Proceedings Genome-wide estimation of gender differences in the gene expression of human livers: Statistical design and analysis

Testing for treatment effects on gene ontology (2008)

Lee, Taewon, Desai, Varsha G, Velasco, Cruz, Reis, Robert, Delongchamp, Robert R

Abstract In studies that use DNA arrays to assess changes in gene expression, it is preferable to measure the significance of treatment effects on a group of genes from a pathway or functional...

Designing Toxicogenomics Studies that use DNA Array Technology (2008)

Robert R. Delongchamp, Cruz Velasco, Varsha G. Desai, Taewon Lee, James C. Fuscoe

Background: Bioassays are routinely used to evaluate the toxicity of test agents. Experimental designs for bioassays are largely encompassed by fixed effects linear models. In toxicogenomics studies...

A method for computing the overall statistical significance of a treatment effect among a group of genes (2006)

Delongchamp, Robert, Lee, Taewon, Velasco, Cruz

Abstract Background In studies that use DNA arrays to assess changes in gene expression, our goal is to evaluate the statistical significance of treatments on sets of genes. Genes can be grouped by a...

Genome-wide estimation of gender differences in the gene expression of human livers: Statistical design and analysis (2005)

Delongchamp, Robert R, Velasco, Cruz, Dial, Stacey, Harris, Angela J

Abstract Background Gender differences in gene expression were estimated in liver samples from 9 males and 9 females. The study tested 31,110 genes for a gender difference using a design that...
