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....

Background:

Single-cell RNA sequencing (scRNA-seq) reveals cell heterogeneity and disease mechanisms.
scRNA-seq data analysis faces challenges like noise from low capture rates and dropout events.

Purpose of the Study:

To develop a deep neural generative framework for denoising scRNA-seq datasets.
To enhance feature preservation and cell type-specific gene expression patterns.

Main Methods:

Proposed a deep neural generative framework: dynamic batching adversarial autoencoder (DB-AAE).
DB-AAE directly captures optimal features and preserves biological signals.

Main Results:

DB-AAE demonstrated superior denoising accuracy compared to other methods on simulated and real datasets.
The method effectively preserved biological signals and cell type-specific gene expression.
DB-AAE improved the accuracy of pseudo-time inference algorithms.

Conclusions:

DB-AAE is an effective tool for denoising scRNA-seq data.
The framework enhances the quality and reliability of downstream analyses in single-cell research.
