For example, guanylate binding protein 1 pseudogene 1 (GBP1P1) and pituitary tumor-transforming 3 pseudogene (PTTG3P), were over-expressed in cervical cancer and PTTG3P was positively correlated with PTTG1 levels, which promote cervical cancer cells proliferation through cyclin B1 (CCNB) and increased CC cell invasiveness through upregulation of snail family transcriptional repressor 1 (SNAIL) and downregulation of E-cadherin [8, 9]. The gene discussed is SNAI1; the disease is cervical cancer.
