In contrast to Liu's result [34], NOD1 was shown to be significantly expressed in cervical squamous cell carcinoma (CSCC), and overexpression of NOD1 increased proliferation, invasion, and migration of CSCC cell lines by activating NF-κB and ERK signaling pathways and increasing IL-8 production [35–37]. This evidence concerns the gene NOD1 and cervical squamous cell carcinoma.
