Insights

Cancer cells hijack gene expression through altered messenger RNA (mRNA) stability and translation. Understanding these post-transcriptional changes, regulated by RNA-binding proteins (RBPs), is key to developing targeted cancer therapies.

Area of Science:

  • Molecular Biology
  • Cancer Biology
  • Genetics

Background:

  • Deregulation of gene expression is a fundamental characteristic of cancer cells.
  • Altered protein expression can confer growth, motility, and cell cycle advantages to cancer cells.
  • Post-transcriptional regulation of mRNA stability and translation is a critical mechanism influencing gene expression.

Purpose of the Study:

  • To review how alterations in mRNA regulatory elements, RNA-binding proteins (RBPs), and signaling pathways impact mRNA stability and translation in cancer.
  • To highlight the role of these post-transcriptional mechanisms in promoting tumorigenesis and cancer progression.
  • To underscore the potential for developing novel cancer therapies targeting mRNA modulation.

Main Methods:

  • Literature review of studies on post-transcriptional gene regulation in cancer.
  • Analysis of mechanisms controlling mRNA stability and translational efficiency.
  • Examination of the roles of RNA-binding proteins (RBPs) and regulatory sequences.

Main Results:

  • Alterations in mRNA stability and translation are frequently observed in cancer cells.
  • Dysregulation of RBPs and regulatory sequences affects mRNAs encoding key proteins like proto-oncogenes and cell cycle regulators.
  • These changes contribute significantly to tumor initiation and advancement.

Conclusions:

  • Post-transcriptional regulation plays a crucial role in cancer development and progression.
  • Targeting mRNA stability and translation presents a promising avenue for innovative cancer therapies.
  • Further research into these mechanisms can lead to the design of specific therapeutic strategies.

Epigenetic Regulation

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

Regulation of Expression Occurs at Multiple Steps

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

What is Gene Expression?

A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is comprised  of nucleotides and proteins are comprised of amino acids, a mediator is required to convert the information encoded in DNA into proteins. This mediator is the messenger RNA (mRNA). mRNA copies the blueprint from DNA by a process called transcription. In eukaryotes, transcription occurs in the nucleus by complementary base-pairing with the DNA template. The mRNA is then processed and...

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.

Regulation of Expression at Multiple Steps01:23

Regulation of Expression at Multiple Steps

The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the addition of a...
