Project description:We catalogued and quantified the transcripts in livers of wild-type and Aag-deficient mice that had been exposed to the model alkylating agent methyl methanesulfonate (MMS). Gene expression analysis was performed for samples harvested 6 hours post-MMS treatment.
Project description:We analyzed the proteomic changes that occur in a Fbxl4 knock-out 1-year mouse. We analyzed Liver tissue using a 6-plex TMT approach (3 KO and 3 controls). Since we observed a global decrease in mitochondrial proteins, we also explored mitoproteome changes in different tissues (liver, kidney and heart) using a label-free approach. Finally, we also did a 6-plex TMT to analize the proteomic changes in 3 patient-derived fibroblast lines compared to 3 control lines and correlated them with the results obtained in the mouse model. All together, these experiments revealed that Fbxl4 deficiency leads to a decreased mitochondrial content without major changes in mitochondria itself, pointing to an increased turnover.
Project description:Transcriptional profile of stress in fission yeast (S. pombe) cells. Five different types of stress were employed on wild type and mutant cells (sty1 and atf1 knock-out cells). The 5 stresses were heat, and four types of compound: heavy metal, oxidation, alkylation and osmosis.
Project description:The cell-specific role of lysosomal protease cathepsin D (CtsD) in liver fibrosis is not completely clear. This study reports that while CtsD is highly expressed in liver macrophages of cirrhotic patients, CtsD deletion in macrophages resulted in enhanced liver fibrosis. For this scope, a macrophage-CtsD knock-out mouse (CtsDMac) model was generated. Livers obtained from the mouse model and from its control were analyzed by shotgun label-free quantitative (LFQ) proteomics.
