(Submitter supplied) To screen for specific circadian outputs that may distinguish the pacemaker in the mammalian suprachiasmatic nucleus (SCN) from peripheral-type oscillators in which the canonical clockworks are similarly regulated in a circadian manner, the rhythmic behavior of the transcriptome in forskolin-stimulated NIH/3T3 fibroblasts was analyzed and compared to that found in the rat SCN in vivo and SCN2.2 cells in vitro. more...

(Submitter supplied) Systemic administration of β-adrenoceptor (β-AR) agonists has been found to induce skeletal muscle hypertrophy and significant metabolic changes. In the context of energy homeostasis, the importance of β-AR signaling has been highlighted by the inability of β1–3-AR-deficient mice to regulate energy expenditure and susceptibility to diet induced obesity. However, the molecular pathways and gene expression changes that initiate and maintain these phenotypic modulations are poorly understood. more...

(Submitter supplied) One hundred ninety wildtype male C57BL/6J mice age 7-10 weeks were purchased from Jackson Laboratory and entrained to a 12:12 light:dark cycle for 2 weeks. Mice were placed in light-tight boxes on a 12:12 LD cycle for 4 weeks, then released into constant darkness. Starting 30 hours after entry into DD (CT18), tissues from 5 (skeletal muscle) or 10 (liver or SCN) wildtype mice were collected every 4 hours for 48 hours, for a total of 12 timepoints. more...

(Submitter supplied) In intact animals, time of drug administration may be an important factor influencing drug response. Our general goal seeks to incorporate circadian time into the study of corticosteroid regulated gene expression. This study is designed to examine fluctuations in gene expression in skeletal muscle within the 24 hour circadian cycle in normal animals. Circadian time is relevant to designing optimal corticosteroid dosing regimens. more...

(Submitter supplied) Background: Muscle responses to exercise are complex, and potentially include acute responses to exercise-induced injury as well as longer-term adaptive training responses. Using Alaskan sled dogs as an experimental model, changes in muscle gene expression were analyzed to better understand the temporal changes that occur after severe exercise. Methods: Dogs were randomly assigned to undertake in a 160 km run (n=9), or to remain at rest (n=4). more...

(Submitter supplied) Physical performance relies on the concerted action of myriad responses, many of which are under circadian clock control. Little is known, however, regarding the time-dependent effect on exercise performance at the molecular level. We found that both mice and humans exhibit day-time variance in exercise capacity between the early and late part of their active phase. The day-time variance in mice was dependent on exercise intensity and relied on the circadian clock proteins PER1/2. more...

(Submitter supplied) We performed the circadian transcriptome analysis using the skeletal muscle from sedentary and exercised mice either in the early rest phase (ZT3) or in the early active phase (ZT15). By the combination with circadian transcriptomic and metabolomic analysis, we revealed time-of-day-dependent remodeling of circadian muscular metabolic pathways involved in glucose and glycerol metabolism after exercise. more...

(Submitter supplied) Physical exercise triggers numerous positive adaptations through the regulation of genes controlling muscle structure and function. Epigenetic factors like DNA methylation participate in transcriptional activation by allowing the recruitment of the transcription machinery to gene promoters. Exercise induces dynamic DNA demethylation at gene promoters, but the contribution of the demethylation precursor hydroxymethylcytosine is unknown. more...

(Submitter supplied) The time course of wound healing or the estimation of wound age is one of the most important research subjects in forensic pathology. In this study, we obtained microarray data of incision injury samples of mouse skeletal muscle at 3 different time points post-injury (6, 12, and 24 h). To visualize the time course fluctuation in gene expression on a plot, and to examine large-scale data using various analytical methods, correspondence analysis (CA) was carried out on microarray data that was converted to a matrix (data type is fold change (FC) values) consisting of data of each time point (columns) by each gene (rows) as variables. more...
