Summary
Gene expression levels correlate with their functional relationships and chromosomal proximity. This suggests that a gene's function is linked to its mRNA expression patterns within biological pathways.
Area of Science:
- Genomics
- Systems Biology
- Bioinformatics
Context:
- Understanding gene function and regulation is crucial in molecular biology.
- Gene interactions within pathways and their physical locations on chromosomes are key factors in biological processes.
- Analyzing mRNA expression levels provides insights into gene activity.
Purpose:
- To investigate the relationship between gene functional correlation, chromosomal location, and mRNA expression levels.
- To determine if genes with similar functions and proximity exhibit correlated expression patterns.
- To explore the consistency of mRNA expression with the intensity of functional relationships between genes.
Summary:
- Utilized KEGG pathway information and LocusLink chromosome locations with three similarity metrics.
- Found significant correlations in mRNA expression levels among functionally related and chromosomally close genes.
- Concluded that gene function within a pathway is correlated with its mRNA expression level.
Impact:
- Provides evidence supporting the link between gene expression, function, and genomic organization.
- Highlights the utility of integrating pathway and location data for expression analysis.
- Suggests a basis for predicting gene function based on expression profiles and network properties.

Epistasis Analysis
Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. Epistasis often involves one gene masking or interfering with the expression of another (antagonistic epistasis). Epistasis often occurs when different genes are part of the same biochemical pathway. The...
DNA Microarrays
Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...
Protein Networks
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

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.
What is Gene Expression?
Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

What is Gene Expression?
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is comprised of nucleotides and proteins are comprised of amino acids, a mediator is required to convert the information encoded in DNA into proteins. This mediator is the messenger RNA (mRNA). mRNA copies the blueprint from DNA by a process called transcription. In eukaryotes, transcription occurs in the nucleus by complementary base-pairing with the DNA template. The mRNA is then processed and...
