RNA-seq

RNA-seq

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 Profiling

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.
The technique...

Purpose of the Study:

To evaluate long-read RNA-Seq for transcriptome analysis.
To address challenges in transcript isoform detection, quantification, and de novo transcript detection.
To establish a benchmark for current practices and guide future method development.

Main Methods:

Generated over 427 million long-read sequences from cDNA and direct RNA datasets.
Utilized data from human, mouse, and manatee species.
Applied diverse protocols and sequencing platforms.

Main Results:

Longer, accurate sequences yield more accurate transcripts compared to increased read depth.
Greater read depth improves quantification accuracy.
Reference-based tools performed best on well-annotated genomes.

Conclusions:
