The high incidence of breast cancer cases in the world requires the use of applicative methods. The 7,12-dimethylbenz(a)anthracene (DMBA) induced breast cancer animal model is a widely used chemical-induced animal models for research on breast cancer. However, the molecular mechanism related to DMBA induction remains unclear. Good understanding on DMBA-induced animal models is crucial for studies related to future breast cancer treatments as animal models will provide a deeper understanding of anticancer medication, specifically those aimed for treating breast cancer. The aim of this study was to develop an DMBA-induced animal model for breast cancer. This study used female Wistar rats injected subcutaneously with DMBA as a carcinogen-induced agent (20 mg/kg) to induce tumor. Rat tumors were then evaluated and breast appearance was observed weekly, starting from day 28th after DMBA injection. Breast cancer tissue was then sampled and stored at -80°C until it was used for western blot and histological study. This study indicated that DMBA induced cancer in female Wistar rat’s breasts, and cytoplastic cells and lung metastatic was identified macroscopically and histopathologically. The metabolic sign was observed in the lung and breast sections. Interestingly, the DMBA induction in this study does not only induce organ cancers but also induces estrogen receptors and stimulates signaling of estrogen receptors α (ERα), ERβ, and Akt.

Gut microbiome profile is related to individual health. In metabolic syndrome, there is a change in the gut microbiome profile, indicated by an increase in the ratio of Firmicutes to Bacteroidetes. Many studies have been conducted to determine the effect of exercise on modifying the gut microbiome profile. The effectiveness of exercise is influenced by its type, intensity, and duration. Aerobic training decreases splanchnic blood flow and shortens intestinal transit time. High-intensity exercise improves mitochondrial function and increases the essential bacteria in lactate metabolism and urease production. Meanwhile, exercise duration affects the hypothalamic-pituitary-adrenal axis. All of these mechanisms are related to each other in producing the effect of exercise on the gut microbiome profile.

Reactive oxygen species (ROS) are oxygen derivatives that arise intrinsically from the oxidative phosphorylation process and extrinsically as a response to xenobiotics and pollution. ROS is involved in various conditions such as exercise, aging, inflammation, and neurodegenerative diseases. In the aging process, increased cellular senescence and decreased endogenous antioxidants also occur. Meanwhile, physical activity, specifically exercise, can modulate ROS. The impact of exercise on ROS varies from harmful to beneficial and depends on the type of exercise as they induce different types of ROS. Long-term exercise regulates signaling pathways that enhance antioxidant defense systems and control ROS production. This review will discuss studies on how exercise can regulate ROS and which type of exercise has a role in delaying the aging process. This review also exposes the impact of nutraceutical antioxidant agents that likely enhance the benefit of exercise. The nutraceutical antioxidants agents that likely enhance the benefit of exercise are creatine, whey, and ascorbic acid. Exercise is rewarding for the aging population concerning increasing their quality of life. Special consideration to exercise needs to be given to the type of exercise, and the exercise must be done continuously.

Abstract: Adaptation of cardiac muscle to regular exercise results in morphological and structural changes known as physiological cardiac hypertrophy, to which the Hippo signaling pathway might have contributed. Two major terminal effectors in the Hippo signaling pathway are Yes-associated protein (YAP) and its homolog transcriptional coactivator with PDZ-binding motif (TAZ). The latest studies have reported the role of YAP and TAZ in different life stages, such as in fetal, neonatal, and adult hearts. Their regulation might involve several mechanisms and effectors. One of the possible coregulators is exercise. Exercise plays a role in cardiomyocyte hypertrophic changes during different stages of life, including in aged hearts. YAP/TAZ signaling pathway has a role in physiological cardiac hypertrophy induced by exercise and is associated with cardiac remodelling. Thus, it can be believed that exercise has roles in activating the signaling pathway of YAP and TAZ in aged cardiomyocytes. However, the studies regarding the roles of YAP and TAZ during cardiomyocyte aging are limited. The primary purpose of this review is to explore the response of cardiovascular aging to exercise via signaling pathway of YAP and TAZ.

The prevention of liver disease could be conducted through preventive strategies, such as antioxidants and exercise. Moringa leaf extract has substances that could act as antioxidant, while exercise is also known protecting the liver from disease by changing hepatic metabolism and autophagy. This study aimed to investigate the effect of moringa leaf extract and moderate intensity exercise on histopathological appearance and autophagy gene expression of wistar rat liver. The method used in this study was animal experiment using 24 male wistar rats divided into 4 groups, including control group, moringa group, exercise group, and moringa + exercise group. Moringa leaf extract was given in low dose (5.7 mg/kgW) per oral, 5 times a week, for 4 weeks. Meanwhile, the 20 m/minute treadmill exercise was given for 30 minutes per day, 5 times a week, for 4 weeks. Results showed a significant change on histopathological scoring in exercise group (p=0.011) compared to control group. Increased autophagy gene expression was found in moringa + exercise group compared to control group (LC3 0.90 fold; p62 0.87 fold). In summary, this study presented that moderate intensity exercise induced changes on histopathological appearance of wistar rat liver that might be associated with physiological inflammation. Moringa, with its antioxidant properties, combined with increased autophagy might improve histopathological changes in moringa + exercise group.

BACKGROUND: Recently, coffee is widely used for preventing photoaging because of its antioxidant capacity. Among two kinds of coffee, robusta coffee has higher content of antioxidant such as chlorogenic acid (CGA) and caffeine. Researchs about robusta coffee bean effect on photoaging due to UVB radiation is still limited. Therefore, the aim of this study was to examine the effect of robusta extract cream (RE cream) on preventing wrinkle in mice induced by ultraviolet-B (UVB) radiation. METHODS: RE cream was made by mixing RE coffee with moisturizing cream in different concentration (10%, 20%, and 40%). Twenty-five male of Mus musculus Balb/c strain mice aged 4 weeks were divided into five groups; control group, UVB group, UVB + 10% RE group, UVB + 20% RE group, and UVB + 40% RE group. The UVB groups were given UVB radiation three times a week with an exposure duration of 100 seconds per time for ten weeks. At the end of the treatment, skin samples were excised and statined histologically, also were analyzed for their protein expression. Evaluation of wrinkles was carried out using the Bissete method before and after treatment. To evaluate the thickness of the epidermis, HE staining was performed, while masson Trichome staining was performed to determine the collagen content. RESULTS: RE cream-treated groups showed lower wrinkle score compared to the control group. Furthermore, in UVB + 10% RE group, the RE cream application reduce wrinkle formation. In UVB + 10% RE group and UVB + 20% RE group, the RE cream application increased epidermal thickness and collagen content ( p =0.00). While collagenase, matrix metalloproteinase-1 (MMP-1) expression was lower in UVB + 20% RE group compared to the UVB group ( p

Puerperal breast inflammation is common in the first 6-8 weeks postpartum, and without proper management, may lead to a decrease in breastmilk production and early cessation of breastfeeding. Recent studies showed that carotenoids decrease the severity of puerperal breast inflammation. This article summarizes the significant findings on β-carotene with a potential role as an autophagy modulator in puerperal breast inflammation. Puerperal milk stasis causes an increase in inflammatory cytokines and inflammatory cells, leading to reactive oxygen species (ROS) activation that causes oxidative damage to mammary glands and affects breast milk secretion. β-carotene has an anti-inflammatory effect related to its ROS-scavenging activity and modulates autophagy, thus stimulating the removal of damaged cellular structures and supporting milk gland survival. β-carotene modulates autophagy through phosphorylation of NF-κB, JNK, p38, Akt, and Nrf2, affects the ratio of Microtubule-associated protein 1A/1B-light chain 3 (LC3)-II/LC3-I, and has a role in the regulation of the JAK2/STAT3, PI2K/Akt/mTOR and AMPK pathways. Although the in vitro and in vivo studies showed promising results, further studies on humans are required to better conclude the potential role of β-carotene in managing puerperal breast inflammation.

Diabetic retinopathy leads to retinal malfunction, blindness, and reduced quality of life in adult diabetes patients. The involvement of reactive oxygen species (ROS) regulation stimulated by high blood glucose levels opens the opportunity for ROS modulator agents such as MitoTEMPOL. This study aims to explore the effect of MitoTEMPOL on ROS balance that may be correlated with retinal vascularization pattern, autophagy, and apoptosis in a streptozotocin-induced rat model. Four groups of male Wistar rats (i.e., control, TEMPOL (100 mg/kg body weight [BW]), diabetic (streptozotocin, 50 mg/kg BW single dose), and diabetic + TEMPOL; n = 5 for each group) were used in the study. MitoTEMPOL was given for 5 weeks, followed by funduscopy, and gene and protein expression were explored from the rat’s retina. Streptozotocin injection decreased bodyweight and increased food and water intake, as well as fasting blood glucose. The results showed that MitoTEMPOL reduced retinal vascularization pattern and decreased superoxide dismutase gene expression and protein carbonyl, caspase 3, and caspase 9 protein levels. A modulation of autophagy in diabetes that was reversed in the diabetic + TEMPOL group was found. In conclusion, MitoTEMPOL modulation on autophagy and apoptosis contributes to its role as a potent antioxidant to prevent diabetic retinopathy by inhibiting ROS-induced retinal vascularization patterns.

Exercise could delay the degeneration process by increasing Klotho, which is an endogen antioxidant. Klotho protects against oxidative damages, regulates hippocampal synaptic plasticity, and enhances GluN2B expression. This study aimed to analyze the effect of 14-day and 8-week moderate-intensity exercise on Klotho and GluN2B mRNA expressions in rat hippocampus. This study was an animal experimental study using Wistar rats that was performed from June to September 2019 at the Central Laboratory, Universitas Padjadjaran, Indonesia. Rats were divided into 4 groups: control (14-day control and 8-week control) and exercise group (14-day exercise and 8-week exercise). The exercise groups ran at a moderate intensity (20m/min) for 30min/day, 5x/week. Hippocampus was then subjected to klotho and GluN2B gene expression analysis. The exercise groups showed a higher Klotho expression, both in 14 days (0.844±0.124 vs. 1.057±0.013) and 8 weeks (0.897±0.072 vs. 1.380±0.168) although statistically insignificant (p=0.24). No difference in GluN2B gene expression was observed between control and exercise groups on 14 days (1±0.09 vs. 1.22±0.09) and 8 weeks (1.24±0.03 vs. 1.38±0.05; p=0.11). In conclusion, 14-day and 8-week moderate-intensity exercise did not alter Klotho and GluN2B expressions in rat hippocampus. Pengaruh Durasi Olahraga terhadap Perubahan Ekspresi Gen Klotho dan GluN2B di Hipokampus Tikus Galur Wistar yang Mendapatkan Perlakuan Lari Intensitas Sedang Olahraga dapat menghambat proses degenerasi saraf dengan meningkatkan salah satu antioksidan endogen, yaitu Klotho. Klotho dapat melindungi sel neuron dari kerusakan oksidatif dan meningkatkan sinaptik plasticity pada hipokampus. Penelitian ini bertujuan untuk melihat pengaruh olahraga lari pada hewan coba pada 14 hari dan 8 minggu terhadap perubahan ekspresi gen Klotho and GluN2B di hipokampus. Penelitian ini merupakan penelitian eksperimental dilaksanakan pada bulan Juni hingga September 2019 di Laboratorium Sentral Universitas Padjadjaran. Penelitian ini menggunakan tikus jantan galur wistar. Tikus dibagi menjadi 4 kelompok perlakuan dan kontrol. Olahraga dilakukan dengan treadmill tikus, kecepatan 20m/min, 30 menit perhari selama 5 kali perminggu. Kemudian, mRNA otak digunakan untuk PCR dengan menggunakan primer klotho dan GluN2B. Hasil penelitian menunjukkan bahwa tidak terdapat perbedaan yang bermakna (p=0.24) pada ekspresi gen Klotho pada 14 hari (0.844±0.124 vs 1.057±0.013) dan 8 minggu (0.897±0.072 vs 1.380±0.168) antara kelompok kontrol dan kelompok lari. Ekspresi gen dari GluN2B juga tidak menunjukkan perbedaan yang signifikan (p=0.11) pada 14 hari (1±0.09 vs 1.22±0.09) dan 8 minggu (1.24±0.03 vs 1.38 ± 0.05). Simpulan, bahwa 8 minggu olahraga tidak meningkatan ekspresi Klotho dan GluN2B yang signifikan

This study aims to explore the effect of mitoTEMPOL on histopathology, lipid droplet, and mitophagy gene expression of Wistar rat's liver after injection of streptozotocin (STZ).Twenty male Wistar rats were divided into 4 groups: Control (n=5); 100 mg/kg BW/day mitoTEMPOL orally (n=5); 50 mg/kg BW STZ intraperitoneal injection (n=5); and mitoTEMPOL+STZ (n=5). STZ was given a single dose, while mitoTEMPOL was given for 5 weeks after 1 week of STZ injection. Histopathological appearance, lipid droplets, mitophagy, and autophagy gene expression were examined after the mitoTEMPOL treatment.We found metabolic zone shifting that might be correlated with the liver activity of fatty acid oxidation in the STZ group, a decrease of lipid droplets in mitoTEMPOL and mitoTEMPOL + STZ compared with Control and STZ groups were found in this study. We also found significant changes in PINK1, Parkin, BNIP3, Mfn1, and LC3 gene expression, but no difference in Opa1, Fis1, Drp1, and p62 gene expression, suggesting a change of mitochondrial fusion rather than mitochondrial fission correlated with mitophagy.All this concluded that mitoTEMPOL could act as a modulator of mitophagy and metabolic function of the liver, thus amplifying its crucial role in preventing mitochondrial damage in the liver in the early onset of diabetes mellitus.

High fat diet (HFD) induces oxidative stress and mitochondrial dysfunction which culminates in fatty liver disease. Autophagy and mitochondrial dynamics are affected by HFD. Turmeric and mangosteen have potential roles as antioxidants and regulators of mitochondrial function in the liver. The study aims to examine the effect of turmeric and mangosteen peel extract on autophagy and mitochondrial dynamics in the liver after HFD induction. Five groups of animals (n=5) as used: negative control, positive control (HFD), turmeric (HFD + 270 mg/kg BW turmeric extract), mangosteen (HFD + mangosteen 270 mg/kg BW peel extract), and fenofibrate (HFD + 15 mg/kg BW fenofibrate). HFD was given for 7 weeks, continued by another 7 weeks plus treatment. Liver sections were extracted to conduct semi-quantitative PCR. Autophagy (LC3, p62), mitophagy (Pink1, Parkin, Bnip3), mitochondrial fission (Drp1, Fis1), and mitochondrial fusion (Opa1, Mfn1, Mfn2) gene expression were measured. LC3 (p=0.048), p62 (p=0.043), Pink1 (p=0.012), Bnip3 (p=0.010), Mfn1 (p=0.015), and Mfn2 (p=0.035) gene expressions were differed significantly, while Parkin (p=0.098) Drp1 (p=0.962), Fis1 (p=0.570), and Opa1 (p=0.055) gene expressions did not differ between groups. Both turmeric and mangosteen peel extract have positive effects by activating autophagy, mitophagy, and mitochondrial fusion in rat liver induced by HFD.

A myokine is one of the proteins that are produced and released by myocytes in response to muscular contractions when doing physical exercise. One protein that is thought to function as myokine is FGF23.The purpose of this study was to determine the effect of acute physical exercise with moderate intensity on the expression of FGF23 gene in Wistar rat heart. This was an animal experimental study using 24 male Wistar rats that were divided into 4 groups:treatment groups that performed 30 minute acutephysical exercise with moderate intensity (20 m/min) for 3 days, 6 days, and 15 days and a control group without physical exercise. The study was conducted in the Animal Laboratory and Central Laboratory of Universitas Padjadjaran during the period of February to July 2019. Data observed were the FGF23 gene expressions in Wistar rats heart. Data were analyzed using Kruskal-Wallis and Mann-Whitney tests. The results from the Kruskal-Wallis test showed that acute physical exercise with moderate intensity did not increase the FGF23 gene expression in Wistar rat heart (p>0.05), and the average of relative ratios of FGF23/GAPDH gene expression were as follows: control (0.970±0,03), 3 days (0.992±0.03), 6 days (1.014±0.05), and 15 days (1.056±0.02). GAPDH was used in this study as a housekeeping gene since its expression is very constant. This study proves that FGF23 is more likely to take a role in the cardiac remodeling process, especially those associated with cardiac hypertrophy after chronic exercise with no effect observed after acute physical exercise with moderate intensity in Wistar rat heart. Pengaruh Latihan Fisik Akut Intensitas Sedang terhadap Ekspresi Gen FGF23 pada Jantung Tikus Galur Wistar Miokin diproduksi dan dilepaskan oleh miosit sebagai respons terhadap latihan fisik. Salah satu protein yang diduga berfungsi sebagai miokin adalah FGF23. Penelitian ini bertujuan mengetahui pengaruh latihan fisik akut intensitas sedang terhadap ekspresi gen FGF23 pada jantung tikus galur Wistar. Penelitian ini menggunakan desain eksperimental dengan tikus galur Wistar jantan yang berjumlah 24 tikus. Tikus dibagi menjadi 4 kelompok untuk diberi perlakuan latihan fisik intensitas sedang (20 meter/menit) dengan durasi 30 menit, selama 3 hari, 6 hari, dan 15 hari serta kelompok tanpa latihan fisik. Penelitian ini dilakukan di Lab Hewan dan Lab Sentral Universitas Padjadjaran pada bulan Februari hingga Juli 2019. Ekspresi gen FGF23 pada jantung tikus galur Wistar dilihat dengan PCR. Analisis data menggunakan uji Kruskal-Wallis dan Mann-Whitney. Uji statistik tidak mendapatkan peningkatan ekspresi gen FGF23 setelah dilakukan latihan fisik akut intensitas sedang selama 3 hari, 6 hari dan 15 hari (p>0,05) dan didapatkan rasio relatif ekspresi gen FGF23/GAPDH otot jantung pada : kontrol (0,970±0,03), hari 3 (0,992±0,03), hari 6 (1,014±0,05), hari 15 (1,056±0,02). GAPDH digunakan dalam studi ini sebagai gen ‘housekeping’ karena ekspresinya yang sangat konstan. Studi ini membuktikan bahwa FGF23 mungkin lebih berperan dalam proses remodeling jantung, terutama yang berhubungan dengan hipertrofi jantung setelah latihan fisik kronik. Simpulan, tidak terdapat pengaruh latihan fisik akut intensitas sedang terhadap ekspresi gen FGF23 pada jantung tikus galur Wistar.

Exercise-induced skeletal muscle adaptation requires degradation of cellular components carried out by autophagy. However, the alteration of autophagy by different intensity of exercise in skeletal muscle is still unknown. In the present study, we investigate whether low, moderate, and high-intensity exercises have different impacts on autophagy gene expression in gastrocnemius and soleus muscles of wistar rats. This work is limited because only rats are used, and does not cover human tissues. Twenty male wistar rats were assigned to four groups: sedentary control, low-intensity (LI, 10 m/minute), moderate-intensity (MI, 20 m/minute), and high-intensity (HI, 30 m/minute) exercises. Training was conducted 30 minutes/day with a 5 times/week interval for 8 weeks. RNA and protein were extracted from gastrocnemius and soleus muscles then stored in -80°C. Specific primers and antibodies for autophagy genes and protein levels were utilized for semi-quantitative PCR and Western Blot. Exercises decrease expression of autophagy gene LC3 (LI and MI 0.7 fold, HI 0.8 fold, p < 0.05) in gastrocnemius muscles and soleus muscle (LI, MI, and HI 0.8 fold, p < 0.05) compared to control. On the other side, we observed p62 gene expression decreased in gastrocnemius (0.8 fold, p < 0.05) and soleus (0.9 fold, p < 0.05) muscles with MI, but increased in soleus (1.1 fold, p < 0.05) muscles with HI. This result is consistent with the change of protein level, suggesting that autophagy might be modulated by different type of exercise. This study suggests that intensity of exercise and different type of muscle fibers effect autophagy gene expression in skeletal muscle of wistar rats. MI exercise increases autophagy gene expression in gastrocnemius and soleus muscles, but HI exercise decreases autophagy gene expression in soleus muscles of wistar rats. Soleus muscles are more responsive to exercise compared to gastrocnemius muscles.

Yes-associated protein (YAP) is one of the Hippo pathway's two effectors, a pathway associated with organ size control. Research on YAP has focused on its oncogenic potential. However, in cancer cells, aside from inducing growth, YAP was also found to regulate glucose metabolism. Therefore, we aimed to explore YAP's control of glucose metabolism and whether these findings are translatable to physiological conditions. We conducted a systematic review of the MEDLINE database through PubMed in April 2020 and repeated the search in September 2020. We found that YAP induced the transcriptional activity of most genes associated with glucose metabolism from enzymes to transport proteins. In glycolysis and gluconeogenesis, YAP upregulated all enzymes except for enolase and pyruvate kinase. Multiple research has also shown YAP's ability to regulate the expression of glucose transporter of the GLUT family. Additionally, glucose concentration, hypoxia, and hormones such as insulin and glucagon regulate YAP activity and depend on YAP to exert their biological activity. In this review, we have shown that YAP is a central regulator of glucose metabolism, controlling both enzymes and proteins involved in glucose transport. YAP is also situated strategically in several pathways controlling glucose and was found to mediate their effects. If these results were consistent in physiological conditions and across glucose-associated metabolic disturbances, then YAP may become a prospective therapeutic target.

Introduction Aerobic training has a beneficial effect on enhancing liver functions. Autophagy might potentially play a role in preventing excessive lipid accumulation, regulating oxidative stress, and inflammation in the liver. Objective To investigate the potential linking role of autophagy-related gene expressions and protein levels with histopathology changes in Wistar rat livers after treadmill training under different intensities. Methods 20 rats were divided into 4 groups (control, low intensity, moderate intensity, and high intensity). 8 weeks of treadmill training was conducted with a frequency of 5 days per week, for a duration of 30 min per day. Liver histopathology was studied using hematoxylin-eosin, and oil red O staining. RNA and protein from the liver tissues were extracted to examine the autophagy-related gene (LC3, p62) and protein levels (Beclin, ATG5, LC3, p62). The gene expressions of CPT1a, CD36, FATP 2,3,5, GLUT2, and FGF21 were also studied. Results Different intensities of training might potentially modulate autophagy-related gene expressions in rat livers. LC3 and p62 mRNA expressions in moderate and high intensities decreased compared to control. Beclin, ATG5, and LC3 protein level increased compared to control, while p62 protein level decreased compared to control. Whereas for the other genes, we found an increase in CPT1a, but we did not observed any changes in the expression of the other genes. Interestingly, autophagy-related gene expressions might be correlated with the changes of sinusoidal dilatation, cloudy swelling, inflammation, and lipid droplets of the liver tissues. Conclusion Moderate and high intensities of training induce autophagy activity, combined with a shift in metabolic zonation in liver that might be potentially correlated with lipophagy. Our results showed the potential interplay role between autophagy and liver histopathology appearances as a part of the adaptation process to training., Biological sciences; Exercise; Animal physiology; Health sciences; Physiology; Treadmill training; Lipid droplets; Autophagy; Lipophagy; Histopathology

Tranexamic acid (TSA) is widely used as an antiaging treatment for reducing melasma and wrinkles. There are various mechanisms for wrinkle formation, and one of them is due to damage of the mitochondria. Research on mitochondria in the skin is very limited, so we are interested to see the changes that occur after application of TSA cream. We explored the effect of TSA on mitochondrial protein levels (PGC1α, Tom20, COX IV), which had affected to skin histological structure. Thirty male, 6-week-old, Balb/C mice were divided into five groups (negative control, positive control, TSA 3%, TSA 4% and TSA 5%). After 10 days of acclimatization, four groups of mice were exposed to UVB light, of which three groups were given TSA cream for 10 weeks. The skin tissue was excised for protein and histological studies. H&E staining was performed for evaluating histological changes in epidermal thickness and dermal elastosis. TSA treatment on the mice skin increased mitochondrial marker levels and epidermal thickness while decreasing dermal elastosis for all the treatment groups. Topical application of TSA significantly increased mitochondrial biogenesis which may cause alteration in epidermal thickness and reduced dermal elastosis in the histology of mice skin.

Background The mechanism for cardiac hypertrophy process that would be a benefit for improvement of cardiovascular endurance needed to be investigated throughly. Specific intensity of training may play a role for homeostasis process in cardiac during training. In the present study, we examine the effect of different intensity of treadmill training on cardiac hypertrophy process and autophagy related gene expression in male wistar rats. Methods Three different intensities of treadmill training were conducted on 15 male wistar rats (Low Intensity: 10 m/minute, Moderate Intensity: 20 m/minute, and High Intensity: 30 m/minute) compared to 5 sedentary rats as control. Training duration was 30 min per day, frequency was 5 days per week, during 8 weeks period. Heart weight and heart weight/body weight ratio were measured after the experiments. Left ventricle myocardium was taken for microscopic analysis with HE staining. mRNA was extracted from left ventricle myocardium for examining αMHC and autophagy related gene expression (PIK3CA, mTOR, LC3, p62) using semi quantitative PCR. Results We observed that altered training intensity might stimulate cardiac hypertrophy process. MI and HI training increased heart weight and heart weight/body weight ratio. This finding is supported by microscopic result in which cardiac hypertrophy was found in MI and HI, with focal fibrosis in HI, and increased αMHC gene expression in MI (p

Exercise-induced skeletal muscle adaptation requires degradation of cellular components carried out by autophagy. However, the alteration of autophagy by different intensity of exercise in skeletal muscle is still unknown. In the present study, we investigate whether low, moderate, and high-intensity exercises have different impacts on autophagy gene expression in gastrocnemius and soleus muscles of wistar rats. This work is limited because only rats are used, and does not cover human tissues. Twenty male wistar rats were assigned to four groups: sedentary control, low-intensity (LI, 10 m/minute), moderate-intensity (MI, 20 m/minute), and high-intensity (HI, 30 m/minute) exercises. Training was conducted 30 minutes/day with a 5 times/week interval for 8 weeks. RNA and protein were extracted from gastrocnemius and soleus muscles then stored in -80°C. Specific primers and antibodies for autophagy genes and protein levels were utilized for semi-quantitative PCR and Western Blot. Exercises decrease expression of autophagy gene LC3 (LI and MI 0.7 fold, HI 0.8 fold, p < 0.05) in gastrocnemius muscles and soleus muscle (LI, MI, and HI 0.8 fold, p < 0.05) compared to control. On the other side, we observed p62 gene expression decreased in gastrocnemius (0.8 fold, p < 0.05) and soleus (0.9 fold, p < 0.05) muscles with MI, but increased in soleus (1.1 fold, p < 0.05) muscles with HI. This result is consistent with the change of protein level, suggesting that autophagy might be modulated by different type of exercise. This study suggests that intensity of exercise and different type of muscle fibers effect autophagy gene expression in skeletal muscle of wistar rats. MI exercise increases autophagy gene expression in gastrocnemius and soleus muscles, but HI exercise decreases autophagy gene expression in soleus muscles of wistar rats. Soleus muscles are more responsive to exercise compared to gastrocnemius muscles.

The use of Kinesio Taping has been reported to increase muscle power and strength,especially quadriceps femoris muscle, the great extensor of the leg. This research examines theeffect of Kinesio Taping on quadriceps femoris muscle power and strength in non-athlete adultmales. This research is quasi experimental design, involving 30 non-athlete adult males aged18-22 years old . Muscle power is examined by using Margaria-KalamenPower Test, andmuscle strength by using Isometric Leg Strength Test before, 20 minutes and 24 hours afterusing Kinesio Taping. The data is analyzed by using paired t test. The result shows that musclepower difference between 20 minutes and before using KinesioTaping (196,62±150,67) watt arelower than muscle power difference between 24 hours and before using KinesioTaping(247,31±139,88)watt (p value
