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...

Sanger Sequencing

Sanger Sequencing

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Computational Biology

Background:

Mapping sequencing reads to a reference genome is crucial for analyzing allele effects.
Using a single reference sequence can introduce bias due to genetic distances.
Existing methods using modified references have limitations like reduced mapping ratios and mapping shifts.

Purpose of the Study:

To propose a novel and generic multi-alignment pipeline to address biases in sequence analysis.
To improve read mapping ratios and the accuracy of determining genomic origins.
To provide a better method for assessing differential expression compared to single-reference approaches.

Main Methods:

Developed a multi-alignment pipeline integrating genomic variations from founders into separate reference sequences.
Performed alignments to each integrated reference sequence.
Merged aligned reads and annotated their genomic origins.

Main Results:

The multi-alignment pipeline rescued more reads compared to the single-reference pipeline.
Demonstrated a higher percentage of reads with assigned origins.
Showcased reduced bias associated with single common reference sequences.

Conclusions:

The proposed multi-alignment pipeline effectively diminishes bias in high-throughput sequencing data analysis.
It enhances read mapping efficiency and provides more accurate genomic origin information.
This method offers a superior approach for assessing differential expression in complex genetic studies.
