Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

5.7K
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,...

Tumor Progression02:07

Tumor Progression

6.2K
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...

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

48.1K
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.

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

11.8K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Cancer-Critical Genes I: Proto-oncogenes01:33

Cancer-Critical Genes I: Proto-oncogenes

8.7K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Area of Science:

  • Oncology
  • Cell Biology
  • Cancer Metastasis Research

Background:

  • Metastasis is the primary cause of cancer mortality, driven by collective invasion.
  • Collective invasion relies on specialized "Leader Cells" that direct cell migration and tissue movement.
  • The full impact of leader cells in promoting metastasis is an evolving area of cancer research.

Purpose of the Study:

  • To review the expanded role of leader cells in cancer metastasis.
  • To detail leader cell plasticity, including the hybrid epithelial-mesenchymal transition (EMT) state.
  • To explore leader cells' involvement in therapeutic resistance and immune evasion.

Main Methods:

  • Literature review of existing research on leader cells in cancer metastasis.
  • Analysis of emerging evidence on leader cell phenotype and function.
  • Synthesis of findings on leader cells' roles in treatment resistance and immune evasion.

Main Results:

  • Leader cells exhibit phenotypical plasticity and a hybrid epithelial-mesenchymal transition (EMT) state.
  • These leader cells are crucial for collective invasion, enabling tumor spread.
  • Leader cells contribute to chemotherapeutic resistance and immune evasion in metastatic cancers.

Conclusions:

  • Leader cells play a critical, multifaceted role in cancer metastasis beyond traditional collective invasion.
  • Their unique characteristics, including EMT plasticity, drive treatment resistance and immune evasion.
  • Leader cells represent promising and diverse targets for developing novel anti-cancer therapies.
