Summary
We developed a single-cell platform to study cell migration patterns. This revealed how STAT3
Area of Science:
- Cellular Biology
- Biophysics
- Biotechnology
Background:
- Cell migration is crucial for development and disease, involving diverse patterns.
- Understanding the molecular basis of migration plasticity is limited.
- Existing tools hinder the study of spontaneous migration in single cells.
Purpose of the Study:
- To develop a micro/nanotechnology-enabled platform for single-cell migration analysis.
- To investigate the role of STAT3 regionalization in migration patterns.
- To explore the dynamic regulation of amoeboid-mesenchymal transitions.
Main Methods:
- Development of a micro/nanotechnology-based single-cell analytical platform.
- Coherent monitoring of spontaneous migratory patterns and signaling molecules.
- Bioinformatic analysis to identify downstream regulators.
Main Results:
- STAT3 regionalization (nuclear vs. cytoplasmic) dictates migration patterns (amoeboid vs. mesenchymal).
- JAK2 multisite phosphorylation antagonistically regulates STAT3 distribution.
- A reversible amoeboid-mesenchymal transition is triggered by JAK2-STAT3 dynamics.
- Bioinformatics identified a potential downstream regulator of nucleocytoplasmic STAT3.
Conclusions:
- The developed platform enables advanced single-cell migration research.
- STAT3 localization is a key regulator of cell migration modes.
- JAK2-STAT3 interactions drive reversible migration plasticity.
- Findings offer insights into tumor metastasis and progression mechanisms.

01:20The JAK-STAT Signaling Pathway
8.8K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

01:32Cytoskeletal Coordination in Cell Migration
4.7K
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker...

01:21Cell Polarization by Rho Proteins
2.7K
Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...

01:19Interactions Between Signaling Pathways
6.3K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
