The 7 TM G‐Protein‐Coupled Receptor Target Family
Authors: Jacoby Edgar , Bouhelal Rochdi , Gerspacher Marc , Seuwen Klaus
Published: August 2006

Chemical biology approaches have a long history in the exploration of the G‐protein‐coupled receptor (GPCR) family, which represents the largest and most important group of targets for therapeutics. The analysis of the human genome revealed a significant number of new members with unknown physiological function which are today the focus of many reverse pharmacology drug‐discovery programs. As the seven hydrophobic transmembrane segments are a defining common structural feature of these receptors, and as signaling through heterotrimeric G proteins is not demonstrated in all cases, these proteins are also referred to as seven transmembrane (7 TM) or serpentine receptors. This review summarizes important historic milestones of GPCR research, from the beginning, when pharmacology was mainly descriptive, to the age of modern molecular biology, with the cloning of the first receptor and now the availability of the entire human GPCR repertoire at the sequence and protein level. It shows how GPCR‐directed drug discovery was initially based on the careful testing of a few specifically made chemical compounds and is today pursued with modern drug‐discovery approaches, including combinatorial library design, structural biology, molecular informatics, and advanced screening technologies for the identification of new compounds that activate or inhibit GPCRs specifically. Such compounds, in conjunction with other new technologies, allow us to study the role of receptors in physiology and medicine, and will hopefully result in novel therapies. We also outline how basic research on the signaling and regulatory mechanisms of GPCRs is advancing, leading to the discovery of new GPCR‐interacting proteins and thus opening new perspectives for drug development. Practical examples from GPCR expression studies, HTS (high‐throughput screening), and the design of monoamine‐related GPCR‐focused combinatorial libraries illustrate ongoing GPCR chemical biology research. Finally, we outline future progress that may relate today’s discoveries to the development of new medicines.
Balancing the bipotential gonad between alternative organ fates: A new perspective on an old problem
Authors: Kim Yuna , Capel Blanche
Published: August 2006

The embryonic gonads give rise to one of two morphologically and functionally different organs, a testis or an ovary. Sex determination is the embryonic process that determines the developmental fate of the gonad. In mammals, sex determination is regulated by a DNA binding protein encoded on the Y chromosome, Sry, and it's downstream mediator, Sox9, which trigger testis determination in the bipotential gonad. However, evidence suggests that the extracellular signals. Fgf9 and Wnt4, are also required to establish divergent organogenesis of the gonad. In this review, we discuss how these extracellular signals interface with cell‐autonomous factors to determine the fate of the mammalian gonad, and we derive a model that could provide a molecular explanation for testis determination in vertebrates where Sry is absent.

Cloning of vertebrate Protogenin (Prtg) and comparative expression analysis during axis elongation
Authors: Vesque Christine , Anselme Isabelle , Couvé Elisabeth , Charnay Patrick , Schneider‐Maunoury Sylvie
Published: August 2006

A murine cDNA encoding Protogenin, which belongs to the DCC/Neogenin family, was cloned in a screen performed to identify novel cDNAs regionally expressed in the neural plate. Isolation of the putative zebrafish orthologues allowed a comparative analysis of the expression patterns of Protogenin genes during embryogenesis in different vertebrate species. From mid‐gastrulation to early somite stages, Protogenin expression is restricted to posterior neural plate and mesoderm, with an anterior limit at the level of the rhombencephalon in mouse, chicken, and zebrafish. During somitogenesis, the expression profiles in the three species share features in the neural tube but present also species‐specific characteristics. The initiation of Protogenin expression just before somitogenesis and its maintenance in the neural tube and paraxial mesoderm during this process suggest a conserved role in axis elongation.

Emerging developmental model systems
Authors: Kiefer Julie C.
Published: August 2006

This primer briefly describes four emerging animal model systems that promise to provide insights into specific aspects of developmental biology. Highlighted here are two relatively well‐characterized model systems, Gasterosteus aculeatus (three‐spine stickleback fish) and Schmidtea mediterranea (planarian), as well as two organisms on which research is in its infancy, Carollia perspicillata (short‐tailed fruit bat), and the basal metazoan, Trichoplax adhaerens. Scientists who helped develop these species into model systems discuss why they chose to research these animals. Developmental Dynamics 235:2895–2899, 2006. © 2006 Wiley‐Liss, Inc.
Notch synergizes with axin to regulate the activity of armadillo in Drosophila
Authors: Hayward Penelope , Balayo Tina , Martinez Arias Alfonso
Published: August 2006

Cell fate decisions require the integration of various signalling inputs at the level of transcription and signal transduction. Wnt and Notch signalling are two important signalling systems that operate in concert in a variety of systems in vertebrates and invertebrates. There is evidence that the Notch receptor can modulate Wnt signalling and that its target is the activity and levels of Armadillo/β‐catenin. Here, we characterize this function of Notch in relation to Axin, a key element in the regulation of Wnt signalling that acts as a scaffold for the Shaggy/GSK3β‐dependent phosphorylation of Armadillo/β‐catenin. While Notch can regulate ectopic Wingless signalling caused by loss of function of Shaggy, it can only partially regulate the ectopic Wnt signalling induced by the loss of Axin function. The same interactions are observed in tissue culture cells where we observe a synergy in between Axin and Notch in the regulation of Armadillo/β‐catenin. Our results provide evidence for a function of Axin in the regulation of Armadillo that is different from its role as a scaffold for GSK3β.

Published: August 2006

Members of the Dact protein family initially were identified through binding to Dishevelled (Dvl), a cytoplasmic protein central to Wnt signaling. During mouse development, Dact1 is detected in the presomitic mesoderm and somites during segmentation, in the limb bud mesenchyme and other mesoderm‐derived tissues, and in the central nervous system (CNS). Dact2 expression is most prominent during organogenesis of the thymus, kidneys, and salivary glands, with much lower levels in the somites and in the developing CNS. Dact3, not previously described in any organism, is expressed in the ventral region of maturing somites, limb bud and branchial arch mesenchyme, and in the embryonic CNS; of the three paralogs, it is the most highly expressed in the adult cerebral cortex. These data are consistent with studies in other vertebrates showing that Dact paralogs have distinct signaling and developmental roles and suggest they may differentially contribute to postnatal brain physiology.

Modelling the Electron‐Transfer Complex Between Aldehyde Oxidoreductase and Flavodoxin
Authors: Krippahl Ludwig , Palma P. Nuno , Moura Isabel , Moura José J. G.
Published: August 2006

Three‐dimensional protein structures of the xanthine oxidase family show different solutions for the problem of transferring electrons between the flavin adenine dinucleotide (FAD) group and the molybdenum cofactor. In xanthine oxidase all the cofactors lie within domains of the same protein chain, whereas in CO dehydrogenase the Fe–S centres, FAD and Mo cofactors are enclosed in separate chains and the enzyme exists as a stable complex of all three. In aldehyde oxidoreductase, only Fe–S and Mo co‐factors are present in a single protein chain. Flavodoxin is docked to aldehyde oxidoreductase to mimic the flavin component on the intramolecular electron transfer chain of aanthine oxidase and CO dehydrogenase and, remarkably, the main features of the electron‐transfer pathway are observed.

Chiral Molecules Containing Metal–Metal Bonds
Authors: Cotton F. Albert , Murillo Carlos A.
Published: August 2006

Many chiral compounds having metal–metal bonds are now known in which the M–M unit is the chromophore. In this review they are classified as those where it is either (1) an inherently chiral chromophore owing to helical stacking of metal–ligand bonds, or (2) not inherently chiral but surrounded by a collection of ligands bearing chiral substituents. In only a few cases have the actual CD and/or ORD spectra been measured and analyzed. These include M2X4(PP)2 molecules (PP = a bridging diphosphane) and M2(O2CR)4 molcules where R is chiral. The more recently discovered helical extended metal atom chain (EMAC) molecules are also mentioned. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
Blue green algae in the biological soil crusts of different regions of India
Authors: Tirkey J. , Adhikary S. P.
Published: August 2006

Blue green algae (Cyanobacteria) occurring as biological soil crust intermingled with soil particles in the upper few millimeters of soil surfaces from different regions of India were studied. Sampling of crusts was done from four different soil types, i.e. laterite soils of the east coast, brown forest of soils of the east and central region, arid soils of the southern region and sandy soils of the west coast of India. One species each of the blue green algae Lyngbya arboricola, Scytonema ocellatum, Scytonema chiastum and Plectonema notatum as the dominant component in the four types of crust. Seve‐ ral other species of blue green algae belonging to genera Oscillatoria, Phormidium, Microcoleus, Nostoc, Aulosira, Calothrix, Hapalosiphon, Fischerella, Westiellopsis and Stigonema also appeared in the enrichment culture as minor components along with the dominant species. No other species of any other group of algae was a component of these crusts during the dry season. A total number of 48 species attributed to 15 different genera was encountered in different biological soil crusts of India. All these species are described with illustrations.

Contributions to the pollen morphology of the tribe Inuleae (subfamily Asteroideae‐Compositae) in the flora of Egypt
Authors: Osman A. K.
Published: August 2006

The pollen morphology of 18 species of tribe Inuleae belonging to 10 genera was examined by light and scanning microscopy. Pollen grains usually trizonocolpate to trizonocolporate rarely 4‐zonocolporate. Shape commonly oblate‐spheroidal to spheroidal, with some suboblate types. Tectum echinate to echinulate. Tectum in‐between the spines or spinules is sub‐psilate, perforate to scabrate or microreticulate. On the basis of the pollen class and the exine pattern, three distinct pollen types are recognized viz., Pollen type‐I: Anvillea garcinii, Pollen type‐II: Nauplius graveolens and Pollen type‐III: Pulicaria . Within the pollen types, pollen characters are significantly sufficient for characterization of the species. An interesting correlation observed is that the taxa having slightly thick exine (4–7 µm) with echinate or echinulate tectum. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Testa sculptures in Allium L. subg. Melanocrommyum (WEBB & BERTH.) Rouy (Alliaceae)
Authors: Fritsch R. M. , Kruse J. , Adler K. , Rutten T.
Published: August 2006

The sculptures and shape of the outer walls of seed epidermal cells were studied in a broad material from different sources. Convex periclinal walls with several to many large prominent sculptures (verrucae) occurred most often but generally the sculpturing was rather diverse. Most variable were the anticlinal walls. Mostly they were undulated with different amplitudes and wavelengths and belonged to three types (S‐like, U‐like, and Omega‐like undulation). Also transitions between these types occurred.
