SATB1 and nasopharyngeal carcinoma: In the present study, our preliminary data revealed that LMP1 expression was positively associated with SATB1 expression in clinical NPC specimens (r = 2.35, P < 0.01); in addition, the expression level of SATB1 was correlation with LMP-1 expression status in NPC cell lines (Figure 7); much interestingly, ectopic expression of LMP-1 strongly promoted SATB1 expression and its nuclear location, as well as an up-regulation of PCNA, in well-differentiated CNE1 cells (Figure 8).
