A spontaneous tumor incidence of 45% was noted in 360 Sprague-Dawley rats (179 males and 181 females) and a 26% incidence was seen in 254 Swiss mice (101 males and 153 females) used as untreated control animals in an 18-month series of carcinogenesis experiments. In the skeletal muscle, the ageing process is characterized by a loss of muscle mass and strength, coupled with a decline of mitochondrial function and a decrease of satellite cells. Reduction in function of extra-cardiac organs is likely to be another important mechanism by which heart failure increases with aging, since heart failure is a multiple organ system disease. The underlying oxidative modifications were also studied at the molecular level. Haemodynamic alterations were observed following Sunitinib administration. However, a direct comparison between Wistar and Sprague-Dawley (SD) Rat as models of high-fat (HF) diet-induced obesity has not been adequately evaluated so far. B) Immunoblotting of selected proteins (identified by proteomic analysis) in young, old adult and senescent rat cardiac muscles. 0000011478 00000 n in male and female F344 and Crl:CD (Sprague-Dawley [SD]) rats are rare. Microvolumes were used to analyse DNA samples. On the contrary, inhibition of autophagy by treating with chloroquine exacerbated blood-spinal cord barrier permeability, promoted the loss of TJ proteins and enhanced ER stress after spinal cord injury. sativus ethanolic extract as a hypoglycemic agent on Sprague-Dawley rats randomly divided into five groups of five induced to diabetes using alloxan (120 mg/kg body weight intraperitoneal). Then, sampling was done from rats liver. The rats are maintained as an outbred closed colony. Sprague-Dawley rats (male 250–350 g, Taconic Farms) are anesthetized with chloral hydrate (400 mg/kg, i.p.) The rats of both sexes, weighing 151±29, were housed in cages, individually and in colony, for the diabetic and non-diabetic group respectively. Anti-cancer drug Sunitinib is linked to adverse cardiovascular events, which have shown to involve mitogen activated kinase kinase 7 (MKK7) pathway. Alpha-lipoic acid (α-LA), a natural dithiol compound with antioxidant properties, has been reported to increase ALDH2 activity in cultured cells. Macroscopic observation of organs in situ in Sprague Dawley rats. Thus, exercise could have effects on the major cell signaling pathways that are involved in the mitochondria quality and quantity control in the elderly. In rat hearts, 6 stress response and 4 other proteins were identified: Gstp1, glutathione S-transferase P; Hspa8, heat shock cognate 71kDa protein; Mpst, 3-mercaptopyruvate sulfurtransferase; Pdia3, protein disulfide-isomerase A3; Prdx2, peroxiredoxin-2; Rnh1, ribonuclease inhibitor; Anxa5, annexin A5; Serpina1, alpha-1-antiproteinase (2 proteoforms); Serpina3k, serine protease inhibitor A3K; Serpina3l, serine protease inhibitor A3L. Sprague-Dawley rats, from prenatal life to spontaneous death: plan of the experiment (Experiment BT 1CEMRF). Serpin-mediated regulation of the thrombotic pathway is then discussed, with emphasis on those serpins that have been evaluated as potential new drugs. Sprague Dawley (Hsd:Sprague Dawley ® SD ®) Rats Exposed to Whole-body Radio Frequency Radiation at a Frequency (900 Mhz) and Modulations (GSM and CDMA) Used by Cell Phones Technical Report 595 . A similar metabolic rewiring and autophagic impairment was found in the diaphragm of 24-month-old wild-type mice, confirming that fatty acid synthase (FASN) increment and decreased microtubule-associated proteins 1A/1B light chain 3B (LC3B) lipidation are hallmarks of the aging process. 0000005054 00000 n The aim was to detect the anti-neuroinflammation effect of ASC transplantation and, Increased levels of reactive oxygen species (ROS) cause oxidative stress and are believed to play a key role in the development of age-related diseases and mammalian aging in general by oxidizing proteins, lipids, and DNA. Conversely, an increase of fusion, a decrease of mitochondrial fission and the activation of the non-canonical autophagy pathway were observed. The rats’ obesity was induced by a high-fat (HF) diet made up of 50% standard rat pellet, 20% milk powder, 6% corn starch, and 24% ghee and a cafeteria (CAF) diet such as chicken rolls, salty biscuits, cakes, and cheese snacks.

Impairment in Male Sprague-Dawley Rats BinSong, 1,2,3 FengjuanWang, 4 andWeiWang 1,2,3 Department of Human Anatomy and Histoembryology, School of Basic Medical Sciences, Fujian Medical University, I am a model organism used by Duke University to research the impacts of chemical exposure on behavior, memory, and cognitive ability. The pure computationally inferred model presented in the paper is therefore a good candidate to represent the relationship between key genes and miRs involved in cardiac senescence processes, and represents a reliable selection of genes and miRs for further studies, in order to elucidate and better detail their involvement in cardiac aging. In 1991, 8 colonies were selected to form the IGS Foundation Colony using the Charles River International Genetic Standard System. Thus, ASC transplantation post-burn scars shows the potential promising clinical benefits. Blood, 56 (5) (1980). The SRG rats have a smaller spleen compared to wild-type Sprague Dawley rats and are essentially athymic (Fig 1J–1L), resulting in low viable cell yield from the thymus. Sprague Dawley Inc. Laboratory Animals, 24, 253-264 (1990). For proteins having proteoforms with opposite trends in the same group, the global protein expression is reported in frames. Proteoform: A single term describing protein complexity, Sirtuin-3 deacetylation of cyclophilin D induces dissociation of hexokinase II from the mitochondria, Development of a strain spontaneously hypertensive rats, Specific protein changes contribute to the differential muscle mass loss during ageing, The Serpin Solution; Targeting Thrombotic and Thrombolytic Serine Proteases in Inflammation, Alpha-Lipoic Acid Ameliorates Oxidative Stress by Increasing Aldehyde Dehydrogenase-2 Activity in Patients with Acute Coronary Syndrome, Hexosamine Biosynthetic Pathway as target for cancer therapy, Autologous Adipose-Derived Stem Cells Reduce Burn-Induced Neuropathic Pain in a Rat Model. a sort of mitochondrial "hypertrophy". These patients (52 men and 11 women, with age range 49-72 years) were randomized into two groups: untreated group (n = 30) and α-LA group (n = 33). 0000026813 00000 n Try out the SAS Sprague Dawley rat with our animal model evaluation program→ ASC transplantation significantly restored the mechanical threshold reduced by burn injury. Reproductive Toxicology The analytes were stable on the bench‐top (8 h), after three freeze–thaw cycles, in the autosampler (8 h) and as a dry extract (−80°C for 48 h). TBP is detected in environmental matrices and biota, including human breast milk, placenta, and serum. Of the 1,928 control male and 1,928 control female F344 rats, there were no cholangiocarcinomas and only one female with a cholangioma (Haseman et al. However, the expression of type II collagen in the articular cartilage increased in the OAE group as compared with the OA group, whereas ADAMTS5 expression decreased. To examine whether this observation may be species specific or more generalisable, the effect of this diet in rats was examined. Upper panel: Histograms of protein expression normalized to the total protein stain (mean±SD). 0000003205 00000 n 0000005439 00000 n Furthermore, electrocardiogram recordings in conscious MyBP-C(+/-) mice revealed prolonged QRS and QT intervals, which are known risk factors for cardiac arrhythmia. In conclusion, 30 min of treadmill exercise had an evident protective effect in the articular cartilage of rats with MIA‑induced OA and may promote autophagy in the articular cartilage. 0000003318 00000 n In order to provide historical and reference data for the research community, several of these articles are noted below. Finally the potential of viral serpins that target the coagulation and thrombolytic cascades as potential therapeutics for anti-inflammatory properties is discussed from basic molecular activity to studies in animal models. One such mechanism is insulin/insulin-like growth factor (IGF)-1 signaling. Sunitinib-induced cardiotoxicity in 3, 12 and 24 months old male Sprague-Dawley rats and MKK7 expression and activation was investigated using the Langendorff perfused heart model followed by Western blot analysis. AT 900 MHz IN Hsd:SPRAGUE DAWLEY SD RATS (WHOLE-BODY EXPOSURE) Scheduled Peer Review Date: March 26 to 28, 2018 NOTICE This DRAFT Technical Report is distributed solely for the purpose of predissemination peer review under the applicable information quality guidelines. I am a Sprague Dawley rat. A standard pellet diet and water were given ad libitum. Skin tissues and dorsal horn of lumbar spinal cords were removed for biochemical analysis. Laboratory Animals, 24, 253-264 (1990). In the present study, we respectively detected the roles of ER stress and. Sprague-Dawley rats were purchased from BioPhilippines, Manila. 0000002036 00000 n Aging is a universal phenomenon involving the whole body and is characterized by metabolic and physiological decline, leading to cardiovascular defects and heart failure. These processes are essential for the maintenance of mitochondrial structural integrity and, therefore, for cell life, since mitochondrial dysfunction leads to an impairment of energy metabolism and increased production of reactive oxygen species, which consequently trigger mechanisms of cellular senescence and apoptotic cell death. Recent advances in basic science clarify several important mechanisms of aging. The rats are maintained as an outbred closed colony. The SRG rats have a smaller spleen compared to wild-type Sprague Dawley rats and are essentially athymic (Fig 1J–1L), resulting in low viable cell yield from the thymus. demonstrated that elements of heart protection could be present in disease-free ageing of Sprague-Dawely rats. Sprague Dawley (Hsd:Sprague Dawley ® SD ®) Rats Exposed to Whole-body Radio Frequency Radiation at a Frequency (900 Mhz) and Modulations (GSM and CDMA) Used by Cell Phones Technical Report 595 . Animal models are very valuable tools to decipher at the molecular level changes occurring during muscle aging, sarcopenia and muscle disorders. Sprague–Dawley rats were randomly assigned to two diet groups, group A and B (n= 18 per group): Experimental pre-diabetes was induced in male Sprague–Dawley rats using a protocol previously described by Luvuno et al. 0000003429 00000 n In order to carry out comparative studies between animal models and humans, a precise phenotypic characterization should be performed, accounting for both muscle development and metabolism (Capitanio et al., 2005(Capitanio et al., , 2009, ... Ectopic secretion of lysosomal proteases can, in fact, degradate extracellular matrix, contributing to atherosclerosis, arthritis, aneurysms formation, and other diseases [63]. Comparison of the proteomic features and the molecular analysis of metabolic and autophagic pathways in adult and aged Col6a1−/− diaphragm indicated that the effects of aging, culminating in lipotoxicity and autophagic impairment, were already present at 6 months of age. We designed a study using a murine model involving the transplantation of autologous ASCs in rats subjected to burn injuries. To elucidate the effects of decreased MyBP-C expression on cardiac function, we employed MyBP-C heterozygous null (MyBP-C(+/-)) mice presenting similar decreases in MyBP-C expression (32%) as FHC patients carrying MyBP-C mutations. In order to provide historical and reference data for the research community, several of these articles are outlined below. © 2008-2021 ResearchGate GmbH. An isoprostane, 8-iso-prostaglandin F2α (8-iso-PGF2α), one product of arachidonic acid metabolism, was measured as a marker for oxidative stress. November 2018 . I am a model organism used by Duke University to research the impacts of chemical exposure on behavior, memory, and cognitive ability. Proteins significantly altered (ANOVA and Tukey, p<0.01) are expressed as a ratio of spot volume variations in old adult and senescent rats versus young (6 months) control, respectively.
