Insights

This study introduces a 3D assay to screen for cancer cell invasion regulators. Researchers used this method to investigate how Rho GTPases impact prostate cancer cell morphology and invasion in 3D Matrigel.

Area of Science:

  • Cell Biology
  • Cancer Research
  • Biochemistry

Background:

  • Rho GTPases are key regulators of cytoskeleton dynamics and cell motility.
  • Dysregulation of Rho GTPases is implicated in cancer progression and metastasis.
  • Investigating cancer cell invasion is crucial for understanding tumor metastasis.

Purpose of the Study:

  • To describe a 3D-based morphology assay for medium-throughput screening of cancer cell invasion regulators.
  • To investigate the role of Rho GTPases in prostate cancer cell morphology and invasion using the developed assay.

Main Methods:

  • Development of a 3D-based morphology assay using Matrigel.
  • Application of RNA interference (RNAi) to target Rho GTPases.
  • Microscopy-based screening to analyze cancer cell morphology and invasion in 3D.

Main Results:

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:

Cell Polarization by Rho Proteins01:21

Cell Polarization by Rho Proteins

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,...

Cancer 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,...

Cell Migration

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.

Cell Migration

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.

Role of Myosin in Cell Migration

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....
