Summary
Circular RNAs (circRNAs) show promise as cancer biomarkers due to their stability and presence in bodily fluids. Further research is needed to apply these noninvasive biomarkers for early cancer detection.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- Circular RNAs (circRNAs) are novel RNA molecules with diverse biological functions.
- Emerging evidence links circRNAs to cancer development and progression.
- Cancer-specific and tissue-specific circRNAs have been identified using high-throughput sequencing.
Purpose of the Study:
- To review the potential of circRNAs as biomarkers in cancer.
- To discuss the characteristics of circRNAs that make them suitable for biomarker applications.
- To explore the current understanding of circRNA functions and their clinical relevance in oncology.
Main Methods:
- Literature review of studies identifying and characterizing circRNAs in various cancers.
- Analysis of circRNA properties, including stability, abundance, and presence in biofluids.
- Examination of published data on the predictive and prognostic significance of circRNAs.
Main Results:
- CircRNAs possess ideal biomarker properties: conserved, abundant, and stable in plasma, saliva, and urine.
- Numerous circRNAs demonstrate predictive and prognostic value in cancer.
- Functional roles for certain circRNAs in cancer pathogenesis are being elucidated.
Conclusions:
- CircRNAs hold significant potential as noninvasive biomarkers for early cancer detection.
- Further investigation is required to translate circRNA research into clinical applications.
- CircRNAs represent a promising frontier in cancer diagnostics and therapeutics.

9.5K
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...

01:03Rous Sarcoma Virus (RSV) and Cancer
5.9K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

02:23Abnormal Proliferation
5.0K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

02:38The Ras Gene
6.8K
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
