引用

World Journal of Cardiovascular Diseases 2024年第3期14卷 115-128页

Background: Hypertension, also known as increased blood pressure, is a phenomenon in which blood flows in blood vessels and causes persistently.higher-than-normal pressure on the vessel wall. The identification of novel prognostic and pathogenesis biomarkers plays a key role in the management of hypertension. Methods: The GSE7483 and GSE75815 datasets from the gene expression omnibus (GEO) database were used to identify the genes associated with hypertension that were differentially.expressed genes (DEGs). The functional role of the DEGs was elucidated by gene body (GO) enrichment analy.is. In addition, we performed an immune infiltration assay and GSEA on the DEGs of hypertensive patients and verified the expression of novel DEGs in the blood of hypertensive patients by RT-qPCR. Results: A total of 267 DEGs were identified from the GEO database. GO analy.is revealed that these genes were associated mainly.with biological processes such as fibroblast proliferation, cell structural organization, extracellular matrix organization, vasculature development regulation, and angiogenesis. We identified five possible biomarkers, Ecm1, Sparc, Sphk1, Thbsl, and Mecp2, which correlate with vascular development and angiogenesis characteristic of hypertension by bioinformatics, and explored the clinical expression levels of these genes by RT-qPCR, and found that Sparc, Sphk1, and Thbs1 showed significant up-regulation, in agreement with the results of the bioinformatics analy.is. Conclusion: Our study suggested that Sparc, Sphk1 and Thbs1 may be potential novel biomarkers for the diagnosis, treatment and prognosis of hypertension and that they are involved in the regulation of vascular development and angiogenesis in hypertension.

Identification and Validation of Novel Biomarkers Related to the Calcium Metabolism Pathway in Hypertension Patients Based on Comprehensive Bioinformatics Methods

Health 2024年第3期16卷 173-186页

Background: Hypertension is a universal risk factor for cardiovascular diseases and is thus the leading cause of death worldwide. The identification of novel prognostic and pathogenesis biomarkers plays a key role in disease management. Methods: The GSE145854 and GSE164494 datasets were downloaded from the Gene Expression Omnibus (GEO) database and used for screening and validating hypertension signature genes, respectively. Gene Ontology (GO) enrichment analy.is was performed on the differentially.expressed genes (DEGs) related to calcium ion metabolism in patients with hypertension. The core genes related to immune infiltration were analy.ed and screened, and the activity of the signature genes and related pathways was quantified using gene set enrichment analy.is (GSEA). The infiltration of immune cells in the blood samples was analy.ed, and the DEGs that were abnormally.expressed in the clinical blood samples of patients with hypertension were verified via RT-qPCR. Results: A total of 176 DEGs were screened. GO showed that DEGs was involved in the regulation of calcium ion metabolism in biological processes (BP), actin mediated cell contraction, negative regulation of cell movement, and calcium ion transmembrane transport, and in the regulation of protease activity in molecular functions (MF). KEGG analy.is revealed that the DEGs were involved mainly.in the cGMP-PKG signaling pathway, ubiquitin-protein transferase, tight junction-associated proteins, and the regulation of myocardial cells. MF analy.is revealed the immune infiltration function of the cells. RT-qPCR revealed that the expression of Cacna1d, Serpine1, Slc8a3, and Trpc4 was up regulated in hypertension, the expression of Myoz2 and Slc25a23 was down regulated. Conclusion: Cacna1d, Serpine1, Slc8a3, Trpc4, Myoz2 and Slc25a23 may be involved in the regulation of calcium metabolism pathways and play key roles in hypertension. These differentially.expressed calcium metabolism-related genes may serve as pr

外出农民返乡创业是缓解农村就业压力、提高农民收入和推动“打工经济”向“创业经济”转型的重要途径。本文使用双重差分法和全国县域面板数据,考察了返乡创业试点政策对农村居民收入的影响与机理。研究发现,该政策通过促进创业、推动第二、三产业发展以及吸引要素流入等途径,显著提高了试点地区的农村居民收入,且这种政策效应具有较好的包容性和农村偏向性。各地区的消费市场规模、金融效率、产业集聚程度和创业环境的发展差异,都会对返乡创业试点政策的农民增收效果产生门槛效应。各地区应不断加强对返乡农民的创业支持和政策引导,持续优化创业环境、加快非农产业发展、提高地区的要素吸引力并创造更多的创业就业机会,以提高农村居民收入和推动城乡均衡发展。
