Epigenetic Regulation

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

Epigenetic Regulation

3.2K
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

3.3K
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...

Master Transcription Regulators02:23

Master Transcription Regulators

7.3K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Ribosome Profiling02:24

Ribosome Profiling

3.7K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Area of Science:

  • Molecular Biology
  • Epigenetics
  • Oncology

Background:

  • N6-methyladenosine (m6A) is the most abundant internal modification in eukaryotic messenger RNAs (mRNAs).
  • m6A modification regulates gene expression post-transcriptionally.
  • YTH domain-containing proteins act as m6A readers, specifically recognizing and binding to m6A-modified mRNAs to control their fate.

Purpose of the Study:

  • To review the biological functions of YTH domain proteins in human cancers.
  • To elucidate the underlying mechanisms of YTH domain protein involvement in cancer.
  • To discuss the clinical implications and therapeutic potential of targeting m6A readers in oncology.

Main Methods:

  • Literature review of recent studies on m6A readers in cancer.
  • Analysis of the roles of YTH domain proteins in cancer initiation and development.
  • Examination of gene expression reprogramming mediated by dysregulated m6A readers.

Main Results:

  • YTH domain proteins are essential for the initiation and progression of various human cancers.
  • Dysregulation of m6A reader proteins leads to significant gene expression reprogramming.
  • m6A reader proteins influence cancer cell metabolism, proliferation, and metastasis.

Conclusions:

  • YTH domain proteins are critical regulators in cancer biology.
  • Targeting m6A reader proteins presents a promising strategy for novel cancer therapies.
  • Manipulation of m6A metabolism through targeted editors and readers offers new avenues for cancer treatment.
