Examination of the localization and expression levels of LMP1 protein in nasopharyngeal mucosa specimens showed that the LMP1 protein expression rate in nasopharyngeal carcinoma was 73.8% and that in nasopharyngitis tissue was 22.7% (p < 0.01), respectively (Table 1). This evidence concerns the gene PDLIM7 and nasopharyngeal carcinoma.
