Soluble and insoluble TPC6A aggregates are present in the hippocampi of nondemented human controls and AD samples (A) Frozen postmortem AD and control human hippocampal tissues were homogenized by sonication. After centrifugation, the insoluble pellets were further extracted and analyzed by filter retardation assay. Western blotting was then carried out using specific antibodies for TPC6A (pan-specific), TIAF1, Tyr33-phosphorylated WWOX (p-WWOX), NFT and Aß. No significant difference was shown in TPC6A or TIAF1 aggregation for samples between younger nondemented controls (14 samples per group; total 3 groups; 42 to 76 years old) and older AD patients (24 samples per group; total 4 groups; 71 to 90 years old). C = control; A or AD = Alzheimer's disease. (B) The supernatants of the aforementioned samples were analyzed by 7% non-reducing SDS-PAGE. Western blotting analyses show the presence of soluble aggregates of TPC6A and Aß in the representative protein preparations. Sample numbers are shown in each panel. Molecular weight markers: 170, 130, 95, 72 kDa. (C) Hippocampal tissue sections of APP/PS1-transgenic mice were stained with aliquots of TPC6A pan-specific antiserum and then with an Alexa Fluor 488-conjugated secondary antibody. Fluoro-Jade C was used for staining degenerative neurons, and nuclei stained with DAPI. TPC6A aggregates are localized in the degenerative neurons. A representative tissue section is shown. Scale bar: 50 µm. In negative controls, the sections were stained with the secondary antibody only, followed by staining with Fluoro-Jade C and DAPI. (D) Immuno-intensity was measured and normalized to negative controls (mean ± standard deviation, n = 5; **p < 0.05, student's t test).
