The result showed that sixty-one mRNAs, such as PCNA, TIGAR, MMP1, FN1, SPARC and POSTN, upregulated in the CNE2 cells were also upregulated in NPC tissues; seventy-six mRNAs, such as CDKN2B, BCL6, KLF4 and TP53INP2, downregulated in the CNE2 cells were also downregulated in NPC tissues (Figure 5E, Supplementary Table S3), which suggests that these DEGs regulated by heterozygous p53-R280T mutation maybe participate in the carcinogenesis of NPC. Here, POSTN is linked to nasopharyngeal carcinoma.
