The increasing rate of cardiovascular disease (CVD) worldwide contributes to a worsening quality life in surviving patients and socioeconomic burden on the health care system. There is currently no cure for CVD. innovation novel therapies has traditionally been significantly stalled due several obstacles, such as complications resulting from scar tissue formation need representative patient-specific cardiac model. However, last two decades have seen emergence induced pluripotent stem cells (iPSCs), which risen at forefront regenerative medicine research cell source. In this chapter, we will cover basics reprogramming, iPSC generation, assessment before moving versatile array roles that iPSCs hold. We outline three potential uses heart regeneration research: precursor an vitro model, vivo implantation purposes, source secretome. Finally, aim highlight importance incorporating biological characteristics within large-scale identify gaps applications medicine.

Physiological levels of reactive oxygen and nitrogen species (ROS/RNS) function as fundamental messengers for many cellular developmental processes in the cardiovascular system. ROS/RNS involved cardiac redox-signaling originate from diverse sources, their are tightly controlled by key endogenous antioxidant systems that counteract accumulation. However, dysregulated redox-stress resulting inefficient removal leads to inflammation, mitochondrial dysfunction, cell death, contributing development progression disease (CVD).

Abstract Immune checkpoint inhibitors (ICIs) exhibit remarkable antitumor activity and immune-related cardiotoxicity of unknown pathomechanism. The aim the study was to investigate ICI class-dependent in vitro pembrolizumab’s (Pem’s) vivo, seeking for translational prevention means. Cytotoxicity investigated primary cardiomyocytes splenocytes, incubated with ipilimumab, Pem avelumab.

Abstract Introduction SARS-CoV-2 infection causes severe endothelial damage, an essential step for cardiovascular complications. Endothelial-colony forming cells (ECFCs) act as a biomarker of vascular damage but their role in remain unclear. The aim this study was to assess whether the number ECFCs and angiogenic biomarkers remained altered after 6 12-months post-infection imbalance correlated with presence long-COVID syndrome other biological parameters measured. Methods Seventy-two patients were recruited at different time-points overcoming COVID-19 thirty-one healthy controls. All subjects matched age, gender, BMI, comorbidities. obtained from peripheral blood cultured specific conditions. Results results confirm long-term sequela post-COVID-19 patients, abnormal increase ECFC production compared controls (82.8% vs . 48.4%, P < 0.01) that is maintained up 6-months (87.0% (85.0% vs. 0.01). Interestingly, showed significant downregulation angiogenesis-related proteins indicating clear injury. Troponin, NT-proBNP ferritin levels, markers risk inflammation, elevated post-infection. Patients lower numbers exhibited higher levels inflammatory markers, such ferritin, suggesting may play protective role. Additionally, associated female gender. Conclusions These findings highlight last 6- point out need preventive measures patient follow-up.

Highlights A fundamental distinguishing feature of normal endothelial cell morphotypes from pathological ones is their preserved orientation along the direction blood flow in absence cytoplasmic or membrane defects. The main characteristics dysfunctional cells include a spherical shape (indicating loss cellular flow), presence large vacuoles within cell, vacuolization, impaired plasma integrity, reduced contrast between nucleus and cytoplasm, partial detachment basement membrane. condition organelles (mitochondria, Golgi complex, endoplasmic reticulum) integrity are not sensitive specific markers endothelium compared to aforementioned features Aim. To analyze electron microscopic using descending aorta rats (characterized by laminar flow). Methods. study was conducted on 5 male Wistar (age ≈ 6 months, body weight 500 g). extracted aortas were chemically fixed 2.5% glutaraldehyde, post-fixed 1% osmium tetroxide solution with 1.5% potassium ferrocyanide, incubated thiocarbohydrazide, stained 2% aqueous solution, contrasted phosphotungstic acid, gadolinium triacetate, dehydrated ascending concentrations ethanol, isopropanol, acetone, embedded mixture acetone epoxy resin, then pure Araldite 502 followed its polymerization. After grinding polishing, samples lead citrate, coated carbon, visualized backscattered scanning microscopy. Results. Electron analysis identified three cells: 1) elongated an nucleus; semicircular oval, round, kidney-shaped, polymorphic less pronounced but clearly visible flow; 3) even flow. often contained various Dysfunctional also exhibited several morphotypes, characterized different combinations following features: flow, disruption However, changes structure adjacent observed cells. Conclusion. preservation indicates phenotype other signs (vacuoles membrane).

Abstract Acute myocardial infarction (AMI) is a leading cause of mortality worldwide. MicroRNAs (miRNAs), among other small non-coding RNAs, shape the transcriptome and control cellular functions. Although single-cell technologies are now available to study ischemia response, RNA regulation limited by depth expression, capture efficiency lack full coverage transcripts. In addition, kinetic expression miRNAs unknown. Using paired total sequencing, we built an atlas temporal dynamics genes in four major heart cell types after AMI. Expression reveal enriched functions highlighting type-specific AMI stress responses. Many deregulated mouse overlap with known human cardiovascular disease genes. The dataset highly valuable for additional research on long such as variants splicing or alternative ORFs. All all, provides useful resource different roles RNAs

Long non-coding RNAs (lncRNAs) can act as regulatory which, by altering the expression of target genes, impact on cellular phenotype and cardiovascular disease development. Endothelial lncRNAs their vascular functions are largely undefined. Deep RNA-Seq FANTOM5 CAGE analysis revealed lncRNA LINC00607 to be highly enriched in human endothelial cells. was induced response hypoxia, arteriosclerosis regression non-human primates, post-atherosclerotic cultured cells from patients also propranolol used induce arteriovenous malformations. siRNA knockdown or CRISPR/Cas9 knockout attenuated VEGF-A-induced angiogenic sprouting. integrated less into newly formed networks an vivo assay SCID mice. Overexpression CRISPR restored normal function. RNA- ATAC-Seq after changes transcription gene sets linked chromatin accessibility around ERG-binding sites. Mechanistically, interacted with SWI/SNF remodeling protein BRG1. CRISPR/Cas9-mediated BRG1 HUVEC followed CUT&RUN that is required secure a stable state, mainly In conclusion, endothelial-enriched maintains ERG interacting remodeler ultimately mediate angiogenesis.

Myocardial infarction (MI) is one of the leading causes death in Western countries. An early diagnosis decreases subsequent severe complications such as wall remodeling or heart failure and improves treatments interventions. Novel therapeutic targets have been recognized and, together with development direct indirect epidrugs, role non-coding RNAs (ncRNAs) yields great expectancy. ncRNAs are a group not translated into product among them, microRNAs (miRNAs) most investigated subgroup since they involved several pathological processes related to MI post-MI phases inflammation, apoptosis, angiogenesis, fibrosis. These pathways finely tuned by miRNAs via complex mechanisms. We at beginning investigation main paths still underexplored. In this review, we provide comprehensive discussion recent findings on epigenetic changes first after well miRNAs. focused function their relationship key molecules cells healing an ischemic accident, while also giving insight discrepancy between males females prognosis cardiovascular diseases.
