Proteasome-dependent degradation of intracellular carbamylated proteins

Figure 1. Evidence for the presence of carbamylated proteins inside human skin cells. An anti-HCit immunolabelling was realized in a skin section from a 77-year old man counter-stained with DAPI and hematoxylin-eosin. Epidermal area was screened by light microscopy thanks to hematoxylin-eosin counterstaining (a). Nuclei were highlighted by DAPI staining (b, blue) permitting confirmation of the presence of HCit inside skin cells by immunofluorescence analysis (c, green). An example of a cell exhibiting a positive intracellular labelling for HCit is indicated by arrows. Observations were realized at 10x magnification.
