Tumor Progression02:07

Tumor Progression

6.8K
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-Critical Genes II: Tumor Suppressor Genes

8.5K
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...

Cancer

51.5K
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.

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

6.1K
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,...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.0K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

13.4K
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...

Background:

  • The CCN family of proteins (CCN1-6) are matricellular proteins involved in cell adhesion, proliferation, and migration.
  • Previous reviews in 2016 highlighted their roles in cancer, but recent advances necessitate an updated perspective.

Purpose of the Study:

  • To provide a comprehensive update on the CCN protein family's role in cancer pathogenesis and progression.
  • To detail the complex interactions of CCN proteins within the extracellular microenvironment and their intracellular functions.
  • To discuss the implications of CCN proteins in various cancer subtypes and their potential as therapeutic targets.

Main Methods:

  • Literature review and synthesis of recent research findings on CCN proteins in cancer.
  • Harmonization of CCN nomenclature for clarity and comparison.
  • Discussion of CCN protein involvement across different cancer subtypes.

Main Results:

  • Significant progress has been made in understanding how CCN1-6 proteins contribute to both the promotion and inhibition of cancer.
  • CCN proteins interact with extracellular matrix components, cell surface receptors, and regulate gene transcription.
  • New insights reveal a greater involvement and importance of CCN proteins in multiple facets of cancer biology.

Conclusions:

  • The CCN protein family is critically involved in various aspects of cancer, from initiation to progression.
