TNC and asthma: It should be emphasized that only a part of the listed genes have been verified here as probable markers of asthma-driven fibrosis (Fn1, C3, C3ar1, Cyp2e1, Col4a1, and Col4a2); an investigation of the marker function of residuary genes (Thbs1, Ccr3, Ccl6, Ccl9, Tnc, and Itgb6) in pulmonary fibrosis is the subject of future studies.
