For example, miRNAs may function as oncogenes or tumor suppressors to regulate the occurrence and development of cervical cancer through special signaling pathways, including the PI3K-AKT pathway 25, Notch pathway 26, E6-p53 pathway 27, E7-pRb pathway 28, Wnt/β-catenin pathway 29, NF-κB pathway 30, and Hedgehog pathway 31. The gene discussed is TP53; the disease is cervical cancer.
