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...

Background:

Single-cell RNA sequencing (scRNA-seq) provides high-throughput gene expression data.
Data dropouts in scRNA-seq can obscure biological signals.
Imputation methods are developed to address scRNA-seq data dropouts.

Purpose of the Study:

To systematically evaluate recent imputation algorithms for scRNA-seq data.
To compare the performance of imputation methods across diverse datasets.

Main Methods:

Evaluated 11 imputation methods.
Utilized 12 real immunological scRNA-seq datasets and 4 simulated datasets.
Assessed performance based on numerical recovery, cell clustering, and marker gene analysis.

Main Results:

Most methods improved numerical recovery.
Imputation method performance varied across datasets and protocols.
No single method consistently excelled in cell clustering; some negatively impacted it.
Some methods identified novel cell subsets, but imputation challenges remain.

Conclusions:

Imputation method effects are dataset-specific.
The study highlights benefits and limitations of various imputation methods.
Provides data-driven guidance for scRNA-seq data analysis.
