(A) Representative immunohistochemical (IHC) analysis of human PDAC tissues. The areas marked by the squares were further magnified. Scale bars, 25 μm.
(B) Representative IHC of non-tumor (NT) and tumor (T) areas in IKKαhigh (patient #5) and IKKαlow (patient #6) human PDAC specimens. Marked areas were examined under higher magnification. Scale bars, 25 μm.
(C) Imaging and quantification (on the bottom) of LC3 puncta and LC3-LAMP1 co-localization in above specimens. Mean ± SEM (n=10 patients). Statistical significance was determined by a 2-tailed t-test; ***p < 0.001. Scale bars, 10 μm
(D) Representative images and MP quantification (on the right) in TMR-DEX injected fresh surgical specimens from patients #5 (IKKαhigh;NRF2low tumor) and #6 (IKKαlow;NRF2high tumor). PEC or carcinoma cells are marked by E-cadherin staining. Scale bar, 20 μm. Mean ± SEM (n=10). ****p < 0.0001.
