(Submitter supplied) Odor discrimination behavior displays circadian fluctuations in mice indicating that mammalian olfactory function is under control of the circadian system. This is further supported by the facts that odor discrimination rhythms depend on the presence of clock genes and that olfactory tissues contain autonomous circadian clocks. However, the molecular link between circadian function and olfactory processing is still unknown. 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) Mammalian gene expression displays widespread circadian oscillations. Rhythmic transcription underlies the core clock mechanism, but it cannot explain numerous observations made at the level of protein rhythmicity. We have used ribosome profiling in mouse liver to measure the translation of mRNAs into protein around-the-clock and at high temporal and nucleotide resolution. Transcriptome-wide, we discovered extensive rhythms in ribosome occupancy, and identified a core set of ≈150 mRNAs subject to particularly robust daily changes in translation efficiency. more...

(Submitter supplied) Identification of all genes expressed by mouse olfactory sensory neurons; genes expressed in mature neurons, immature neurons, or both were distinguished. Independent validation of enrichment ratio values supported by statistical assessment of error rates was used to build a database of statistical probabilities of the expression of all mRNAs detected in mature neurons, immature neurons, both types of neurons (shared), and the residual population of all other cell types. more...

(Submitter supplied) Anopheles gambiae, the primary African malarial mosquito, exhibits numerous behaviors that are under diel and circadian control, including locomotor activity, swarming, mating, host seeking, eclosion, egg laying and sugar feeding. However, little has been performed to elucidate the molecular basis for these daily rhythms. To study how gene expression is globally regulated by diel and circadian mechanisms, we have undertaken a DNA microarray analysis of A. more...

(Submitter supplied) Physiological and behavioral circadian rhythms are driven by a conserved transcriptional/translational negative feedback loop in mammals. Although most core clock factors are transcription factors, post-transcriptional control introduces delays that are critical for circadian oscillations. Little work has been done on circadian regulation of translation, so to address this deficit we conducted ribosome profiling experiments in a human cell model for an autonomous clock. more...

(Submitter supplied) Disruption of the circadian clock, which directs rhythmic expression of numerous genes, accelerates aging. To inquire how the circadian system protects organisms during aging, we compared circadian transcriptomes in heads of young and old Drosophila melanogaster. These data revealed a class of genes that adopt de novo rhythmicity during aging, termed "late life cyclers" (LLCs). We show that application of exogenous oxidative stress in young flies mimics aging by inducing robust, rhythmic LLC upregulation in a light- and CLOCK-dependent fashion. more...

(Submitter supplied) This study explores the impact of disrupting the circadian clock through a Cycle gene knockout (KO) on the transcriptome of Aedes aegypti mosquitoes. The investigation aims to uncover the resulting alterations in gene expression patterns and physiological processes. Transcriptome analysis was conducted on Cyc knockout (AeCyc-/-) and wild-type mosquitoes at four time points in a light-dark cycle. The study identified system-driven genes that exhibit rhythmic expression independently of the core clock machinery. more...
