Metastasis02:30

Metastasis

5.5K
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...

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

3.0K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Cancer Cell Migration through Invadopodia01:35

Cancer 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,...

Cell Migration01:19

Cell Migration

4.8K
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.

Chemotaxis and Direction of Cell Migration01:21

Chemotaxis and Direction of Cell Migration

3.4K
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...

Tumor Progression02:07

Tumor Progression

6.3K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Area of Science:

  • Oncology
  • Cell Biology
  • Cancer Research

Background:

  • Metastasis is a primary driver of cancer mortality, necessitating a deeper understanding of cancer cell dissemination.
  • Epithelial-mesenchymal plasticity (EMP) is a critical factor influencing cancer aggressiveness and the metastatic process.
  • Current knowledge of the mechanisms governing cancer cell aggressiveness and metastasis remains incomplete.

Purpose of the Study:

  • To propose a novel classification system for cancer cells.
  • To categorize cancer cells based on epithelial-mesenchymal plasticity (EMP).
  • To focus on the hysteresis of the epithelial-mesenchymal transition (EMT) and the hybrid epithelial/mesenchymal (E/M) phenotype.

Main Methods:

  • Extensive literature review on epithelial-mesenchymal plasticity (EMP).
  • Focused analysis on the hysteresis of the epithelial-mesenchymal transition (EMT).
  • Consideration of the hybrid epithelial/mesenchymal (E/M) phenotype.

Main Results:

  • A proposed classification system for cancer cells based on EMP.
  • Identification of four cancer cell types: irreversible hysteresis, weak hysteresis, strong hysteresis, and hybrid E/M phenotype.
  • These four types exhibit distinct biological characteristics, spreading patterns, and prognoses.

Conclusions:

  • The proposed classification provides insights into the heterogeneous behaviors of cancer cells.
  • This system has implications for understanding and potentially targeting cancer aggressiveness and metastasis.
  • Further research can leverage this classification to explore therapeutic strategies.
