    Cervical cancer (CC) is a common disease in women characterized by high recurrence rate. LncRNA ceramide synthase 6 antisense RNA 1 (CERS6-AS1) has been found to play a crucial role in the progression of breast cancer and pancreatic cancer. Nevertheless, the regulatory role of CERS6-AS1 in CC remains largely unclear. Here, we found that the expression of CERS6- AS1 was upregulated in CC tissues and cell lines compared with adjacent tissues and normal human cervical epithelial cells. CERS6-AS1 overexpression promoted proliferation and invasion, and inhibited apoptosis in CC cells, while silencing of CERS6-AS1 led to the opposite results. CERS6-AS1 was verified as a sponge of miR-6838-5p by RNA pull-down and luciferase reporter gene assays. Functional investigations revealed that CERS6-AS1 knockdown inhibited proliferation and invasion, and promoted apoptosis in CC cells, which was reversed by miR-6838-5p inhibitor. Furthermore, forkhead box P2 (FOXP2) was identified as a target for miR-6838-5p, and overexpression of miR6838-5p decreased the expression level of FOXP2. Besides, CERS6-AS1 was able to sponge miR-6838-5p to accelerate CC cell proliferation and invasion and inhibited cell apoptosis through upregulating FOXP2 expression. In general, CERS6-AS1 was able to regulate CC cell proliferation, invasion and apoptosis by the miR-6838-5p/FOXP2 axis, which suggested that CERS6-AS1 may be a potential target for the treatment of CC.
