Insights

Opioid conditioning protects the heart by reducing injury and cell death. Non-coding RNAs are key players in this process, offering potential new treatments for cardiovascular disease (CVD).

Area of Science:

  • Cardiology
  • Molecular Biology
  • Pharmacology

Background:

  • Cardiovascular disease (CVD) is a leading cause of global mortality, often due to coronary artery disease (CAD) and myocardial infarction (MI).
  • Opioid conditioning demonstrates efficacy in mitigating myocardial ischemia-reperfusion injury (IRI) and cardiomyocyte death, highlighting its cardioprotective potential.
  • Understanding the molecular mechanisms of opioid-induced cardioprotection is crucial for developing novel therapeutic strategies for CVD.

Purpose of the Study:

  • To review the current knowledge on the role of non-coding RNAs (ncRNAs) in opioid signaling.
  • To explore the involvement of ncRNAs in opioid-induced cardioprotection.
  • To identify potential therapeutic targets within ncRNA pathways for CVD treatment.

Main Methods:

  • Literature review of experimental and computational studies on ncRNAs and opioid signaling.
  • Analysis of ncRNA modulation by opioid receptor activation.
  • Examination of ncRNA regulation of cardiac gene expression in the context of opioid-induced cardioprotection.

Main Results:

  • Non-coding RNAs (ncRNAs), including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), are critical regulators of cardiac gene expression.
  • Opioid receptor activation can induce specific ncRNAs, which in turn modulate opioid signaling pathways.
  • These ncRNA-mediated effects are implicated in the cardioprotective outcomes observed with opioid conditioning.

Conclusions:

  • Non-coding RNAs are integral to the mechanisms underlying opioid-induced cardioprotection.
  • Targeting ncRNAs offers a promising avenue for developing innovative treatments for cardiovascular diseases.
  • Further research into ncRNA-opioid interactions can advance therapeutic strategies for myocardial infarction and related conditions.

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

siRNA - Small Interfering RNAs02:30

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

Opioid Analgesics: Synthetic and Semisynthetic Opioids

Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

piRNA - Piwi-interacting RNAs

PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

Opioid Receptors: Overview01:22

Opioid Receptors: Overview

Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...
