The table shows the process title (GO name), the number of gene reporters changed changed (changed), measured with the microarrays (measured) and the total number of genes present in the pathway MAPP (total) (for detailed description of pathway selection, see Methods).
However, other major markers of aging, including increased inflammatory signaling (based on cytokine array measures in the periphery and microarray measures in the hippocampus), impaired cognition, and altered synaptic plasticity, were not altered with PIO treatment.
Noise in gene expression and other microarray measures was estimated as the standard error of the averages of the measures across technical replicates.
Suppose we extend the analyses to two classes, with m1 independent microarrays in class 1 and m2 independent microarrays in class 2. Each microarray measures n genes.
These data confirm the observation that technical errors do not necessarily affect microarray measures.
The Illumina HumanMethylation450k microarray measures the methylation levels of more than 485,000 methylation sites.
The CORR procedure in SAS 9 (SAS Institute Inc., Cary, NC, USA) was used to calculate Spearman's rank-order correlation coefficient and test whether the correlation between the microarray ratio measures and qPCR ΔCt equalled zero for each EBV miRNA or pre-miRNA set.
Therefore, we measured how similar the two different platforms, open (RNAseq) and closed (microarray), measured gene expression levels by Pearson correlation and linear regression, on a gene-by-gene basis.
Using a DNA microarray, we measured and compared the expression intensities of all 4345 genes of each strain cultured under three different conditions.
Pan et al. used microarray to measure and analyze the apoptosis-related gene-expression profile in MF-processed BEL-7402 hepatoma cells and L-02 fetus liver cells [ 11].
