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; W. Yang et al., 2019).
Evidence Collection Strategy
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 (W. Yang et al., 2019).
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).
Known modulating factors
The treatment with AF38469, a sortilin inhibitor, in 0, 100, 200, 400, 800, and 1600 nM concentration inhibited beta-catenin and Twist expression dose-depenently in human glioblastoma cells (W. Yang et al., 2019).
The treatment with 25 mM 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 (W. Yang et al., 2019).
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 (W. Yang et al., 2019).
