Summary
Chimeric ribonucleic acids (RNAs) arise from gene fusion or splicing. These chimeric RNAs impact prostate cancer progression and offer potential new biomarkers and therapeutic targets.
Area of Science:
- Molecular biology
- Genetics
- Oncology
Background:
- Chimeric RNAs are formed through gene fusion, trans-splicing, or cis-splicing between adjacent genes (cis-SAGe).
- These molecules play diverse roles in cellular processes and disease.
Purpose of the Study:
- To investigate the role of chimeric RNAs in prostate cancer (PCa) progression.
- To identify chimeric RNAs as potential biomarkers and therapeutic targets for PCa.
Main Methods:
- Analysis of gene fusion and splicing events.
- Characterization of chimeric RNA functions (lncRNA, circRNA, fusion protein coding).
- Assessment of chimeric RNA misregulation in PCa.
Main Results:
- Chimeric RNAs influence PCa progression through various mechanisms.
- They can act as long noncoding RNAs (lncRNAs) or circular RNAs (circRNAs).
- Chimeric RNAs can code for fusion proteins and misregulate parental genes.
Conclusions:
- Misregulated chimeric RNAs represent a novel class of molecules in PCa.
- These aberrant RNAs hold promise as biomarkers for PCa diagnosis and prognosis.
- Targeting chimeric RNAs could offer new therapeutic strategies for prostate cancer.

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

21.3K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

56.4K
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

8.6K
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...

01:23RNA Interference
26.0K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

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...
