Summary
A novel long non-coding RNA, UGGT1-AS1, regulates gene expression and RNA editing. This discovery sheds light on UGGT1-AS1
Area of Science:
- Molecular Biology
- Epigenetics
- Cancer Biology
Background:
- Long non-coding RNAs (lncRNAs) are key regulators of gene expression.
- Natural antisense transcripts can form duplexes with sense transcripts, enabling RNA editing.
- A-to-I RNA editing influences splicing, gene products, and RNA stability, impacting cancer.
Purpose of the Study:
- To identify and characterize a novel natural antisense transcript, UGGT1-AS1.
- To investigate the role of UGGT1-AS1 in cell proliferation and UGGT1 transcript stability.
- To explore the potential link between UGGT1-AS1 and A-to-I RNA editing in cancer.
Main Methods:
- Identification and characterization of UGGT1-AS1.
- Analysis of cellular localization and sense partner interactions.
- RNA sequencing, RT-PCR, and Sanger sequencing to detect RNA editing events.
Main Results:
- UGGT1-AS1 was identified and characterized.
- UGGT1-AS1 influences cell proliferation and UGGT1 sense transcript stability.
- A-to-I RNA editing events in UGGT1 were identified and confirmed.
Conclusions:
- UGGT1-AS1 plays a regulatory role in gene expression and RNA stability.
- UGGT1-AS1 may trigger A-to-I RNA editing in its sense partner, UGGT1.
- The findings suggest UGGT1-AS1's involvement in RNA editing and cancer biology.

8.5K
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...

3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
