Insights

Epithelial splicing regulatory proteins (ESRPs) are vital for cell function and are implicated in cancer. Understanding ESRPs offers new avenues for cancer diagnostics and treatments.

Area of Science:

  • Oncology
  • Molecular Biology
  • RNA Biology

Background:

  • Cancer is a leading cause of global mortality, with complex pathogenesis.
  • Epithelial splicing regulatory proteins (ESRPs) regulate alternative splicing of messenger RNAs (mRNAs).
  • ESRP dysregulation is linked to cancer progression, but mechanisms are unclear.

Purpose of the Study:

  • To review the structure, function, and regulation of ESRPs.
  • To elucidate the role of ESRPs in cancer progression.
  • To highlight ESRPs as potential cancer biomarkers and therapeutic targets.

Main Methods:

  • Literature review of recent findings on ESRPs.
  • Analysis of ESRP structure, function, and regulatory mechanisms.
  • Examination of ESRP involvement in cancer pathogenesis.

Main Results:

  • ESRPs (ESRP1 and ESRP2) are RNA-binding proteins crucial for alternative splicing.
  • ESRP expression and activity are modulated by post-translational modifications and non-coding RNAs.
  • ESRP dysregulation is associated with various cancers, impacting progression.

Conclusions:

  • ESRPs play a significant role in cancer development and progression.
  • ESRPs hold promise as prognostic biomarkers for cancer patients.
  • Targeting ESRPs may lead to novel, individualized cancer therapeutics.

RNA Splicing01:32

RNA Splicing

Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

Alternative RNA Splicing02:18

Alternative RNA Splicing

Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Chromatin Structure Regulates pre-mRNA Processing02:41

Chromatin Structure Regulates pre-mRNA Processing

In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.

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.

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
