Circadian expression of genes: modelling the Arabidopsis circadian clock

Project description:Our aim is to study the circadian expression of genes to aid in our attempt of modelling the Arabidopsis circadian clock. Circadian microarray data have previously been published for plants after white light (WL)-dark cycles, using the 8k chip (Harmer et al. 2000). We intend to repeat this experiment using the 26k chips and are coordinating with Dr. Harmer, who is pursuing complementary experiments in UC Davis. Plants will be transferred to continuous WL after entrainment to 12h:12h light dark cycles. RNAs will be harvested every 4 hours over two days, with the same accession and sampling intervals used previously by Harmer et al. The two days of sampling provide internal replication. Our experience shows that this is the most economical design: it is easier to identify rhythms over a two-day timecourse than in two replicates of a single day. Hence: 13 RNA samples on 13 chips in total. METHOD: Seed was sown on MS agar plates with 3% sucrose, imbibed at 4 C for 96 hours. Seed was then entrained for 7 days at 22C, in cycles of 12 hours white light, 12 hours darkness. After 7 days they were transferred to constant white light at 22 C: this is time 0h. Tissue harvested at the time points shown after time 0.

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.

A Minimal Circadian Clock Network for Glucose Tolerance in Mice

Project description:Physiology is regulated by interconnected cell and tissue circadian clocks. Disruption of the rhythms generated by this interconnectedness is associated with metabolic disease. Here we tested the interactions between clocks in two critical components of organismal metabolism – liver and skeletal muscle – by rescuing clock function either in each organ separately, or in both organs simultaneously, in otherwise clock-less mice. Experiments revealed that individual clocks are partially sufficient for tissue glucose metabolism, yet the connections between both tissue clocks coupled with daily feeding rhythms maximizes systemic glucose tolerance. This synergy relies in part on local transcriptional control of the glucose machinery, feeding-responsive signals such as insulin, and metabolic cycles that connect the muscle and liver. We posit that spatiotemporal mechanisms of muscle and liver play an essential role in the maintenance of systemic glucose homeostasis, and that disrupting this diurnal coordination can contribute to the metabolic disease.

Circadian clock controlled gene expression in soybean seeds

Project description:Microarray expression profiling was used to identify genes expressed in developing soybean (Glycine max) seeds that are controlled by the circadian clock. Plants with developing seeds were entrained to 12hour light: 12 hour dark cycles and sampled in constant light conditions.
