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).

GF-ß1 induces TPC6A? aggregation for leading to caspase activation (A) Neuroblastoma SK-N-SH cells were transiently expressed with ECFP or ECFP-TPC6A? and treated with TGF-ß1 (5 ng/ml) for indicated times, followed by fixation, permeabilization and staining with Aß antibody. The ratios of the expression of Aß to TPC6A? are shown (n = 5). (B) TPC6A aggregates (green) are present in the mitochondria of degenerative neurons in the AD hippocampus. Tissue sections were pre-stained with the Bielschowsky stain (brown to dark), and then stained with Fluoro-Jade C Red for degenerative neurons (red), specific COX4 antibody for mitochondria (cyan), DAPI for nuclei (blue) and pan-specific antibody for TPC6A (green). 600x magnification; Scale bar: 10 µm. (C) In negative controls, no primary antibody was used in the immunostaining. (D) Transiently overexpressed EYFP-TPC6A? was aggregated in SK-N-SH cells, and caspase 3 became activated (Casp3*). (E) No caspase 3 activation was observed, if ectopic TPC6A? was not aggregated. (F) TGF-ß1 increased TPC6A? aggregation and caspase 3 activation. (G–H) Wild type TPC6A (TPC6Awt), either in a native or an aggregated state, did not induce caspase 3 activation. (I–J) SK-N-SH cells were transiently overexpressed with the indicated expression constructs. The number of cells harboring protein aggregation was counted, and the extent of caspase 3 activation was measured (n = 3; Student's t tests; ~50 cells counted per experiment). (K) Colocalization of S35-phosphorylated TPC6A? with activated caspase 3 in the AD hippocampal tissue sections. A representative data is shown.
