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.

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.

Project description:The goal of the endurance exercise training study in young adult rats was to perform exercise training studies in young adult (6-month-old) F344 rats, and from these rats collect multiple tissues in order to provide high quality samples for detailed analysis by chemical analysis sites. Tissues were collected from 10-12 rats sedentary control rats concurrent with the collection of the 8-week training groups. The 8-week training group and controls were from the same cohort and same age at euthanasia. For the older age group, an additional set of controls (n=5-6) were collected with the 1-2 week training group. Rats were either sedentary or underwent an exercise training program. Rats were exercised on the rodent treadmill 5 days per week using a progressive training protocol designed to exercise the rats at approximately 70% of VO2max and training was performed no earlier than 10:00 am and no later than 5:00 pm over 5 consecutive days per week. Training was initiated with the treadmill set at 70% of VO2 max and 5 degrees grade for 20 minutes. The duration of exercise was increased by one minute each day until day 31 of training (start of week 7), when a duration of 50 min was reached. Speed and grade of each training session increased in larger increments due to treadmill parameters. The highest intensity and duration of training began on day 31. This intensity was maintained for the final 10 days of the protocol to ensure steady state had been achieved. If any rats were unable to perform at least 4 days of training per week they were removed from the study and euthanized. It is important to note that the starting treadmill speed varied depending on the sex and age of the rat. The initial and maximum speeds were based on VO2max measurements obtained during the pre-training testing of the compliant rats. Rats assigned to the control group followed a schedule similar to the training group. They were placed in one lane on the treadmill for 15 minutes/day, 5 days per week. The treadmill was set at 0 m/min at an incline that corresponded to the incline being used by the training group.

Project description:We investigated the effects of diabetes, physical training, and their combination on the gene expression of cardiac muscle. Mice were divided to control (C), training (T), streptozotocin-induced diabetic (D), and diabetic training (DT) groups. Training groups performed 1, 3, or 5 weeks of endurance training on a motor-driven treadmill. Muscle samples from T and DT groups together with respective controls were collected 24 hours after the last training session. Gene expression of cardiac muscles were analyzed using Affymetrix Gene chip MG U74Av2 (Affymetrix , Inc., Santa Clara, CA). Experiment was performed on 10 to 15 weeks old male NMRI mice (Harlan, Holland) housed in standard conditions (temperature 22°C, humidity 60 ± 10 %, artificial light from 8.00 am to 8.00 pm, normally 5 animals per cage). Animals had free access to tap water and food pellets (R36, Labfor, Stockholm, Sweden). Animals were randomly divided into healthy and diabetic groups. The diabetic group received a single peritoneal injection of streptozotocin (STZ, Sigma-Aldrich, France, 180 mg/kg) dissolved in sodium citrate buffer solution (0.1 mol/l, pH 4.5) to induce experimental diabetes similar to type 1. The other group received injection of an equal volume of buffer. Diabetes was confirmed 72 hours after the injection by urine glucose testing (Glukotest(r), Roche, Germany), and mice were characterized diabetic when urine glucose values were greater than 200 mg/dl. Diabetic and healthy animals were randomly assigned into 12 groups (n = 5 per group), which were sedentary or trained for one, three or five weeks. Training groups performed 1 hour per day of treadmill running at 21 m/min and 2.5° incline. After one day of familiarization on a rodent treadmill, the mice ran as described above 5 days per week. Mice were sacrificed 24 hours after the last training bout (respective sedentary controls at the same time) by cervical dislocation followed by decapitation. Cardiac muscle was removed, weighed, snap frozen in liquid nitrogen and stored at -80°C for further analysis.

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).
