  1. aThe E score of the cluster was measured by minus log transformation of the geometric mean of the modified Fisher Exact EASE Scores of all annotation terms that belong to this cluster, and it was intended to order the relative importance of the different clusters. The fold enrichments (enrich.) of specific individual annotation terms were also indicated for the most biologically-informative terms within each cluster
  2. bLists of regulated proteins participating to each cluster were indicated. MeiS > LW: proteins having a higher abundance in pure Meishan than in pure Large White genotypes. LW > MeiS: proteins having a higher abundance in pure Large White than in pure Meishan genotypes. F1_MeiS > F1_LW: proteins having a higher abundance in crossbred (F1) fetuses gestated by MeiS sows when compared with those gestated by Large White sows. F1_LW > F1_MeiS: proteins having a higher abundance in crossbred (F1) fetuses gestated by Large White sows when compared with those gestated by Meishan sows
