A microarray effect was not included in the model due to the design of Group 2 studies that included two honey bee samples not present on multiple microarrays.
Using microarrays, profound transcriptional effects were observed in the heart at the end of the experiment, 9 weeks after the feeding of TTA stopped.
The list of differentially expressed genes (intersection of Cufflinks and microarray breed effects) was compared against total expressed genes in male gonads (background).
No significant dye effects were detected in all microarray slides (data not shown).
However, the degrees of their effects were largely different and depended on which microarray data were used.
Fixed effects were treatment (SCE = infection and NUI = control), and random effects included cow and microarray.
Gene transcript levels are directly derived from microarray data, while microRNA regulatory effects are modeled using mRNA sequence information, with the assumption that mRNA with similar putative microRNA binding sites are likely to experience similar posttranscriptional regulation.
Batch effects are pervasive for microarray data and LRR data are very sensitive to such.
When RNA degradation effects are detected in microarray experiments, a correction of the induced bias in probe intensities is advised.
