appear to be lost quickly after removal of the light cue. more...

(Submitter supplied) Eukaryotic circadian clocks include transcriptional/translational feedback loops that drive 24-hour rhythms of transcription.These transcriptional rhythms underlie oscillations of protein abundance, thereby mediating circadian rhythms of behavior, physiology, and metabolism. Numerous studies over the last decade have employed microarrays to profile circadian transcriptional rhythms in various organisms and tissues. more...

(Submitter supplied) Gene expression profiling of distinct members of a neuronal circuit has the potential to identify candidate molecules and mechanisms that underlie the formation, organization and function of the circuit. To this end, we report here the application of a novel method to characterize RNAs from small numbers of specific Drosophila brain neurons, which belong to the circadian circuit. We identified three different sets of mRNAs enriched in different subclasses of clock neurons: one is enriched in all clock neurons, a second is enriched in PDF-positive clock neurons and a third is enriched in PDF-negative clock neurons. more...
