PDK3 overexpression or inhibition of miR-7-5p reverses HNSCC proliferation and invasion after hsa-circ-0013561 silencing. A–D Colony formation and EdU assays showing Hep-2 proliferation. ^**p < 0.001 vs NC. E–H Transwell and wound healing assays showing invasion and migration of Hep-2 cells. ^*p < 0.05, ^**p < 0.01, ^****p < 0.0001 vs NC. All data are expressed as the mean ± SD. All experiments were repeated three times
