Microarray Experiment Design
Type I: (n = 2) Differential Expression
–How is this gene expressed in target 1 as compared to target 2?
–Which genes show up/down regulation between the two targets?
Type
II: (n > 2) Data
Partitioning
–How does the expression of gene A vary over time, tissues, or treatments?
–Do any of the expression profiles exhibit similar patterns of expression?
