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...

Ribosome Profiling

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Genome Annotation and Assembly

Genome Annotation and Assembly

The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Summary

This summary is machine-generated.

Doublets/multiplets are artifacts in single-cell RNA sequencing (scRNA-seq) data that can skew results. We developed vaeda, a computational tool using variational auto-encoders, to accurately identify and remove these artifacts, improving data reliability.

Area of Science:

Genomics
Bioinformatics
Computational Biology

Background:

Single-cell RNA sequencing (scRNA-seq) is crucial for studying cellular heterogeneity.
Technical artifacts, such as doublets/multiplets (two cells barcoded as one), are prevalent in scRNA-seq data.
These artifacts introduce artificial transcriptional profiles, potentially biasing downstream analyses.

Purpose of the Study:

To develop and evaluate a computational method for annotating and removing doublets/multiplets from scRNA-seq datasets.
To provide a robust tool for improving the accuracy of scRNA-seq data analysis.

Main Methods:

Introduction of vaeda (Variational Auto-Encoder for Doublet Annotation), a novel approach.
Integration of a variational auto-encoder with Positive-Unlabeled learning.
Application and benchmarking of vaeda against seven existing doublet annotation methods on 16 datasets.

Main Results:

Vaeda demonstrates competitive performance in generating doublet scores and binary doublet calls.
Vaeda outperforms other Python-based doublet annotation methods.
The method proves robust and reliable for scRNA-seq doublet annotation.

Conclusions:

Vaeda is a powerful and effective tool for addressing the challenge of doublets/multiplets in scRNA-seq data.
Its performance makes it a valuable addition to Python-based scRNA-seq analysis workflows.
The tool is publicly available for the research community.
