The immunofluorescence staining was performed on OE19 and JHESO EAC cells treated with PVT1 ASO at 1 μM as performed as previously described [18 (link)]. Expression and localization of the proteins were observed under a confocal microscope system (FluoView FV500; Olympus) and analyzed by CellQuest PRO software (BD Biosciences, San Jose, CA). Information for antibodies used in immunofluorescent staining and western blot was described in Additional file 6: Figure S6.
