Among these 75 tumor specimens, a high expression of ULBP4 in the adjacent normal nasopharyngeal epithelial tissues was found in 68% (51/75), whereas the expression in the corresponding cancer tissues was only in 26.7% (20/75) (χ2 = 25.7, P < 0.001) (Table 2). The gene discussed is RAET1E; the disease is cancer.
