Dissection of ventral pial cerebral vessels: Mice were anesthetized with Ketamine (100 mg/kg) and Xylazine (10 mg/kg) and transcardially perfused with 20 ml PBS, followed by 2 ml of 2% Evan’s blue (w/v) prepared in PBS. After brain harvest, pial vessels were collected from the ventral face of the brain with micro forceps under a M205 A dissection microscope (Leica) and snap frozen on dry ice. Lysis of cerebral vessels. Vessels were mixed with 4% (w/v) SDS, 100 mM dithiothreitol, 100 mM Tris–HCl, ...

Comparative small RNA expression profiling analysis for four transgenic mouse models ( C9orf72, SOD1, TDP-43 and FUS) of ALS with each 5 males/females and 5 case/control samples. For FUS one male control sample was excluded.

Comparative gene expression profiling analysis of RNA-seq data for four transgenic mouse models ( C9orf72, SOD1, TDP-43 and FUS) of ALS with each 5 males/females and 5 case/control samples. For FUS one male control sample was excluded.

3-4 months old male and female C57BL/6J mice (n=10 intact controls, n=10 SW-injured, n=5 LPS injected) were sacrificed through cervical dislocation, brains were removed and placed into cold PBS. Biopsy punches (2.5 mm diameter) of the visual cortex of both hemispheres were dissected whereas meninges and white matter were carefully taken off. The contralateral (uninjured) cortices of the SW-injured brains were not considered for proteome analysis (intact: n=20, SW: n=10, LPS: n=10). Samples were ...

8 months old control C57BL/6J (n=10), 17 months aged C57BL/6J (n=4), and 8 months old APP/PS1 mice (n=5) were sacrificed through cervical dislocation, brains were removed and placed into cold 1x PBS. Biopsy punches of the visual cortex of both hemispheres were taken with a tissue puncher (2.5 mm diameter) and meninges and white matter were carefully removed using forceps to have a tissue sample consisting of grey matter only. Each sample was put into a low-protein binding Eppendorf tube, frozen ...

Per sample 10μg of isolated mitochondria were used. SDS was added to a final concentration of 2% for efficient solubilization, prior to tryptic protein digest using a modified FASP protocol (Wiśniewski et al., 2009). Proteomic measurements were performed on a Q-Exactive HF mass spectrometer (Thermo Scientific) online coupled to an Ultimate 3000 nano-RSLC (Dionex). Peptides were separated on a C18 nanoEase MZ HSS T3 column (100Å, 1.8 µm, 75 µm x 250 mm; Waters) in a 95 min non-linear acetonitrile ...

Nuclear extracts of cells expressing Trnp1, FLAGTrnp1, delta1-16Trnp1 or FLAGdelta1-16Trnp1 were obtained by re-suspended cells for 30 min on ice in Tween20 lysis buffer (25 mM HEPES pH 8, 20 mM NaCl, 2 mM EDTA, 1 mM PMSF, 0.5% Tween20, 1X protease inhibitors, cOmplete, Roche), pelleted nuclei by centrifugation, discarding the cytoplasmic fraction (supernatant) and lysing nuclei by sonication with lysis buffer containing 500 mM NaCl. DNAseI (250U; SIGMA) was added to the nuclear pellet and incubated ...
