Common drugs like opioids and cannabinoids can alter DNA methylation and histone patterns. These epigenetic changes, influenced by drug interactions, may affect health and be heritable, necessitating new screening tools.
Area of Science:
- Pharmacology
- Epigenetics
- Drug Discovery
Background:
- Growing evidence suggests common medications can induce epigenetic alterations.
- These changes involve modifications to DNA methylation and histone conformations.
- Drug interactions with epigenetic enzymes and DNA repair mechanisms are implicated.
Purpose of the Study:
- To investigate the potential of common drugs to induce epigenetic modifications.
- To highlight the role of epigenetic alterations in drug effects and resistance.
- To underscore the need for advanced epigenetic screening tools.
Main Methods:
- Review of existing evidence on drug-induced epigenetic effects.
- Computational prediction of drug interactions with histone deacetylase (HDAC).
- Experimental verification of predicted HDAC interactions.
Main Results:
- Common drugs (opioids, cannabinoids, valproic acid, cytostatics) can alter epigenetic patterns.
- Computational analysis predicted significant potential for drug interaction with HDAC.
- Experimental validation confirmed HDAC interaction for a high-probability compound.
- Epigenetic effects contribute to drug efficacy, toxicity, and resistance.
Conclusions:
- Drug-induced epigenetic modifications are a significant factor in pharmacology.
- Epigenetic alterations can lead to diverse phenotypes and influence drug resistance.
- There is an urgent need for cost-effective epigenetic screening tools due to potential heritability.

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...
