Cancer-Critical Genes I: Proto-oncogenes

11.9K
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 Prevention

8.7K
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...

Cancers Originate from Somatic Mutations in a Single Cell

15.5K
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...

Area of Science:

  • Genetics and Molecular Biology
  • Oncology
  • Medical Genetics

Background:

  • Genetic mutations, particularly in BRCA1 and BRCA2 genes, significantly increase susceptibility to breast and ovarian cancers.
  • Understanding these genetic predispositions is crucial for early detection and risk management.

Purpose of the Study:

  • To offer a foundational understanding of genetics.
  • To specifically address mutations in BRCA1 and BRCA2 genes related to hereditary breast and ovarian cancer (HBOC) susceptibility.

Main Methods:

  • A comprehensive review of existing research and review articles was conducted.
  • Information was also gathered from reputable government internet resources.

Main Results:

  • Advances in molecular biology facilitate proactive healthcare, enabling prediction of certain cancers.
  • Prevention strategies can be implemented to substantially lower cancer development risk.

Conclusions:

  • The evolving knowledge of genetics promises personalized cancer treatments and recurrence predictions.
  • Genetics will transform healthcare, requiring nurses to identify genetic links, educate families, and facilitate genetic counseling.
