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...

RNA-seq03:21

RNA-seq

9.8K
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...

Area of Science:

  • Genomics
  • Transcriptomics
  • Epigenomics

Background:

  • Single-molecule, long-read sequencing (LRS) technologies from Oxford Nanopore and Pacific Biosciences have transformed biological research.
  • LRS offers direct detection of DNA modifications (e.g., methylation) and analysis of kilobase-spanning DNA sequences at the single-molecule level.

Purpose of the Study:

  • To review LRS-based experimental and computational strategies for characterizing chromatin states.
  • To highlight the advantages of LRS over short-read sequencing methods.
  • To demonstrate the integration of LRS methods for multi-omics studies investigating chromatin states and transcriptional dynamics.

Main Methods:

  • Discussion of LRS technologies and their applications in epigenomics.
  • Comparison of LRS with short-read sequencing approaches.
  • Integration strategies for multi-omics data using LRS.

Main Results:

  • LRS facilitates comprehensive epigenomic profiling by integrating DNA methylation, chromatin accessibility, transcription factor binding, and histone modification data.
  • LRS enables the detection of alternative, nascent, and translating transcripts.
  • LRS provides a powerful tool for analyzing chromatin states and their relationship with transcriptional dynamics.

Conclusions:

  • LRS technologies offer significant advantages for epigenomic research and transcriptomics.
  • Integrated LRS-based multi-omics studies are crucial for a holistic understanding of gene regulation and cellular function.
