Insights
Researchers identified novel blood biomarkers, BTNL8 and BLNK, for atherosclerosis diagnosis. This discovery offers potential for new, simpler diagnostic methods for this complex cardiovascular disease.
Area of Science:
- Biochemistry
- Genomics
- Cardiovascular Medicine
Background:
- Atherosclerosis is a complex arterial disease causing cardiovascular issues.
- Current diagnostic methods are invasive or indirect, lacking simple blood biomarkers.
- A need exists for accessible biochemical markers for atherosclerosis diagnosis.
Purpose of the Study:
- To identify novel blood biochemical markers for atherosclerosis.
- To analyze gene expression data for potential diagnostic targets.
- To validate candidate genes for clinical significance in atherosclerosis.
Main Methods:
- Analysis of three Gene Expression Omnibus (GEO) datasets.
- Identification of differentially expressed genes (DEGs) using Robustrankaggreg.
- Verification of critical genes using cell classification data.
Main Results:
- Screened 21 potential genes, identifying correlations for RPS4Y1, EIF1AY, and XIST.
- Determined the expression patterns of these genes in various cell types and whole blood.
- Identified BTNL8 and BLNK as genes with significant clinical relevance for atherosclerosis.
Conclusions:
- BTNL8 and BLNK show promise as diagnostic and evaluative markers for atherosclerosis.
- Findings contribute to understanding atherosclerosis's genetic underpinnings.
- This research may lead to new, non-invasive diagnostic approaches for cardiovascular disease.
Abstract:
Atherosclerosis is a multifaceted disease characterized by the formation and accumulation of plaques that attach to arteries and cause cardiovascular disease and vascular embolism. A range of diagnostic techniques, including selective coronary angiography, stress tests, computerized tomography, and nuclear scans, assess cardiovascular disease risk and treatment targets. However, there is currently no simple blood biochemical index or biological target for the diagnosis of atherosclerosis. Therefore, it is of interest to find a biochemical blood marker for atherosclerosis. Three datasets from the Gene Expression Omnibus (GEO) database were analyzed to obtain differentially expressed genes (DEG) and the results were integrated using the Robustrankaggreg algorithm. The genes considered more critical by the Robustrankaggreg algorithm were put into their own data set and the data set system with cell classification information for verification. Twenty-one possible genes were screened out. Interestingly, we found a good correlation between RPS4Y1, EIF1AY, and XIST. In addition, we know the general expression of these genes in different cell types and whole blood cells. In this study, we identified BTNL8 and BLNK as having good clinical significance. These results will contribute to the analysis of the underlying genes involved in the progression of atherosclerosis and provide insights for the discovery of new diagnostic and evaluation methods.
