As shown in Fig. 7B, in both 5–8F and NPC/HK1 cells, compared to NPC’exo (1.12 ± 0.05 in 5‒8F cell, 1.14 ± 0.21 in NPC/HK1 cell; n = 3), the BAZ2A level was dramatically reduced in the NPC’exo+ mimic group (0.92 ± 0.01 in 5‒8F cell, 0.84 ± 0.09 in NPC/HK1 cell; n = 3), suggesting that BAZ2A was downregulated by the overexpression of miR-99a-5p. Here, BAZ2A is linked to nasopharyngeal carcinoma.
