Insights

RNA-binding proteins (RBPs) are crucial for RNA metabolism and impact diseases like cancer. Understanding the RNA-RBP network offers new anti-cancer therapeutic strategies.

Area of Science:

  • Molecular Biology
  • Cancer Biology
  • RNA Metabolism

Background:

  • Recent advances highlight the complexity of cellular RNA metabolism.
  • RNA-binding proteins (RBPs) are key regulators of RNA processing, including splicing, transport, and translation.
  • Dysregulation of RBPs is linked to various diseases, notably cancer.

Purpose of the Study:

  • To review the emerging roles of RBPs in coordinating post-transcriptional RNA regulation.
  • To discuss how altered RBPs contribute to cancer-specific RNA alternative splicing.
  • To emphasize the potential of the RNA-RBP network as a source for novel anti-cancer targets.

Main Methods:

  • Literature review of recent advances in RNA biology and RBP function.
  • Analysis of the role of RBPs in post-transcriptional gene regulation.
  • Exploration of the connection between RBP dysregulation and cancer-related alternative splicing.

Main Results:

  • RBPs act as global coordinators of post-transcriptional RNA steps.
  • Altered RBPs are significant generators of cancer-associated RNA alternative splicing.
  • The RNA-RBP network is complex and integral to cellular RNA metabolism.

Conclusions:

  • Characterizing the RNA-RBP network is essential for a broader understanding of RNA metabolism.
  • Targeting cancer-specific RNA-RBP interactions presents promising avenues for novel anti-cancer therapies.

Types of RNA01:23

Types of RNA

Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...

Protein Networks02:26

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
