Insights

The phosphatase and tensin homolog (PTEN/MMAC1) gene, a newly found tumor suppressor, does not appear to be a significant factor in hereditary breast cancer development. Further research is needed, but initial screening found no relevant mutations in affected families.

Area of Science:

  • Oncology
  • Genetics
  • Molecular Biology

Background:

  • Hereditary breast cancer is a significant health concern.
  • Tumor suppressor genes play a crucial role in cancer prevention.
  • The PTEN/MMAC1 gene was recently identified and its role in cancer is under investigation.

Purpose of the Study:

  • To investigate the potential role of the PTEN/MMAC1 gene in hereditary breast cancer.
  • To screen for mutations in the PTEN/MMAC1 gene in families with a history of breast cancer.

Main Methods:

  • DNA screening of 10 families with hereditary breast cancer.
  • Direct sequencing of the PTEN/MMAC1 gene.

Main Results:

  • No relevant mutations in the PTEN/MMAC1 gene were identified in the screened families.
  • The study did not find evidence linking PTEN/MMAC1 alterations to hereditary breast cancer in this cohort.

Conclusions:

  • PTEN/MMAC1 does not appear to play a significant role in the genesis of hereditary breast cancer.
  • Further investigations are warranted to definitively exclude PTEN/MMAC1 involvement.

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

Loss of Tumor Suppressor Gene Functions

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...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

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...

Cancer-Critical Genes II: Tumor Suppressor Genes

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...

The Retinoblastoma Gene

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,...
Mismatch Repair01:20

Mismatch Repair

Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...
