Gene expression changes of common Wnt signaling targets in the E18.5 Pygo1 / Pygo2 null kidney. Microarray analysis was performed in triplicate on wild-type and Pygo1/2 compound null E18.5 kidneys. Possible Wnt targets were selected from those compiled at [39]. An initial gene list of 82 Wnt targets was created and then reduced to a total of 40 genes using an expression level restriction requiring the raw expression intensity to be >100 in at least 3 samples. Pygo1 and Pygo2 probes were included to demonstrate significant changes in expression levels.
