Amongst the top ten pathways in the 3 h, 12 h, and 24 h groups, 5, 4, and 6 non-overlapping pathways were identified, respectively. Only one overlapping pathway was identified among all the three groups, and several overlapping pathways were detected between the 3 h and 12 h groups (3 pathways), 12 h and 24 h groups (2 pathways), or 3 h and 24 h groups (1 pathway) (Figure 1b).
