PolyA RNA sequencing of soleus muscles of WT and LSD1-mKO mice after voluntary wheel running

Project description:To understand the role of LSD1 in transcriptional regulation in muscle under voluntary wheel running (VWR) training, RNA-seq analyses of soleus muscles of skeletal muscle-specific LSD1 KO mice (LSD1-mKO mice) and WT mice after VWR were carried out. We found that loss of LSD1 led to increased expression of oxidative metabolism genes in soleus muscle.

Effect of wheel running exercise on gene expression in skeletal muscles of mice

Project description:This analysis was done to determine which muscle group has the most skeletal muscle transcriptional reponses to wheel running activity. Seven male mice with C57BL/6 genetic background were placed individually in cages with running wheels and allowed free access to the wheels 24 hr per day. Access to running wheels began when the mice were 6 months old, and continued for 12 weeks. The morning after the night of running, the mice were euthanized and several muscle groups were snap froze in liquid nitrogen to preserve RNA. The same muscle groups were collected from three age-matched "sedentary" mice that were housed in ordinary cages that did not permit sustained running. For each muscle group, separate pools of polyadenylated RNA from the sedentary and wheel-running mice were prepared for deep sequencing of cDNA with the SOLiD 3 platform. Four muscle groups were examined (quadriceps femoris; gastrocnemius/plantaris; tibialis anterior; triceps brachii). For each muscle, RNA was pooled from 3 sedentary or 7 wheel-running mice (8 pools total).

RNA-Seq of effects of exercise-induced Extracellular Vesicles on an F344 rat (Rattus norvegicus) model of forced running wheel exercise

Project description:n total, 16 7-week-old male F344 rats were subjected to model regular exercise and sedentary lifestyle. In the second week after arrival and acclimatization to the reversed light/dark cycle, rats were introduced to the forced running wheel without a specific running mode. It was followed by a 12-day training phase for all 16 experimental animals (started at 9 weeks of age) by gradually increasing the running speed and duration. During the training phase, 8 best performers were selected for the runner group while the remaining 8 rats were assigned to the sedentary group. The regular forced running exercise phase for the runner group lasted for 5 weeks in total, including 4 weeks of regular running. After 4 weeks of regular exercise, rats underwent brief anesthesia and of blood from the tail vein were taken. This step was repeated for the same animals immediately after 1h of running. On the same day, a blood sample was collected from the sedentary rats following the same protocol. Plasma was collected and immediately frozen for further EV isolation. EVs were isolated from rat plasma by size exclusion chromatography. RNA libraries were constructed using CleanTag® Small RNA Library Prep Kit (Trilink Biotechnologies, USA) and sequenced on Illumina NextSeq500 instrument using NextSeq 500/550 Mid Output Kit v2.5 (150 cycles).

RNA-seq of triceps brachii muscles from mice after myostatin depletion and wheel running exercise

Project description:The purpose of this study was to determine whether postdevelopmental myostatin depletion influenced the changes in skeletal muscle gene expression profiles induced by a long-term increase in physical activity. Myostatin levels in muscles of adult male mice with floxed myostatin genes were reduced ~85% by activating Cre recombinase. Control mice with normal myostatin genes had the same Cre-activating treatment. Some of the mice were housed in ordinary cages throughout the study, limiting their physical activity. Other mice were given free access to running wheels for the final 12 weeks of the study. At the end of the study, comprehensive gene expression profiles of triceps brachii muscles were determined by RNA sequencing (RNA-Seq), with muscles from mice selected for similarity of running behavior throughout the period of wheel access. Wheel running increased expression of hundreds of mRNAs encoding proteins involved in oxidative energy metabolism, and this response was not affected by myostatin deficiency. The running-induced increase in the ratio of Myh1 mRNA (which encodes myosin heavy chain type 2x) to Myh4 mRNA (which encodes myosin heavy chain type 2b) also was not affected by myostatin depletion. At every threshold of P (computed by analysis of variance), the number of transcripts with interactions between activity level and myostatin level was fewer than the number expected by chance. These data suggest that myostatin is not required for transcriptional adaptations to moderate-intensity exercise. 12 samples, 6 from sedentary mice and 6 from active (wheel running) mice. 3 control and 3 myostatin-deficient mice within each activity level.

RNA-Seq analysis to study the transcriptomic profiles of mice after 4-month wheel running exercise

Project description:To identify the mechanism underlying AdipoR1-mediated beneficial effect of exercise, we used RNA-Seq analysis to study the transcriptomic profiles of mice after 4-month wheel running exercise. Differential expression analysis was performed by comparing exercised mice to control mice, and exercised mice subjected to AdipoR1 shRNA versus exercised mice.

Voluntary wheel running did not alter gene expression in 5xFAD mice, but in wild-type animals exclusively after one-day exercise bout

Project description:Physical activity is considered a promising preventive intervention to reduce the risk of developing Alzheimer’s disease (AD). However, the positive effect of exercise therapy has not been proven conclusively yet, likely due to confounding factors such as varying activity regimens and life or disease stages. To examine the impact of different exercise regimens in the early disease stages, we subjected young 5xFAD and wild-type mice to 1-day (acute, 3-month-old) and 30-day (chronic, 2-month-old) voluntary wheel running and compared them with age-matched sedentary controls. We observed a significant increase in brain lactate levels in acutely trained 5xFAD mice relative to all other experimental groups. Subsequent RNA-seq analysis from brain did not reveal major differences in transcriptomic regulation between training durations in 5xFAD mice. In contrast, acute training yielded large gene expression differences in wild-type animals relative to their chronically trained and sedentary counterparts. The comparison of 5xFAD and wild-type mice showed the highest transcriptional differences in the chronic and sedentary groups, whereas acute training was associated with much fewer DEGs. In conclusion, our results suggest that different training durations did not affect the global transcriptome of 3-month-old 5xFAD mice, whereas acute running seemed to induce a similar transcriptional stress state in wild-type animals as already known for 5xFAD mice.
