Summary
Circular RNAs (circRNAs) are stable noncoding RNAs with vital roles in cellular processes. Their tissue specificity and stability make them promising biomarkers for diseases like cancer, but consistent data and scalable therapeutic development are needed.
Area of Science:
- Molecular Biology
- Genomics
- Biochemistry
Background:
- Circular RNAs (circRNAs) are a class of stable, noncoding RNAs.
- They regulate key cellular processes such as proliferation, apoptosis, and cell cycle progression.
- CircRNAs exhibit high tissue specificity and stability, making them potential disease biomarkers.
Purpose of the Study:
- To review the biological roles and potential applications of circRNAs.
- To highlight circRNAs as biomarkers for various diseases, including cancer and neurological disorders.
- To discuss challenges and future directions in circRNA research and therapeutic development.
Main Methods:
- Literature review of studies on circRNA function, expression, and disease association.
- Analysis of circRNA stability and tissue-specific expression patterns.
- Evaluation of circRNAs as diagnostic biomarkers and therapeutic agents.
Main Results:
- CircRNAs are implicated in regulating fundamental cellular processes.
- Differential expression of circRNAs is observed across numerous diseases.
- Blood circRNAs show potential as disease biomarkers, though consistency across studies is a challenge.
- CircRNAs offer advantages over mRNA for RNA therapeutics due to stability and lower immunogenicity.
Conclusions:
- CircRNAs are significant regulators of cellular functions and hold promise as disease biomarkers.
- Further research is required to elucidate their specific roles in disease pathways and establish reproducible diagnostic data.
- Development of efficient and scalable production systems is crucial for advancing circRNA-based therapeutics.

8.9K
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...

92.6K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

17.0K
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...

3.6K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

10.4K
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
