Forced intensity-controlled endurance training on a small-animal treadmill machine inducing murine cardiac hypertrophy

ABSTRACT: Endurance training is associated with decreased cardiovascular-related morbidity and mortality. Cardiac hypertrophy is an adaptive mechanism of the heart in response to volume and pressure overload. Nonetheless, murine exercise models for cardiac hypertrophy are still under discussion. Using a small-animal treadmill, a forced intensity controlled training model was conducted to characterize cardiac hypertrophy in mice utilizing multimodal analyses. Wild-type male C57BL/6 mice age between 5-8 weeks old were subjected to 8 weeks of forced endurance training using a small-animal treadmill or sedentary age-matched control. Transcriptomic analysis of 8-week training hearts was evaluated using RNA sequencing. RNA sequencing revealed several genes involved in the cell cycle, apoptosis, contractile protein expression, and organ growth that were among the most differentially regulated genes after 8-weeks of exercise.

Transcription profiling of heart tissue from rats that have undergone treadmill exercise or have been sedentary for different lengths of time

Project description:Seventy two rats were randomized to twelve independent groups of rats (n = 6 in all groups) where half of the rats were chosen for training (treadmill exercise training 1.5 hour 5 days a week, in 1, 4, 24, 48 days and for 4 and 8 weeks) or sedentary (no training) as described in detail by Wisloff et al. (Intensity-controlled treadmill running in rats: VO(2 max) and cardiac hypertrophy. Am J Physiol Heart Circ Physiol. 2001 Mar;280(3):H1301-10.) or Kemi et al.(Aerobic fitness is associated with cardiomyocyte contractile capacity and endothelial function in exercise training and detraining. Circulation. 2004 Jun 15;109(23):2897-904. Epub 2004 Jun 1.). The rats were scarified one hour after training (1, 4, 24 and 48 days) or 24 hours after training (4 and 8 weeks). Biopsies form left ventricle was taken form all rats and stored on -80°C for preparation of RNA. The same procedures were performed for the control/sedentary rats which were sacrificed at the same time as the exercised rats.

Transcription profiling of rat heart left ventricle after exercise to investigate the role of exercise as a known protective factor against cardiovascular morbidity and mortality

Project description:Physical exercise training is a known protective factor against cardiovascular morbidity and mortality. Nevertheless, the underlying specific molecular mechanisms still remain uncompletely explored. To identify molecular mechanisms by which exercise training induces this favorable phenotype a genomic approach was used in an animal model of mild exercise previously demonstrated by our group to induce cardioprotection. Our data indicate that mild exercise by inducing no or few permanent changes in gene expression profile is able to determine cardioprotection without induction of cardiac hypertrophy. Experiment Overall Design: We investigated the gene expression profile by Affymetrix technology (230 2.0 GeneChip rat genome array) induced by mild exercise training (treadmill running: 25 m/min, 10% incline, 1 h/day, 3 days/week, 10 weeks) on left ventricle (LV) of exercise-trained (n=10) and sedentary control (n=10) rats.

Endurance training in early life results in long-term programming of heart mass in rats

Project description:This study aimed to examine if early life exercise could normalize the reduced heart mass we have previously observed in the adult hearts from growth restricted rats. We investigated the molecular pathways using microarray analysis to explain how endurance exercise in early life might be regulating the sustained increase in heart mass we have observed in these rats in adulthood. At 5 weeks of age, male WKY rats were allocated to one of the following exercise treatments: remained sedentary with post mortem (PM) at 9 or 24 weeks, early exercise training (from 5-9 weeks of age) with PM at 9 or 24 weeks, or later exercise training (from 20-24 weeks of age) with PM at 24 weeks (n=8 males/group). Exercise training involved treadmill running 5 days/ week for 4 weeks. Running duration progressively increased from 20 up to 60 minutes per day, with the treadmill speed set at 15 m/min for the first week and 20 m/min thereafter. At 9 or 24 weeks of age rats were killed with an intraperitoneal injection of Ilium Xylazil-20 (30 mg/kg) and Ketamine (225 mg/kg). The rats in the 9 week old early exercise and 24 week old later exercise groups were killed 72 hours following the last bout of treadmill running. Total RNA was obtained from the whole-hearts for analysis Total RNA obtained from the hearts of WKY rats. Male offspring remained sedentary or underwent treadmill running from 5-9 weeks (early exercise) or 20-24 weeks of age (later exercise).

MoTrPAC: Endurance Exercise Training Study In 6 Months Old Rats

Project description:MoTrPAC endurance exercise training study targets young adult (6-month-old) rats. Specifically, male and female Fischer 344 rats (n = 12) were subjected to progressive treadmill endurance exercise training for 1, 2, 4, or 8 weeks, with tissues collected 48 hours after the last exercise bout. Sex-matched sedentary, untrained rats were used as controls. This study contributes to MoTrPAC's broader mission, which is to identify molecular changes occurring due to exercise. The ultimate goal is to understand how physical activity can improve and sustain health across various ages and fitness levels. The program is supported by the NIH Common Fund.

RNA-Seq of the pituitary gland of mice after 3-week treadmill training versus sedentary control

Project description:This study investigates the effects of exercise and genetic predisposition on the transcriptomic profile of the pituitary gland of long-term selected marathon (DUhTP) and non-inbred (DUC) mice. In the exercise group, mice underwent treadmill training for three weeks. For the sedentary control group, mice were kept under minimal physical activities. For the 3-week training program, the mice were running five days per week (Monday to Friday) starting at age of 49 days after birth (Walz et. al. 2021). All mice used in this experiment were male and sacrificed at day 70 of life for tissue sampling.
