Fig. 8From: Hsa_circ_0136666 stimulates gastric cancer progression and tumor immune escape by regulating the miR-375/PRKDC Axis and PD-L1 phosphorylationThe signal pathway diagram of hsa_circ_0136666 promoting gastric cancer progression. Specifically, hsa_circ_0136666/miR-375/PRKDC upregulates DNA-PK protein expression, driving PD-L1 phosphorylation. The increased stability of PD-L1 results in abnormal aggregation on the surface of the cell membrane, thus leading to immune escapeBack to article page
