Expression data from Rat liver 48 hours after treated with different toxic compounds.


ABSTRACT: Rat has been treated with different compounds with the purpose of investigating toxicological mechanisms. But toxic and non-toxic compounds has been administered. 3 toxic (ANIT, DMN, NMF) 3 non-tox (Caerulein, dinitrophenol(DNP), Rosiglitazone) in 5-plicates (30 arrays in all) and 9 untreated (control), 39 samples in all. The array data was used to identify genes with biomarker potential for detecting toxic properties of compounds. Keywords: other Rats was treated with different compounds and RNA from liver was extracyed after 48 hours. Microarrays (GeneChip Rat230 version 2) was run on the RNA

A large number of databases are currently being implemented within toxicology aiming to integrate diverse biological data, such as clinical chemistry, expression, and other types of data. However, for these endeavors to be successful, tools for integration, visualization, and interpretation are needed. This paper presents a method for data integration using a hierarchical model based on either principal component analysis or partial least squares discriminant analysis of clinical chemistry, expr  ...[more]
