Background and Methods: PCOS is common and associated with significant comorbidity. Yet, its pathogenesis is complex and poorly understood. We have developed new methods for deep phenotyping discovery proteomic profiling of urine to identify disease mechanisms and novel non-invasive biomarkers for PCOS in adolescents. We undertook proteomic analysis (nano 2D-LC-QTOF MSe) on a subset of 15 samples from a longitudinal PCOS cohort of 40 participants. We compared the ur...

Nephropathy remains a major diabetes related complication despite improvements in metabolic control. Current interventions are based on the appearance of albuminuria. Whether earlier detection and treatment might be beneficial is unclear. The reabsorption of low molecular weight (<70 kDa) plasma proteins in the renal proximal tubule is mediated by an endocytic receptor, megalin, and its coreceptor, cubulin.Using label free quantitative proteomics we ...
