Microglial cells were harvested and maintained in the 96-well plate, with <t>DMEM-F12</t> containing 2% <t>FBS</t> at least for 2 h for the return of a resting state. After treated with the indicated concentration of Aβ for the indicated time, microglia cells were rinsed with live cell imaging solution. Intracellular pH of microglia was detected using fluorescent dye-based pHrodo Red AM intracellular pH indicator. The wavelength of 560 and 580 nm fluorescent light for excitation and emission was used in a Gemini EM microtiter plate reader. Forskolin (100 μM), a powerful protein kinase A (PKA) activator, capable of enhancing lysosomal acidification in intact cell, was served as control. Intracellular pH values were determined by the value of the arbitrary pH ratios of light excited at 560 nm and emitted at 580 nm with pH calibration curve kit (Invitrogen).

TEM images of Ag NPs after 7 days incubation in PBS ( a ), PBS supplemented with 1% FBS ( b ) and PBS supplemented with L -cysteine and L -methionine at the same concentrations of amino acids as those found in RPMI-1640 ( c ) and corresponding EDS spectra ( d ); TEM images and corresponding EDS spectra (insets) of Ag NPs after 7 days incubation in RPMI-1640 supplemented with 1% FBS, with initial silver concentrations of 2 μg ml −1 ( e ), 10 μg ml −1 (f) and 100 μg ml −1 ( g ), with elemental mapping images provided in Supplementary Fig. 26 . Scale bars are 100 nm ( a – c ) or 50 nm ( e – g ).

    Corona-mediated sulphidation of Ag NPs impacts particle toxicity. TEM images of partially sulphidated Ag NPs after pre-incubation in RPMI-1640 with 10% FBS ( a ) and completely sulphidated Ag NPs after pre-incubation in RPMI-1640 with 1% FBS ( b ); scale bars are 50 nm; Viability of J774 murine macrophages (as measured with MTT assays) after 24 h exposure to various concentrations (2, 5, 10, 15, 25, 50 and 100 μg ml −1 ) of Ag + ions (black diamonds), pristine Ag NPs (red triangles), partially sulphidated Ag NPs (blue squares) and completely sulphidated Ag NPs (orange circles); error bars are provided as standard deviation; statistically significant differences (two-tailed t -test, with all data sets showing normal distribution and similar variance values) as compared with the control are marked with ** P

    KSRP overexpression effects β-catenin signaling in colon carcinoma cells. SW480 cells (2.5×10 5 cells/well in a 12-well cell culture dish) were transfected with indicated amounts of either empty vector or FLAG-KSRP plasmid for 24 hours using a Fugene transfection reagent (Roche applied life sciences) to DNA ratio of 5:2. The lysates were then assayed either for cytosolic β-catenin levels ( A ) or Lef/Tcf-sensitive transcription ( B ). Upper panel in B displays mean values ± s.e.m. obtained from three independent experiments; the lower panel displays representative blots. For the β-catenin assay representative blots of two independent experiments that proved highly reproducible are displayed. ## P
