Summary
Myosin-X (MYO10) knockdown reduces cell proliferation and migration. This study introduces new cell models for investigating MYO10's roles in cell adhesion and cytoskeletal dynamics.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- Myosin-X (MYO10) is an actin motor protein crucial for cellular functions.
- Its roles in cell proliferation, migration, and adhesion require further investigation.
Purpose of the Study:
- To investigate the cellular roles of Myosin-X (MYO10).
- To generate and characterize MYO10 knockdown (MYO10 KD) cell lines for future research.
Main Methods:
- Generation of MYO10 knockdown HeLa and COS7 cell lines using lentiviral shRNA.
- Assessment of cell proliferation, migration (wound assays), and cell spreading on laminin substrates.
- Analysis of cell morphology, including edge filopodia.
Main Results:
- MYO10 knockdown significantly reduced cell proliferation and impaired cell migration.
- Fewer edge filopodia were observed in MYO10 knockdown HeLa cells.
- MYO10 knockdown cells exhibited increased spreading on laminin, indicating altered integrin activation and cytoskeletal linkage.
Conclusions:
- Myosin-X (MYO10) plays a critical role in cell proliferation, adhesion, and migration.
- The developed MYO10 knockdown cell lines serve as a valuable model for studying MYO10 functions.

2.4K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

01:09Cell Migration
18.6K
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.

01:19Cell Migration
6.4K
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

01:18Role of Myosin in Cell Migration
3.2K
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....

6.5K
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....

4.5K
Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...
