Additional file 7: Fig. S6. Effect of NOLC1 and TCOF1 knock-down on the nucleolar localization of FGF12 and its interaction with NOLC1 and TCOF1. HEK 293 cells were transfected with NOLC1/TCOF1-targeting siRNA or scramble siRNA (control). Fluorescence images of in situ PLA using a mixture of rabbit anti-FGF12 and mouse anti-NOLC1 or anti-TCOF1 antibodies. Cell nuclei were labeled with NucBlue Live and cells were analyzed with fluorescence microscopy. The dashed line indicates the cell area. The scale bar represents 20 μm
