Summary
Dietary ribonucleosides offer health benefits, promoting gut health and iron absorption. Certain ribonucleosides show potential as anticancer agents by inducing apoptosis in human cells.
Area of Science:
- Biochemistry
- Molecular Biology
- Nutritional Science
Background:
- Ribonucleosides, found naturally and modified chemically, exhibit significant bioactive properties.
- Dietary ribonucleosides are primarily consumed as nucleoproteins, undergoing digestion into monomeric forms.
- These compounds play roles in enhancing gut development and increasing iron absorption.
Purpose of the Study:
- To explore the diverse bioactive effects of naturally occurring and modified ribonucleosides.
- To investigate the potential of ribonucleosides as anticancerogenic compounds.
- To assess the therapeutic and pharmaceutical applications of indigenous ribonucleosides.
Main Methods:
- Cytochemical studies using human cells to observe ribonucleoside effects.
- Analysis of in vivo concentrations and target sites of ribonucleosides.
- Review of existing applications of chemically modified ribonucleosides.
Main Results:
- Ribonucleosides can enhance gut growth, maturation, and iron absorption.
- Several ribonucleosides demonstrated the ability to induce apoptosis in human cells, indicating anticancer potential.
- Modified ribonucleosides are utilized as biomarkers for cancer and in pharmaceutical treatments.
Conclusions:
- Dietary ribonucleosides, even at suboptimal food concentrations, can reach effective levels in vivo, potentially targeting intestinal cells for apoptosis.
- Ribonucleosides hold promise for applications in functional foods and pharmaceutical preparations.
- Further research is needed to fully evaluate the therapeutic efficacy of indigenous ribonucleosides.

01:23Types 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.

01:22Antiviral Nucleoside Inhibitors
Antiviral Nucleoside InhibitorsAntiviral nucleoside inhibitors are structural analogs of natural nucleosides that interfere with viral DNA or RNA synthesis. These compounds selectively target viral polymerases due to their resemblance to host nucleosides, thereby disrupting viral genome replication.Mechanism of Acyclovir ActionAcyclovir is a guanosine analog with a three-carbon acyclic side chain. It selectively targets herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2),...
02:47Ribozymes
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.

02:24Ribosome Profiling
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
