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 microarray-based...

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.

Genomics

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Background:

Technological advancements enable multiple analyses of biological data.
Integrating results from diverse analytical methods is crucial for unbiased research.
Prioritized gene lists are common outputs in genomic data analysis.

Purpose of the Study:

To address the limitations of standard rank aggregation methods in noisy biological data.
To introduce a novel robust rank aggregation (RRA) method for improved gene list integration.

Main Methods:

Developed a novel robust rank aggregation (RRA) method.
The method employs a probabilistic model to detect consistently ranked genes.
Assigns significance scores to genes based on their ranking relative to a null hypothesis.

Main Results:

The RRA method is parameter-free, robust to noise, outliers, and errors.
It effectively identifies statistically relevant genes using significance scores.
The approach is suitable for various biological settings requiring gene list integration.

Conclusions:

The proposed RRA method offers a robust and compelling solution for integrating noisy gene lists in genomics.
Its parameter-free nature and statistical rigor make it highly applicable.
The method is available as an R package, facilitating its use in the research community.
