DNA microarrays containing virtually every gene of Saccharomyces cerevisiae were used to carry out a comprehensive investigation of the temporal program of gene expression accompanying the metabolic shift from fermentation to respiration, and the expression patterns of many previously uncharacterized genes provided clues to their possible functions.Abstract:
DNA microarrays containing virtually every gene of Saccharomyces cerevisiae were used to carry out a comprehensive investigation of the temporal program of gene expression accompanying the metabolic shift from fermentation to respiration. The expression profiles observed for genes with known metabolic functions pointed to features of the metabolic reprogramming that occur during the diauxic shift, and the expression patterns of many previously uncharacterized genes provided clues to their possible functions. The same DNA microarrays were also used to identify genes whose expression was affected by deletion of the transcriptional co-repressor TUP1 or overexpression of the transcriptional activator YAP1. These results demonstrate the feasibility and utility of this approach to genomewide exploration of gene expression patterns.read more

Principles of transcriptional control in the metabolic network of Saccharomyces cerevisiae.
TL;DR: It is found that transcription regulation biases metabolic flow toward linearity by coexpressing only distinct branches at metabolic branchpoints, and transcriptional regulation defined a hierarchical organization of metabolic pathways into groups of varying expression coherence.

Measuring absolute expression with microarrays with a calibrated reference sample and an extended signal intensity range.
TL;DR: This study hybridizes each sample against labeled oligos complementary to every microarray feature, and demonstrates that results from this type of hybridization are accurate and retain absolute abundance information far better than conventional microarray ratios.

Using the principle of entropy maximization to infer genetic interaction networks from gene expression patterns
TL;DR: Analysis of microarray data from genes in Saccharomyces cerevisiae chemostat cultures exhibiting energy metabolic oscillations identifies a gene interaction network that reflects the intracellular communication pathways that adjust cellular metabolic activity and cell division to the limiting nutrient conditions that trigger metabolic oscillation.

TL;DR: It is proposed that in cells with compromised mitochondrial function, the RTG genes take control of the expression of genes leading to the synthesis of α-ketoglutarate to ensure that sufficient glutamate is available for biosynthetic processes and that increased flux of the glyoxylate cycle, via elevated CIT2 expression, provides a supply of metabolites entering the TCA cycle sufficient to support anabolic pathways.

Quantitative monitoring of gene expression patterns with a complementary DNA microarray.
TL;DR: A high-capacity system was developed to monitor the expression of many genes in parallel by means of simultaneous, two-color fluorescence hybridization, which enabled detection of rare transcripts in probe mixtures derived from 2 micrograms of total cellular messenger RNA.

A DNA microarray system for analyzing complex DNA samples using two-color fluorescent probe hybridization.
TL;DR: This work describes a general experimental approach, using microscopic arrays of DNA fragments on glass substrates for differential hybridization analysis of fluorescently labeled DNA samples, and demonstrates the utility of DNA microarrays in the analysis of complex DNA samples.
