Metastasis02:30

Metastasis

6.3K
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 Stem Cells and Tumor Maintenance

5.8K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Cancer02:18

Cancer

53.3K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

The Tumor Microenvironment02:17

The Tumor Microenvironment

7.5K
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...

Area of Science:

  • Oncology
  • Cell Biology
  • Cancer Research

Background:

  • Circulating tumor cells (CTCs) and CTC clusters (tumor microemboli) are found in biological fluids.
  • Single CTC research advanced understanding of tumor invasion, metastasis, and heterogeneity.
  • CTC clusters are increasingly recognized for their critical role in cancer pathophysiology and metastasis.

Purpose of the Study:

  • To review recent insights into the origin and dissemination of CTC clusters.
  • To explore the molecular mechanisms behind CTC cluster survival and metastatic potential.
  • To discuss the clinical relevance of CTC clusters as prognostic biomarkers.

Main Methods:

  • Literature review of recent advances in CTC cluster research.
  • Analysis of molecular packages enabling CTC cluster survival.
  • Examination of the molecular basis for enhanced metastatic potential of CTC clusters.

Main Results:

  • CTC clusters demonstrate superior resistance to cell death compared to single CTCs.
  • The molecular composition of CTC clusters contributes to their increased metastatic capacity.
  • Evidence suggests CTC clusters possess significant prognostic value.

Conclusions:

  • CTC clusters are critical players in cancer metastasis, surpassing single CTCs in metastatic potential.
  • Understanding CTC cluster biogenesis and molecular characteristics is vital for cancer research.
  • Future research should focus on leveraging CTC clusters for clinical applications and improved cancer monitoring.
