Fig. 5. Developmental expression of conserved microbially responsive genes in the digestive tracts of CONR zebrafish. Relative expression levels for mRNAs encoding apolipoprotein B (Apob), complement component 3 (C3), cytochrome P450 subfamily I polypeptide 1 (Cyp1a1), fasting-induced adipose factor (Fiaf), serum amyloid A1 (Saa1), and suppressor of cytokine signaling 3 (Socs3) were defined by DNA microarray experiments comparing 6-dpf versus 10-dpf, and 10-dpf versus 20-dpf CONR zebrafish digestive tracts, using an experimental scheme analogous to that shown in Fig. 4.
