CTNNAL1 and asthma: In our previous study, we found that the expression of catenin alpha-like 1 (CTNNAL1) is downregulated in asthma patients and in an ovalbumin-stressed asthmatic mouse model, but markedly increased in human bronchial epithelial cells (HBECs) in the lungs and at the edge of HBECs exposed to ozone stress [6–8].
