--- _id: '6352' abstract: - lang: eng text: Chronic overuse of common pharmaceuticals, e.g. acetaminophen (paracetamol), often leads to the development of acute liver failure (ALF). This study aimed to elucidate the effect of cultured mesenchymal stem cells (MSCs) proteome on the onset of liver damage and regeneration dynamics in animals with ALF induced by acetaminophen, to test the liver protective efficacy of MSCs proteome depending on the oxygen tension in cell culture, and to blueprint protein components responsible for the effect. Protein compositions prepared from MSCs cultured in mild hypoxic (5% and 10% O2) and normal (21% O2) conditions were used to treat ALF induced in mice by injection of acetaminophen. To test the effect of reduced oxygen tension in cell culture on resulting MSCs proteome content we applied a combination of high performance liquid chromatography and mass-spectrometry (LC–MS/MS) for the identification of proteins in lysates of MSCs cultured at different O2 levels. The treatment of acetaminophen-administered animals with proteins released from cultured MSCs resulted in the inhibition of inflammatory reactions in damaged liver; the area of hepatocyte necrosis being reduced in the first 24 h. Compositions obtained from MSCs cultured at lower O2 level were shown to be more potent than a composition prepared from normoxic cells. A comparative characterization of protein pattern and identification of individual components done by a cytokine assay and proteomics analysis of protein compositions revealed that even moderate hypoxia produces discrete changes in the expression of various subsets of proteins responsible for intracellular respiration and cell signaling. The application of proteins prepared from MSCs grown in vitro at reduced oxygen tension significantly accelerates healing process in damaged liver tissue. The proteomics data obtained for different preparations offer new information about the potential candidates in the MSCs protein repertoire sensitive to oxygen tension in culture medium, which can be involved in the generalized mechanisms the cells use to respond to acute liver failure. acknowledgement: The studies were supported by the Austrian Federal Ministry of Economy, Family and Youth through the initiative “Laura Bassi Centres of Expertise” funding the Center of Optimized Structural Stud-ies, grant No. 253275 article_processing_charge: Yes (via OA deal) author: - first_name: Andrey Alexandrovich full_name: Temnov, Andrey Alexandrovich last_name: Temnov - first_name: Konstantin Arkadevich full_name: Rogov, Konstantin Arkadevich last_name: Rogov - first_name: Alla Nikolaevna full_name: Sklifas, Alla Nikolaevna last_name: Sklifas - first_name: Elena Valerievna full_name: Klychnikova, Elena Valerievna last_name: Klychnikova - first_name: Markus full_name: Hartl, Markus last_name: Hartl - first_name: Kristina full_name: Djinovic-Carugo, Kristina last_name: Djinovic-Carugo - first_name: Alexej full_name: Charnagalov, Alexej id: 49F06DBA-F248-11E8-B48F-1D18A9856A87 last_name: Charnagalov citation: ama: Temnov AA, Rogov KA, Sklifas AN, et al.
