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...

Next-generation Sequencing

Next-generation Sequencing

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features....

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...

Area of Science:

Genomics
Bioinformatics
Computational Biology

Background:

High-throughput sequencing is advancing rapidly, necessitating robust quality control for clinical and industrial use.
Optimizing sequencing output and reducing costs are critical in production settings.
Existing quality monitoring methods may not be sufficient for large-scale sequencing operations.

Purpose of the Study:

To develop a predictive framework, SeqControl, for monitoring and controlling sequencing quality and coverage.
To establish multivariate models for predicting sequencing outcomes based on key metrics.
To enable real-time quality assessment in high-throughput sequencing pipelines.

Main Methods:

Developed SeqControl, a framework utilizing 15 metrics (coverage, distribution, base-wise quality).
Derived multivariate models using whole-genome sequences from 27 prostate cancer and 26 normal samples.
Validated SeqControl's predictive accuracy for sequencing depth and sample classification.

Main Results:

SeqControl accurately predicted required sequencing for desired coverage depth (AUC = 0.993).
The framework successfully classified clinically relevant formalin-fixed, paraffin-embedded samples.
Predictions were reliable even with limited data (e.g., one-eighth of a sequencing lane, AUC = 0.967).

Conclusions:

SeqControl provides a robust method for real-time sequencing quality and coverage monitoring.
The framework can be integrated into existing pipelines to enhance efficiency and reduce costs.
SeqControl supports the routine clinical and industrial application of high-throughput sequencing.
