Nano-LC-MS/MS proteomics in amniotic fluid from CAKUT patients

The objective of the present work was to identify new renal proteins responsible for Congenital Anomalies of the Kidney and of the Urinary Tract (CAKUT pathophysiology). We conducted a comparative LC-MS/MS-based proteomics analysis of amniotic fluids (AF) collected from non-severe CAKUT (ns-CAKUT; n=19), severe CAKUT (s-CAKUT; n=14), and healthy controls (cont; n=22) fetuses. We identified a total of 224 gestational age independent proteins that were significantly different in abundance when comparing (one-way ANOVA corrected p<0.05) the 3 groups of amniotic fluids 2 by 2. We identified 8 gestational-age independent proteins that were in common when comparing the 3 groups two by two, and that were considered as associated to both CAKUT onset and CAKUT severity.
