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). The gene discussed is TGFB1; the disease is cystic fibrosis.
