Mean, standard deviation, median interquartile range … 0000006365 00000 n A total of 30 male Sprague‑Dawley rats were randomly divided into three groups (n=10), including the control, OA and OA with treadmill exercise (OAE) groups. The mechanisms identified are likely to serve as substrates by which heart function declines and predisposes elderly people to heart failure. It has not been formally disseminated by the NTP. Blood was collected by decapitation from 3000 rats between 12.00 and 13.00. To address reports of TBP accumulation in human placenta and breast milk, studies were conducted to characterize TBP disposition and toxicokinetics in timed-pregnant or nursing Sprague Dawley (SD) rats following a single oral dose to the dam. The rats are maintained as an outbred closed colony. Thus, ASC transplantation post-burn scars shows the potential promising clinical benefits. Intact ventricular myocytes from MyBP-C(+/-) hearts displayed abnormal sarcomere shortening but unchanged Ca(2+) transient kinetics. Among the five cysteine residues of actin, Cys(239) and Cys(259) were oxidized to sulfenic (Cys-SOH), sulfinic (Cys-SO(2)H), or sulfonic (Cys-SO(3)H) acids by increasing amounts over the time periods studied. Statistical analysis was performed by Student’s T-Test (n=3; * p<0.05). %PDF-1.4 %���� Recent advances in basic science clarify several important mechanisms of aging. a role, as Sprague-Dawley (SD) and Wistar rats on a restricted diet havea lowerincidenceof PCM(Kemi et al.2000).SD rats have been widely used for toxicology studies (Keenan et al. rats nearly normalize. Shot- gun lipidomics approach displays unique changes in lipids biosynthesis in centenarians, with 41 differently abundant lipid species with respect to elderly subjects. 0000003205 00000 n 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. Hence, this study aimed to investigate the anti-obesity activity of Elateriospermum tapos (E. tapos) shell extract in obesity induced Sprague Dawley rats. Species: Rat. To Charles River in 1996. 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. 0000004719 00000 n The proposed model has been validated through an extensive literature analysis, which confirmed that 94% of the identified genes and miRs are related with cardiac senescence. Laboratory Animals, 24, 253-264 (1990). Microvolumes were used to analyse DNA samples. The ATF6, IRE1, BIP significantly decreased at 24- 72 hours.Conclusions: Our results indicate that regulation of the liver biogenesis is within a few hours after complete bile duct obstruction. Asian Journal of Biomedical and Pharmaceutical Sciences; 04 (37); 2014,33-37. International Journal of Molecular Sciences. 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. Sunitinib treatment decreased the expression of miR-27a in all age groups, while miR-133a and miR-133b levels were increased in 3 months and decreased in 24 months groups. National Toxicology Program . Biochemical analysis of the autophagic process. International Journal of Molecular Medicine. Specifically, the oxidative metabolism contributes to tissue homeostasis in triceps, whereas respiratory chain disruption and oxidative-stress-induced damage imbalance the homeostasis in gastrocnemius muscle. 0000026813 00000 n A standard pellet diet and water were given ad libitum. CB1 activation of Gi/o proteins inhibits the NAc shell and core via microdialysis in male Sprague-Dawley neurotransmission but the net inhibitory or excitatory effect of rats. TBP was well absorbed and metabolized to form glucuronide and sulfate conjugates after oral (0.1–1000 µmol/kg) and dermal (100 nmol/cm 2) administration with significant systemic bioavailability in Sprague Dawley (SD) rats and B6C3F1/Tac mice (Knudsen et al., 2019). These results reinforce the possibility that OPA1 might act as an inhibitor of mitochondrial fission . Alterations in articular cartilage and synovium were also evaluated by histology, immunohistochemistry, western blotting and reverse transcription‑quantitative polymerase chain reaction. At 24 hours and 1 week after treatment, ALDH2 activity was significantly higher in the α-LA group than in the untreated group (P < 0.05), whereas the levels of 8-iso-PGF2α were significantly lower in the α-LA group than in the untreated group (all P < 0.05). Male Sprague-Dawley rats, weighing - g, were purchased from Orient Bio Animal Laborato-ries,Kyunggi-do,Korea,andwereacclimatizedtostandard laboratory conditions ( ± C, ±% humidity and h light/dark cycle) for days. Its main advantage is its calmness and ease of handling. Haemodynamic alterations were observed following Sunitinib administration. clarify the relationships between ASCs, scar pain, apoptosis and autophagy. While in wild-type animals the number of proteins and the level of modification occurring during aging were comparable in the two analyzed muscles, Col6a1−/− mice displayed a number of muscle-type specific variations. – Uchino E., Tsuzuki, T. & Inoue, K. The effects of age and sex on seven elements in Sprague-Dawley rat organs. Rats were, Objective: We find that the biogenesis of mitochondria is response to the early stage of cholestasis with internal pathway. α-LA may ameliorate oxidative stress through up-regulating ALDH2 activity in patients with ACS.

The percentage of female rats with tumors was almost double that of males, which difference was accounted for chiefly … Int J Pharm 2015; 5(1):146-152 ISSN 2249-1848 the tail which helped to identify a particular animal. Fifteen rats were assigned to each of 12 groups. The studies discussed range from thrombosis and hemorrhage to vascular disease and transplant rejection and finally to sepsis and clinical studies in humans. In most developed countries, cardiovascular diseases are among the top causes of death and their development has been shown closely related to aging. Furthermore, autophagy is retained in triceps whereas an enhanced fusion, decrement of mitophagy and of regenerative potential is observed in aged gastrocnemius muscle. All rights reserved. We designed a study using a murine model involving the transplantation of autologous ASCs in rats subjected to burn injuries. In adult Col6a1−/− mice, the major variations were found in the enzymes belonging to the glycolytic pathway and the tricarboxylic acid (TCA) cycle, as well as in autophagy-related proteins. In order to provide historical and reference data for the research community, several of these articles are noted below. The .gov means it's official. A total of 30 male Sprague‑Dawley rats were randomly divided into three groups (n=10), including the control, OA and OA with treadmill exercise (OAE) groups. However, most studies have been focused on skeletal muscle features. The relative contents of hydroxy-tryptophan, N-formyl-kynurenine, and kynurenine increased after irradiation, reaching a maximum in the 9 h sample. Sepsis in Sprague-Dawley Rats. This profile is more pronounced in hindlimb than in forelimb muscles, both in humans and in rodents. 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. These findings reveal phospho/sphingolipids as putative markers and biological modulators of healthy aging, in humans. Skinned myocardium isolated from MyBP-C(+/-) hearts displayed decreased cross-bridge stiffness at half-maximal Ca(2+)-activations, increased steady-state force generation, and accelerated rates of cross-bridge recruitment at low Ca(2+)-activations (<15% and <25% of maximum, respectively). A) Histograms of differential protein expression in cardiac tissue of old adult (22 months, gray bars) and senescent (30 months, black bars) rats, as detected by 2-D DIGE analysis. GSM-RFR 1.8GHz Sex No. ... On the other hand, and as previously mentioned, mitophagy is promoted by fission . All rights reserved. Interleukin (IL)‑1β and IL‑4 levels in the serum and intra‑articular lavage fluid (IALF) were measured by ELISA. Collectively, our data show that reduced MyBP-C expression and phosphorylation in the sarcomere results in myofilament dysfunction, contributing to contractile dysfunction that precedes compensatory adaptations in Ca(2+-)handling, and chamber remodeling. Sprague-Dawley, Inc. Harlan became Envigo in 2015. This study highlights the importance and impact of ageing and anti-cancer therapy-induced cardiotoxicity. When 4-phenylbutyric acid and chloroquine were combinedly administrated in spinal cord injury rats, chloroquine abolished the blood-spinal cord barrier protective effect of 4-phenylbutyric acid by exacerbating ER stress after spinal cord injury, indicating that the cross-talking between autophagy and ER stress may play a central role on blood-spinal cord barrier integrity in acute spinal cord injury. evaluated upon completing the treadmill exercise program (speed, 18 m/min; 30 min/day; 5 days/week for 4 weeks). 0000025125 00000 n Reproductive Toxicology Statistical analysis was performed by Student’s T-Test (n = 3; * p<0.05). Patients in the α-LA group were given an intravenous injection of 600 mg α-LA every day for 5 days while the patients in the untreated group were given saline. This study aimed to validate an analytical method to determine DNA concentration using standard reference material (NIST SRM 2372) and Sprague Dawley rat and human DNA.

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. 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. Regardless of the health . Infarct size was increased in all Sunitinib treated age groups. Among the four tryptophan residues present in actin, only Trp(79) and Trp(86) appeared to undergo oxidation. 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 this review, we discuss mammalian and viral serpins as regulators of coagulation and inflammation. The percentage of female rats with tumors was almost double that of males, which difference was accounted for chiefly by the high incidence of mammary tumors in the females. 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. Thus, exercise could have effects on the major cell signaling pathways that are involved in the mitochondria quality and quantity control in the elderly. 0000021021 00000 n Albino rats (Rattusnorvegicus; Sprague-Dawley The experiment animals were marked carefully on www.pharmascholars.com 147 Rakib Hasan, et al. 0000001646 00000 n The wild-type Sprague Dawley rat thymus was comprised mostly of CD4/CD8 double positive cells whereas in the SRG rat, the viable cells recovered were CD4-/CD8- (Fig 1A–1C). Hematological studies of Sprague Dawley rats with dextrocardia. Overall, 20 male and 20 female SD rats were fed by pellets made by GM rice in 50% of needed carbohydrate for 90 days. B) Immunoblotting of selected proteins (identified by proteomic analysis) in young, old adult and senescent rat cardiac muscles. They were acclimatized under controlled temperature with a 12-h light/12-h dark cycle for a period of one week. Data were normalized against the total amount of loaded proteins stained with Sypro Ruby. Why are you such a great model? 0000002036 00000 n MKK7 mRNA level was increased in 24 months group and p-MKK7 levels were increased in 12 months group following Sunitinib treatment. Cancer Chemotherapy and Pharmacology 2017, 80 (2) , 317-332. Skin tissues and dorsal horn of lumbar spinal cords were removed for biochemical analysis.

PDF | Obesity is one of the risk factors associated with cardiovascular diseases, hypertension, abnormal liver function, diabetes, and cancers. Moreover, reduced mitochondrial function can contribute to age-associated disease phenotypes in model organisms and humans. Calm demeanor Easy to handle in the lab The results of western blotting demonstrated that LC3II was notably decreased in the OA group and partially increased in the OAE group. MYH6 myosin-6 has been demonstrated ectopically regulated in senescent rats against young rats, ... MYH6: myosin-6 has been demonstrated ectopically regulated in senescent rats against young rats, Define the physiopatological mechanisms of muscle loss and counteract them, Background: MKK7 mRNA and p-MKK7 levels were decreased in the 3 months group after Sunitinib treatment. Sepsis in Sprague-Dawley Rats. These results support the hypothesis of successful aging in this rat model. Biochemical analysis of mitochondrial plasticity. Macroscopic observation of organs in situ in Sprague Dawley rats. strain of Charles River Sprague Dawley rats has prolactin-induced pituitary stimulation, and therefore, the window of susceptibility for mammary tumorigenesis is absent. Conclusion: The rats were refreshed with NIH Genetic Resource stock in 1998. In particular, gastrocnemius displayed a limited number of dysregulated proteins in adult mice, while in aged muscles the modifications were more pronounced in terms of number and level. and consistency, turn to the Sprague . Despite a lack of left ventricular hypertrophy, MyBP-C(+/-) hearts exhibited elevated end-diastolic pressure and decreased dP/dtmax, which was normalized following dobutamine infusion. Anti-cancer drug Sunitinib is linked to adverse cardiovascular events, which have shown to involve mitogen activated kinase kinase 7 (MKK7) pathway. Cardiac function and infarct size were measured during/after 125 min of Sunitinib treatment. Serpin-mediated regulation of the thrombotic pathway is then discussed, with emphasis on those serpins that have been evaluated as potential new drugs. Although it is known that several exercise protocols are able to modify the activity and turnover of mitochondria, further studies are necessary in order to better identify the mechanisms of interaction between mitochondrial functions, aging and physical activity, as well as to analyze possible factors influencing these processes. The adult body weight is 250–300g for females, and 450–520g for males. Statistical analysis was performed by Student’s T-Test (n=3; * p<0.05). Interestingly, in triceps, both molecules are increased in the nucleus in aged rats and are associated to an increased protein acetylation and myoglobin availability. In this study, we have investigated the effects of ROS on actin in an established rat model of acute oxidative stress using short-term X-ray irradiation. Alpha-lipoic acid (α-LA), a natural dithiol compound with antioxidant properties, has been reported to increase ALDH2 activity in cultured cells. An isoprostane, 8-iso-prostaglandin F2α (8-iso-PGF2α), one product of arachidonic acid metabolism, was measured as a marker for oxidative stress. 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. Wistar rats are more active than others like Sprague Dawley rats. Perturbations in mechanical and electrical activity in MyBP-C(+/-) mice could increase their susceptibility to cardiac dysfunction and arrhythmia. However, the mechanism by which heart function declines and heart failure increases in association with age is not clear. ��%�| 9�7;�E10�� ,xr[�R���K�L�ʡ����Dc ������2�4#�0 �� endstream endobj 15 0 obj <>>> endobj 16 0 obj <>/Font<>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/Rotate 0/TrimBox[0.0 0.0 595.276 841.89]/Type/Page>> endobj 17 0 obj <> endobj 18 0 obj <> endobj 19 0 obj <> endobj 20 0 obj <> endobj 21 0 obj <> endobj 22 0 obj <> endobj 23 0 obj <> endobj 24 0 obj <>stream The average litter size of the Sprague Dawley rat is 10.5. Collagen VI is an extracellular matrix (ECM) protein playing a key role in skeletal muscles and whose deficiency leads to connective tissue diseases in humans and in animal models. 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. The Sprague Dawley® outbred model was developed by Sprague Dawley, Inc. NIH received stock from Sprague Dawley, Inc in 1945. H�\�͎�@��. Data were normalized against the total amount of loaded proteins stained with Sypro Ruby. Sprague-Dawley, Inc. Harlan became Envigo in 2015. Coat Color Loci: Tyr c. Color: Albino. Federal government websites often end in .gov or .mil. ER stress inhibitor, 4-phenylbutyric acid, and autophagy inhibitor, chloroquine, were respectively or combinedly administrated in the model of acute spinal cord injury rats. Met(82) was also further oxidized to the sulfone. In this study we investigated the impact of mitochondrial metabolism and biology as determinants of successful aging in primary cultures of fibroblasts isolated from the skin of long living individuals (LLI) (about 100 years old) compared with those from young (about 27 years old) and old (about 75 years old) subjects. 0000000896 00000 n U.S. Department of Health and Human Services . 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.

At 24 h, the activities had partially recovered to 64 and 80% of the control sample, respectively. Group Treatment Animals No. 0000001221 00000 n Sprague–Dawley rat pups of postnatal day (P) 10 or 20 were subjected to generalized and sustained convulsions (>20 min duration, a model for status epilepticus, SE), provoked by i.p. The objective of this experiment was to determine whether changes in liver cholesterol content, plasma lipids and lipoprotein composition result from dietary manganese (Mn) deficiency in the Sprague-Dawley (SD) and the Wistar (W) rat. As centenarians well represent the model of healthy aging, there are many important implications in revealing the underlying molecular mechanisms behind such successful aging. Utilizing light and electron microscopy, myosin heavy chain isoform distribution, proteomic analysis by 2D-DIGE, MALDI-ToF MS and quantitative immunoblotting, this study analyzed the protein levels and the nuclear localization of specific molecules, which can contribute to a preferential muscle loss. We analyzed the therapeutic efficacy of α-LA in 63 patients with confirmed acute coronary syndrome (ACS). Early murine cholestatic liver injury is via autophagy pathway. Furthermore, electrocardiogram recordings in conscious MyBP-C(+/-) mice revealed prolonged QRS and QT intervals, which are known risk factors for cardiac arrhythmia. Key words: DMBA, mammary carcinogenesis, Charles River Sprague Dawley rats 1. 0000007736 00000 n Then, sampling was done from rats liver. 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. The serum levels of 8-iso-PGF2α and ALDH2 activity were determined at admission to the hospital (time 0), and at 24 hours and 1 week after treatment. To examine whether this observation may be species specific or more generalisable, the effect of this diet in rats was examined. Sprague . National Toxicology Program . B) Validation of Hspa8 protein by immunoblotting in young, old adult and senescent rat cardiac muscles. 0000003429 00000 n 0000005523 00000 n induced (HFD) of adolescent rats. pharmaceuticals in Sprague-Dawley rats Nam Hee Youn1, Eun Ji Kim1, Jung-Sun Yi1, Joo Hwan Kim1, Ye-Jin Cho2, Ki Taek Nam2, Ki Sook Park1 and Jong Kwon Lee1* Abstract Some drugs cause phototoxicity in humans when exposed to light, thus there is a need for an in vivo phototoxicity test to evaluate them. We focus first on the thrombotic and thrombolytic serine proteases and known interactions between these protease cascades and elements of the innate immune response. Our research goal was to calculate a dose of DMBA at each age in which 50% of the rats developed carcinoma in situ (CIS) within three months (IC50) in this strain of Sprague Dawley female rats. and prepared for stereotaxic infusion of drug (0–10 nmol ferrous citrate and/or 0–16.8 nmol GSNO in 1 μl sterilized Ringer's solution or 0–33.6 nmol peroxynitrite in 1.05 μl 0.3 M NaOH solution) into right or left substantia nigra compacta area (i.n. Sprague Dawley rats in health. The Hsd:Sprague Dawley ® SD rat has a wide array of historical research use including in the field of cardiology. Conversely, an increase of fusion, a decrease of mitochondrial fission and the activation of the non-canonical autophagy pathway were observed. The levels of MyBP-C phosphorylation were reduced 53% in MyBP-C(+/-) hearts compared to wild-type hearts. 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. 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.
