The purpose of our study was to identify molecular pathways altered during the pathogenesis of hypertrophic cardiomyopathy (HCM) based on data from the STRING protein-protein interaction (PPI) database and the REACTOME pathway database. Identification of differentially expressed genes (DEGs) was carried out, followed by construction of a targeted network and selection of hub genes in this network.
In this study, the in vivo interaction system of oligopeptide permease (Opp) proteins was analyzed, and a high expression system of inner membrane protein OppC was constructed by flexible usage of the green fluorescent protein (GFP). The Escherichia coli OppC gene, which encodes a transmembrane component of oligopeptide transporter, was cloned into different vectors. Recombinant plasmids were transformed into different E. coli strains, and the expression conditions were optimized.
