Insights

Hyperparathyroidism-jaw tumor syndrome is caused by mutations in the HRPT2 gene, affecting the parafibromin protein. This review covers recent genetic and protein research on parafibromin and its functions.

Area of Science:

  • Genetics
  • Molecular Biology
  • Oncology

Background:

  • Hyperparathyroidism-jaw tumor (HPT-JT) syndrome is a rare genetic disorder.
  • It is characterized by the development of multiple tumors, including parathyroid adenomas and ossifying fibromas of the jaw.
  • The syndrome arises from inactivating mutations in the HRPT2 tumor suppressor gene.

Purpose of the Study:

  • To review recent advancements in the genetic and protein studies of parafibromin.
  • To examine the biological functions of parafibromin.

Main Methods:

  • Literature review of genetic studies.
  • Analysis of protein studies.
  • Examination of functional assays related to parafibromin.

Main Results:

  • Inactivating mutations in HRPT2 gene lead to HPT-JT syndrome.
  • HRPT2 gene encodes the parafibromin protein.
  • Recent studies have elucidated parafibromin's role in cellular processes.

Conclusions:

  • Understanding parafibromin's function is crucial for HPT-JT syndrome research.
  • Further investigation into parafibromin's biological roles may reveal therapeutic targets.

The Retinoblastoma Gene01:20

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,...

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...

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...

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...
