Scientists have in a recent study identified 1350 differentially regulated genes directly responsible for development of COPD. A research recently carried out by a team of scientists at the Departments of Respiratory and Critical Care, The Fifth Affiliated Hospital of Guangxi Medical University, and The First People’s Hospital of Nanning, China, showed that these genes were significantly enriched in immune-related biological functions among the GSE47460 and GSE151052 datasets that they analysed. Of these, 11 feature genes which emerged from analysis of a subset of GSE47460 data could be potential diagnostic markers and therapeutic targets for COPD.
