DNA Microarrays

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...

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.

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...

FISH - Fluorescent In-situ Hybridization

FISH - Fluorescent In-situ Hybridization

Fluorescence in situ hybridization, or FISH, was developed in the early 1980s and has quickly become one of the most widely used techniques in cytogenetics. Labeled probes are used to bind complementary DNA or RNA sequences on a chromosome or in a region within a cell. Earlier, the probes could only be obtained by cloning or reverse transcription of a DNA template. Currently, the probe oligonucleotides can be synthesized synthetically. Additionally, with the advancement of optical techniques,...

Cis-regulatory Sequences

Cis-regulatory Sequences

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Background:

Accurate functional annotation of microarray probes is critical for interpreting biological processes.
Outdated probe annotations hinder the analysis of gene expression data.
Genome database updates necessitate continuous annotation refinement for microarray probes.

Purpose of the Study:

To develop a robust pipeline and database for annotating microarray probes.
To ensure microarray probe annotations are current and accurate.
To facilitate the analysis of gene expression data with up-to-date information.

Main Methods:

Designed a pipeline integrating NCBI BLAST, Perl, and MySQL.
Utilized publicly available genome databases for annotation.
Applied the pipeline to annotate chicken microarray probes from an Eimeria infection experiment.

Main Results:

Successfully annotated 770 out of 791 differentially expressed chicken probes.
Assigned at least one database entry (Ensembl, UniGene, DFCI) to the majority of probes.
Demonstrated the pipeline's effectiveness in a specific biological context.

Conclusions:

The developed pipeline offers a simple and robust method for maintaining accurate microarray probe annotations.
The pipeline is flexible and easily updated with new genomic information.
Ensures researchers have access to the latest annotation data for reliable analysis.
