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...

Background:

Single-cell RNA sequencing (scRNA) generates large datasets but faces challenges from batch effects and high dimensionality.
Existing batch correction algorithms struggle with significant variations in cell type composition across datasets, leading to overcorrection.

Purpose of the Study:

To develop a novel method, SSBER, for robust batch effect correction in scRNA data.
To address the limitations of current algorithms when dealing with diverse cell type distributions between batches.

Main Methods:

SSBER utilizes biological prior knowledge to guide the batch effect correction process.
The method is designed to preserve biological variations while removing technical noise.

Main Results:

SSBER demonstrates superior performance in correcting batch effects compared to mainstream algorithms.
The method is particularly effective when cell type composition varies considerably or when similar cell types are present across batches.

Conclusions:

SSBER offers an effective solution for batch effect correction in scRNA data, especially in complex biological samples.
The approach enhances the reliability of downstream analyses by accurately integrating data from different sources.
