Figure 5: Gene ontology analysis for over-expressed genes during postnatal liver maturation compared to day 60 in Fxr−/− mice. (A) Heat map for GO categories with significant gene over-expression at ages of day −2, 1, 5, 20, and 25. The color represents the false discovery rate of each GO category. The numbers on the right are the cumulative number of GO categories. The brackets B and C are used to label different groups of GO categories. Representative GO categories in each bracket are show in the corresponding panels of (B) and (C). The FDR values with red color in panel (B) indicate the same GO categories having a FDR > 0.05 in the age-matched C57BL/6 samples.
