As shown in Figure 8D–8F, significantly decreased levels of expression of both hsa-circ_0081534 and FN1 were found in the sh-circ_0081534 group, whereas hsa-circ_0081534 depletion subsequently and notably increased miR-508-5p expression in NPC tumor afflicted tissues. This evidence concerns the gene FN1 and nasopharyngeal carcinoma.
