    6. Oxidants induce elevated cystatin C production from cardiac myocytes. Cystatin C plays a role in cardiac extracellular matrix remodelling. PMID: 20489058
    7. We found several novel glycoforms of cystatin c in rat hippocampal stem cells, suggesting that N- and O-linked glycans with sialic acid are attached to cystatin C. PMID: 15197734
    8. These results demonstrate that cystatin C has protective effects against various oxidative stresses that induce cell death. PMID: 16140167

    10. These studies suggest alternate pathways and potential therapeutic targets of cell death associated with oxidative stress, CC, and lysosomal dysregulation. PMID: 17241700
    11. Finally, in vivo studies using kidney-specific megalin knockout mice provide evidence that megalin mediates proximal tubular uptake of cystatin C. We conclude that megalin is an endocytic receptor of cystatin C in PTC. PMID: 17462596
