Homologous genes between the two species were identified using WGCNA, followed by protein-protein interaction(PPI) network construction and gene enrichment analysis. Disease-related mi RNAs and pathways were retrieved from mi R2 Disease database and Comparative Toxicogenomics Database(CTD), respectively.RESULTS: A total of 352 homologous genes were identified. Two pathways including "cell cycle" and "pathway in cancer" in CTD and enrichment analysis were identified and seven mi RNAs(including hsa-mi R-373, hsa-mi R-34 a, hsami R-129, hsa-mi R-494, hsa-mi R-503, hsa-let-7 and hsami R-518 c) were associated with RB. mi RNAs modulate "cell cycle" and "pathway in cancer" pathways via regulating 13 genes(including CCND1, CDC25 C, E2 F2, CDKN2 D and TGFB2).CONCLUSION: These results suggest that these mi RNAs play crucial roles in RB genesis through "cell cycle" and "pathway in cancer" pathways by regulating their targets including CCND1, CDC25 C, E2 F2 and CDKN2 D.展开更多
