Cost-Effective Marine Protection--A Pragmatic Approach.

ABSTRACT: This paper puts forward a framework for probabilistic and holistic cost-effectiveness analysis to provide support in selecting the least-cost set of measures to reach a multidimensional environmental objective. Following the principles of ecosystem-based management, the framework includes a flexible methodology for deriving and populating criteria for effectiveness and costs and analyzing complex ecological-economic trade-offs under uncertainty. The framework is applied in the development of the Finnish Programme of Measures (PoM) for reaching the targets of the EU Marine Strategy Framework Directive (MSFD). The numerical results demonstrate that substantial cost savings can be realized from careful consideration of the costs and multiple effects of management measures. If adopted, the proposed PoM would yield improvements in the state of the Baltic Sea, but the overall objective of the MSFD would not be reached by the target year of 2020; for various environmental and administrative reasons, it would take longer for most measures to take full effect.

Project description:Albeit much less abundant than Ser/Thr phosphorylation (pSer/pThr), Tyr phosphorylation (pTyr) is considered a hallmark in cellular signal transduction. However, its analysis remains a challenge. The conventional immunopurification (IP) approach using antibodies pan-specific to pTyr sites is known to have low sensitivity, poor reproducibility and high cost. SH2 domain-derived pTyr-superbinder is a good replacement of pTyr antibody for the specific enrichment of pTyr peptides for phosphoproteomics analysis. In this study, we aim to optimize the approach using SH2 superbinder for tyrosine phosphoproteome analysis. The present work covalently immobilized SH2 superbinders to agrose beads, designed and evaluated four different SH2 superbinder based experimental workflows for phosphotyrosine analysis. After made a head to head comparison of them, we observed that the combined strategy employing Ti4+-IMAC and covalently immobilized SH2 superbinder enrichment in sequence generated the largest pTyr peptide dataset (3519) with the best selectivity (90%). Next the optimal method was applied for pTyr profiling from normal mouse tissues, and resulted in the identification of 197 pTyr sites (of which 73 were novel) from 5 mg protein digests, which validated its high sensitivity. An comparison with antibody 4G10 by isolating pTyr peptides from 5 mg unstimulated Jurkat cell digests were made, our optimal strategy identified 343 while the antibody 4G10 based method identified 242 pTyr sites, respectively, further confirmed the robustness of the method. Finally, the optimal strategy was applied for quantitative pTyr phosphorylation analysis of EGF stimulated/unstimulated HeLa cells, 261 pTyr sites were successfully quantified from 5 mg stable-isotope dimethyl labling protein digests. In general, the combination of Ti4+-IMAC and SH2 superbinder enrichment in sequence generated a facial and robust strategy for qualitative and quantitative analysis of pTyr proteome.
