Abstract:

Objective

To analyse the key differential expressed genes and regulatory signaling pathways between stroke and osteoporosis by bioinformatics methods.

Methods

The microarray data of stroke and osteoporosis genes were retrieved from the GEO database of the National Center for Biotechnology Information (NCBI), and the microarray samples were screened according to the inclusion criteria. The data were aggregated and were normalized before analysis by the R language and the GEO2R online tool to obtain differential expressed genes between patients and controls. Then, the Gene Ontology database, Kyoto Gene and Genome Database (KEGG), WikiPathways, Reactome database, gene/protein interaction retrieval tool, R language, Cytoscape analysis software and Metascape databases and analysis tools were used to perform differentially expressed gene analysis, functional annotation, and enrichment analysis.

Results

A total of 72 DEGs associated with both stroke and osteoporosis were screened out. GO analysis showed that the biological function of DEGs was mainly involved in the negative regulation of stem cell differentiation. KEGG, WikiPathways, Reactome and other databases show that DEGs is mainly enriched in cytokine signal transductions and other signaling pathways in the immune system. Ten key genes, SMARCA4, SMARCA2, SMC1A, MSL3, CBX5, NFKB2, HIRA, CASP1, VCP and CD86, were screened by protein interaction network.

Conclusion

The DEGs screened by bioinformatics technology, which related to the pathogenesis of stroke patients and osteoporosis, mainly involved in cytokine signaling in immune system, providing new research clues and directions for further exploring the correlation between the occurrence and development of the two and their molecular mechanism.
