SP1 transcriptionally activates circFAM126A in OSCC. (A) mRNA expression of SP1 in OSCC patients measured using qRT-PCR. (B) Correlation analysis of expression levels of SP1 and circFAM126A in OSCC patients. (C) Expression of circFAM126A detected by qRT-PCR. (D) Serial truncations of circFAM126A promoter inserted into pGL3 vector. (E, F) Interaction between SP1 and circFAM126A verified by luciferase assay. (G) Interaction between SP1 and circFAM126A verified by ChIP assay. **P<0.01.
