Summary
Mutations in the breast cancer susceptibility gene 2 (BRCA2) are linked to hereditary breast cancer and other tumors. This review covers BRCA2
Area of Science:
- Oncology
- Genetics
- Molecular Biology
Background:
- The breast cancer susceptibility gene 2 (BRCA2) is a primary genetic factor in hereditary breast cancer.
- BRCA2 mutations are increasingly recognized in diverse tumor types, including ovarian, pancreatic, thyroid, gastric, laryngeal, and prostate cancers.
Approach:
- This review synthesizes current research on the biological functions of the BRCA2 gene.
- It examines the specific role of BRCA2 mutations in the development and progression of various cancers.
Key Points:
- BRCA2 plays a crucial role in DNA repair mechanisms.
- Loss-of-function mutations in BRCA2 disrupt genomic stability, promoting tumorigenesis.
- Understanding BRCA2's function is vital for targeted cancer therapies.
Conclusions:
- BRCA2 mutations have significant implications beyond breast cancer, affecting multiple tumor types.
- Further research into BRCA2's role can inform personalized treatment strategies and improve patient outcomes.

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.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

9.1K
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.

02:38The Ras Gene
6.4K
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

02:21Cancers Originate from Somatic Mutations in a Single Cell
12.5K
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...

02:59Cancer Prevention
6.3K
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.
