Proteomic-based detection of a protein cluster dysregulated during cardiovascular development identifies biomarkers of congenital heart defects
BACKGROUND: Cardiovascular development is vital for embryonic survival and growth. Early gestation embryo loss or malformation has been linked to yolk sac vasculopathy and congenital heart defects (CHDs). However, the molecular pathways that underlie these structural defects in humans remain largely unknown hindering the development of molecular-based diagnostic tools and novel therapies. METHODOLOGY/PRINCIPAL FINDINGS: Murine embryos were exposed to high glucose, a condition known to induce cardiovascular defects in both animal models and humans. We further employed a mass spectrometry-based proteomics approach to identify proteins differentially expressed in embryos with defects from those with normal cardiovascular development. The proteins detected by mass spectrometry (WNT16, ST14, Pcsk1, Jumonji, Morca2a, TRPC5, and others) were validated by Western blotting and immunoflorescent staining of the yolk sac and heart. The proteins within the proteomic dataset clustered to adhesion/migration, differentiation, transport, and insulin signaling pathways. A functional role for several proteins (WNT16, ADAM15 and NOGO-A/B) was demonstrated in an ex vivo model of heart development. Additionally, a successful application of a cluster of protein biomarkers (WNT16, ST14 and Pcsk1) as a prenatal screen for CHDs was confirmed in a study of human amniotic fluid (AF) samples from women carrying normal fetuses and those with CHDs. CONCLUSIONS/SIGNIFICANCE: The novel finding that WNT16, ST14 and Pcsk1 protein levels increase in fetuses with CHDs suggests that these proteins may play a role in the etiology of human CHDs. The information gained through this bed-side to bench translational approach contributes to a more complete understanding of the protein pathways dysregulated during cardiovascular development and provides novel avenues for diagnostic and therapeutic interventions, beneficial to fetuses at risk for CHDs

Olive Genetic Resources
UMR AGAP - équipe AFEF - Architecture et fonctionnement des espèces fruitièresAs one of the most important and ancient fruit crops in the Mediterranean Basin, olive is characterized by a huge genetic patrimony, represented by cultivated and wild germplasm, ancient trees and related forms. The richness of this germplasm represents an unusual case among horticultural crops, due to species longevity, lack of new better performing genotypes, and the millennial tradition of cultivation. Focusing on a wide spectrum of genetic resources, their conservation, characterization, and management, this chapter tries to give an insight into the achievements and the necessities of this type of works in olive. Knowledge of existing diversity among the olive genetic resources is essential to maximize their conservation, safeguard, and exploitation
