Dlx‐2 has also been shown to be involved in TGF‐β and Wnt‐induced EMT in cancers.34 Also, HOXD3 supports the progression of lung cancer to a certain extent through TGF‐β‐induced EMT.17 Among the HOX proteins, TGF‐β1 induction of EMT in CRC cells was correlated with a significant rise in expression of HOXD9. This evidence concerns the gene HOXD3 and lung cancer.
