Summary
Long non-coding RNAs (lncRNAs) regulate cell functions. Sprouty4-Intron 1 (SPRY4-IT1) is a lncRNA overexpressed in many cancers, driving tumor progression and metastasis.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- Long non-coding RNAs (lncRNAs) are RNA molecules longer than 200 nucleotides, not translated into proteins.
- lncRNAs play critical roles in diverse cellular processes like proliferation, differentiation, cell death, and metastasis.
- SPRY4-IT1 is a lncRNA frequently overexpressed in various cancer types and associated with clinicopathological features.
Purpose of the Study:
- To review the characteristics of Sprouty4-Intron 1 (SPRY4-IT1).
- To elucidate the biological functions and molecular mechanisms of SPRY4-IT1 in cancer development and progression.
Main Methods:
- Literature review of studies on SPRY4-IT1.
- Analysis of SPRY4-IT1 expression patterns in various cancers.
- Examination of SPRY4-IT1's role in tumor progression and metastasis.
Main Results:
- SPRY4-IT1 is dysregulated in multiple cancers, including melanoma, breast, lung, gastric, colon, and liver cancers.
- Amplification of SPRY4-IT1 correlates with distinct clinicopathological features in cancer patients.
- SPRY4-IT1 significantly contributes to tumor progression and metastasis.
Conclusions:
- SPRY4-IT1 is a key player in cancer development and progression.
- Understanding SPRY4-IT1's molecular mechanisms is crucial for cancer therapy.
- Further research is needed to fully unravel SPRY4-IT1's role in oncogenesis.

10.0K
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...

01:32RNA Splicing
61.0K
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...

13.6K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

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.

02:18Alternative RNA Splicing
25.4K
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...
