Sabine Mazerbourg, Philippe Monget
The aim of the present article is to update our understanding of the expression of the insulin-like growth factor binding proteins (IGFBPs), IGFBP proteases and their implication in the different processes of ovarian folliculogenesis in mammals. In the studied species, IGFs and several small-molecular weight IGFBPs (in particular IGFBP-2 and IGFBP-4) are considered, respectively, as stimulators and inhibitors of follicular growth and maturation. IGFs play a key role in sensitizing ovarian granulosa cells to FSH action during terminal follicular growth...

BACKGROUND: N-terminal and C-terminal proteolytic fragments of IGF binding protein 4 (NT-IGFBP-4 and CT-IGFBP-4) were recently shown to predict adverse cardiac events in acute coronary syndrome (ACS) patients. NT-IGFBP-4 and CT-IGFBP-4 are products of the pregnancy-associated plasma protein-A (PAPP-A)-mediated cleavage of IGFBP-4. It has been demonstrated that circulating IGFBP-4 is partially glycosylated in its N-terminal region, although the influence of this glycosylation on PAPP-A-mediated proteolysis and the ratio of glycosylated/non-glycosylated IGFBP-4 fragments in human blood remain unrevealed...

The insulin-like growth factor (IGF) axis is required for the differentiation, development, and maintenance of bone tissue. Accordingly, dysregulation of this axis is associated with various skeletal pathologies including growth abnormalities and compromised bone structure. It is becoming increasingly apparent that the action of the IGF axis must be viewed holistically taking into account not just the actions of the growth factors and receptors, but also the influence of soluble high affinity IGF binding proteins (IGFBPs)...

OBJECTIVE: Isolated oligohydramnios is defined as an amniotic fluid index below five centimeter with no other coexisting condition. There are still controversies about the management and pregnancy outcomes. A marker predicting these is crucial. Low pregnancy associated plasma protein-A levels were reported to be related with adverse pregnancy outcomes. We aimed to determine the role of first trimester pregnancy associated plasma protein-A for poor outcomes in preterm isolated oligohydramnios cases...

BACKGROUND: The usage of Artificial Neural Networks (ANNs) for genome-enabled classifications and establishing genome-phenotype correlations have been investigated more extensively over the past few years. The reason for this is that ANNs are good approximates of complex functions, so classification can be performed without the need for explicitly defined input-output model. This engineering tool can be applied for optimization of existing methods for disease/syndrome classification. Cytogenetic and molecular analyses are the most frequent tests used in prenatal diagnostic for the early detection of Turner, Klinefelter, Patau, Edwards and Down syndrome...

Scarring is a consequence of biological tissue repair following trauma. Currently there are no generally agreed ways to prevent scarring. Recently, kynurenic acid has shown to be a potent modulator of extracellular matrix deposition and remodeling. Kynurenic acid can reduce matrix deposition and other fundamental characteristics of fibrosis in vitro and in vivo. Specifically, kynurenic acid has shown to increase MMP-1 activity and subsequently reduce collagen deposition in a rabbit ear scar model. In the current study kynurenic acid cream in different concentrations was topically applied on healthy skin on volunteers to assess skin reactions and skin sensitivity in both acute and chronic application settings...

INTRODUCTION: Pregnancy-associated plasma protein-A (PAPP-A) stimulates insulin-like growth factor (IGF)-I action through proteolytic cleavage of IGF binding protein-4 (IGFBP-4). Recently, stanniocalcin-2 (STC2) was discovered as an inhibitor of PAPP-A. Most members of the IGF system are expressed in adipose tissue (AT), but there is a relative paucity of information on the distribution of IGFBP-4, PAPP-A, and STC2 in different AT depots. Since IGF-I expression in AT is highly GH-dependent, we used bovine GH transgenic (bGH) and GH receptor knockout (GHR-/-) mice to investigate AT depot-specific expression patterns of IGFBP-4, PAPP-A, and STC2, and whether the regulation is GH-dependent...
