In this study, Caco-2 permeability results from different laboratories were compared. Six different sets of apparent permeability coefficient (Papp) values reported in the literature were compared to experimental Papp obtained in our laboratory. The differences were assessed by determining the root mean square error (RMSE) values between the datasets, which reached levels as high as 0.581 for t...

BACKGROUND We previously reported that the degradation of prohibitin by the SCF(Skp2B) ubiquitin ligase results in a defect in the activity of p53. We also reported that MMTV-Skp2B transgenic mice develop mammary gland tumors that are characterized by an increased proteolytic cleavage of the insulin-like growth factor binding protein 4 (IGFBP-4), an inhibitor of IGF signaling. However, whether ...

INTRODUCTION Abnormalities in maternal serum marker levels and fetal measurements obtained during the first trimester screening can be a marker not only for certain chromosomal disorders and anomalies in the fetus but also for specific pregnancy complications. In particular, low maternal serum pregnancy-associated plasma protein-A (PAPP-A), at 11-13 weeks of gestation, is associated with stillb...

A full-length cDNA encoding a novel human protein was cloned from placenta cDNA. The corresponding 1542 amino acid protein sequence was termed `pregnancy-associated plasma protein-E' (PAPP-E) as it shows a 62% homology to the human pregnancy-associated plasma protein-A (PAPP-A) that is a diagnostic marker for trisomies, especially Down syndrome. The conserved domain structure contains five moti...

Type 2 diabetes mellitus is associated with increased inflammation and accelerated atherosclerosis. The association of the pro-inflammatory and potentially pro-atherosclerotic molecule, pregnancy associated plasma protein-A (PAPP-A) with diabetes and vascular diseases remains to be further established. A total of 107 patients with type 2 diabetes and 101 healthy controls participated in this st...

The pregnancy-associated plasma protein-A knockout (PAPP-A KO) mouse is a model of reduced local insulin-like growth factor (IGF)-I activity with normal circulating IGF-I levels. In this study, PAPP-A KO mice had significantly increased mean (27%), median (27%), and maximum (35%) life span compared with wild-type (WT) littermates. End-of-life pathology indicated that the incidence of neoplastic...

Amaç: Plasenta previa (PP) tanılı olgularda plasenta akreta indeks (PAI) skoru ile ilk trimester serum belirteçlerinin (PAPP-A, serbest β HCG) Akreta Spektrumu (PAS) öngörüsündeki yerini araştırmayı amaçladık.
 Gereç ve Yöntemler: Çalışmamıza 30 PAS, adezyon anomalisi saptanmayan olgusu 60 sağlıklı gebe dahil edildi. Çalışmaya edilen olguların, üçüncü trimesterda PAI belirlendi, ardından b...

OBJECTIVE The proteolytic activity of metalloproteinases, proinflammatory enzymes that degrade extracellular matrix, is elevated in lipid-rich atherosclerotic plaques, thereby contributing to plaque fragility and rupture. Pregnancy-associated plasma protein (PAPP-A) is a metalloproteinase, expressed in unstable atherosclerotic plaques, whose circulating levels are elevated in acute coronary syn...

OBJECTIVE The aim of this study was to investigate the association of the first trimester screening variables nuchal translucency (NT), pregnancy associated plasma protein (PAPP-A), and free beta-human chorionic gonadotrophin (βhCG) and birth weight, with a focus on the prediction of macrosomia. METHODS The database of our Fetal Medicine Unit was searched for all singleton pregnancies, who un...
