Summary
Vascular inflammation, driven by NF-κB signaling, contributes to atherosclerosis. MicroRNAs regulate this pathway, offering potential therapeutic targets for cardiovascular disease and aging.
Area of Science:
- Cardiovascular Biology
- Molecular Medicine
- Aging Research
Background:
- Cardiovascular diseases, including atherosclerosis, are major global health burdens.
- Atherosclerosis progression is linked to vascular inflammation and endothelial cell activation.
- The transcription factor NF-κB is central to endothelial inflammatory signaling, with enhanced activity during aging.
Purpose of the Study:
- To review the role of microRNAs in regulating vascular inflammation and NF-κB signaling.
- To explore the therapeutic potential of microRNA-based interventions for cardiovascular diseases.
- To discuss emerging roles of long noncoding RNAs and circulating microRNAs in vascular health.
Main Methods:
- Literature review of studies on microRNAs, NF-κB signaling, and vascular inflammation.
- Analysis of data from mouse models of vascular inflammation and atherosclerosis.
- Synthesis of current knowledge on noncoding RNA regulation in endothelial cells.
Main Results:
- Noncoding RNAs, especially microRNAs, significantly modulate the NF-κB signaling pathway in vascular inflammation.
- Dysregulation of these microRNAs is implicated in the pathogenesis of atherosclerosis.
- Aging exacerbates NF-κB activation, potentially mediated by altered noncoding RNA expression.
Conclusions:
- MicroRNAs are key regulators of vascular inflammation and NF-κB activity.
- Targeting microRNA pathways presents a promising therapeutic strategy for atherosclerosis and age-related cardiovascular disease.
- Further research into long noncoding RNAs and circulating microRNAs may reveal novel therapeutic avenues.

10.9K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

01:24Regulation of Angiogenesis and Blood Supply
4.0K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

01:31Transducer Mechanism: Nuclear Receptors
6.5K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

01:45Regulation of Nuclear Protein Sorting
3.5K
Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...

02:39lncRNA - Long Non-coding RNAs
10.2K
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...
