RNA-seq03:21

RNA-seq

11.6K
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

4.0K
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...

Area of Science:

  • Bioinformatics
  • Genomics
  • Molecular Biology

Background:

  • Next-generation sequencing (NGS) based small RNA analysis is crucial for understanding biological systems.
  • Existing tools often focus on specific small RNA types (e.g., microRNAs), limiting comprehensive analysis.
  • Identifying and quantifying the full spectrum of small RNAs, including circulating RNAs as potential biomarkers, remains a challenge.

Purpose of the Study:

  • To develop a comprehensive, modular, and stand-alone platform for identifying and quantifying diverse small RNA molecules from sequencing data.
  • To provide a solution for interrogating the complete small RNA'ome, enabling downstream data analysis.
  • To offer customizable RNA databases and sequence processing tools for basic small RNA analysis.

Main Methods:

  • Development of COMPSRA, a comprehensive modular stand-alone platform.
  • Integration of prebuilt, customizable standard RNA databases.
  • Incorporation of sequence processing tools for small RNA analysis.

Main Results:

  • COMPSRA identified a greater diversity and abundance of small RNA molecules compared to existing tools.
  • The platform demonstrated effective identification and quantification of small RNAs from serum samples.
  • Evaluation on human serum samples from healthy controls confirmed COMPSRA's performance.

Conclusions:

  • COMPSRA provides a comprehensive solution for small RNA sequencing data analysis.
  • The platform enhances the interrogation of the full small RNA'ome, surpassing limitations of current tools.
  • COMPSRA is a valuable, freely available resource for non-commercial research in small RNA biology.
