Comparative transcriptome data of multi tissues in response to different environmental light-dark cycles

ABSTRACT: It is well known that host-microbes and immunity interactions are influenced by dietary patterns, as well as daily environmental light-dark (LD) cycles that entrain circadian rhythms in the host. Emerging data has highlighted the importance of diet patterns and timing on the interaction among circadian rhythms, gut microbiome, and immunity, however, their impacts on LD cycles are less reported. Therefore, we aim to study how LD cycles regulate the homeostatic crosstalk between gut microbiome, hypothalamic and hepatic circadian clock oscillations and immunity. We hypothesized that different environmental LD cycles: (1) constant darkness, LD0/24; (2) short light, LD8/16; (3) normal LD cycle, LD12/12; (4) long light, LD16/8; and (5) constant light, LD24/0, may affect immunity and metabolism to varying degrees. Therefore, 240 mice were managed with chow diets (CD) and antibiotics treatments (ABX) under five different LD cycles for 42 days. The liver (LIV), hypothalamus (HYP), inguinal white adipose tissue (iWAT), ileum epithelium (ILE), colon epithelium (COL), jejunum epithelium (JEJ), cecum epithelium (CEC), spleen (SPL), mammary gland (MAG), and thymus gland (THY) tissues were obtained for studying their impacts immunity using RNA-Seq data.

Light/dark- and temperature-regulated transcriptional rhythms in adult Caenorhabditis elegans

Project description: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. We used microarray experiments to identify light- and temperature-regulated transcriptional rhythms in C. elegans, and show that subsets of these transcripts are regulated in a circadian manner. In addition, we find that light and temperature also globally drive the expression of many genes, indicating that C. elegans exhibits systemic responses to these stimuli. Populations of growth-synchronized wild-type C. elegans L1 larvae were entrained for 5 days until adulthood to 12:12 hr light/dark (LD) cycles (500-1000 lux) at a constant temperature of 18°C, or for 4 days to 12:12 hr temperature cycles (25:15°C - warm/cold or WC) in constant darkness. RNA was collected every 4 hrs during the last entrainment and the subsequent free-running days and analyzed via hybridization of Affymetrix GeneChips. L4 larvae were transferred to FUDR-containing plates to inhibit embryonic development.

Genome-wide profiling of diel and circadian gene expression of the malaria vector Anopheles gambiae

Project description: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. gambiae head and bodies under 12:12 light:dark cycle (LD) and constant dark (DD, free-running) conditions. Zeitgeber Time (ZT) with ZT12 defined as time of lights OFF under the light:dark cycle, and ZT0 defined as end of the dawn transition. Circadian Time (CT) with CT0 defined as subjective dawn, inferred from ZT0 of the previous light:dark cycle. Adult mated but non-blood fed female mosquito heads and bodies under 12:12 light:dark cycle (LD) and constant dark (DD) conditions were collected every 4 hr to generate 48 hr gene expression profiles, and samples were processed with Affymetrix full genome microarrays. Downstream analysis identified genes with ~24hr rhythmic expression profiles.

transcriptional analysis of breast circadian clock

Project description:Circadian clocks drive ~24 hr rhythms in tissue physiology. They rely on transcriptional/translational feedback loops driven by interacting networks of clock complexes.To gain insights into the role of the mammary clock, circadian time-series microarrays were performed to identify rhythmic genes in vivo. Breast tissues were isolated at 4 hr intervals for two circadian (24 hourly) cycles, from mice kept under constant darkness to avoid any light- or dark-driven genes.

Dietary tryptophan and circadian rhythms in the Liver

Project description:Mice were fed a normal chow diet or a tryptophan depleted diet for two weeks under normal 12-hr light/dark cycles (LD) or in constant darkness (DD). Mice were sacrificed every 4th hour over the 24-hr circadian cycle. The liver was harvested and RNA was isolated using a standard TRIZOL protocol. The data suggest that dietary tryptophan is an important component of the diet regulating circadian homeostsis.

Transcription profiling of Arabidopsis to identify of circadian-regulated genes

Project description:Most higher organisms, including plants and animals, have developed a time-keeping mechanism that allows them to anticipate daily fluctuations of environmental parameters such as light and temperature. This circadian clock efficiently coordinates plant growth and metabolism with respect to time-of-day by producing self-sustained rhythms of gene expression with an approximately 24-hour period. The importance of these rhythms has in fact been demonstrated in both phytoplankton and higher plants: organisms that have an internal clock period matched to the external environment possess a competitive advantage over those that do not. We used microarrays to identify circadian-regulated genes of Arabidopsis thaliana to elucidate how the clock provides an adaptive advantage by understanding how the clock regulates outputs and determining which pathways and processes may be under circadian control. Experiment Overall Design: Groups of Arabidopsis seedlings were grown in light/dark cycles for 7 d before, transferred to constant light, and after 24 h in constant light 12 samples were harvested at 4-h intervals over the next 44 h for RNA extraction and hybridization on Affymetrix microarrays.

Temporal expression data from zebrafish pineal gland

Project description:Microarray data allowed detection of genes that have circadian expression pattern in the zebrafish pineal gland Adult (0.5-1.5 years old) transgenic zebrafish, Tg(aanat2:EGFP)Y8, which express enhanced green fluorescent protein (EGFP) in the pineal gland under the control of the aanat2 regulatory regions, were used. Fish were raised under 12-hr light:12-hr dark (LD) cycles, in a temperature controlled room, and transferred to constant darkness (DD) for tissue collection. Fish were anesthetized in 1.5 mM Tricane (Sigma), sacrificed by decapitation, and pineal glands were removed under a fluorescent dissecting microscope. Starting from circadian time (CT) 14, pineal glands were collected at 4-hr intervals for 48 hours (12 time points identified as CT 14, 18, 22, 2, 6, 10, 14b, 18b, 22b, 2b, 6b and 10b). Pools of 12 pineal glands were prepared at each time-point and total RNA was extracted using the RNeasy Lipid Tissue Mini Kit (QIAGEN), according to the manufacturer's instructions.

Analysis of the circadian transcriptome of the Antarctic krill Euphausia superba

Project description:Antarctic krill (Euphausia superba) is a high latitude pelagic organism which plays a central role in the Southern Ocean ecosystem. E. superba shows daily and seasonal rhythms in physiology and behaviour, which are synchronized with the environmental cycles of its habitat. Recently, the main components of the krill circadian machinery have been identified and characterized. However, the exact mechanisms through which the endogenous timing system operates the control and regulation of the overt rhythms remains only partially understood. Here we investigate the involvement of the circadian clock in the temporal orchestration of gene expression by using a newly developed version of a krill microarray platform. The analysis of transcriptome data from krill exposed to both light-dark cycles (LD 18:6) and constant darkness (DD), has led to the identification of 1,564 putative clock-controlled genes. A remarkably large proportion of such genes, including several clock components (clock, period, cry2, vrille, and slimb), show oscillatory expression patterns in DD, with a periodicity shorter than 24 hours. Energy-storage pathways appear to be regulated by the endogenous clock in accordance with their ecological relevance in daily energy managing and overwintering. Our results provide the first representation of the krill circadian transcriptome under laboratory, free-running conditions. This SuperSeries is composed of the SubSeries listed below.
