PDLIM7 and nasopharyngeal carcinoma: Two sets of NPC cells, CNE1/CNE1‐LMP1 and HK1/HK1‐LMP1, were stained with TMRM and then observed by laser confocal microscopy to show that the fluorescence intensity of CNE1‐LMP1 and HK1‐LMP1 cells was significantly increased compared with CNE1 and HK1 parental cells (Fig 1A).
