Insights

Cancer cells exhibit altered DNA methylation patterns, with specific genes silenced and global hypomethylation. Understanding DNA methylation machinery is key to developing new anticancer drugs targeting these processes.

Area of Science:

  • Epigenetics
  • Cancer Biology
  • Molecular Oncology

Background:

  • DNA methylation patterns are significantly altered in cancer cells compared to normal cells.
  • Aberrant methylation, including regional hypermethylation and global hypomethylation, impacts gene expression critical for cancer progression.
  • The DNA methylation machinery involves DNA methyltransferases, regulatory proteins, chromatin modifiers, and demethylases.

Purpose of the Study:

  • To review the critical roles of DNA methyltransferases and demethylases in tumorigenesis.
  • To explore the pharmacological and therapeutic implications of targeting the DNA methylation machinery in cancer treatment.

Main Methods:

  • Literature review of existing studies on DNA methylation in cancer.
  • Analysis of data on the function of DNA methylation machinery components.
  • Examination of in vitro, in vivo, and clinical trial data regarding pharmacological interventions.

Main Results:

  • Cancer cells display distinct DNA methylation profiles, including silencing of tumor suppressor genes and global hypomethylation.
  • The DNA methylation machinery is a complex network of enzymes and proteins.
  • Pharmacological targeting of DNA methylation machinery components shows promise in inhibiting cancer growth.

Conclusions:

  • DNA methylation plays a crucial role in cancer development and progression.
  • Targeting DNA methylation machinery offers a potential therapeutic strategy for cancer treatment.
  • Further research into the specific functions of DNA methylation machinery is essential for designing effective anticancer agents.

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.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Phase II Reactions: Methylation Reactions01:17

Phase II Reactions: Methylation Reactions

Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
