By using microarray datasets for asthma and AR obtained from the Gene Expression Omnibus (GEO) database established by the National Center for Biotechnology Information (https://www.ncbi.nlm.nih.gov/geo/), Wang et al. [66] performed transcriptomic analyses which showed that CST1 was the only upregulated factor in patients with AR and asthma. This evidence concerns the gene CST1 and asthma.
