Summary
This study identifies long non-coding RNAs (lncRNAs) associated with cystic vestibular schwannoma (cVS), a challenging brain tumor subtype. These lncRNAs may offer new biomarkers for diagnosing and managing cVS.
Area of Science:
- Neuro-oncology
- Molecular Biology
- Genomics
Background:
- Vestibular schwannoma (VS) is a common brain tumor, with cystic variants (cVS) exhibiting aggressive behavior and poor surgical outcomes.
- The molecular underpinnings of cVS pathogenesis and its aggressive nature are not well understood.
- Long non-coding RNAs (lncRNAs) are increasingly recognized for their roles in gene regulation and potential as diagnostic biomarkers.
Purpose of the Study:
- To identify and characterize differentially expressed lncRNAs in cystic vestibular schwannoma (cVS) compared to solid VS (sVS).
- To explore the potential of these lncRNAs as biomarkers for cVS diagnosis and management.
- To investigate the correlation between dysregulated lncRNAs and protein-coding genes in cVS.
Main Methods:
- Whole transcriptome RNA sequencing was performed on patient-derived samples of cVS and sVS.
- Bioinformatic analysis identified differentially expressed lncRNAs and protein-coding genes (PCGs).
- Quantitative reverse transcription PCR (qRT-PCR) was used to validate the expression levels of selected lncRNAs.
Main Results:
- The study identified 65 differentially expressed lncRNAs and 308 PCGs between cVS and sVS.
- Eight key lncRNAs were selected based on their significant correlation with numerous PCGs.
- Validation confirmed the upregulation of PCA3 and ADIRF-AS1, and downregulation of EGFLAM-AS1 in cVS.
Conclusions:
- lncRNAs are significantly dysregulated in cVS and are prevalent in this disease.
- The identified lncRNAs likely play critical roles in regulating signaling pathways involved in cVS pathogenesis.
- These findings suggest that cVS-associated lncRNAs hold promise for future biomarker development.

Ribosome Profiling
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

lncRNA - Long Non-coding RNAs
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 (lncRNA)...
Leaky Scanning
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 stands for...
