Based on DAVID 6.7 (http://david.abcc.ncifcrf.gov/) software, there were 14 pathways (p < 0.05) in Module 1: Chemokine signaling pathway, Neuroactive ligand–receptor interaction, Taste transduction, Cytokine–cytokine receptor interaction, Gap junction, Melanogenesis, Progesterone-mediated oocyte maturation, Intestinal immune network for IgA production, Dilated cardiomyopathy, GnRH signaling pathway, Complement and coagulation cascades, Oocyte meiosis, Vascular smooth muscle contraction, and Calcium signaling pathway (Table 2). Here, GNRH1 is linked to dilated cardiomyopathy.
