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....

Genomics
Biotechnology

Background:

Accurate quantification of microRNAs (miRNAs) and messenger RNAs (mRNAs) is crucial for understanding gene expression.
Existing digital profiling technologies often require substantial sequencing depth, limiting scalability and increasing costs.
There is a need for efficient, cost-effective methods for large-scale gene expression analysis.

Purpose of the Study:

To introduce and validate a novel RNA profiling method, modular, early-tagged amplification (META) RNA profiling.
To demonstrate that META RNA profiling can simultaneously quantify a broad panel of miRNAs or mRNAs across numerous samples.
To show that META RNA profiling requires significantly less sequence depth compared to current digital profiling technologies.

Main Methods:

The META RNA profiling method involves assigning quantitative tags during the reverse transcription step.
This tagging allows for up-front sample pooling prior to competitive amplification and deep sequencing.
The process is designed to be simple, scalable, and cost-effective.

Main Results:

META RNA profiling successfully quantifies a broad range of miRNAs or mRNAs simultaneously.
The method demonstrates a significant reduction in required sequence depth compared to existing technologies.
The approach proved to be practical for large-scale gene expression studies.

Conclusions:

META RNA profiling offers a highly practical, scalable, and inexpensive solution for gene expression studies.
The method's reduced sequencing depth requirement makes large-scale analyses more feasible.
This innovation has the potential to advance the field of transcriptomics and biomarker discovery.
