Insights

Nuclear receptors regulate cell growth and differentiation. Aberrant DNA methylation silences these genes in human cancers, contributing to tumor development and progression.

Area of Science:

  • Molecular Biology
  • Epigenetics
  • Cancer Biology

Background:

  • Nuclear receptors are crucial for basic biological processes like cell growth, differentiation, and apoptosis.
  • Dysregulation of nuclear receptors is implicated in human malignancies, affecting tumor development and progression.
  • While genetic alterations are known, epigenetic silencing via DNA methylation is an emerging mechanism for nuclear receptor gene downregulation in cancer.

Purpose of the Study:

  • To review the role of DNA methylation in silencing nuclear receptor genes.
  • To explore the involvement of epigenetic silencing of nuclear receptors in human malignancies.

Main Methods:

  • Literature review focusing on epigenetic mechanisms and nuclear receptor gene regulation.
  • Analysis of studies investigating DNA methylation patterns in cancer.

Main Results:

  • Aberrant DNA methylation is a significant mechanism for silencing nuclear receptor genes in tumors.
  • Epigenetic silencing modifies the expression of key genes during carcinogenesis.
  • This silencing contributes to the development and progression of human malignancies.

Conclusions:

  • DNA methylation plays a critical role in the aberrant silencing of nuclear receptor genes in human cancers.
  • Epigenetic modifications represent a key pathway through which nuclear receptor function is disrupted in malignancies.
  • Understanding these epigenetic mechanisms is vital for comprehending cancer development.

Epigenetic Regulation01:46

Epigenetic Regulation

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
Epigenetic Regulation01:37

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Transducer Mechanism: Nuclear Receptors01:31

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
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...
Co-activators and Co-repressors02:04

Co-activators and Co-repressors

Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...
Mutagenicity and Carcinogenicity01:25

Mutagenicity and Carcinogenicity

Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...
