Data was processed and analysed using the National Institute on Aging (NIA) array, The Database for Annotation, Visualisation and Integrated Discovery (DAVID), GenePattern, and visual anaysis tool (visANT) software.
Paired comparisons using National Institute on Aging (NIA) array analysis determined a correlation greater than 0.98 for eEPC biological replicates, and greater than 0.97 for OEC replicates (Additional File 1 Table S2).
Pearson correlations were determined between the index and PR mRNA expression level as well as each clinical parameter (age, array determined ERBB2 status, grade and nodal status).
After quantile normalization (using limma package in R) on the age arrays (25 young and 26 older subjects, Table S1), we first determined the number of genes significantly differentially expressed with age, by performing on a probe-by-probe basis, 24354 two-sample t-tests.
Recently, chemical biology approaches have enabled researchers to analyze complicated biological processes such as aging using vast arrays of chemical compounds.
While it doesn't necessarily match the manic mash-up that was Shaun, the strong script by Wright & Pegg nonetheless manages to take a meditation on aging, toss in an array of alien space robots that bleed blue, and end up with something that's somber, scary, and absolutely hilarious.
At the pathway level, upregulated inflammatory and endosomal processes appear consistent in rodent aging across multiple labs, array platforms, and brain regions [27], [28], [29], [49], [50], [51], [52], [53], [54], [55], [74] (although see [75]).
The expression of 57 miRNAs in mouse quadriceps muscles was altered by aging using a miRNA array [ 10].
Recently, DNAm has also been shown to be associated with aging in a wide array of organisms, ranging from yeast to humans [ 2, 5, 6].
