Experimental Protocol

Samples from three frozen livers from each group (newborn exposed and unexposed, 10 week old exposed and unexposed), and from separate litters, were homogenized and total RNA purified using mirVANA RNA pufification kits (Ambion, Carlsbad, CA). RNA was quantitated and intergrity determined on a Nanochip using a Bioanalyzer (Agilent, Santa Clara, CA). Microarray analyses for miRNAs abundance in total liver RNAs was performed by Exiqon (Woburn, MA) using two-color design against mouse standard total RNA (Ambion, now part of Applied Biosystems) and Exiqon LNA 1500 microarrays. Microarray analyses for mRNA abundance was performed using 2 color design against mouse standard total RNA (Stratgene, LaJolla, CA) and 44k arrays produced at the NIA . The processed data on Exiqon LNA-1500 are attached as a Series supplementary file. The data are based on the same samples as described in Agilent data submitted here. The supplementary data includes only the murine miRNA data on the array because these are the only data supplied by Exiqon. The relationship between GEO's sample names here (Agilent data) and column heads of spreadsheets (Exiqon data) are described in the first sheet of supplemental file: Project_Summary_Report_Heather_Miller_01042009_MTE.xls
