Key Event Relationship Description
Beta-catenin activation, of which mechanism include the stabilization of the dephosphorylated beta-catenin and translocation of beta-catenin into the nucleus, induce the formation of beta-catenin-TCF complex and transcription of transcription factors such as Snail, Zeb and Twist (Clevers & Nusse, 2012) (Ahmad et al., 2012; Pearlman, Montes de Oca, Pal, & Afaq, 2017; Sohn et al., 2019; Yang et al., 2019).
EMT-related transcription factors including Snail, ZEB and Twist are up-regulated in cancer cells (Diaz, Vinas-Castells, & Garcia de Herreros, 2014). The transcription factors such as Snail, ZEB and Twist bind to E-cadherin (CDH1) promoter and inhibit the CDH1 transcription via the consensus E-boxes (5’-CACCTG-3’ or 5’-CAGGTG-3’), which leads to EMT (Diaz et al., 2014).
Evidence Supporting this KER
The treatment of human gastric cancer cells with INC280, which inhibits c-MET overexpressed in diffuse-type gastric cancer with poor prognosis, shows downregulation in beta-catenin and Snail expression,(Sohn et al., 2019).
The treatment with garcinol, a polyisoprenylated benzophenone derivative that is obtained from Garcinia indica extract, induced ZEB1 and ZEB2 down-regulation, increase in phosphorylated beta-catenin and decrease in nuclear beta-catenin in human breast cancer cells (Ahmad et al., 2012).
Sortilin, a member of the Vps10p sorting receptor family which is highly expressed in high-glade malignant glioma, positively regulates GSK-3beta/beta-catenin/Twist signaling pathway in glioblastoma (Yang et al., 2019).
The transcription factors such as Snail, Zeb and Twist inhibit the CDH1 expression through their binding towards the promoter of CDH1, which leads to inhibition of cell adhesion and EMT (Diaz et al., 2014)
Uncertainties and Inconsistencies
It is possible that the inhibition of ZEB1 and ZEB2 by garcinol treatment is caused by down-regulation of NFkappaB and Wnt/beta catenin signaling (Ahmad et al., 2012).
The EMT is induced different transcription factors other than Zeb, Twist and Snail, which includes E47 and KLF8 (Diaz et al., 2014).
Zeb, Twist and Snail may activate or inactivate different genes or molecules to induce phenomena related to EMT and other phenomena other than EMT (Li & Balazsi, 2018).
The treatment with AF38469, a sortilin inhibitor, in 0, 100, 200, 400, 800, and 1600 nM concentration inhibited beta-catenin and Twist expression dose-dependently in human glioblastoma cells (Yang et al., 2019).
Snail (SNAI1) mRNA is methylated and N6-methyladenosine (m6A) in its coding region (CDS) and 3’ untranslated region (3’UTR) are significantly enriched during EMT progression (Lin et al., 2019). The m6A enrichment fold of SNAI1 mRNA in EMT cells is about 2.3-fold greater than in control cells (Lin et al., 2019).
The treatment with 25 uM of garcinol for 48 hours induced increase in phosphorylated beta-catenin and decreased nuclear beta-catenin protein and ZEB1/ZEB2 mRNA in human breast cancer cells (Ahmad et al., 2012).
The treatment with AF38469, a sortilin inhibitor, for 0, 2, 4, 8, 16, or 24 hours shows that the expression of beta-catenin and Twist decrease in 8 hours followed by the subsequent decrease in 16 and 24 hours in human gliobastoma cells (Yang et al., 2019).
Snail (SNAI1) transfection for 48 hours induce the repression of E-cadherin (CDH1) protein expression (Lin et al., 2019).
SNAI1 mRNA in polysome is up-regulated in EMT-undergoing HeLa cells treated with 10 ng/ml of TGF-beta for 3 days compared with control cells (Lin et al., 2019).
Known modulating factors
The proto-oncogene MET regulates beta-catenin and Snail expression (Sohn et al., 2019).
The inhibition of GSK3beta by SB216763 induced expression of beta-catenin and Twist, as well as mesenchymal markers such as N-cadherin, vimentin and MMP9 (Yang et al., 2019).
The decrease in E-cadherin (CDH1), a cell adhesion molecule, is related to EMT (Diaz et al., 2014).
Methyltransferase-like 3 (METTL3) modulates methylation of Snail (SNAI1) mRNA and EMT (Lin et al., 2019).
Binding of beta-catenin to members of the TCF/LEF family transcription factors increase gene expression related to EMT such as Twist and decrease E-cadherin protein expression (Qualtrough, Rees, Speight, Williams, & Paraskeva, 2015).
Known Feedforward/Feedback loops influencing this KER
The inhibited expression of phosphorylated GSK3beta, beta-catenin and Twist by sortilin inhibition is reversed by GSK3beta inhibition. Furthermore, twist overexpression by lentivirus increased the inhibited expression of N-cadherin, MMP9 and vimentin and reverses the inhibitory effect of AF38469 on sortilin, which suggests that sortilin induces glioblastoma invasion mainly via GSK3beta/beta-catenin/Twist induced mesenchymal transition (Yang et al., 2019).
The inhibition of Hedgehog signaling pathway with cyclopamine reduces beta-catenin-TCF transcriptional activity, decreases the Twist expression, induces E-cadherin expression and inhibits EMT (Qualtrough et al., 2015).
