Circulating endostatin is implicated in graft loss, but the role of local endostatin expression is unclear. Because of the anti-fibrotic and anti-angiogenic properties, we predicted decreased endostatin in renal proximal tubules to be associated with a higher risk of rejection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective study of 67 kidney allograft biopsies was performed, including zero-time (n = 11), non-rejection (n = 23), and rejection (n = 33) groups. Endostatin was quantitatively analyzed using immunohistochemistry on a 2-point scale. After adjustment for clinical and histological covariates, multivariate logistic regression was used to study the association of endostatin and rejection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Endostatin expression was highest in zero-time biopsies and significantly lower in rejection versus non-rejection cases (P &amp;lt; .001). Low endostatin expression was independently associated with rejection (adjusted OR = 7.47, 95% CI: 1.85\u201330.23, P = .005).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Reduced endostatin in proximal tubules is strongly associated with rejection.
