In a 2-L fed-batch fermenter, viable cell number of the triple deletion mutant BA ΔSDE increased by 2.79 Log/cfu/mL, and the activity of acid-stable alpha-amylase increased by 48.4%, compared to BA Δupp. Systematic multiple peptidoglycan hydrolases deletion relieved the autolysis and increased the production of industrial enzymes, and provided a useful strategy for guiding efforts to manipulate the genomes of other B. amyloliquefaciens used for chassis host.Toll-like receptors play significant roles in defensing against pathogen invasion. In this study, TLR4 and TRIL from Yellow catfish Tachysurus fulvidraco (Tf), were identified and characterized. The open reading frames of the Tf_TLR4 and Tf_TRIL genes were 2466 bp and 1827 bp in length, encoding 821 and 608 amino acids, respectively. The Tf_TLR4 consists of LRRs, a transmembrane domain and a TIR domain, and Tf_TRIL only contains LRRs and TIR domain. Homologous identity revealed that both Tf_TLR4 and Tf_TRIL have high protein sequence similarity with that of channel catfish Ictalurus punctatus. Both the Tf_TLR4 and Tf_TRIL genes were highly expressed in head kidney and brain, respectively. selleck chemicals llc The mRNA expression levels of Tf_TLR4 and Tf_TRIL genes were up-regulated in intestine and immune-related tissues after challenge of Edwardsiella ictaluri. The microscopic observation of the gut showed that the pathological changes in midgut and hindgut are more obvious than that in foregut after challenged with E. ictaluri. These results indicate that these two genes play potential roles in the host defense against E. ictaluri invasion. This study will provide valuable information to better understand the synergistic roles of TLR4 and TRIL in the innate immune system of yellow catfish and other fish.Micro/nanomotors (MNMs), both self-propelled actuators and external fields-promoted machines, have joined forces in the past decade to accomplish versatile tasks such as precise detection and targeted cargo delivery with adequate propulsion and desirable locomotion. Amongst, enzyme-driven MNMs have been able to differentiate themselves from others owing to their distinct characteristics, such as absence of chemical fuel, enhanced cellular uptake and the possibility to be easily conjugated with many therapeutics, including both small molecules and biologics, displaying superior efficacy, enhanced specificity and diminished side effects. In the present review, we aim to highlight and summarize recent advances in enzyme-driven MNMs, particularly to provide an in-depth discussion focusing on the enzyme linking approaches onto those MNMs and motion control strategies of such MNMs with advantages and limitations thereof. Conclusions and future perspectives are also provided in brief.Acute liver failure is an uncommon and dramatic clinical syndrome with a high risk of mortality. Previous treatments existed some limitations of poor bioavailability and targeting the efficiency of drugs. In this study, a novel glycyrrhizin mediated liver-targeted alginate nanogels, which can deliver the antioxidant quercetin to the liver for the treatment of acute liver injury. In vitro radical scavenging results showed that the antioxidant activity of quercetin was increased 81-fold. The tissue distribution results indicated that glycyrrhizin-mediated nanogels showed stronger fluorescence intensity in the liver, which improved liver targeting and therapeutic efficacy. Quercetin-glycyrrhizin nanogels were more effective at restoring liver injury as indicated on serum markers, including alanine transaminase, aspartate aminotransferase, and total bilirubin. The histopathology result showed that quercetin-glycyrrhizin nanogels reversed liver damage. Oxidative parameters of malondialdehyde and glutathione s-transferase were decreased, which provided supporting evidence of antioxidation. Moreover, quercetin-glycyrrhizin nanogels were more effective in down-regulating the inflammation-related gene expression of tumor necrosis factor-α, interleukin-6, inducible nitric oxide synthase and monocyte chemotactic protein-1. In conclusion, the novel glycyrrhizin mediated liver-targeted alginate nanogels might be a promising treatment for acute liver failure.Transforming growth factor beta 3 (TGFβ3) exhibits a complex native structure featuring the presence of multiple disulfide bonds forming the active dimer. Consequently, its heterologous expression in microbial system invariably leads to inclusion body (IB) formation. In this study, we observed an interesting phenomenon of switching a significant fraction of misfolded TGFβ3 to folded form by modulating the cellular protein folding machinery. We carried out co-expression experiments with chaperones and demonstrated the requirement of a coordinated action of DnaK-DnaJ-GrpE and GroESL, to achieve the native soluble conformation of TGFβ3, during over-expression in E. coli. The novelty of this study lies in the fact that orchestration of a group of chaperones to work in concert for efficient folding and assembly of TGFβ3-like cytokines has not been widely explored. Additionally, we have also demonstrated that presence of osmolytes (sorbitol or trehalose) in the growth media have an appreciable impact on the solubility of TGFβ3. We have further shown a synergism between the effects of molecular chaperone and osmolytes on the solubility of TGFβ3. We have confirmed the functionality of soluble TGFβ3 by performing binding interactions with its cognate receptor TβRII. Our study delineates the fact that an effective combination of chaperones or optimum concentration of compatible osmolyte, can efficiently abrogate competing aggregation pathways and help attain the native conformation of a cysteine rich cytokine in a facile manner.With the further research in recent years, Flammulina velutipes (F. velutipes), an edible mushroom, has great application value in many fields. As one of the main bioactive components in F. velutipes, polysaccharide has a series of functions such as anti-oxidation, immune regulation, anti-inflammation, liver protection, anti-tumor, anti-hyperlipidemia and so on. In this paper, the current progress in the extraction, purification, structural characteristics and bioactivities of F. velutipes polysaccharides (FVPs) were reviewed. Meanwhile, the structural-property relationships of FVPs were further discussed. In addition, based on in vitro and in vivo experiments, the possible mechanisms of bioactivities of FVPs were summarized. In order to understand FVPs more comprehensively, the application status and the future research work of FVPs were also introduced. Finally, we hope that our research can provide a reference for further research and development of FVPs.
