Figure 7: The effect of Fxr−/− on ontogenic expression of nuclear receptors and core transcription factors in liver. Heat map of expression profiles are drawn for all nuclear receptors and main hepatic transcription factors (genes labeled on the right) with significant differential expression between C57BL/6 and Fxr−/− samples. For each gene, the value of log2(1+[fold change of mean FPKM]) over the ages are calculated to show the trends of expression. The three gene names in red color have higher expression in C57BL/6 samples than in Fxr−/− samples.
