In addition, hsa-miR-320b was shown to restrain NPC cell proliferation and enhance mitochondrial fragmentation and apoptosis both in vitro and in vivo by targeting TP53 regulated inhibitor of apoptosis 1 (TRIAP1), which is a TP53-regulated inhibitor of apoptosis [83]. This evidence concerns the gene TRIAP1 and nasopharyngeal carcinoma.
