Cancer-Critical Genes I: Proto-oncogenes

10.7K
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.

Adaptive Mechanisms in Cancer Cells

6.7K
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,...

What is Cancer?

13.4K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of...

Loss of Tumor Suppressor Gene Functions

5.6K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Cancer Prevention02:59

Cancer Prevention

7.5K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
Some...

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Genetics

Background:

  • Capicua (CIC) is a conserved transcriptional repressor implicated in various human cancers.
  • CIC function is modulated by mitogen-activated protein kinase (MAPK) signaling and genetic alterations.
  • CIC dysregulation is linked to specific cancer subtypes and promotes tumor progression and metastasis.

Purpose of the Study:

  • To review the differential regulation of CIC in cancer.
  • To explore the mechanisms linking CIC dysregulation to subtype-specific cancer phenotypes.
  • To propose novel therapeutic strategies for CIC-altered cancers.

Main Methods:

  • Literature review of CIC's role in cancer.
  • Analysis of CIC's transcriptional control of effector genes.
  • Examination of functional and genetic regulatory mechanisms of CIC.

Main Results:

  • CIC's differential regulation through MAPK signaling or genetic alteration is key in specific cancer subtypes.
  • CIC directly controls effector genes, driving tumor progression and metastasis.
  • Convergent downstream transcriptional nodes are critical for CIC-driven oncogenesis.

Conclusions:

  • Understanding CIC's subtype-specific regulation is crucial for targeted cancer therapies.
  • Therapeutic strategies targeting CIC-altered cancers can be developed based on its regulatory mechanisms.
  • CIC represents a promising therapeutic target in oncology.
