Progranulin deficiency is associated with neurodegeneration in humans and in mice. The mechanisms likely involve progranulin-promoted removal of protein waste via autophagy. We performed a deep proteomic screen of the pre-frontal cortex in aged (13-15 months) female progranulin-deficient mice (GRN) and mice with inducible neuron-specific overexpression of progranulin (SLICK-GRN-OE) versus the respective control mice. Proteins were extracted and analyzed per liquid chromatography/mass spectrometry (LC/MS) on a Thermo Scientific™ Q Exactive Plus equipped with an ultra-high performance liquid chromatography unit and a Nanospray Flex Ion-Source. Full Scan MS-data were acquired using Xcalibur and raw files were analyzed using the proteomics software Max Quant. The mouse reference proteome set from uniprot (June 2015) was used to identify peptides and proteins. The DiB data file is a reduced MaxQuant output and includes peptide and protein identification, accession numbers, protein and gene names, sequence coverage and label free quantification (LFQ) values of each sample. Differences in protein expression in genotypes are presented in "Progranulin overexpression in sensory neurons attenuates neuropathic pain in mice: Role of autophagy" (C. Altmann, S. Hardt, C.

颗粒蛋白前体缺乏与人类和小鼠的神经退行性变有关。其机制可能涉及颗粒蛋白前体通过自噬促进蛋白质废物的清除。我们对老年(13 - 15个月)雌性颗粒蛋白前体缺陷小鼠(GRN)和颗粒蛋白前体可诱导神经元特异性过表达的小鼠(SLICK - GRN - OE)以及各自的对照小鼠的前额叶皮层进行了深度蛋白质组学筛查。通过配备超高效液相色谱单元和纳喷雾Flex离子源的Thermo Scientific™ Q Exactive Plus,根据液相色谱/质谱(LC/MS)提取并分析蛋白质。使用Xcalibur采集全扫描质谱数据,并使用蛋白质组学软件Max Quant分析原始文件。使用来自uniprot(2015年6月)的小鼠参考蛋白质组集来鉴定肽段和蛋白质。DiB数据文件是简化的MaxQuant输出,包括每个样本的肽段和蛋白质鉴定、登录号、蛋白质和基因名称、序列覆盖率以及无标记定量(LFQ)值。基因型中蛋白质表达的差异在“感觉神经元中颗粒蛋白前体过表达减轻小鼠神经性疼痛:自噬的作用”(C. 阿尔特曼、S. 哈特、C. 菲舍尔、J. 海德勒、H.Y. 林、A. 豪斯勒、B. 阿尔伯克基、B. 齐默尔、C. 莫泽、C. 贝伦兹、F. 肯特根、I. 维蒂希、M.H. 施密特、A.M. 克莱门特、T. 德勒、I. 特格德,2016年)[1]中有阐述。
