The results showed that MARK1, PGAP1, and KITLG expression was upregulated in NPC cell lines relative to the normal human nasopharynx cell line (Figure 11(e-g)), while CRIP1 expression was downregulated in NPC cell lines relative to normal human nasopharynx cell lines (Figure 11h). Here, PGAP1 is linked to nasopharyngeal carcinoma.
