Summary
This study identified 94 differentially expressed circular RNAs (circRNAs) in rotator cuff tendinopathy, revealing potential therapeutic targets for improved treatment and prevention strategies.
Area of Science:
- Biochemistry
- Molecular Biology
- Genomics
Background:
- Rotator cuff tendinopathy is a common debilitating condition.
- Understanding the molecular mechanisms underlying tendinopathy is crucial for developing effective treatments.
Purpose of the Study:
- To identify differentially expressed circular RNAs (circRNAs) in rotator cuff tendinopathy.
- To elucidate the potential molecular mechanisms involving parental genes of these circRNAs.
Main Methods:
- RNA sequencing was performed on supraspinatus tendon samples from patients with rotator cuff tendinopathy and healthy controls.
- Bioinformatic analyses included Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and competing endogenous RNA (ceRNA) network construction.
Main Results:
- 94 differentially expressed circRNAs were identified (31 up-regulated, 63 down-regulated).
- GO analysis indicated enrichment in cyclic adenosine monophosphate (cAMP) response.
- KEGG analysis highlighted pathways such as extracellular matrix-receptor interaction and nuclear factor κB signaling.
Conclusions:
- This study identified novel circRNAs associated with rotator cuff tendinopathy.
- These findings offer potential therapeutic targets for the treatment and prevention of rotator cuff tendinopathy.

Leaky Scanning
5.5K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

The Nucleolus
10.1K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

Muscles that Move the Arm
4.4K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

RNA Structure
6.6K
The basic structure of RNA consists of a string of ribonucleotides attached by phosphodiester bonds. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.

There are three main types of ribonucleic acid (RNA) involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). All three...

Regulation of the Unfolded Protein Response
2.9K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

Types of RNA
8.6K
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
