Insights

Metastasis, the spread of cancer cells, causes most cancer deaths. Understanding how cancer cells spread and form secondary tumors is key to developing new therapies.

Area of Science:

  • Oncology
  • Cell Biology
  • Developmental Biology

Background:

  • Most cancer fatalities result from metastasis, not primary tumors.
  • Cancer cell invasion involves activating developmental programs.
  • Metastasis requires interactions between cancer cells, the tumor microenvironment, and target organs.

Purpose of the Study:

  • To elucidate the mechanisms of cancer metastasis.
  • To understand the role of the tumor microenvironment in metastasis.
  • To identify factors contributing to the formation of premetastatic niches.

Main Methods:

  • Analysis of cancer cell invasion pathways.
  • Investigation of developmental program induction in cancer cells.
  • Study of tumor microenvironment modifications during metastasis.
  • Research on the formation of premetastatic niches in target organs.

Main Results:

  • Cancer cells invade tissues by mimicking developmental processes.
  • Specific target organs are colonized by cancer cells based on their origin.
  • A premetastatic niche forms in target organs, attracting cancer cells.
  • Metastasis involves complex crosstalk between cancer cells and their surroundings.

Conclusions:

  • Understanding cancer cell metastasis mechanisms is crucial for patient care.
  • Targeting metastasis pathways offers potential for innovative cancer therapies.
  • Further research into the premetastatic niche could yield new therapeutic strategies.

Metastasis02:30

Metastasis

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

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, invadopodia can...
The Tumor Microenvironment02:17

The Tumor Microenvironment

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...

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
