However, staining of TH (tyrosine hydroxylase, dopaminergic neuron marker) or VAChT (choline acetyltransferase, cholinergic neuron marker) was not significantly increased in PNI-positive cervical cancer tissues (Fig. S1g, Supporting Information), indicating that sympathetic or parasympathetic nerve, resident in the cervix, were not directly involved in the neurogenesis during PNI of cervical cancer. Here, SLC18A3 is linked to cervical carcinoma.
