FASN Targeted by miR-497-5p Regulates Cell Behaviors in Cervical Cancer

Cervical cancer (CC) is a severe malignant tumor. Recently, more and more evidence has shown that abnormal expression of fatty acid synthase (FASN) occurs in varying tumors. Therefore, this investigation devoted to FASN in CC along with its upstream regulatory miRNA. Their expression levels were tested by qRT-PCR. Cell function experiments were undertaken to test tumor-related cell behaviors. Identification of their interplay was conducted by western blot and dual-luciferase methods. As analyzed, miR-497-5p was at low level in human CC cell lines, while FASN was overexpressed and demonstrated as a target of miR-497-5p. Cell function experiments demonstrated the targeting of miR-497-5p to FASN 3'-UTR, thus restraining CC development. To sum up, this investigation primarily revealed miR-497-5p/FASN axis in CC, by which potential CC biomarkers, could be developed. However, the mechanism of the axis was not determined in vivo, as one of the study limitations.
