Insights

Epigenetic changes, specifically histone methylation (H3K27me3), are crucial in cancer. This review examines the role of JMJD3 and EZH2 in regulating these epigenetic marks and their impact on various cancer types.

Area of Science:

  • Oncology
  • Epigenetics
  • Molecular Biology

Background:

  • Cancer remains a leading global cause of mortality.
  • Epigenetic modifications, influenced by external and internal factors, play a significant role in cancer initiation and progression.
  • Histone modifications, particularly histone 3 lysine 27 trimethylation (H3K27me3), are frequently altered in various cancers.

Purpose of the Study:

  • This review focuses on the epigenetic mark H3K27me3 and its regulators.
  • The primary objective is to explore the role of Jumonji Domain-Containing Protein 3 (JMJD3) in cancer development.
  • To analyze the implications of JMJD3 and H3K27me3 dysregulation across diverse cancer types.

Main Methods:

  • Literature review of scientific studies on JMJD3, EZH2, and H3K27me3 in cancer.
  • Categorization of data based on cancer type to elucidate specific roles.
  • Synthesis of current knowledge on the interplay between epigenetic regulators and tumorigenesis.

Main Results:

  • H3K27me3 is a repressive epigenetic mark often dysregulated in cancer.
  • JMJD3 and Enhancer of zeste homolog 2 (EZH2) are key regulators of H3K27 methylation.
  • Deregulation of JMJD3 is implicated in the development of numerous cancers, including nervous system, prostate, blood, colorectal, breast, lung, liver, ovarian, and gastric cancers.

Conclusions:

  • JMJD3 and its associated epigenetic mark H3K27me3 are critical factors in cancer development.
  • Understanding the role of JMJD3 in H3K27 methylation offers potential therapeutic targets for cancer treatment.
  • Further research into JMJD3's function across different cancer types is warranted.

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...

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.

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

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...
