Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

2.2K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Chemotaxis and Direction of Cell Migration01:21

Chemotaxis and Direction of Cell Migration

3.7K
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...

Metastasis02:30

Metastasis

5.8K
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...

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

2.5K
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,...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

7.0K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

The Tumor Microenvironment02:17

The Tumor Microenvironment

6.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Main Methods:

  • Systematic literature review of studies published from 2000 onwards.
  • Analysis of data on CCR7 expression in different types of malignant tumors.
  • Evaluation of the correlation between CCR7 expression and cancer cell migration patterns.

Main Results:

  • CCR7 expression in malignant tumors has diverse effects on cell migration.
  • CCR7 can direct cancer cells to lymph nodes, skin, or the central nervous system.
  • In specific tumor types, CCR7 may exhibit a protective role against cancer progression.

Conclusions:

  • CCR7 plays context-dependent roles in cancer pathophysiology.
  • Further research is needed to elucidate the mechanisms regulating CCR7's dual role in cancer.
  • Understanding these mechanisms could lead to improved therapeutic strategies for CCR7-positive cancers.
