Studies have shown that TGF‐β stimulates EndMT through the Smad2/3 signaling pathway, and this stimulation is essential for increasing the expression of cell‐adhesion‐suppressing transcription factors (TF), such as Snail, Twist, and Slug, which may be potential targets in CF (Medici, Potenta, & Kalluri, 2011). This evidence concerns the gene SNAI1 and cystic fibrosis.
