PLK1 and cervical squamous cell carcinoma: It could be conjectured that PLK1-related carcinogenesis of CESC might relate to the active involvement of correlated genes in pathways such as DNA replication, cell cycle, mismatch repair and Ras signaling pathway; PLK1-related carcinogenesis of cervical adenocarcinoma might relate to the participation of correlated genes in pathways such as cell cycle, DNA replication, base excision repair and homologous recombination.
