EMT in BSA-induced damaged tubule was associated with increased levels of DPP-4, integrin beta1 and CAV1; TENE treatment ameliorated these alterations. (a–e) Multiplex immunofluorescence microscopy analysis of the EMT program and association with CAV1. Formaldehyde-fixed, paraffin-embedded (FFPE) kidney samples were labeled with epithelial markers for E-cadherin, alphaSMA and CAV1. An immunofluorescence analysis was performed by confocal microscopy. (d) The enlarged image of the inset shown in (c). The alphaSMA-positive damaged tubular cells were surrounded by alphaSMA-positive interstitial cells (f–j). Multiplex immunofluorescence was performed to analyze the crosstalk among DPP-4, integrin beta1 and CAV1 in the BSA-injected diabetic mice. (i) The enlarged image of the inset shown in (h). DPP-4, integrin beta1, and CAV1 were localized at the same location (likely the luminal side of the proximal tubule). The crosstalk occurred more frequently in the damaged tubular cells.

Alteration of the size of lysosomes and the expression of LAMP-1 in in Rab7 deltapan pancreatic acinar cells. (a–d) Immunofluorescence images of wild (a,c) and Rab7 deltapan (b,d) pancreases stained with anti-LAMP1(a,b) or anti-cathepsin B (c,d) antibodies (red). DAPI was used for nuclear staining (blue). Bars: 20 µm. (e) Quantification of the positive signals in immunofluorescence images of LAMP-1 (left panel) and cathepsin B (right panel). *P < 0.05. (f) WB of LAMP-1 using total pancreas homogenate of wild and Rab7 deltapan mice. An antibody against LAMP-1 N-terminal (top panel) and an antibody against LAMP-1 C-terminal (middle panel) were utilized. Anti-LAMP-1 N-terminal antibody revealed the shifting of intense bands to a lower position (top panel, arrow head) than that of full-length LAMP-1 (120 kDa) in Rab7 deltapan pancreas. In contrast, anti-LAMP-1 C-terminal antibody revealed bands at 120 kDa only in both wild and Rab7 deltapan pancreas (middle panel). beta-actin was used as an internal loading control (bottom panel).
