Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
Total RNA from three replicate cultures of wild-type and mutant strains was isolated and the expression profiles were determined using Affymetrix arrays. Comparisons between the sample groups allow the identification of genes regulated by histone H2B K111A mutant.
Publication Title
Novel functional residues in the core domain of histone H2B regulate yeast gene expression and silencing and affect the response to DNA damage.

Description
Examined gene expression changes in a histone H2A R78A mutant in Saccharomyces cerevisiae relative to wild-type cells. THe overall goal of this study was to determine the functions of histone 'sprocket' arginine residues, which insert into the DNA minor groove in the nucleosome. We examined the roles of sprocket arginine mutants in gene expression, histone incorporation, and DNA repair.

Description
The use of low quality RNA samples in whole-genome gene expression profiling remains controversial. It is unclear if transcript degradation in low quality RNA samples occurs uniformly, in which case the effects of degradation can be normalized, or whether different transcripts are degraded at different rates, potentially biasing measurements of expression levels. This concern has rendered the use of low quality RNA samples in whole-genome expression profiling problematic. Yet, low quality samples are at times the sole means of addressing specific questions – e.g., samples collected in the course of fieldwork.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
In this study we compared genes expressed in the unbudded portion of the Wolffian duct with the isolated ureteric bud to find genes novel to early kidney development. We used the Affymetrix Rat Genome 230 2.0 Array to compare the unbudded tissues with the budded samples.

Description
The RNA-directed DNA methylation (RdDM) pathway in plants controls gene expression via cytosine DNA methylation. The ability to manipulate RdDM would shed light on the mechanisms and applications of DNA methylation to control gene expression. Here, we identified diverse RdDM proteins that are capable of targeting methylation and silencing in Arabidopsis when tethered to an artificial zinc finger (ZF-RdDM). We studied their order of action within the RdDM pathway by testing their ability to target methylation in different mutants. We also evaluated ectopic siRNA biogenesis, RNA Polymerase V (Pol V) recruitment, targeted DNA methylation, and gene expression changes at thousands of ZF-RdDM targets. We found that co-targeting both arms of the RdDM pathway, siRNA biogenesis and Pol V recruitment, dramatically enhanced targeted methylation. This work defines how RdDM components establish DNA methylation, and enables new strategies for epigenetic gene regulation via targeted DNA methylation. Overall design: 40 RNA-seq

Description
Elf5 expression in mammary progenitor cells regulates a cell fate decision that establishes the alveolar cell lineage. In luminal breast cancer cells, increased Elf5 expression suppressed estrogen receptor and FoxA1 expression and was implicated in the acquisition of resistance to the cytostatic effects of antiestrogen therapy. We show that in the PyMT model of luminal breast cancer, increased Elf5 expression drives lung metastasis by recruiting myeloid-derived suppressor cells, and that this activity overcomes the epithelializing influence of Elf5. Breast cancer expression signatures identify a similar process in humans, and increased Elf5 immunohistochemical staining predicts poor prognosis in the luminal A subgroup. Thus Elf5 may promote escape from hormonal therapy and drive metastasis in luminal breast cancer.
