Insights

RNA-binding proteins (RBPs) rapidly control gene expression, acting as key regulators in cancer development. Understanding RBPs and their targets offers new therapeutic strategies for cancer treatment.

Area of Science:

  • Molecular Biology
  • Cancer Biology
  • Genetics

Background:

  • Posttranscriptional gene regulation allows rapid cellular adaptation.
  • RNA-binding proteins (RBPs) are crucial regulators of mRNA processing and translation.
  • Aberrant RBP expression is linked to cancer development.

Purpose of the Study:

  • To describe mechanisms of RBP influence on oncogene expression.
  • To highlight the role of RBPs in posttranscriptional control of cancer.
  • To identify RBPs as potential cancer therapeutic targets.

Main Methods:

  • Review of mechanisms by which RBPs regulate gene expression.
  • Focus on specific examples of RBPs affecting oncogenes.
  • Analysis of the evolution of RNA-binding domains.

Main Results:

  • RBPs form complex networks with mRNA targets, influencing tumorigenesis.
  • RBPs demonstrate versatility in posttranscriptional control of cancer.
  • Identification of RBPs, their targets, and mechanisms provides therapeutic insights.

Conclusions:

  • RBPs are fundamental players in tumor development.
  • Targeting RBPs and their networks offers novel therapeutic avenues for cancer.

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...

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.

RNA Stability01:53

RNA Stability

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
