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...

RNA Editing

RNA Editing

RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

Background:

Adapter trimming is crucial for small RNA sequencing (sRNA-seq) data analysis.
Existing tools require adapter sequences, which are often missing, incorrect, or inaccessible in public datasets.
Manual adapter identification is laborious and prone to errors, especially with randomized adapters.

Purpose of the Study:

To develop a method for fast and accurate detection of adapter patterns in sRNA-seq data.
To provide a tool that does not require prior adapter sequence information.
To enhance the reproducibility and reusability of sRNA-seq datasets.

Main Methods:

Development of FindAdapt, a Python package for automated adapter sequence detection.
Evaluation using 180 simulated datasets with varied read structures.
Validation on 3,184 real-world sRNA-seq datasets from diverse library preparation kits.

Main Results:

FindAdapt successfully identified adapter sequences across all tested simulation datasets.
The tool demonstrated high accuracy on a large cohort of real-world datasets.
FindAdapt significantly outperforms existing adapter detection approaches.

Conclusions:

FindAdapt offers a robust, information-free solution for adapter trimming in sRNA-seq.
The software is easily integrated into existing bioinformatics pipelines.
FindAdapt enhances the reliability and accessibility of sRNA-seq data analysis.
