Expression data from kidney biopsies of liver disease patients

ABSTRACT: Glomerular abnormalities have been demonstrated in kidney biopsies of patient after orthotopic liver transplantation (OLT). We hypothesize that these changes exist prior to OLT and may play a role in the development of renal failure after OLT. We use gene expression microarrays to investigate the mechanism of kidney disease in patients listed for OLT. Gene expression profiles of biopsies of cirrhotic patients were compared with pre-implantation living donor biopsies. Glomerular abnormalities were seen in 92% of the biopsies, the most common being increase in mesangial matrix. Electron microscope showed effacement of podocytes (93%) and duplication (35%) and widening of glomerular basement membrane (45%). Gene Ontology analysis revealed significant up-regulation of genes implicated in immun
