Figure 6: Gene ontology analysis for under-expressed genes during postnatal liver maturation compared to day 60 in Fxr−/− mice. (A) Heat map for GO categories with significant gene under-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 bracket B is used to label a group of GO categories. (B) Representative GO categories in the bracket B. The FDR values with red color indicate the same GO categories having a FDR > 0.05 in the age-matched C57BL/6 samples.
