Egypt Heart J 2024; 76:1. [PMID: 38165587 PMCID: PMC10761650 DOI: 10.1186/s43044-023-00430-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Accepted: 12/15/2023] [Indexed: 01/04/2024] Open
Abstract
BACKGROUND Coronary artery disease (CAD) is the main cause of death in Egypt. Many LDL-R gene locus single nucleotide polymorphisms (SNP) are found to be associated with the risk of CAD. This research aimed to assess the allelic and genotypic frequencies of rs1122608 SNP and their association with the extent of vessel affection and lipid profile in a population of Egyptians.100 CAD patients and 100 healthy controls of Egyptians were included. PCR-RFLP was used to genotype rs1122608 SNPs. RESULTS Significantly higher proportion of 'T' allele among patient (risk allele). This association is of low strength (ϕ lies between 0.1 and 0.3). A participant with 'T' allele has 1.95 times higher odds to exhibit CAD versus a participant with 'G' allele. Significantly higher proportion of 'T/T' genotype among cases versus control (risk genotype). This association is of low strength (Cramer's V lies between 0.1 and 0.3). A participant with 'T/T' genotype has 4.5 times higher odds to exhibit CAD versus a participant with 'G/G'. Gensini score showed no significant association with rs1122608 genotypes (p = 0.863). CONCLUSIONS The mutant GT and TT genotypes and minor T allele of rs1122608 were positively correlated with CAD and considered as independent risk factors for CAD.

Abstract
Recently, single cell RNA sequencing (scRNA-seq) technology has enabled the discovery of novel or rare subtypes of cells and their characteristics. This technique has advanced unprecedented biomedical research by enabling the profiling and analysis of the transcriptomes of single cells at high resolution and throughput. Thus, scRNA-seq has contributed to recent advances in cardiovascular research by the generation of cell atlases of heart and blood vessels and the elucidation of mechanisms involved in cardiovascular development and diseases. This review summarizes the overall workflow of the scRNA-seq technique itself and key findings in the cardiovascular development and diseases based on the previous studies. In particular, we focused on how the single-cell sequencing technology can be utilized in clinical field and precision medicine to treat specific diseases.

Abstract
Introduction: Emerging evidence suggests that Chemotherapy (CT) treated breast cancer survivors (BCS) who have "risk variants" in genes may be more susceptible to cognitive impairment (CI) and/or poor cardiac phenotypes. The objective of this preliminary study was to examine whether there is a relationship between genetic variants and objective/subjective cognitive or cardiac phenotypes. Methods and Analysis: BCS were recruited from Moffitt Cancer Center, Morsani College of Medicine, AdventHealth Tampa and Sarasota Memorial Hospital. Genomic DNA were collected at baseline for genotyping analysis. A total of 16 single nucleotide polymorphisms (SNPs) from 14 genes involved in cognitive or cardiac function were evaluated. Three genetic models (additive, dominant, and recessive) were used to test correlation coefficients between genetic variants and objective/subjective measures of cognitive functioning and cardiac outcomes (heart rate, diastolic blood pressure, systolic blood pressure, respiration rate, and oxygen saturation). Results: BCS (207 participants) with a mean age of 56 enrolled in this study. The majority were non-Hispanic white (73.7%), married (63.1%), and received both CT and radiation treatment (77.3%). Three SNPs in genes related to cognitive functioning (rs429358 in APOE, rs1800497 in ANKK1, rs10119 in TOMM40) emerged with the most consistent significant relationship with cognitive outcomes. Among five candidate SNPs related to cardiac functioning, rs8055236 in CDH13 and rs1801133 in MTHER emerged with potential significant relationships with cardiac phenotype. Conclusions: These preliminary results provide initial targets to further examine whether BCS with specific genetic profiles may preferentially benefit from interventions designed to improve cognitive and cardiac functioning following CT.

Abstract
Although lipid-lowering therapy has become a mainstay in preventive cardiology, many people do not realize how individual's genetic information and current genetic knowledge can be used in clinical practice. Genetic testing is one of the methods to find etiology in monogenic or polygenic dyslipidemia. Pharmacogenetic data may provide guidance for selection of treatment-eligible patients and lipid-lowering therapeutics. In addition, recent progress in research regarding genetics, bioinformatics, and pharmacological platforms accelerated drug target discovery and drug development in the field of dyslipidemia and cardiovascular disease prevention. Dyslipidemia is a strong risk factor for cardiovascular disease as well as a major target for its prevention. Along with the progress in genetic research techniques and bioinformatics analysis, genetic knowledge helps manage individuals with dyslipidemia. Familial hypercholesterolemia, the most common monogenic lipid disorder, can be diagnosed clinically without confirming pathogenic mutations. However, it can be difficult to do so due to uncertain family history, and genetic testing is of vital importance in such cases. Conversely, recent studies have revealed that combination effect of rare and common variants is frequent in people with other extreme lipid phenotypes. Genetic characteristics are helpful for prediction and selection of patients with high risk for cardiovascular disease or poor response to lipid-lowering therapy. In the past decade, studies using new genetic techniques have identified novel associations among lipid metabolism-associated genes, intermediate lipid phenotypes, and cardiovascular health. Such findings shed light on new drug targets. With improvements in the platforms and processes for drug development, several recent clinical trials showed promising results regarding lipid control and potential cardiovascular disease prevention.
