From the genes differentially expressed between normal tissue and cervical cancer (1015) we selected nine genes (BRCA1, SPP1, PRKAR1B, LAMA2, PCNA, STK17A, VAV2, DUSP1, and APP), which had either been reported in other cancers or were potential biomarkers as they were secretory proteins. Here, PRKAR1B is linked to cervical carcinoma.
