Eccentric contraction may lead to better power production characteristics of the muscle because eccentric contraction requires less energy and can result in higher tension. Therefore, it is an ideal tool in the rehabilitation program of patients. However, the complex metabolic effect (i.e., fat mass reduction, increased lipid oxidation, improvement in blood lipid profile, and increased insulin sensitivity) of the eccentric contraction alone has scarcely been investigated. This paper aims to review the current literature to provide information on whether eccentric contraction can influence metabolic health and body composition in T2DM or obesity. We also discussed the potential role of myokines in mediating the effects of eccentric exercise.

EMS treatment via skeletal muscle activity improves the cardiovascular functions and the overall physical condition of the patients. However, the cardioprotective effect of EMS has not been proven so far, therefore, the aim of this study was to investigate the potential cardiac conditioning effect of EMS in an animal model. Low-frequency 35-min EMS was applied to the gastrocnemius muscle of male Wistar rats for three consecutive days. Their isolated hearts were then subjected to 30 min global ischemia and 120 min reperfusion. At the end of reperfusion cardiac specific creatine kinase (CK-MB) and lactate dehydrogenase (LDH) enzyme release and myocardial infarct size were determined. Additionally, skeletal muscle-driven myokine expression and release were also assessed. Phosphorylation of cardioprotective signaling pathway members AKT, ERK1/2, and STAT3 proteins were also measured. EMS significantly attenuated cardiac LDH and CK-MB enzyme activities in the coronary effluents at the end of the ex vivo reperfusion. EMS treatment considerably altered the myokine content of the stimulated gastrocnemius muscle without altering circulating myokine levels in the serum. Additionally, phosphorylation of cardiac AKT, ERK1/2, and STAT3 was not significantly different in the two groups. Despite the lack of significant infarct size reduction, the EMS treatment seems to influence the course of cellular damage due to ischemia/reperfusion and favorably modifies skeletal muscle myokine expressions.

One of the main causes of neurodegeneration in HD is transcriptional dysregulation that, in part, is caused by the inhibition of histone acetyltransferase (HAT) enzymes. HD pathology can be alleviated by increasing the activity of specific HATs or by inhibiting histone deacetylase (HDAC) enzymes. To determine which histone’s post-translational modifications (PTMs) might play crucial roles in HD pathology, we investigated the phenotype-modifying effects of PTM mimetic mutations of variant histone H3.3 in a Drosophila model of HD. Specifically, we studied the mutations (K→Q: acetylated; K→R: non-modified; and K→M: methylated) of lysine residues K9, K14, and K27 of transgenic H3.3. In the case of H3.3K14Q modification, we observed the amelioration of all tested phenotypes (viability, longevity, neurodegeneration, motor activity, and circadian rhythm defects), while H3.3K14R had the opposite effect. H3.3K14Q expression prevented the negative effects of reduced Gcn5 (a HAT acting on H3K14) on HD pathology, while it only partially hindered the positive effects of heterozygous Sirt1 (an HDAC acting on H3K14). Thus, we conclude that the Gcn5-dependent acetylation of H3.3K14 might be an important epigenetic contributor to HD pathology.}, year = {2022}, eissn = {1422-0067}, orcid-numbers = {Zsindely, Nóra/0000-0002-6189-3100; Szabó, Márton Richárd/0000-0003-0415-5192; Csont, Tamás Bálint/0000-0001-5792-2768; Bodai, László/0000-0001-8411-626X} } @{MTMT:33104875, title = {The cytoprotective effect of kynurenic acid against simulated ischemia/reoxygenation-induced damage of cardiac cells}, url = {https://m2.mtmt.hu/api/publication/33104875}, author = {Nógrádi-Halmi, Dóra and Molnár-Gáspár, Renáta and Csontné Kiricsi, Mónika and Nóra, Igaz and Csont, Tamás Bálint}, booktitle = {Abstract book of Annual Meeting of the Hungarian Biochemical Society 2022}, unique-id = {33104875}, year = {2022}, pages = {91}, orcid-numbers = {Nógrádi-Halmi, Dóra/0000-0001-9496-9354; Molnár-Gáspár, Renáta/0000-0001-9673-4532; Csontné Kiricsi, Mónika/0000-0002-8416-2052; Csont, Tamás Bálint/0000-0001-5792-2768} } @{MTMT:33032074, title = {MicroRNA-based therapeutic strategies for chronic kidney disease and uremic cardiomyopathy [Chapter 28]}, url = {https://m2.mtmt.hu/api/publication/33032074}, author = {Sárközy, Márta and Csont, Tamás Bálint}, booktitle = {MicroRNA}, doi = {10.1016/B978-0-323-89774-7.00006-6}, unique-id = {33032074}, year = {2022}, pages = {563-600}, orcid-numbers = {Sárközy, Márta/0000-0002-5929-2146; Csont, Tamás Bálint/0000-0001-5792-2768} } @article{MTMT:32924828, title = {Diet-Induced Hypercholesterolemia Leads to Cardiac Dysfunction and Alterations in the Myocardial Proteome}, url = {https://m2.mtmt.hu/api/publication/32924828}, author = {Szabó, Márton Richárd and Pipicz, Márton and Sárközy, Márta and Bruszel, Bella and Szabó, Zoltán and Csont, Tamás Bálint}, doi = {10.3390/ijms23137387}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {23}, unique-id = {32924828}, issn = {1661-6596}, abstract = {Elevated blood cholesterol is a major risk factor for coronary heart disease.

Male Wistar rats were fed with a laboratory rodent chow supplemented with 2% cholesterol for 8 weeks to induce hypercholesterolemia. The protein expression data obtained from the proteomic characterization of left ventricular samples from normo- and hypercholesterolemic animals were subjected to gene ontology (GO) and protein interaction analyses. Elevated circulating cholesterol levels were accompanied by diastolic dysfunction in cholesterol-fed rats. The proteomic characterization of left ventricular samples revealed altered expression of 45 proteins due to hypercholesterolemia. Based on the Gene Ontology analysis, hypercholesterolemia was associated with disturbed expression of cytoskeletal and contractile proteins. Beta-actin was downregulated in the hypercholesterolemic myocardium, and established a prominent hub of the protein interaction network. Analysis of the unfiltered dataset revealed concordant downregulated expression patterns in proteins associated with the arrangement of the contractile system (e.g., cardiac-specific troponins and myosin complex), and in subunits of the mitochondrial respiratory chain.
