Mammalian cell cultures are the predominant system for the production of recombinant proteins requiring post-translational modifications. As protein yields are a function of growth performance (among others), and performance varies greatly between culture medium (e.g., different growth rates and peak cell densities), an understanding of the biological(More)
BACKGROUND Monoterpenes are a class of natural C10 compounds with a range of potential applications including use as fuel additives, fragrances, and chemical feedstocks. Biosynthesis of monoterpenes in heterologous systems is yet to reach commercially-viable levels, and therefore is the subject of strain engineering and fermentation optimization studies.(More)
Metabolomics being the most recently introduced "omic" analytical platform is currently at its development phase. For the metabolomics to be broadly deployed to biological and clinical research and practice, issues regarding data validation and reproducibility need to be resolved. Gas chromatography-mass spectrometry (GC-MS) will remain integral part of the(More)
Engineering the production of polyhydroxyalkanoates (PHAs) into high biomass bioenergy crops has the potential to provide a sustainable supply of bioplastics and energy from a single plant feedstock. One of the major challenges in engineering C4 plants for the production of poly[(R)-3-hydroxybutyrate] (PHB) is the significantly lower level of polymer(More)
Cell culture engineering has to-date used transcriptomic, proteomic, and metabolic flux analyses, attempting to resolve significant questions regarding cell culture performance. Despite the foreseen positive impact, the metabolomic analytical platform has not yet been vastly deployed. Presently, there is no published application of metabolomics to(More)
Although adult-onset hypothyroidism (AOH) has been connected to neural activity alterations, including movement, behavioral, and mental dysfunctions, the underlying changes in brain metabolic physiology have not been investigated in a systemic and systematic way. The current knowledge remains fragmented, referring to different experimental setups and(More)
Sesquiterpenes are C15 isoprenoids with utility as fragrances, flavours, pharmaceuticals, and potential biofuels. Microbial fermentation is being examined as a competitive approach for bulk production of these compounds. Competition for carbon allocation between synthesis of endogenous sterols and production of the introduced sesquiterpene limits yields.(More)
The urgent need for major gains in industrial crops productivity and in biofuel production from bioenergy grasses have reinforced attention on understanding C4 photosynthesis. Systems biology studies of C4 model plants may reveal important features of C4 metabolism. Here we chose foxtail millet (Setaria italica), as a C4 model plant and developed protocols(More)
BACKGROUND High-throughput screening methods assume that the output measured is representative of changes in metabolic flux toward the desired product and is not affected by secondary phenotypes. However, metabolic engineering can result in unintended phenotypes that may go unnoticed in initial screening. The red pigment lycopene, a carotenoid with(More)
1,5-Anhydroglucitol, an indicator of short term glycaemic control, is the most discriminatory metabolomic marker in adolescents with type 1 diabetes compared to control subjects Aim To compare the metabolomic profile of adolescents with T1D (≥5 years duration) to controls using gas chroma-tography–mass spectrometry (GC-MS). th per-centile.
