Screening Feature Genes of Venous Thromboembolism with DNA Microarray

Area of Science:

• Genomics
• Bioinformatics
• Molecular Biology

Background:

• Venous thromboembolism (VTE) is a significant health concern.
• Identifying molecular mechanisms underlying VTE is crucial for therapeutic advancements.

Purpose of the Study:

• To explore potential genes and pathways associated with VTE.
• To identify novel therapeutic targets for VTE treatment.

Main Methods:

• Downloaded and analyzed gene expression data (GSE19151) from the Gene Expression Omnibus (GEO) database.
• Employed bioinformatics methods to screen for differentially expressed genes (DEGs) and related pathways in VTE.
• Constructed gene interaction networks to identify key regulatory genes.

Main Results:

• Identified 115 differentially expressed genes (DEGs) in VTE, with 90 upregulated and 25 downregulated.
• Upregulated genes were enriched in ribosome and translation pathways; downregulated genes in cytoskeletal protein binding and non-membrane-bounded organelle pathways.
• MCL1, TP53, and RERE emerged as critical genes in the VTE interaction network, with ribosome and oxidative phosphorylation pathways being most significant.

Conclusions:

• Ribosome, translation, actin binding, and non-membrane-bounded organelle pathways are closely linked to VTE development.
• The genes MCL1, TP53, and RERE may play pivotal roles in the pathogenesis of VTE.
• These findings offer potential targets for developing novel VTE therapeutic strategies.
