Enrichment test of PMRR genes in the hubs in I4, I24, H4 and H24 GCNs.
The test was conducted using the numbers of hub genes, PMRR genes and non-PMRR genes in each GCN. Solid bars represent the proportions of hub genes among PMRR genes; striped bars represent the proportions of hub genes among non-PMRR genes. Error bars indicate ±1 s.e.m. The P-values shown were calculated based on Fisher’s exact test.
