DNA Microarrays
The DNA microarray is one of the more recent advances in toxicogenomics. Microarrays have the ability to detect “changes in gene expression associated with specific types of toxic response.” (7) A DNA chip contains sequences of known genes that have been attached when manufactured. In the lab two samples are prepared, one being exposed to the putative toxicant. RNA is then isolated and extracted. Reverse transcriptase is used to create cDNA which is single stranded.

To overcome these limitations, it has been proposed that a DNA microarray based on the theory of Compressed Sensing (CS) - a Compressed Sensing Microarray - would require fewer “intelligently chosen” sensors to identify the same number of organisms [2]. Compressed sensing is an emerging signal-processing technique that applies to signals with sparse, or at least rapidly decaying, representation in some orthogonal basis. [3–5]. As with other com-pression techniques, it extracts the minimal information required to accurately reconstruct the signal.

Microarrays
Main components of microarrays: (1) Hybridization (2) The ability to attach a known DNA molecule to a solid surface. Expression: To measure RNA (1) Convert RNA to DNA (2) Measure DNA This is a common trick: to measure X in a cell, convert X to DNA and measure DNA. Microarray: basic idea. We try to measure a specific (short) DNA sequence called “the target”, which we measure using “a feature”. (1) Take a known DNA sequence and attach many single stranded copies in a specific place on a solid surface.

Genome Probing Using DNA Microarrays
In microarray technology, DNA hybridization is turned upside down. Instead of the target DNA being fixed to a substrate, such as a filter in Nothern and Southern Blots, and a labeled probe applied, the probe is fixed and a labeled pool of DNA or cDNA molecules is applied. In the example shown in Figure 9.3 the microarray contains Expressed Sequence Tags (ESTs), cDNAs corresponding to expressed genes. (You are cloning ESTs from Arabidopsis.) The technique can be used to determine what genes are turned on in response to serum.

The Structure of DNA
DNA is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine). Using research from many sources, including chemically accurate models, Watson and Crick discovered how these six subunits were arranged to make the the structure of DNA. The model is called a double helix because two long strands twist around each other like a twisted ladder.

DNA microarray analysis—a multimillion-dollar-a-year industry—identifies gene activation in living, complex biological systems. DNA microarrays monitor the behavior of thousands of genes over time by detecting changes in the expression of as many as 30,000 different genes on one small chip. The technique has been used to study some of the most important biological systems, including how cells normally divide (the cell cycle) and immune responses to disease and infection.

Practical Exercises in Microarray Data Analysis
Practical analyses of microarray data. This web contains links to different exercises and labs that I have taught along the time using different software tools and datasets. Although, at the moment, it is somewhat heterogeneous I have found it interesting to combine them in order o highlight what can or can't be done with each tool (of course it often means what the time, or the knowledge allowed to do or not to do).

DNA chip technology in the study of
The advent of DNA microarray technology has ushered in an era of systems biology whereby researchers can study the transcriptional behavior of thousands of genes in parallel. Advances in manufacturing techniques and informatics, and the availability of several genome sequences have furthered these capabilities to the point where whole-transcriptome studies can be accom-plished in yeast, ies and plants, and soon will be pos-sible in mammals.

Scientists rely on DNA microarrays for two very different purposes. So-called genotype applications compare the DNA on a chip with DNA in a tissue sample to determine which genes are in the sample or to decipher the order of code letters in as yet unsequenced strings of DNA. ... Several techniques that do not involve mi-croarrays can reveal the jobs performed by newly discovered genes (or, more. AN AORFRACYOMPANIES.
