Key Event Description


Epithelial-mesenchymal transition (EMT) is a phenomenon in which the cells transit from epithelial-like into mesenchymal-like phenotypes (S. Tanabe, 2017; Shihori Tanabe, Komatsu, Kazuhiko, Yokozaki, & Sasaki, 2015). In cancer, cells exhibiting EMT features contribute into the metastasis and drug resistance.

It is known that D-2-hydroxyglurate induces EMT(Guerra et al., 2017; Jia, Park, Jung, Levine, & Kaipparettu, 2018; Mishra et al., 2018; Sciacovelli & Frezza, 2017). D-2-hydroxyglurate, an inhibitor of Jumonji-family histone demethylase, increased the trimethylation of histone H3 lysine 4 (H3K4) in the promoter region of the ZEB1, followed by the induction of EMT (Colvin et al., 2016).

Wnt5a induces EMT and metastasis in non-small-cell lung cancer (Wang, Tang, Gong, Zhu, & Liu, 2017).

EMT is related to Wnt/beta-catenin signaling and important for cancer (S. Tanabe, Kawabata, Aoyagi, Yokozaki, & Sasaki, 2016)

TGFb induces EMT (Wendt, Smith, & Schiemann, 2010).

ZEB is one of the important transcription factors for EMT regulation (Zhang, Sun, & Ma, 2015).

SNAI1 (Snail) is an important transcription factor for cell differentiation and survival, and the phosphorylation and nuclear localization of Snail1 induced by Wnt signaling pathways are critical for the regulation of EMT (Kaufhold & Bonavida, 2014).

Transcription factors SNAI1 and TWIST1 induce EMT (Hodge, Cui, Gamble, & Guo, 2018) (Mani et al., 2008)

It is suggested that Sp1, a transcription factor involved in cell growth and metastasis, is induced by cytochrome P450 1B1 (CYP1B1), and promotes EMT, which leads to cell proliferation and metastasis (Kwon et al., 2016).

How It Is Measured or Detected


  • EMT can be detected by immunostaining with pro-surfactant protein-C (pro-SPC) and N-cadherin in idiopathic pulmonary fibrosis (IPF) lung in vivo (Kim et al., 2006).
  • TGFbeta induces EMT, which can be detected by immunostaining with vimentin in lung aloevela in vivo (Kim et al., 2006).

Domain of Applicability


  • Wnt5a expression leads to epithelial-mesenchymal transition (EMT) and metastasis in non-small-cell lung cancer in Homo sapiens (Wang et al., 2017).
  • WNT2 expression lead to EMT induction in Homo sapiens (Zhou et al., 2016).
  • EMT is induced in cancer and involved in cancer metastasis in Homo sapiens (Suarez-Carmona, Lesage, Cataldo, & Gilles, 2017) (Du & Shim, 2016).

GOLPH3 induces EMT (Sun et al., 2017).


LiCl induces EMT (Fang et al., 2018).


D-2-hydroxyglutarate induces EMT (Colvin et al., 2016).
