Summary
Circular RNAs (circRNAs) are stable, non-coding RNA molecules formed by back-splicing. This review covers circRNA biogenesis and function, focusing on their role in the cardiovascular system.
Area of Science:
- Molecular Biology
- Genetics
- Biochemistry
Background:
- Circular RNAs (circRNAs) represent a novel class of non-coding RNA molecules.
- Generated via back-splicing, circRNAs exhibit enhanced stability compared to linear RNAs due to their closed structure.
- Thousands of circRNAs are expressed across mammalian tissues, with many showing disease-specific patterns.
Purpose of the Study:
- To review the current understanding of circRNA biogenesis and function.
- To highlight the specific relevance of circRNAs within the cardiovascular system.
Main Methods:
- Computational analysis of RNA sequencing data.
- Review of existing literature on circRNA biogenesis and function.
Main Results:
- circRNAs are protected from exonuclease degradation, leading to increased stability.
- circRNAs are widely expressed in mammalian tissues, including the cardiovascular system.
- Numerous circRNAs are implicated in disease-specific expression patterns.
Conclusions:
- Significant progress has been made in elucidating circRNA biogenesis and function.
- circRNAs play crucial roles in the cardiovascular system, warranting further investigation.

18.5K
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...

02:57piRNA - Piwi-interacting RNAs
7.6K
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...

02:39lncRNA - Long Non-coding RNAs
9.8K
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...

01:10Deformation in a Circular Shaft
887
One of the distinctive characteristics of circular shafts is their ability to maintain their cross-sectional integrity under torsion. In other words, each cross-section continues to exist as a flat, unaltered entity, simply rotating like a solid, rigid slab. To understand the distribution of shearing stress within such a shaft, consider a cylindrical section inside this circular shaft. This section has a length of L and a radius of R, with one end fixed. The radius of the cylindrical section is...
