Reef-building corals begin as non-calcifying larvae that, upon settling, rapidly begin to accrete skeleton and a protein-rich skeletal organic matrix that attach them to the reef. Here, we characterized the temporal and spatial expression pattern of a suite of biomineralization genes during three stages of larval development in the reef-building coral Pocillopora damicornis : stage I, newly released; stage II, oral-aborally compressed and stage III, settled and calcifying spat. Transcriptome analysis revealed 3882 differentially expressed genes that clustered into four distinctly different patterns of expression change across the three developmental stages. Immunolocalization analysis further reveals the spatial arrangement of coral acid-rich proteins (CARPs) in the overall architecture of the emerging skeleton. These results provide the first analysis of the timing of the biomineralization ‘toolkit’ in the early life history of a stony coral.

In Pregnancy

Pregnancy-associated glycoproteins (PAGs) are abundantly expressed products of the placenta of species within the Cetartiodactyla order (even-toed ungulates). They are restricted to this order and they are particularly numerous in the Bovidae. The PAGs exhibit a range of temporal and spatial expression patterns by the placental trophoblasts and probably represent a group of related proteins that perform a range of distinct functions in the epitheliochorial and synepitheliochorial placental forms. This review presents an overview of the origins of the PAGs, a summary of PAG expression patterns, and their use as markers of pregnancy status. Speculations about their putative role(s) in pregnancy are also presented.

Polypeptide Chains

The active form of platelet derived growth factor (PDGF) is a dimeric combination of two polypeptide chains: PDGF-A and PDGF-B. The protein can exist as a heterodimer (PDGF-AB) or as one of two homodimers (PDGF-AA, PDGF-BB), resulting in three isoforms. Two types of PDGF receptors also exist: PDGFRα and PDGFRß. The PDGFRß binds only the PDGF-B chain, while PDGFRα can bind both PDGF-A and -B chains. Both of these receptors show specific temporal and spatial expression patterns that are related to cellular responses including mitogenesis, cell migration, chemotaxis, adhesion and differentiation in a variety of cell types.Spontaneous mutants in which the PDGFRα is absent exhibit fatal defects during fetal development in mice. Some of these malformities include cardiac septal, valve, and outflow tract defects. Similar defects occur when the function of PDGF-A is disrupted by blocking antibodies. Disruption of PDGF-B function, results in ventricular and atrial dilation, hyper-trabeculation and reduction of the ventricular wall to the thickness of a single cell layer.
