Self-organizing map analysis of transcripts significantly differentially expressed after 1,25(OH)2D treatment in RWPE1 cells. Transcripts that were found to be significantly differentially expressed (FDR<5%) in at least one time point by 1,25(OH)2D treatment (n = 5435) were clustered into 12 groups using self organizing map. The X-axis for each cluster represents hours after treatment (6, 24 and 48 h). The Y-axis for each cluster represents normalized relative level of mRNA expression (in arbitrary units). The number of genes within each cluster in listed at the top, along with the cluster number.
