  • The steady state behavior of Slug exhibits sensitivity to changes in the rate at which it is induced by β-catenin upon activation of the Wnt pathway. (biomedcentral.com)
  • In the presence of sufficient amount of Wnt ligand, E-cadherin levels are sensitive to the ratio of the rate of Slug activation via β-catenin to the IC 50 concentration of Slug necessary to inhibit E-cadherin production. (biomedcentral.com)
  • Firstly, loss of dGLYAT suppressed scrib depletion- or Egr overexpression-induced JNK pathway activation and invasive cell migration. (sdbonline.org)
  • In contrast, traditional models predict that the signal presentation from the source via free secretion and extracellular diffusion is a non-selective process. (biorxiv.org)
  • In addition, Wnt/β-catenin has emerged as a critical regulator of cancer stem cells (CSCs), which is considered one of the root causes of cancer recurrence and metastasis because of their heterogeneity and plasticity ( 13 ). (frontiersin.org)
