G protein-coupled receptors (GPCRs) mediate multiple key biological processes in the body. The orphan receptor GPR39 has been reported to be involved in various pathophysiological events. However, the function of GPR39 in skin biology remains unknown. Using a genetically engineered mouse strain in which lacZ expression faithfully replaced endogenous Gpr39 expression, we discovered a unique expr...

The history of mouse genetics, which involves the study of strain-dependent phenotype variability, makes it clear that the genetic background onto which a gene-targeted allele is placed can cause considerable variation in genetically engineered mouse (GEM) phenotype. This variation can present itself as completely different phenotypes, as variations in penetrance of phenotype, or as variable ex...

Hand ISSN The point of departure for the study of the impact of energy and environmental policies is the neoclassical theory of economic growth formulated by Cass (1965) and Koopmans (1967). The longrun properties of economic growth models are independent of energy and environmental policies. However, these policies affect capital accumulation and rates of productivity growth that determine the...

the potential and performance of various gram-negative, gram-positive and archaeal wild type microorganisms, and bacterial mixed cultures, as well as the application of genetically engineered strains as whole-cell biocatalysts for glycerol-based polyhydroxyalkanoate production are analyzed and assessed. this encompasses the comparison of growth and polyhydroxyalkanoate accumulation kinetics, th...

Immunotherapy with genetically engineered T-cells that express the chimeric antigen receptor (CAR) has raised hopes for the treatment of pediatric malignancies. Although CAR T-cell development is on a fast-moving pace and evolution, the context of exploring novel targetable antigens has been neglected. In this review study, we analyze the prominent hematologic antigens targeted by engineered T-...

Laboratory-contained microcosms are important for studying the fate and survival of genetically engineered microorganisms. In this study, we describe a simple aquatic microcosm that utilizes survival chambers in a flowthrough or static renewal system. The model was used to study the survival of genetically engineered and wild-type strains of Escherichia coli and Pseudomonas putida in the lake w...

The use of intravascular stents may be limited by both local thrombosis and restenosis due to intimal proliferation. In an effort to provide solutions to these problems, we seeded stents with genetically engineered endothelial cells in vitro. Using retroviral-mediated gene transfer, we inserted the gene for either bacterial beta-galactosidase or human tissue-type plasminogen activator (t-PA) in...

Modularity the notion that individual components can be described as self-contained units and composed in different combinations is a concept integral to synthetic biology. In vitro, it is embodied by the notion of BioBrickparts: standardised DNA sequences of defined structure, function, and common interfaces that can be composed and integrated into living cells. A similar modularity in the mod...
