MUC5AC and asthma: Among the transcripts that were increased after HDM-challenge, most markedly induced were those for the chloride channel calcium activated member 3 (clca3), Eosinophil associated ribonuclease A family 11 (ear11) and Mucin-5AC (Muc5ac), each of these has been previously identified as potential biomarkers in asthma (Laprise et al., 2004; Woodruff et al., 2007; Park et al., 2008; Louten et al., 2012).
