Outline of Final Research Achievements |
Long-term peritoneal dialysis (PD) is associated with the development of functional and structural alterations of the peritoneal membrane, and is eventually limited by reduced efficacy. We have shown that high glucose concentrations inhibit FAK-mediated migration of mesothelial cells, and that dialysates containing high glucose concentrations cause peritoneal damage by inhibiting wound healing of the mesothelial cell monolayer. We also showed that an integrin-activating peptide, PHSRN, ameliorates inhibitory effects of conventional peritoneal dialysis fluids on peritoneal wound healing. We elucidated that PHSRN recoveres glucose-induced inhibition of cell motility and phosphorylation of focal adhesion kinase and its downstream p130Cas.
