Kcnq1ot1 regulates miR-506-3p to mediate SYPL1. A starBase website predicted the targeting relationship between miR-506-3p and SYPL1; B Dual luciferase reporter gene assay was utilized to confirm the targeting relationship between miR-506-3p and SYPL1; C-D RT-qPCR and western blot assay were conducted to detect SYPL1 expression; E–G Pearson test was employed to analyze the correlation between SYPL1 and YY1/Kcnq1ot1/miR-506-3p in OSCC tissues; * P < 0.05 compared with the Vector group; # P < 0.05 compared with the si-NC group; & P < 0.05 compared with mimic-NC group; Measurement data were expressed as mean ± standard deviation
