DNM1L and nasopharyngeal carcinoma: In contrast, a high level of p-Drp1 (Ser637) in NPC patients correlated with a longer disease-free survival (n = 129, median survival time = 72 months vs. 66 months) and overall survival (n = 129, median survival time = 73 months vs. 69 months) than a low level of p-Drp1 (Ser637) according to results from a commercially available tissue microarray (Fig. 1f).
