Insights

Nuclear SET domain containing proteins (NSD) are epigenetic regulators involved in cancer. Their role in oncogenesis may involve a switch between H3K36 methylation and H3K27 methylation marks.

Area of Science:

  • Epigenetics
  • Molecular Biology
  • Cancer Research

Background:

  • Nuclear SET domain containing (NSD) proteins are epigenetic regulators.
  • NSD proteins methylate histone H3 at lysine 36 (H3K36), depositing mono- and dimethyl marks.
  • H3K36 methylation is crucial for gene expression, splicing, and DNA repair.

Purpose of the Study:

  • To explore the oncogenic role of NSD proteins.
  • To elucidate the mechanism of NSD protein involvement in cancer.
  • To investigate the interplay between H3K36 methylation and H3K27 methylation in NSD-mediated oncogenesis.

Main Methods:

  • Review of recent findings on NSD proteins.
  • Analysis of epigenetic regulatory mechanisms.
  • Examination of histone modification patterns (H3K36Me and H3K27Me).

Main Results:

  • NSD proteins are implicated in various diseases and cancers.
  • The precise mechanisms of NSD action remain largely unknown.
  • A dysregulated switch between H3K36Me and H3K27Me is proposed to contribute to NSD protein oncogenic potential.

Conclusions:

  • NSD proteins play a significant role in cancer development.
  • Understanding the H3K36Me/H3K27Me switch is key to deciphering NSD's oncogenic functions.
  • Further research into NSD proteins could reveal novel therapeutic targets for cancer.

Cancer-Critical Genes I: Proto-oncogenes

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.

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...
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,...
The Ras Gene02:38

The Ras Gene

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.
