Cell Polarization by Rho Proteins01:21

Cell Polarization by Rho Proteins

2.8K
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 Invadopodia01:35

Cancer 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,...

Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

4.2K
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:

Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

2.8K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Role of Myosin in Cell Migration01:18

Role of Myosin in Cell Migration

2.4K
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....

Cell Motility through Blebbing01:16

Cell Motility through Blebbing

2.0K
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.

  • Oncology
  • Molecular Biology
  • Cell Biology

Background:

  • Metastasis is the primary cause of cancer mortality.
  • Cancer cell migration, particularly amoeboid migration, is crucial for metastasis.
  • Understanding the molecular mechanisms of amoeboid migration is vital for developing effective cancer treatments.

Purpose of the Study:

  • To identify molecular pathways regulating cancer cell amoeboid migration.
  • To investigate the role of MYADM in promoting cancer cell migration and metastasis.
  • To explore MYADM as a potential therapeutic target for inhibiting cancer metastasis.

Main Methods:

  • Identified MYADM as a protein enabling amoeboid migration in cancer cells.
  • Investigated MYADM's interaction with RhoGDI and its effect on RhoA signaling.
  • Analyzed MYADM's impact on chromatin accessibility and cytoskeleton dynamics.
  • Studied the consequences of MYADM loss on cancer cell metastasis and survival.

Main Results:

  • MYADM expression in cancer cells promotes amoeboid migration plasticity, enhancing metastasis and leading to poor patient outcomes.
  • MYADM facilitates cancer cell adhesion and migration, mimicking leukocyte trafficking.
  • MYADM activates RhoA-mediated leukocyte trafficking-associated genes (LTAG) enrichment, increasing invasiveness, membrane blebbing, and anoikis resistance.
  • MYADM modulates chromatin accessibility-regulatory genes, affecting cytoskeleton dynamics.
  • Loss of MYADM in cancer cells induces chromatin accessibility-driven cell death, inhibiting metastasis.

Conclusions:

  • MYADM is a key driver of cancer cell amoeboid migration and metastasis.
  • MYADM's function in cancer cells differs from its role in monocytes.
  • MYADM represents a promising therapeutic target for blocking cancer metastasis.
