TL;DR: In this paper, a review of the corporate social reporting literature, its major theoretical preoccupations and empirical conclusions, attempts to re-examine the theoretical tensions that exist between “classical” political economy interpretations of social disclosure and those from more “bourgeois” perspectives.
Abstract: Takes as its departure point the criticism of Guthrie and Parker by Arnold and the Tinker et al. critique of Gray et al. Following an extensive review of the corporate social reporting literature, its major theoretical preoccupations and empirical conclusions, attempts to re‐examine the theoretical tensions that exist between “classical” political economy interpretations of social disclosure and those from more “bourgeois” perspectives. Argues that political economy, legitimacy theory and stakeholder theory need not be competitor theories but may, if analysed appropriately, be seen as alternative and mutually enriching theories from alternative levels of resolution. Offers evidence from 13 years of social disclosure by UK companies and attempts to interpret this from different levels of resolution. There is little doubt that social disclosure practice has changed dramatically in the period. The theoretical perspectives prove to offer different, but mutually enhancing, interpretations of these phenomena.

TL;DR: A new appreciation of the role of polypharmacology has significant implications for tackling the two major sources of attrition in drug development--efficacy and toxicity.
Abstract: The dominant paradigm in drug discovery is the concept of designing maximally selective ligands to act on individual drug targets. However, many effective drugs act via modulation of multiple proteins rather than single targets. Advances in systems biology are revealing a phenotypic robustness and a network structure that strongly suggests that exquisitely selective compounds, compared with multitarget drugs, may exhibit lower than desired clinical efficacy. This new appreciation of the role of polypharmacology has significant implications for tackling the two major sources of attrition in drug development--efficacy and toxicity. Integrating network biology and polypharmacology holds the promise of expanding the current opportunity space for druggable targets. However, the rational design of polypharmacology faces considerable challenges in the need for new methods to validate target combinations and optimize multiple structure-activity relationships while maintaining drug-like properties. Advances in these areas are creating the foundation of the next paradigm in drug discovery: network pharmacology.

TL;DR: In this paper, a protein kinase that phosphorylates PKB α at Thr308 and increases its activity over 30-fold was found to play a key role in mediating the activation of PKB by insulin and growth factors.

TL;DR: In this paper, the activation of PKBalpha was accompanied by its phosphorylation at Thr308 and Ser473 and, like activation, likeactivation was prevented by the phosphatidylinositol 3-kinase inhibitor wortmannin.
Abstract: Insulin activated endogenous protein kinase B alpha (also known as RAC/Akt kinase) activity 12-fold in L6 myotubes, while after transfection into 293 cells PKBalpha was activated 20- and 50-fold in response to insulin and IGF-1 respectively. In both cells, the activation of PKBalpha was accompanied by its phosphorylation at Thr308 and Ser473 and, like activation, phosphorylation of both of these residues was prevented by the phosphatidylinositol 3-kinase inhibitor wortmannin. Thr308 and/or Ser473 were mutated to Ala or Asp and activities of mutant PKBalpha molecules were analysed after transfection into 293 cells. The activity of wild-type and mutant PKBalpha was also measured in vitro after stoichiometric phosphorylation of Ser473 by MAPKAP kinase-2. These experiments demonstrated that activation of PKBalpha by insulin or insulin-like growth factor-1 (IGF-1) results from phosphorylation of both Thr308 and Ser473, that phosphorylation of both residues is critical to generate a high level of PKBalpha activity and that the phosphorylation of Thr308 in vivo is not dependent on phosphorylation of Ser473 or vice versa. We propose a model whereby PKBalpha becomes phosphorylated and activated in insulin/IGF-1-stimulated cells by an upstream kinase(s).
