Firstly, the potential induction of NF-κB was visualized via the fluorescent localization of the RELA protein (exemplary images for PXIII in Figure 8B, and PIX, PXI and PXIV PCSCs in Figure S12) given that the simultaneous regulation of nuclear RELA translocation and overall NF-κB activation in cancer cells has already been reported [62]. Here, RELA is linked to cancer.
