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...

RACE - Rapid Amplification of cDNA Ends

RACE - Rapid Amplification of cDNA Ends

Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific...

Background:

RNA sequencing (RNA-seq) is a powerful tool for analyzing gene expression.
Accurate transcript reconstruction and expression quantification are crucial for understanding cellular function.
Numerous computational methods exist, but their performance varies.

Purpose of the Study:

To evaluate the performance of various computational methods for RNA-seq data analysis.
To identify limitations in current RNA-seq analysis pipelines for transcript reconstruction and expression quantification.

Main Methods:

Assessed 25 protocol variants from 14 independent computational methods.
Focused on exon identification, transcript reconstruction, and expression-level quantification.
Utilized RNA-seq data from complex eukaryotic genomes.

Main Results:

Most methods successfully identified discrete transcript components.
Assembling complete isoform structures remained a significant challenge.
Expression-level estimates showed wide variation across different methods.
Genome complexity limited transcript recall and splice product discrimination.

Conclusions:

Current RNA-seq analysis methods struggle with complete isoform assembly and accurate expression quantification.
Higher eukaryotic genome complexity poses inherent limitations for RNA-seq data analysis.
Further development is needed to overcome these challenges in transcript analysis.
