    Trends Biotechnol. (IF 14.343) Pub Date : 2020-07-09
    Sara Amorim; Celso A. Reis; Rui L. Reis; Ricardo A. Pires

    Hyaluronan (HA) is a critical element of the extracellular matrix (ECM). The regulated synthesis and degradation of HA modulates the ECM chemical and physical properties that, in turn, influence cellular behavior. HA triggers signaling pathways associated with the adhesion, proliferation, migration, and differentiation of cells, mediated by its interaction with specific cellular receptors or by tuning

    In plants, prenylation of aromatic compounds, such as (iso)flavonoids and stilbenoids, by membrane-bound prenyltransferases (PTs), is an essential step in the biosynthesis of many bioactive compounds. Prenylated aromatic compounds have various health-beneficial properties that are interesting for industrial applications, but their exploitation is limited due to their low abundance in nature. Harnessing

    Most of the studies employing neuroimaging have focused on cortical and subcortical signals individually to obtain neurophysiological signatures of cognitive functions. However, understanding the dynamic communication between the cortex and subcortical structures is essential for unraveling the neural correlates of cognition. In this quest, magnetoencephalography (MEG) and electroencephalography (EEG)

    Large-scale production of induced pluripotent stem cells (iPSCs) is essential for the treatment of a variety of clinical indications. However, culturing enough iPSCs for clinical applications is problematic due to their sensitive pluripotent state and dependence on a supporting matrix. Developing stem cell bioprocessing strategies that are scalable and meet clinical needs requires incorporating methods

    Mammalian cells are the main tool for the production of therapeutic proteins, viruses for gene therapy, and cells for cell therapy. In production processes cell metabolism is the main driver that causes changes in the growth environment and affects productivity and product quality. Of all nutrients, glucose has the most prominent impact on bioprocesses. We summarize recent findings on the regulation

  • On-Site Therapeutic Drug Monitoring
    Trends Biotechnol. (IF 14.343) Pub Date : 2020-04-02
    H. Ceren Ates; Jason A. Roberts; Jeffrey Lipman; Anthony E.G. Cass; Gerald A. Urban; Can Dincer

    Recent technological advances have stimulated efforts to bring personalized medicine into practice. Yet, traditional application fields like therapeutic drug monitoring (TDM) have remained rather under-appreciated. Owing to clear dose-response relationships, TDM could improve patient outcomes and reduce healthcare costs. While chromatography-based routine practices are restricted due to high costs

    Production of biologics in plants, or plant molecular pharming, is a promising protein expression technology that is receiving increasing attention from the pharmaceutical industry. Previously, low expression yields of recombinant proteins and the realization that certain post-translational modifications (PTMs) may not occur optimally limited the widespread acceptance of the technology. However, molecular

  • Microalgal Torrefaction for Solid Biofuel Production
    Trends Biotechnol. (IF 14.343) Pub Date : 2020-03-23
    Shih-Hsin Ho; Congyu Zhang; Fei Tao; Chaofan Zhang; Wei-Hsin Chen

    Microalgae are recognized as promising feedstocks for biofuel production and have been intensively studied. However, a systematic investigation of the relationship between cellular components and fuel properties in microalgae is currently absent. This review introduces recent advances in microalgal torrefaction and critically evaluates the properties of torrefied products from the viewpoint of molecular

    Combining the diverse chemical functionality of proteins with the predictable structural assembly of nucleic acids has enabled the creation of hybrid nanostructures for a range of biotechnology applications. Through the attachment of proteins onto or within nucleic acid nanostructures, materials with dynamic capabilities can be created that include switchable enzyme activity, targeted drug delivery

    Microbial production of medium-chain fatty acids (MCFAs) is challenging, as they are rare metabolites and toxic to cells. Recently, Zhu et al. performed multidimensional engineering in Saccharomyces cerevisiae, including engineering fatty acid synthases and improving cellular tolerance to MCFAs, to build an efficient MCFA cell factory.

  • Burkholderia: An Untapped but Promising Bacterial Genus for the Conversion of Aromatic Compounds
    Trends Biotechnol. (IF 14.343) Pub Date : 2020-03-18
    Raj Morya; Davinia Salvachúa; Indu Shekhar Thakur

    Burkholderia, a bacterial genus comprising more than 120 species, is typically reported to inhabit soil and water environments. These Gram-negative bacteria harbor a variety of aromatic catabolic pathways and are thus potential organisms for bioremediation of sites contaminated with aromatic pollutants. However, there are still substantial gaps in our knowledge of these catabolic processes that must
