Description |
Gene expression data from LNCaP cells transfected with miR-205.
|
Data processing |
The data were analyzed with R (version 2.9.0) and BioConductor (version 2.4). Quality assessment of arrays included exploration of distributions of probe intensities across all arrays, of average background values, and RNA quality was examined by RNA degradation plots. Diagnostic plots based on a probe level model (PLM) have been used to rule out chips with spatial artifacts (Chip pseudo-images, normalized unscaled standard error (NUSE) plot and relative log expression (RLE) plot). Background adjusted normalized data was retrieved by the RMA (robust multi-array average) procedure. Loss of mRNA expression was conducted by fitting a linear model using the R package limma. Reliable variance estimations were obtained by empirical Bayes moderated t-statistics. False discovery rate was controlled by Benjamini-Hochberg adjustment.
