Insights

Ribonucleases (enzymes that degrade RNA) have diverse biological roles, impacting cell growth and immunity. Understanding their dual effects is key to developing targeted cancer therapies.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Immunology

Background:

  • Ribonucleases (RNases) are enzymes critical for RNA degradation.
  • They are involved in essential cellular processes like protein synthesis, epigenetic regulation, cell proliferation, and apoptosis.
  • RNases also function as antimicrobial, antiviral, and immune defense factors.

Purpose of the Study:

  • To explore the diverse and sometimes opposing biological effects of ribonucleases.
  • To investigate the potential of leveraging RNase functions for targeted cancer treatment strategies.

Main Methods:

  • Biochemical analysis of RNase properties.
  • Biological assays to assess effects on cell proliferation, apoptosis, and tumor development.
  • Evaluation of RNase inhibitor effects.

Main Results:

  • Ribonucleases exhibit varied biological activities, with most inhibiting cell proliferation and tumor growth, while some stimulate vascular growth and tumor development.
  • RNase inhibitors demonstrate opposing effects.
  • The distinct biological actions of RNases are not solely dependent on their biochemical properties.

Conclusions:

  • Ribonucleases possess dual roles in cellular processes and disease modulation.
  • Targeted application of RNase functions and their inhibitors offers potential for novel anti-cancer therapeutic strategies.
  • Further research into the specific mechanisms of RNase action can refine tumor growth modulation approaches.

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...

The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

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.

Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Ribozymes02:47

Ribozymes

The term ribozyme is used for RNA that can act as an enzyme. Ribozymes are mainly found in selected viruses, bacteria, plant organelles, and lower eukaryotes. Ribozymes were first discovered in 1982 when Tom Cech’s laboratory observed Group I introns acting as enzymes. This was shortly followed by the discovery of another ribozyme, Ribonulcease P, by Sid Altman’s laboratory. Both Cech and Altman received the Nobel Prize in chemistry in 1989 for their work on ribozymes.
