Fig. 6From: Uterine transcriptome analysis reveals mRNA expression changes associated with the ultrastructure differences of eggshell in young and aged laying hensPathway analysis of differential expressed genes of uterus in aged hen group (72 wk. of age) relative to young hen group (42 wk. of age). The differential expressed genes in aged hen group relative to young hen group were only enriched (Q < 0.05) in the peroxisome proliferator-activated receptor (PPAR) signaling pathway (rich factor = 8.90)Back to article page
