Differential expression analysis and LASSO regression identified CAM biomarkers in a discovery cohort, followed by ELISA validation in an independent, discovery cohort. Biomarker correlations with clinicopathological parameters were assessed, and receiver operating characteristic (ROC) analyses were performed to examine the potential diagnostic utility.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of the 17 CAMs analyzed, serum NrCAM and P-Cadherin emerged as the most promising new biomarkers, significantly discriminating LN from HC.

In a larger validation cohort, ROC analyses demonstrated strong diagnostic potential for both biomarkers, with AUC values of 0.92 and 0.82 for serum NrCAM and P-Cadherin, respectively. Significant correlations with SLEDAI, rSLEDAI, and histological indices further underscored their potential relevance to LN severity and activity. Interestingly, serum NrCAM and P-Cadherin are complementary in reflecting renal pathology changes including endocapillary hypercellularity, cellular crescents, glomerulosclerosis, tubular atrophy, and interstitial fibrosis.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Serum NrCAM and P-Cadherin show promise as non-invasive biomarkers for LN, offering potential utility in diagnosis and disease monitoring.
