Summary
This study identifies long noncoding RNAs (lncRNAs) in the large yellow croaker fish. Researchers cataloged thousands of novel lncRNAs, with many specifically found in the spleen, suggesting roles in immune response.
Area of Science:
- Marine Biology
- Genomics
- Molecular Biology
Background:
- Long noncoding RNAs (lncRNAs) are crucial regulatory molecules in eukaryotes.
- Limited information exists on lncRNA expression and function in the large yellow croaker (Larimichthys crocea).
- Previous studies focused on protein-coding genes in this species.
Purpose of the Study:
- To create a comprehensive catalog of lncRNAs in the large yellow croaker.
- To investigate the tissue-specific expression patterns of lncRNAs.
- To identify potential immune-related lncRNAs in the spleen.
Main Methods:
- Integration of multiple RNA-sequencing datasets from various tissues (egg, muscle, liver, spleen).
- Bioinformatic analysis to reconstruct and identify high-confidence lncRNA transcripts.
- Comparative analysis of lncRNA expression profiles across different tissues.
Main Results:
- A total of 48,953 high-confidence lncRNA transcripts were identified across 38,017 loci.
- Thousands of novel lncRNA loci were discovered, expanding the known transcriptome.
- Most identified lncRNAs exhibited tissue-specific expression patterns.
- 210 lncRNAs were specifically enriched in the spleen, indicating potential immune functions.
Conclusions:
- This study provides the first systematic identification of lncRNAs in the large yellow croaker.
- The identified lncRNAs offer valuable resources for future genomic and functional studies in this species.
- Spleen-specific lncRNAs may play significant roles in the fish's immune response.

lncRNA - Long Non-coding RNAs
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...

Ribosome Profiling
4.3K
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.

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...
