Hsa_circ_0003288 increases PD-L1 expression levels by sponging miR-145. a and c Hsa_circ_0003288 reverses miR-145 induced inhibition of PD-L1 mRNA expression measured using qRT-PCR in HepG2 and Huh7 cells. b and d Hsa_circ_0003288 reverses miR-145 induced inhibition of PD-L1 protein expression measured using western blotting in HepG2 and Huh7 cells
