Physical Training vs. Perindopril Treatment on Arterial Stiffening of Spontaneously Hypertensive Rats: A Proteomic Analysis and Possible Mechanisms. Biomedicines 2023; 11:biomedicines11051381. [PMID: 37239052 DOI: 10.3390/biomedicines11051381] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 04/21/2023] [Accepted: 05/02/2023] [Indexed: 05/28/2023] Open
Abstract
(1) Background: Arterial stiffness is an important predictor of cardiovascular events. Perindopril and physical exercise are important in controlling hypertension and arterial stiffness, but the mechanisms are unclear. (2) Methods: Thirty-two spontaneously hypertensive rats (SHR) were evaluated for eight weeks: SHRC (sedentary); SHRP (sedentary treated with perindopril-3 mg/kg) and SHRT (trained). Pulse wave velocity (PWV) analysis was performed, and the aorta was collected for proteomic analysis. (3) Results: Both treatments determined a similar reduction in PWV (-33% for SHRP and -23% for SHRT) vs. SHRC, as well as in BP. Among the altered proteins, the proteomic analysis identified an upregulation of the EH domain-containing 2 (EHD2) protein in the SHRP group, required for nitric oxide-dependent vessel relaxation. The SHRT group showed downregulation of collagen-1 (COL1). Accordingly, SHRP showed an increase (+69%) in the e-NOS protein level and SHRT showed a lower COL1 protein level (-46%) compared with SHRC. (4) Conclusions: Both perindopril and aerobic training reduced arterial stiffness in SHR; however, the results suggest that the mechanisms can be distinct. While treatment with perindopril increased EHD2, a protein involved in vessel relaxation, aerobic training decreased COL1 protein level, an important protein of the extracellular matrix (ECM) that normally enhances vessel rigidity.

Molecular mechanisms underlying hypertensive effect of fructose and the preventive properties of inulin - Global transcriptomic analysis in rat aorta. Nutr Metab Cardiovasc Dis 2023; 33:441-456.

Abstract
BACKGROUND AND AIMS Excessive intake of fructose is a significant contributor in the development of hypertension and pathogenesis of cardiometabolic diseases. We previously showed that dietary inulin can prevent fructose-induced hypertension in rats. Nevertheless, molecular mechanisms of both fructose and inulin in aorta remain unknown. The aim of this study was to identify global transcriptomic changes in aorta in rats on fructose-based diet or partial substitution of dietary fructose with inulin. METHODS AND RESULTS At the end of study periods, aortas were isolated, RNA extracted, and transcriptomics performed using microarrays followed by in-dept bioinformatic analyses. We observed that fructose-based diet affected the expression of over 1700 genes involved in the regulation of vascular functions, cell signaling, and cellular metabolism. Partial substitution of dietary fructose with inulin affected the expression of over 1300 genes regulating endothelial and vascular functions, including relaxin signaling pathway, immune/inflammatory response, or cellular metabolism. Bioinformatic analyses revealed transcription factors, such as Junb or Nr4a2, and miRNAs, such as miR-206, miR-137 or miR-375, as potential transcriptional and post-transcriptional regulators of identified differentially expressed genes. Genes identified following both diets are associated with development of cardiovascular diseases, hypertension, immune system diseases and metabolic diseases. Moreover, a negative correlation between the expression profiles obtained by fructose-based diet and that by partial substitution of dietary fructose with inulin was observed. CONCLUSION Our study showed that fructose can significantly impact global transcriptomic profile in aorta, changes that can be counteracted by inulin and which present relevant molecular mechanisms underlying its anti-hypertensive property.

Genetic Factors for Coronary Heart Disease and Their Mechanisms: A Meta-Analysis and Comprehensive Review of Common Variants from Genome-Wide Association Studies. Diagnostics (Basel) 2022; 12:diagnostics12102561. [PMID: 36292250 PMCID: PMC9601486 DOI: 10.3390/diagnostics12102561] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 10/18/2022] [Accepted: 10/20/2022] [Indexed: 11/17/2022] Open
Abstract
Genome-wide association studies (GWAS) have discovered 163 loci related to coronary heart disease (CHD). Most GWAS have emphasized pathways related to single-nucleotide polymorphisms (SNPs) that reached genome-wide significance in their reports, while identification of CHD pathways based on the combination of all published GWAS involving various ethnicities has yet to be performed. We conducted a systematic search for articles with comprehensive GWAS data in the GWAS Catalog and PubMed, followed by a meta-analysis of the top recurring SNPs from ≥2 different articles using random or fixed-effect models according to Cochran Q and I2 statistics, and pathway enrichment analysis. Meta-analyses showed significance for 265 of 309 recurring SNPs. Enrichment analysis returned 107 significant pathways, including lipoprotein and lipid metabolisms (rs7412, rs6511720, rs11591147, rs1412444, rs11172113, rs11057830, rs4299376), atherogenesis (rs7500448, rs6504218, rs3918226, rs7623687), shared cardiovascular pathways (rs72689147, rs1800449, rs7568458), diabetes-related pathways (rs200787930, rs12146487, rs6129767), hepatitis C virus infection/hepatocellular carcinoma (rs73045269/rs8108632, rs56062135, rs188378669, rs4845625, rs11838776), and miR-29b-3p pathways (rs116843064, rs11617955, rs146092501, rs11838776, rs73045269/rs8108632). In this meta-analysis, the identification of various genetic factors and their associated pathways associated with CHD denotes the complexity of the disease. This provides an opportunity for the future development of novel CHD genetic risk scores relevant to personalized and precision medicine.

Benefits of combined exercise training on arterial stiffness and blood pressure in spontaneously hypertensive rats treated or not with dexamethasone. Front Physiol 2022; 13:916179.

Abstract
Dexamethasone (DEX)-induced arterial stiffness is an important side-effect, associated with hypertension and future cardiovascular events, which can be counteracted by exercise training. The aim of this study was to evaluate the mechanisms induced by combined training to attenuate arterial stiffness and hypertension in spontaneously hypertensive rats treated or not with dexamethasone. Spontaneously hypertensive rats (SHR) underwent combined training for 74 days and were treated with dexamethasone (50 µg/kg s. c.) or saline solution during the last 14 days. Wistar rats were used as controls. Echocardiographic parameters, blood pressure (BP) and pulse wave velocity (PWV), as well as histological analyses of the heart and aorta, carotid and femoral arteries were performed. At the beginning, SHR had higher BP and PWV compared with Wistar rats. After 60 days, while BP increased in sedentary SHR, combined exercise training decreased BP and PWV. After 74d, the higher BP and PWV of sedentary SHR was accompanied by autonomic imbalance to the heart, cardiac remodeling, and higher arterial collagen deposition. DEX treatment did not change these parameters. On the other hand, trained SHR had reduced BP and PWV, which was associated with better autonomic balance to the heart, reduced myocardial collagen deposition, as well as lower arterial collagen deposition. The results of this study suggest that combined training, through the reduction of aortic collagen deposition, is an important strategy to reduce arterial stiffness in spontaneously hypertensive rats, and these lower responses were maintained regardless of dexamethasone treatment.

Abstract
PURPOSE We compared central and peripheral arterial stiffness response patterns between persons with and without intellectual and developmental disabilities (IDD) of different age groups at rest and following a cardiopulmonary exercise test (CPET). METHODS 15 young adults with and without IDD, and 15 middle-aged adults without IDD performed a CPET. Central and peripheral arterial stiffness were measured at rest and following CPET using estimates of carotid-femoral (cfPWV), carotid-radial (crPWV), and carotid-ankle (cdPWV) pulse wave velocity derived from piezoelectric mechano-transducers. RESULTS cfPWV remained unchanged following CPET in adults with and without IDD but increased in middle-aged adults (d= 0.85; 95% CI: 0.27 to 1.42 m.s-1, p= 0.005), whereas cdPWV was similarly reduced (d= -0.77; 95% CI: -1.06 to -0.48 m.s-1, p< 0.001) in all groups. crPWV remained unchanged in all groups. These results were independent of exercise-related changes in mean arterial pressure. Overall group differences suggested that persons with IDD (d = - 1.78; 95% CI: -3.20 to -0.37 m.s-1, p= 0.009) and without IDD (d = -1.84; 95% CI: -3.26 to -0.43 m.s-1, p= 0.007) had lower cfPWV than middle-aged adults. CONCLUSION We found no evidence of early vascular aging and diminished vascular reserve following CPET in adults with IDD.

Abstract
In recent years, there has been an increasing interest in space exploration, supported by the accelerated technological advancements in the field. This has led to a new potential environment that humans could be exposed to in the very near future, and therefore an increasing request to evaluate the impact this may have on our body, including health risks associated with this endeavor. A critical component in regulating the human pathophysiology is represented by the cardiovascular system, which may be heavily affected in these extreme environments of microgravity and radiation. This mini review aims to identify the impact of microgravity and radiation on the cardiovascular system. Being able to understand the effect that comes with deep space explorations, including that of microgravity and space radiation, may also allow us to get a deeper understanding of the heart and ultimately our own basic physiological processes. This information may unlock new factors to consider with space exploration whilst simultaneously increasing our knowledge of the cardiovascular system and potentially associated diseases.
