Summary
Circular RNAs (circRNAs) are stable RNA molecules implicated in cancer development. Further research into circRNA-tumor interactions offers potential for early diagnosis and novel cancer therapies.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- Circular RNAs (circRNAs) represent a novel class of RNA molecules.
- Next-generation sequencing (NGS) technologies, particularly RNA-seq, have identified over 30,000 circRNAs.
- CircRNAs exhibit greater stability compared to linear RNAs due to their unique structure.
Purpose of the Study:
- To investigate the significant roles of circRNAs in cancer development (carcinogenesis).
- To explore the mechanisms underlying the interactions between circRNAs and tumors.
- To highlight the potential of circRNAs as biomarkers and therapeutic targets in oncology.
Main Methods:
- Utilizing next-generation sequencing (NGS) and RNA-sequencing (RNA-seq) to identify and quantify circRNAs.
- Analyzing the correlation between circRNA expression and patient clinical characteristics.
- Investigating circRNA functions in malignant phenotypes such as cell cycle, apoptosis, invasion, and metastasis.
Main Results:
- Over 30,000 circRNAs have been discovered using advanced sequencing technologies.
- CircRNA expression levels are associated with clinical features of cancer patients.
- CircRNAs influence key cancer processes including cell cycle regulation, apoptosis, angiogenesis, invasion, and metastasis, acting as RNA sponges or through translation.
Conclusions:
- CircRNAs play critical roles in the carcinogenesis and progression of various cancers.
- Understanding circRNA-tumor interactions is crucial for advancing cancer research.
- CircRNAs hold significant promise as molecular markers for early diagnosis, therapeutic evaluation, prognosis prediction, and as targets for gene therapy in cancer treatment.

01:03Rous Sarcoma Virus (RSV) and Cancer
6.5K
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.

02:38The Ras Gene
7.4K
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.

02:55The Nucleolus
10.6K
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,...

02:23Abnormal Proliferation
5.3K
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...

01:51Mechanisms of Retrovirus-induced Cancers
7.1K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

02:39lncRNA - Long Non-coding RNAs
10.1K
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...
