  1. Systemic rAAV-DCN in neuroblastoma-grafted nude mice inhibited stabilin-1. PMID: 28631095

It is then possible that this proteoglycan excess may interfere with normal endometrial hemostasis in PCOS. PMID: 28789706

  9. A Finnish cohort of 336 subjects with diagnosed hypertension and 444 controls was analyzed. Samples were genotyped for decorin rs7308752 and rs516115 polymorphisms. The GG genotype of the decorin polymorphism rs7308752 (A>G) and the CC genotype of the rs516115 (T>C) are associated with decreased plasma resistin levels. These two decorin polymorphisms appear to have biological relevance in human vascular pathophysiology. PMID: 27315044
