Summary
MicroRNAs (miRNAs) are crucial regulators of metabolism in heart failure (HF). This review explores their role in metabolic changes, as biomarkers, and potential therapeutic targets for cardiovascular disease.
Area of Science:
- Molecular Biology
- Cardiovascular Medicine
- Biochemistry
Background:
- Heart failure (HF) is a condition where the heart cannot pump enough blood to meet the body's energy needs.
- MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression post-transcriptionally and are increasingly recognized for their role in cardiovascular diseases.
- Emerging evidence links miRNAs to the regulation of key metabolic pathways essential for maintaining energy balance.
Purpose of the Study:
- To review the mechanistic role of miRNAs in regulating metabolic functions within the context of heart failure.
- To discuss the implications of miRNAs in metabolic alterations observed in HF.
- To explore the potential of miRNA profiles as novel biomarkers for HF and summarize therapeutic strategies involving miRNAs in heart disease.
Main Methods:
- Literature review focusing on recent discoveries.
- Analysis of mechanistic studies on miRNA regulation of metabolic pathways in HF.
- Synthesis of research on miRNA biomarkers and therapeutic applications in cardiovascular disease.
Main Results:
- miRNAs play a significant role in regulating central metabolic pathways critical for energy homeostasis in HF.
- Specific miRNAs are implicated in the metabolic rearrangements characteristic of heart failure progression.
- miRNA profiles show promise as potential biomarkers for HF diagnosis and prognosis.
Conclusions:
- miRNAs are key regulators of metabolism in heart failure, influencing metabolic rearrangements.
- miRNA profiling represents a promising avenue for novel HF biomarker development.
- miRNA-based therapeutics offer potential new strategies for treating heart disease.

1.4K
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

24.5K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

1.2K
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

02:39lncRNA - Long Non-coding RNAs
10.1K
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...
