Abstract Porcine parvovirus (PPV) virus-like particles (VLPs) are a potential vaccine candidate for the prevention of parvovirus-induced reproductive failure in pregnant sows. Currently, the Escherichia coli (E. coli) expression system is the most cost-efficient to express recombinant proteins. To overcome the limitations of protein misfolding and to prepare soluble highly bioactive antigen and high yields of protein, we optimized the PPV-VP2 gene, subcloned it into pET24a, pET26b,...

Abstract Regulation of gene expression is fundamental for cellular function. Upon manipulation of the mechanism of gene expression in Escherichia coli, various bioproducts have been developed that are valuable industrially and medically in the last four decades. To efficiently produce bioproducts, numerous molecular tools are used for enhancing expression at the transcriptional and translational levels. Our recent discovery identified a new approach that enhances the gene expression...

Abstract Pyrodextrin (PD) is prepared from starch by heat treatment and is resistant to amylase. We hypothesized that PD might have prebiotic potential affecting the microbiota composition, because it contains a non-digestible portion that may behave as dietary fiber. This study investigated the effects of PD supplementation on growth performance, gut morphology, short-chain fatty acids (SCFAs), and the bacterial community in weaned piglets receiving dietary supplementation of...

Abstract Comparative analyses determined the relationship between the structure of bisphenol A (BPA) as well as of seven bisphenol analogues (bisphenol B (BPB), bisphenol C (BPC), bisphenol E (BPE), bisphenol F (BPF), bisphenol Z (BPZ), bisphenol AP (BPAP), bisphenol PH (BPPH)) and their biotransformability by the biphenyl-degrading bacterium Cupriavidus basilensis SBUG 290. All bisphenols were substrates for bacterial transformation with conversion rates ranging from 6 to 98%...

Abstract Prenyltransferase NovQ is a vital class involved in the biosynthesis of secondary metabolites such as clorobiocin and novobiocin. To investigate the relationship between structure and catalytic properties of NovQ, here, we have analyzed the substrate-binding site, namely PT barrel, and revealed that menadione hydroquinol formed intermolecular interactions with the residue Glu281 near the center of the active pocket. In this study, Glu281 was substituted with 9 diverse...

Abstract Panax ginseng is a traditional Chinese medicine with significant pharmaceutical effects and broad application. Rare ginsenosides with high antitumor activities can be generated via oriented modification of their glycosyl moiety. For this purpose, suitable microorganisms and their enzymatic systems can be used. In this review, we address several issues associated with these systems. Under aerobic conditions, fungus biotransformation provides an...

Abstract The prevalence of stomatitis, especially that caused by Candida albicans, has highlighted the need for new antifungal agents. We previously found that a type of quaternary ammonium salts, dimethylaminododecyl methacrylate (DMADDM), incorporated in dental materials inhibited the growth and hyphal development of C. albicans. However, how the quaternary ammonium salts inhibited the fungal pathogens and whether the oral condition, such as salivary pH variation under different...

Abstract Severe hyperbilirubinemia leads to bilirubin encephalopathy in neonates, causing irreversible neurological sequelae. We investigated the nature of neuronal selective vulnerability to unconjugated bilirubin (UCB) toxicity. The maintenance of intracellular calcium homeostasis is crucial for neuron survival. Calcium release from endoplasmic reticulum (ER) during ER-stress can lead to apoptosis trough the activation of Caspase-12. By live calcium imaging we monitored the generation...
