|January 11, 2013
Summary
Cancer cell migration and metastasis depend on actin cytoskeleton regulation by actin binding proteins. This review explores how these proteins control cell structures and their aberrant expression during cancer progression.
Area of Science:
- Cell Biology
- Molecular Oncology
- Biochemistry
Background:
- Cancer metastasis involves cellular motility, driven by cytoskeletal rearrangements.
- Actin filaments form key cellular structures like lamella, lamellipodia, filopodia, and invadopodia.
- Actin binding proteins (ABPs) are crucial regulators of actin dynamics and cellular structure.
Purpose of the Study:
- To review the role of ABPs in regulating actin-based cellular structures involved in cancer cell migration.
- To explore the regulation of ABP expression during carcinogenesis.
- To highlight metastatic cell-initiated mechanisms driving aberrant ABP expression.
Main Methods:
- Literature review focusing on actin binding proteins and cancer metastasis.
- Analysis of mechanisms regulating ABP expression in cancer.
- Discussion of actin remodeling principles by ABPs.
Main Results:
- ABPs are central to controlling the geometry of cellular protrusions essential for invasion.
- Aberrant expression of ABPs is a hallmark of cancer progression.
- Metastatic cells employ novel strategies to induce abnormal ABP expression.
Conclusions:
- Understanding ABP regulation is critical for targeting cancer metastasis.
- ABPs represent promising therapeutic targets for inhibiting cancer cell migration and invasion.
- Further research into ABP expression mechanisms can reveal new anti-metastatic strategies.

01:11Formation of Higher-order Actin Filaments
The polymerization of G-actin monomers into filamentous F-actin is a multi-step process. Once the F-actins are formed, they can bundle together in different arrangements to form higher-order networks and regulate cellular functions. Common examples include the formation of lamellipodia and filopodia at the cell's leading edge by actin reorganization in a migrating cell. The microvilli on the brush border epithelial cells are also formed through the F-actin network.

01:13Actin Polymerization and Cell Motility
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.
Actin cytoskeleton dynamics can produce pushing, pulling, and resistance forces that help the cell to migrate.

02:30Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

01:35Cancer Cell Migration through Invadopodia
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, invadopodia can...
01:13Cytoskeletal Accessory Proteins
The cytoskeleton is an essential cell component that plays several structural and functional roles. However, the filaments that make up the cytoskeleton cannot function independently and depend on the accessory or ancillary proteins to effectively carry out their function. Accessory proteins associate with cytoskeletal filaments and their monomers, aiding filament formation and function. They also help in the cross-communication among cytoskeletal filaments. Cytoskeletal accessory proteins are...
01:56Structural Protein Function
Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to form...
