Researchers developed novel drug screening technologies targeting RNA regulation to control gene expression. These methods identified drug candidates currently in clinical trials for unmet medical needs, highlighting the potential of post-transcriptional control.
Area of Science:
- Molecular Biology
- Genetics
- Drug Discovery
Background:
- Post-transcriptional regulation significantly impacts gene expression through RNA interactions.
- This regulation offers numerous targets for small molecule drugs to modulate protein accumulation.
Purpose of the Study:
- To describe two drug screening technologies targeting post-transcriptional regulation of specific messenger RNAs (mRNAs).
- To illustrate the therapeutic potential of targeting post-transcriptional control for diseases with unmet needs.
Main Methods:
- Gene Expression Modulation by Small Molecules (GEMS) technology uses 5' and 3' untranslated regions (UTRs) to identify compounds reducing protein production.
- A second method uses nonsense-containing mRNAs to screen for compounds promoting therapeutic nonsense suppression.
Main Results:
- Both screening programs successfully identified drug candidates.
- These candidates are currently undergoing clinical testing for human diseases.
Conclusions:
- Targeting post-transcriptional control represents a promising therapeutic strategy.
- The developed technologies demonstrate significant potential for treating diseases with high unmet clinical needs.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
