RNA-seq03:21

RNA-seq

9.9K
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases. 
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Ribosome Profiling02:24

Ribosome Profiling

3.5K
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.
The technique...

Background:

  • Long-read RNA sequencing provides high-resolution insights into RNA modifications, structures, and protein interactions at the isoform level.
  • Analyzing these RNA features requires integration with genomic and transcriptomic annotations like open reading frames and splice junctions.

Purpose of the Study:

  • To develop a bioinformatics tool, R2Dtool, for integrating and analyzing RNA features within their genomic context at the isoform level.
  • To demonstrate R2Dtool's utility in expediting the analysis of epitranscriptomics data and facilitating the interpretation of alternative transcript isoforms.

Main Methods:

  • Development of R2Dtool, a bioinformatics software.
  • Integration of transcript-mapped RNA feature data with transcript and genome annotations.
  • Application of R2Dtool to epitranscriptomics data for isoform-resolved analysis.

Main Results:

  • R2Dtool enables isoform-resolved analytics and graphical representation of RNA features in their genomic context.
  • The tool successfully integrates and expedites RNA feature analysis, as demonstrated with epitranscriptomics data.
  • R2Dtool facilitates comprehensive analysis and interpretation of alternative transcript isoforms.

Conclusions:

  • R2Dtool is a valuable bioinformatics resource for researchers studying RNA modifications, structures, and functions.
