Summary
Cellular invasion through extracellular matrix barriers is energy-intensive. Biosynthesis of lipids like fatty acids fuels the invasive migration of Caenorhabditis elegans anchor cells during development.
Area of Science:
- Cell Biology
- Developmental Biology
- Biochemistry
Background:
- Invasive cell migration is crucial for development and disease.
- This process requires significant cellular energy to overcome physical barriers like the extracellular matrix.
- Understanding the metabolic underpinnings of cell invasion is key to controlling cellular behaviors.
Purpose of the Study:
- To investigate the metabolic requirements for invasive cell migration.
- To identify key biosynthetic pathways supporting the energy demands of cell invasion.
- To elucidate the role of specific lipid biosynthesis in developmental cell migration.
Main Methods:
- Utilized Caenorhabditis elegans as a model organism.
- Focused on the anchor cell migration during embryonic development.
- Investigated the role of lipid biosynthesis pathways in facilitating basement membrane penetration.
Main Results:
- Demonstrated that biosynthesis of fatty acids, phospholipids, and isoprenoids is essential for invasive migration.
- Highlighted the critical role of these metabolic pathways in providing energy for breaching the basement membrane.
- Showcased the direct link between lipid production and the physical process of cell invasion.
Conclusions:
- Lipid biosynthesis is a critical driver of invasive cell migration.
- Metabolic processes, particularly lipid production, are integral to overcoming physical barriers during development.
- Targeting these biosynthetic pathways could offer strategies for modulating cell invasion.

16.9K
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.

01:35Cancer Cell Migration through Invadopodia
2.3K
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,...

Membrane fluidity is explained by the fluid mosaic model of the cell membrane, which describes the plasma membrane structure as a mosaic of components—including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character.
Mosaic nature of the membrane
The mosaic characteristic of the membrane helps the plasma membrane remain fluid. The integral proteins and lipids exist as separate but loosely-attached molecules in the membrane. The membrane is...

Biological membranes are more than just a barrier separating cell cytoplasm from the outside environment. They are highly dynamic and help maintain the integrity and physiological stability of the cells as well as membrane-bound organelles. Membranes also play vital roles in cell-to-cell and intracellular communication.
A large chunk of any biological membrane is composed of phospholipids. These lipids have a heterogeneous distribution across different subcellular organelles and even between...

01:18Role of Myosin in Cell Migration
2.2K
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....

01:28Types of Membrane Protrusions
2.8K
The protrusion of the cell surface is an initial step for several cellular processes, including cell migration, phagocytosis, and neurite outgrowth. These membrane protrusions are a result of cytoskeletal rearrangement. The most widely observed cell protrusions include lamellipodia, pseudopodia, filopodia, microvilli, invadopodia, and podosomes. These protrusions can be of two types — static or dynamic.
The microvilli, an example of stable protrusions, are finger-like projections...
