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...

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Proteomics

Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Background:

Biclustering groups samples and features across biomedical data.
Existing methods struggle with multi-modal data (e.g., multi-omics) and integrating biological knowledge graphs.

Purpose of the Study:

To propose a novel Bayesian biclustering method (BGB) for integrative multi-modal data analysis.
To leverage biological knowledge graphs within a biclustering framework.

Main Methods:

Developed a Bayesian graph-guided biclustering (BGB) approach.
Introduced a hierarchical sparsity-inducing prior to incorporate graph information.
Established a unified framework for multi-view data modeling.
Employed Markov chain Monte Carlo for posterior sampling and inference.

Main Results:

BGB demonstrated superior performance compared to existing biclustering methods in simulations and real data.
The method effectively integrates biological graph information.
BGB successfully revealed biologically meaningful insights from heterogeneous multi-modal data.

Conclusions:

BGB offers a robust and effective approach for biclustering multi-modal biomedical data.
Integrating biological knowledge via graphs enhances biclustering analysis.
The method has the potential to uncover novel biological discoveries from complex datasets.
