CCN2 and asthma: Studies in other systems have reported that CTGF induction by TGF‐β is regulated through interactions of transcription factors with promoter elements directly upstream of the promoter start site.24, 25, 26, 27 In this study, we investigated the mechanisms that enhance TGF‐β induction of CTGF release from A‐ASM cells and the potential links to airway remodelling in asthma.
