Fig. 8From: Oleuropein enhances radiation sensitivity of nasopharyngeal carcinoma by downregulating PDRG1 through HIF1α-repressed microRNA-519dWorking model of OL action in promoting radiation sensitivity. OL decreases HIF1α expression, which in turn represses miR-519d expression. miR-519d functions to directly target PDRG1 mRNA and inhibit its expression. PDRG1 is able to inhibit radiation sensitivity via the ATM-P53 axis. The overall effect of OL in NPC is then to promote radiation sensitivityBack to article page
