MAPK3 and cervical carcinoma: It is worth noting that a large number of recent studies have found that miRNAs are regulated by circRNAs and involved in the progression of cervical cancer, such as circNFATC3 which promotes the development of cervical cancer through sponging miR-9-5p [13], circNRIP1 which regulates the PTP4A1/ERK1/2 pathway through sponging miR-629-3p and promotes the migration and invasion of cervical cancer [14], and circ_0000520 sponge miR-146b-3p released PAX5 and expressed the progression of cervical cancer in vivo and in vivo [22].
