Transcriptome analysis of the murine forelimb and hindlimb autopod
Authors: Shou Siming , Scott Virginia , Reed Cheryl , Hitzemann Robert , Stadler H. Scott 
Published: July 2005

AbstractTo gain insight into the coordination of gene expression profiles during forelimb and hindlimb differentiation, a transcriptome analysis of mouse embryonic autopod tissues was performed using Affymetrix Murine Gene Chips (MOE‐430). Forty‐four transcripts with expression differences higher than 2‐fold (T test, P ≤0.05) were detected between forelimb and hindlimb tissues including 38 new transcripts such as Rdh10, Frzb, Tbx18, and Hip that exhibit differential limb expression. A comparison of gene expression profiles in the forelimb, hindlimb, and brain revealed 24 limb‐signature genes whose expression was significantly enriched in limb autopod versus brain tissue (fold change >2, P ≤ 0.05). Interestingly, the genes exhibiting enrichment in the developing autopod also segregated into significant fore‐ and hindlimb‐specific clusters (P ≤ 0.05) suggesting that by E 12.5, unique gene combinations are being used during the differentiation of each autopod type.

Expression of mouse dchs1, fjx1, and fat‐j suggests conservation of the planar cell polarity pathway identified in drosophila
Authors: Rock Rebecca , Schrauth Sabrina , Gessler Manfred 
Published: July 2005

AbstractThe dachsous (ds), fat (ft), and four‐jointed (fj) genes have been identified in Drosophila as part of a signaling pathway that regulates planar cell polarity (PCP). A homologous PCP signaling pathway has also been identified in vertebrates, but nothing is known thus far about the conservation of Ds/Ft/Fj signaling. Here we analyzed and compared for the first time the expression patterns of all ds, ft and fj homologs in the mouse. During embryogenesis, expression analysis was performed by RNA in situ hybridization and in adult organs by real time PCR. As in Drosophila, we detected a complementary expression of fjx1 and dchs1 in organs like kidney, lung, and intestine. The ubiquitous expression of ft in several tissues in Drosophila appears to be split into an epithelial expression of fat1/fat3 and a mesenchymal expression of fat‐j. These data are compatible with a conservation and subfunctionalization of the Drosophila Ds, Fj, and Fat signaling in higher vertebrates.

Proneural factors and neurogenesis
Authors: Kiefer Julie C. 
Published: July 2005

AbstractThe role of proneural factors in specifying neuronal progenitors and in promoting neuronal differentiation is conserved from Drosophila to vertebrates. This primer discusses the basic functions of proneural factors in neurogenesis, mechanisms of proneural factor function, and models for how proneural factors generate neuronal subtypes. The primer also features a dialog about current topics and future directions in the field between two experts in neurogenesis: Andrew Jarman, Ph.D., and Jane Johnson, Ph.D. Developmental Dynamics 234:808–813, 2005. © 2005 Wiley‐Liss, Inc.
Abundance, Population Structure and Production of Scrobicularia plana and Abra tenuis (Bivalvia: Scrobicularidae) in a Mediterranean Brackish Lagoon, Lake Ichkeul, Tunisia
Authors: Casagranda Caterina , Boudouresque Charles François 
Published: July 2005

AbstractAbundance, growth and production of the deposit‐feeding bivalves were studied in the Ichkeul wetland, northern Tunisia, from July 1993 – April 1994. Scrobicularia plana (Da Costa, 1778) occurred at annual mean densities (biomasses) of 299 ± 65 to 400 ± 100 individuals/m2 (22.54 ± 3.00 to 34.27 ± 3.96 g ash‐free dry mass (AFDM)/m2) depending on the study area. The annual mean density of Abra tenuis (Montagu, 1803) amounted to 640 ± 74 individuals/m2 during the whole study period, in contrast the biomass rose from 2.87 g AFDM/m2 in July to 10.29 g AFDM/m2 in April. Both species were largely dominated by age class I. Although not very successful, recruitment presented a two‐period pattern: the main period at the beginning of spring, and a secondary one in late summer/autumn. S. plana rarely exceeded 40 mm and lived for only 2 years, while most individuals of A. tenuis lived for only 15–18 months growing to a length of 12 mm. The annual bivalve deposit‐feeder production for the whole lagoon system (90 km2) was 8.24 g AFDM/m2 (5.26 g C/m2, 0.65 g N/m2). The annual P/$ \bar B $ ratio was about 0.4 and therefore in the same order of magnitude as estimates from other brackish coastal waters. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Factors Influencing the Seasonal Phenology and Composition of Zooplankton Communities in Mountain Temporary Pools
Authors: Tavernini Silvia , Mura Graziella , Rossetti Giampaolo 
Published: July 2005

AbstractIn 2001 nine temporary pools of the northern Apennines (Italy) were visited on 13 occasions during the ice‐free season (May to October). The aims of this research were to define the relationships between hydroperiod and other environmental variables and the zooplankton. In total, 49 zooplankton taxa were identified: 36 rotifers, 5 cladocerans, 6 copepods and 2 anostracans. Our results indicate that hydroperiod is a major determinant affecting zooplankton species richness. The highest number of taxa was found in the pond having the longest duration. Distinctive species assemblages were observed in different habitat types: pools with the shortest hydroperiod were characterised by organisms with brief life cycles (e.g. rotifers) and/or typical of temporary habitat (e.g. anostracans). Of the physical and chemical characteristics, pH and chlorophyll‐a appeared to have the largest influence on zooplankton distribution in the studied pools. (© 2005 WILEY‐VCH Verlag GmbH & Co.

Effects of controlled fibronectin surface orientation on subsequent Staphylococcus epidermidis adhesion
Authors: Jarvis R. A. , Bryers J. D. 
Published: July 2005

AbstractSeveral bacterial species, including Staphylococcus aureus and Staphylococcus epidermidis (SE) are known to express cell receptors that bind specifically to surface immobilized or extracellular matrix ligands, such as the protein fibronectin (FN). Yet, few existing studies have examined the effect of protein surface orientation on bacterial adhesion. We report here a substratum modification protocol that allows for the specific orientation of FN molecules on a surface at known levels of surface coverage. Monoclonal antibodies (Mabs), specific to either the COOH‐terminus or NH3‐terminus of FN, are conjugated to biotin, then immobilized to streptavidin‐coated glass substrata. Specific orientation of the bound FN molecules is verified using the same Mabs in an ELISA. Bacterial adhesion of Staphylococcus epidermidis (SE) to FN bound by either its C‐terminus or its NH3‐terminus was quantified in batch static adhesion assays. Results indicate an increase in SE adhesion to FN‐coated surfaces when the FN is bound by its C‐terminus (NH3‐terminus free), indicating SE receptor‐specific adhesion to the FN NH3‐terminus. These studies demonstrate that antifibronectin monoclonal antibodies can be used to specifically bind and orient fibronectin on a surface. In addition, adhesion of SE to these model substrata can be controlled by the orientation of the protein. © 2005 Wiley Periodicals, Inc. J Biomed Mater Res, 2005
