Project description:Recent and ongoing studies evidence that certain LED lights, suitable for illuminating the urban fabric, avoiding primary colours such as blue, green, and red, may halt the biological colonization on stone monuments, mainly caused by algae and cyanobacteria forming subaerial biofilms (SABs). However, the light-triggered mechanisms that cause changes in the growth of the phototrophic species is so far unknown. An environmental proteomic approach could shed light on this aspect, providing information on the changes on SAB’s metabolism under the stress inflicted by different ornamental lighting. Here, laboratory-made SABs mainly composed of Chlorophyta, and at lesser extent Streptophyta and Cyanophyta, were subjected to three lighting conditions for monuments: cool white, warm white and, amber+green (with biostatic effect and under trial) A control without light (i.e., darkness) was also included for comparison. Cool white and warm white illumination severely affected SAB’s proteome reducing their total peptide identifications being the extent of this reduction dependent on the organisms’ genera. The photo-damaging effect of amber+green on the biofilm metabolism was clarified, revealing its negative impact on the photosystems I and II and antenna pigments production, and its triggering effect on the protein metabolism (synthesis, folding, and degradation). This research provides for the first-time a thorough description of the proteomic changes induced by lighting on SABs colonising illuminated monuments in urban areas. The insights gained will help to better design the lighting of monuments, with the inclusion of ornamental lighting as one of the elements to be taken into account in the preventive conservation of the built heritage.

Project description:We recently reported elimination of renal crystals and migration of macrophages (Mφ) around crystals in hyperoxaluric mice, suggesting Mφs might eliminate crystals. Mφs are of 2 phenotypes: inflammatory (M1) and anti-inflammatory (M2). Because M2Mφs are considered to be involved in tissue repair and regeneration, we focused attention on their suppressive role in renal crystal formation. Hence, we investigated the gene array profiling of renal macrophages in stone model mice and CSF-1-deficient stone model mice.

Project description:Kidney stone disease causes significant morbidity and increases health care utilization. In this dataset, we applied a single-nucleus assay to renal papila samples in order to charachterize the cellular and molecular niches in patients with calcium oxalate (CaOx) stone disease and healthy subjects. In addition to identifying cell types important in papillary physiology, we characterize collecting duct cell subtypes and an undifferentiated epithelial cell type that was more prevalent in stone patients. Despite the focal nature of mineral deposition in nephrolithiasis, we uncover a global injury signature characterized by immune activation, oxidative stress and extracellular matrix remodeling. We also identify the association of MMP7 and MMP9 expression with stone disease and mineral deposition, respectively. MMP7 and MMP9 are significantly increased in the urine of patients with CaOx stone disease, and their levels correlate with disease activity. Our results define the spatial molecular landscape and specific pathways contributing to stone-mediated injury in the human papilla and identify associated urinary biomarkers.

Project description:We recently reported elimination of renal crystals and migration of macrophages (MM-OM-^F) around crystals in hyperoxaluric mice, suggesting MM-OM-^Fs might eliminate crystals. MM-OM-^Fs are of 2 phenotypes: inflammatory (M1) and anti-inflammatory (M2). Because M2MM-OM-^Fs are considered to be involved in tissue repair and regeneration, we focused attention on their suppressive role in renal crystal formation. Hence, we investigated the gene array profiling of renal macrophages in stone model mice and CSF-1-deficient stone model mice. B6C3Fe a/a-Csf1op/J wild type/homozygous mice were admistered 80mg/kg gyyoxylate (GOX) for 6days, then the kidneys were extracted and sorted CD11b+/CD11c+ macrophages using autoMACS. The gene expression of WT- and op/op-macrophages were investigated using bone marrow derived M1/M2 macrophages as controls.
