Co-incubation experiments showed that Prevotella bivia increased the expression of three immunoregulatory proteins lysosomal associated membrane protein 3 (LAMP3), signal transducer and activator of transcription 1 (STAT1) and antigen peptide transporter 1 (TAP1) in cervical cancer cells under hypoxic conditions. This evidence concerns the gene TAP1 and cervical carcinoma.
