Abstract:

Objective  To screen and identify  the hub genes  closely related to cardiac hypertrophy by using bioinformaticsmethod  and biological experiments.   Methods  The chip data related to cardiac hypertrophy in mice were downloaded from the Gene Expression Omnibus(GEO) database, and the GEO2R online tool was adopted to screen for differentially expressed genes; DAVID 6.7, String 11.0 and Cytoscape 3.7.0 softwares were used to analyze differentially expressed genes; Kunming mice were randomly divided into a normal saline group (n=6) and an angiotensin Ⅱ (Ang Ⅱ) group (n=6) to establish a cardiac hypertrophy model, the expression of  hub genes in Kunming mouse model of cardiac hypertrophy induced by AngⅡ was detected by Real-time PCR method .    Results  A total of 202 common differentially expressed genes and 12 hub genes were selected; the Real-time PCR result  demonstrated that decorin(Dcn), HADHA and heat shock protein(HSP)90αA1 were significantly down-regulated in the AngⅡ group.    Conclusion  The selected hub genes can influence the development of cardiac hypertrophy in Kunming mice through extracellular matrix and transforming growth factor β(TGF-β).
