Europeans and Biotechnology in 2010. Winds of change?

George Gaskell and colleagues designed, analysed and interpreted the Eurobarometer 73.1 on the Life Sciences and Biotechnology as part of the research project Sensitive Technologies and European Public Ethics (STEPE), funded by the Science in Society Programme of the EC’s Seventh Framework Programme for Research and Technological Development (FP7).

Managing innovations in biotechnology

Estudi de la situació, estratègies i tendències de la gestió de les innovacions en biotecnologia. El projecte es desenvolupa amb participants de Polònia, França, Holanda i Espanya. Per tant, l'anàlisi té una perspectiva internacional, principalment centrada en els països esmentats. L'expliació teòrica contrasta amb un projecte de gestió real en una empresa de biotecnologia, amb les dades i la informació obtinguda en una visitat a una empresa de biotecnologia a Polònia

Caracterització estructural i funcional del gen de la miogenia en l’orada (Sparus aurata )

Report for the scientific sojourn at the University of Maryland Biotechnology Institute from February to August 2007. Myogenesis of skeletal muscles in vertebrates is controlled by extracellular signalling molecules together with intracellular transcription factors. Among the transcriptional factors, the members of the myogenic regulatory family play important roles regulating skeletal muscle development and growth. To characterize the gene structure and expression of fish myogenin, we have isolated the myogenin genomic gene and cDNA from gilthead seabream (Sparus aurata) and analyzed the genomic structure, pattern of expression and the regulation of musclespecific expression. Sequence analysis revealed that the seabream myogenin shares a similar gene structure with other fish myogenins, with three exons, two introns and the highly conserved bHLH domain. Expression studies demonstrated that myogenin is expressed in both slow and fast muscles as well as in muscle cells in primary culture. In situ hybridization showed that myogenin was specifically expressed in developing somites of seabream embryos. Promoter activity analysis demonstrated that the myogenin promoter could drive green fluorescence protein expression in muscle cells of zebrafish embryos, as well as in myofibers of adult zebrafish and juvenile seabream.

Analysing the innovation process in the EU Integrated Programme, ISAFRUIT

ISAFRUIT is an integrated European Union Project focussed on increasing fruit consumption as a means to improve human health, through evaluating the fruit chain and addressing bottlenecks therein.The innovations which are being developed throughout the ISAFRUIT Project have been analysed to determine both the success factors and the obstacles in reaching the commercialisation stage. Only 9.58% of the deliverables planned within the Project were focussed on developing technological innovations.There is evidence, however, of successes in the development of new innovations arising from the ISAFRUIT Project, with several other potential innovations in the pipeline. Of the technologies identified, 67% are still at the “invention stage”; that is, the stage prior to bridging the so-called “valley of death”, the stage between an invention and an innovation. Those which are considered to have moved over the “valley of death” either had industry partners included in the Project, or had consulted with industry to ensure that the technology was relevant, or met a recognised industry need. Many of the technologies which made less progress did not have the same interactions with industry. A number of other issues were identified which prevented further progress towards innovation. The need for scientists to publish scientific papers, both for their career pathways and to increase their chances of future funding, was identified as one issue, although the filing of patents is now becoming more accepted and recognised. The patenting system is considered complex by many scientists and is not well-understood. Finally, agreements between partners on the sharing of intellectual property rights can cause a delay in the innovation process.

Els cultius in vitro i el desenvolupament vegetal

Biotecnologia Vegetal de materials de treball que incorporin les TICs. El material elaborat ha estat un llibre electrònic utilitzable tant on-line (web) com off-line (CD). Els materials generats com a resultes d’aquest projecte han estat situats en un servidor de la UdL accessible des de l’exterior de la Universitat. Aquest llibre electrònic és d’accés obert i es pot consultar on-line a l’URL (http://sakai.udl.es/cursos/76304/indexC.htm). El llibre electrònic conté un total de 98 Mb d’informació hipermèdia i hipertexual distribuïda en més de 380 arxius dels quals 50 són pàgines html, 10 arxius doc, 10 arxius pdf, 258 imatges fixes i 8 arxius de vídeo en format flash (swf). L’accés al llibre electrònic es realitza a través d’una pantalla inicial que dóna pas a un menú que distribueix els materials en 7 apartats. Els textos estan acompanyats de gran quantitat d’imatges fotogràfiques, gràfics, esquemes, imatges infogràfiques i videoclips generats de novo per aquest projecte. En dissenyar la web s’han tingut en compte criteris de confiabilitat, accessibilitat i usabilitat. El primer disseny de la web ha estat validat per un panel d’usuaris i utilitzat posteriorment amb alumnes durant el curs 2007-2008. Les observacions i suggeriments fets per aquests ja han estat incorporats en aquest document final. Una primera enquesta de satisfacció realitzada amb aquest alumnat permet concloure, a títol provisional donat lo reduït de la població enquestada, que l’alumnat mostra un grau de coneixement de les eines TIC suficient i que consideren positiva la incorporació de materials multimèdia com a recurs educatiu. A més a més, la realització d’aquest projecte i la seva aplicació a l’aula ha estat presentada en dues ponències al “Congreso Internacional de Docencia y Innovación Universitaria”.

Conjugation of genetically-engineered protein phosphatases to magnetic particles for okadaic acid detection

This work presents the functional characterisation of a protein phosphatase 2A (PP2A) catalytic subunit obtained by genetic engineering and its conjugation to magnetic particles (MPs) via metal coordination chemistry for the subsequent development of assays for diarrheic lipophilic marine toxins. Colorimetric assays with free enzyme have allowed the determination of the best enzyme activity stabiliser, which is glycerol at 10%. They have also demonstrated that the recombinant enzyme can be as sensitive towards okadaic acid (OA) (LOD=2.3μg/L) and dinophysistoxin-1 (DTX-1) (LOD=15.2μg/L) as a commercial PP2A and, moreover, it has a higher operational stability, which makes possible to perform the protein phosphatase inhibition assay (PPIA) with a lower enzyme amount. Once conjugated to MPs, the PP2A catalytic subunit still retains its enzyme activity and it can also be inhibited by OA (LOD=30.1μg/L).

Identifying protein-coding genes in genomic sequences

The vast majority of the biology of a newly sequenced genome is inferred from the set of encoded proteins. Predicting this set is therefore invariably the first step after the completion of the genome DNA sequence. Here we review the main computational pipelines used to generate the human reference protein-coding gene sets.
