Summary
Adenomatous Polyposis Coli (APC) protein regulates cell migration by influencing both actin and microtubule cytoskeletons. This review proposes a model for how APC connects microtubule dynamics to actin nucleation, impacting cell motility.
Area of Science:
- Cell Biology
- Molecular Biology
- Cancer Research
Background:
- Adenomatous Polyposis Coli (APC) protein is a known tumor suppressor involved in Wnt signaling.
- APC is also a crucial cytoskeletal protein impacting cell migration.
- Mutations in APC are associated with colorectal cancer and neurological disorders.
Purpose of the Study:
- To review the known roles of APC in cell migration.
- To propose a model for APC's function in regulating cell motility.
- To elucidate the molecular mechanisms linking APC to cytoskeletal dynamics.
Main Methods:
- Literature review of existing studies on APC protein.
- Analysis of APC's interactions with actin and microtubule networks.
- Development of a conceptual model for APC-mediated cell migration.
Main Results:
- APC regulates both actin and microtubule cytoskeletons.
- APC acts as an intermediary connecting microtubule signals to actin nucleation.
- APC influences leading edge protrusion via Arp2/3 complex activation.
Conclusions:
- APC's cytoskeletal functions are critical for cell migration.
- APC integrates external signals through microtubules to modulate actin dynamics.
- Understanding APC's role in cell motility may offer insights into cancer and neurological diseases.

01:35Cancer Cell Migration through Invadopodia
2.4K
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

17.3K
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

00:50Anaphase Promoting Complex
3.0K
The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...

01:32Cytoskeletal Coordination in Cell Migration
4.9K
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...

01:31Mechanism of Lamellipodia Formation
2.8K
Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...

01:18Role of Myosin in Cell Migration
2.5K
Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common type in animal cells, which binds and cross-links actin filaments.
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction....
