Metastasis02:30

Metastasis

5.6K
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 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,...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

4.9K
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...

Cancer

48.6K
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.

Area of Science:

  • Oncology
  • Cancer Biology
  • Metastasis Research

Background:

  • Epithelial cancers are well-studied models for tumor spread.
  • Recent findings reveal distinct dissemination patterns in non-epithelial cancers.
  • Understanding these differences is crucial for effective cancer treatment.

Purpose of the Study:

  • To review current knowledge on non-epithelial tumor dissemination.
  • To highlight key differences compared to epithelial cancers.
  • To identify potential therapeutic strategies against disseminating non-epithelial cancers.

Main Methods:

  • Literature review of recent developments in melanoma, glioma, and sarcoma research.
  • Analysis of developmental process reactivation in cancer progression.
  • Examination of non-genetic mechanisms driving tumor spread.

Main Results:

  • Non-epithelial cancers exhibit unique dissemination strategies.
  • Reactivation of developmental processes is a key factor in their spread.
  • Non-genetic mechanisms play a significant role in tumor dissemination.

Conclusions:

  • Defining core principles of non-epithelial cancer dissemination can reveal vulnerabilities.
  • This knowledge may lead to improved therapeutic approaches for metastatic cancers.
  • Further research is needed to address remaining challenges and emerging questions.
