Summary
Long noncoding RNAs can act as oncogenes or tumor suppressors. A study shows PICSAR promotes skin cancer by activating ERK signaling, suggesting it as a potential diagnostic marker and therapeutic target.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Long noncoding RNAs (lncRNAs) are increasingly recognized for their roles in cancer, potentially acting as oncogenes or tumor suppressors.
- Cutaneous squamous cell carcinoma (cSCC) is a common skin cancer with significant public health implications.
Purpose of the Study:
- To investigate the role of the long noncoding RNA PICSAR in the development of cutaneous squamous cell carcinoma.
- To explore PICSAR's potential as a diagnostic marker and therapeutic target for cSCC.
Main Methods:
- The study utilized molecular biology techniques to analyze PICSAR expression and function in cSCC.
- Experimental models were employed to assess the impact of PICSAR on tumor growth and signaling pathways.
Main Results:
- Piipponen et al. provide evidence that PICSAR promotes cSCC development.
- PICSAR facilitates cSCC progression through the activation of extracellular signal-regulated kinase (ERK) signaling.
- Specific inhibition of PICSAR was found to suppress tumor growth in experimental models.
Conclusions:
- The long noncoding RNA PICSAR plays a crucial role in promoting cutaneous squamous cell carcinoma.
- PICSAR's involvement in ERK signaling activation highlights its oncogenic potential in cSCC.
- Targeting PICSAR may offer a promising strategy for cSCC diagnosis and treatment.

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...

13.9K
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...

02:23Abnormal Proliferation
5.4K
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...

01:32RNA Splicing
61.2K
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...

6.6K
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.
