Project description:Micorarray analysis was performed on RNA samples from hippocampal cultures infected with either Ad-aCaN or Ad-LacZ or uninfected. Each sample was applied to its own GeneChip (Rat RG-U34A; n=7-9 chips/group). Chips were then processed and scanned using Agilent Affymetrix GeneArray Scanner. MAS5 was used to determine signal intensity and presence/absence calls for the data.

Project description:For these data, we analyzed hippocampal gene expression of nine control and 22 AD subjects of varying severity on 31 separate microarrays. We then tested the correlation of each gene's expression with MiniMental Status Examination (MMSE) and neurofibrillary tangle (NFT) scores across all 31 subjects regardless of diagnosis. These tests revealed a major transcriptional response comprising thousands of genes significantly correlated with AD markers. Several hundred of these genes were also correlated with AD markers across only control and incipient AD subjects (MMSE > 20).

Project description:Gene expression in human optic nerve head (ONH) astrocytes exposed to either 60 mm Hg hydrostatic pressure (HP) or control ambient pressure (CP) was compared using Affymetrix GeneChip microarrays to identify HP-responsive genes. Primary ONH astrocytes from two male Caucasian donors (passage 4) were grown to 75% confluence and were exposed for 6, 24 or 48 h to control ambient pressure (CP6, CP24, CP48) or hydrostatic pressure (HP6, HP24, HP48), or harvested at the beginning of the pressure experiment (CP0). Total RNA was extracted using Qiagen RNeasy columns and converted to biotin-labeled cRNA by standard Affymetrix protocols available at web site http://pathology.wustl.edu/~mgacore/genechip.htm#Preparing. Hybridization of the labeled cRNA to Human Genome U95Av2 chips (Affymetrix) was carried out by using Genechip Instrument System (Affymetrix) at Genechip Core Facility of Washington University. A total of 44 chips were generated and distributed as follows: seven for control pressure (CP) at time 0, four CP at 6 h, seven for hydrostatic pressure (HP) at 6 h, eight for CP at 24 h, eight for HP at 24 h, five for CP at 48 h and five for HP at 48h P. The arrays were washed and stained with streptavidin-phycoerythrin followed by scanning on an Agilent GeneArray Scanner G2500A (Agilent Technologies, Palo Alto, CA), and then scanned by an Affymetrix GeneArray Scanner. Data was analyzed by Affymetrix Microarray Suite (version 5.0), linear regression analysis, and GeneSpring expression Analysis Software (version 6.0, Silicon Genetics). For analysis, the samples were scaled to the same target intensity (1500) to allow comparison of multiple samples, and raw data were normalized to median of each gene across all chips for fold change analysis using GeneSpring.

Mice were killed between 24 to 26 months of age, tissues removed, rapidly frozen on dry ice, and stored in liquid nitrogen. Total liver RNA was isolated from frozen tissue as described (T. Tsuchiya, J.M. Dhahbi, X. Cui, P.L. Mote, A. Bartke, S.R. Spindler, Physiological Genomics, Submitted). mRNA levels were measured using the Affymetrix mouse U74Av2 array according to standard protocols. After hybridization, arrays were scanned using a Hewlett-Packard GeneArray Scanner. Image analysis was performed as described (Cao SX, Dhahbi JM, Mote PL, and Spindler SR. Genomic profiling of short- and long-term caloric restriction effects in the liver of aging mice. Proc Natl Acad Sci U S A 98: 10630-10635, 2001).
