Expressed in mast and T cells/inducible T cell tyrosine kinase (Emt/Itk), a Tec family protein tyrosine kinase, is critical for the development and activation of T lymphocytes. The mechanism through which Emt/Itk mediates its effector functions is poorly understood. In this study, we show that the Emt/Itk Src homology 2 (SH2) domain is critical for the transphosphorylation and activation of Emt...

Epithelial-mesenchymal transition (EMT) programmes provide cancer cells with invasive and survival capacities that might favour metastatic dissemination. Whilst signalling cascades triggering EMT have been extensively studied, the impact of EMT on the crosstalk between tumour cells and the tumour microenvironment remains elusive. We aimed to identify EMT-regulated soluble factors that facilitat...

Epithelial-mesenchymal transition (EMT) is a complex process by which cells acquire invasive properties that enable escape from the primary tumor. Complete EMT, however, is not required for metastasis: circulating tumor cells exhibit hybrid epithelial-mesenchymal states, and genetic perturbations promoting partial EMT induce metastasis in vivo. An open question is whether and to what extent int...

Metastasis of carcinoma involves migration of tumor cells to distant organs and initiate secondary tumors. Migration requires a complete or partial Epithelial-to-Mesenchymal Transition (EMT), and tumor-initiation requires cells possessing stemness. Epithelial cells (E) undergoing a complete EMT to become mesenchymal (M) have been suggested to be more likely to possess stemness. However, recent ...

Epithelial-mesenchymal transition (EMT) is a reversible and dynamic process hypothesized to be co-opted by carcinoma during invasion and metastasis. Yet, there is still no quantitative measure to assess the interplay between EMT and cancer progression. Here, we derived a method for universal EMT scoring from cancer-specific transcriptomic EMT signatures of ovarian, breast, bladder, lung, colore...

Epithelial-mesenchymal transition (EMT), as a crucial process in embryonic development and cancer metastasis, has been investigated extensively. However, how to quantify the global stability and transition dynamics for EMT under fluctuations remains to be elucidated. Starting from a core EMT genetic circuit composed of three key proteins or microRNAs (microRNA-200, ZEB and SNAIL), we uncovered ...

Objectives: This study aimed at adapting and examining the applicability of the Teach-Model-Coach-Review model of the enhanced milieu teaching (EMT) approach for improving Iranian mothers’ language strategies while interacting with their toddlers with expressive language delay. Methods: In a single-subject multiple-baseline across-behavior study, the mothers of 3 toddlers with expressive langu...

Gastrulation is a developmental process to generate the mesoderm and endoderm from the ectoderm, of which the epithelial to mesenchymal transition (EMT) is generally considered to be a critical component. Due to increasing evidence for the involvement of EMT in cancer biology, a renewed interest is seen in using in vivo models, such as gastrulation, for studying molecular mechanisms underlying ...

MicroRNAs (miRNAs) have been implied to play crucial roles for epithelial-to-mesenchymal transition (EMT) of non-small-cell lung cancer cells (NSCLC cells). Here we found that the expression of miR-149, downregulated in lung cancer, was inversely correlated with invasive capability and the EMT phenotype of NSCLC cells. miR-149 inhibited EMT in NSCLC cells. Furthermore, we demonstrated that miR-...
