Enriched gut development-related and immune function-related functions of selected miRNAs.

*miRNA categories were represented by different letters: A: Predominant miRNA expressed in GIT; B: Temporal DE miRNA in MJ; C: Temporal DE miRNA in RU and MJ; D: Temporal DE miRNA in IL; E: Temporal DE miRNA in MJ and IL; F: Regional DE miRNA (RU vs IL; RU vs MJ); G: Temporal DE miRNA in MJ; Regional DE miRNA (RU vs IL; RU vs MJ); H: Positive correlated with total bacterial density in RU; I: Negatively correlated with the density of Bifidobacterium on D21 in IL; J: Positively correlated with the density of both Bifidobacterium and Lactobacillus on D42; K: Regional DE miRNA (RU vs IL; IL vs MJ), temporal DE miRNA in IL and positively correlated with the density of both Bifidobacterium and Lactobacillus on D21.
