Enzyme screening with synthetic multifunctional pores: focus on biopolymers.

ABSTRACT: This report demonstrates that a single set of identical synthetic multifunctional pores can detect the activity of many different enzymes. Enzymes catalyzing either synthesis or degradation of DNA (exonuclease III or polymerase I), RNA (RNase A), polysaccharides (heparinase I, hyaluronidase, and galactosyltransferase), and proteins (papain, ficin, elastase, subtilisin, and pronase) are selected to exemplify this key characteristic of synthetic multifunctional pore sensors. Because anionic, cationic, and neutral substrates can gain access to the interior of complementarily functionalized pores, such pores can be the basis for very user-friendly screening of a broad range of enzymes.

Multifunctional Enzyme Nanocapsules Boost T Cell Immunity and Multifunctional Enzyme Nanocapsules Boost T Cell Immunity and Efficacy of Cancer Immunotherapy

Project description:Cancer immunotherapy has reshaped the landscape of cancer treatment, but its effectiveness is limited by tumor immunosuppression caused by excessive lactate production by cancer cells. While efforts to reduce lactate levels through lactate dehydrogenase inhibition have been made, such inhibitors can disrupt the metabolism of healthy cells and cause severe non-specific toxicity. Based on lactate oxidase, we report herein an enzyme therapeutic, which reduces lactate levels, releases an immunostimulatory molecule-hydrogen peroxide, averts tumor immunosuppression, and synergistically improves the efficacy of immune checkpoint blockades, as demonstrated in a murine melanoma model and a humanized mouse model of triple-negative breast cancer.

Open-closed switching of synthetic tubular pores.

Project description:While encouraging progress has been made on switchable nanopores to mimic biological channels and pores, it remains a great challenge to realize long tubular pores with a dynamic open-closed motion. Here we report μm-long, dynamic tubular pores that undergo rapid switching between open and closed states in response to a thermal signal in water. The tubular walls consist of laterally associated primary fibrils stacked from disc-shaped molecules in which the discs readily tilt by means of thermally regulated dehydration of the oligoether chains placed on the wall surfaces. Notably, this pore switching mediates a controlled water-pumping catalytic action for the dehydrative cyclization of adenosine monophosphate to produce metabolically active cyclic adenosine monophosphate. We believe that our work may allow the creation of a variety of dynamic pore structures with complex functions arising from open-closed motion.

Development of multifunctional synthetic nucleosomes

Project description:Various proteins bind to chromatin to regulate DNA and its associated processes such as replication, transcription, and damage repair. The identification and characterization of these chromatin-associating proteins remain a challenge, as their interactions with chromatin often occur within the context of the local nucleosome or chromatin structure, which makes conventional peptide-based strategies unsuitable.

Synthetic approaches to multifunctional indenes.

Project description:The synthesis of multifunctional indenes with at least two different functional groups has not yet been extensively explored. Among the plausible synthetic routes to 3,5-disubstituted indenes bearing two different functional groups, such as the [3-(aminoethyl)inden-5-yl)]amines, a reasonable pathway involves the (5-nitro-3-indenyl)acetamides as key intermediates. Although several multistep synthetic approaches can be applied to obtain these advanced intermediates, we describe herein their preparation by an aldol-type reaction between 5-nitroindan-1-ones and the lithium salt of N,N-disubstituted acetamides, followed immediately by dehydration with acid. This classical condensation process, which is neither simple nor trivial despite its apparent directness, permits an efficient entry to a variety of indene-based molecular modules, which could be adapted to a range of functionalized indanones.

Fabrication of Porous Materials from Natural/Synthetic Biopolymers and Their Composites.

Project description:Biopolymers and their applications have been widely studied in recent years. Replacing the oil based polymer materials with biopolymers in a sustainable manner might give not only a competitive advantage but, in addition, they possess unique properties which cannot be emulated by conventional polymers. This review covers the fabrication of porous materials from natural biopolymers (cellulose, chitosan, collagen), synthetic biopolymers (poly(lactic acid), poly(lactic-co-glycolic acid)) and their composite materials. Properties of biopolymers strongly depend on the polymer structure and are of great importance when fabricating the polymer into intended applications. Biopolymers find a large spectrum of application in the medical field. Other fields such as packaging, technical, environmental, agricultural and food are also gaining importance. The introduction of porosity into a biomaterial broadens the scope of applications. There are many techniques used to fabricate porous polymers. Fabrication methods, including the basic and conventional techniques to the more recent ones, are reviewed. Advantages and limitations of each method are discussed in detail. Special emphasis is placed on the pore characteristics of biomaterials used for various applications. This review can aid in furthering our understanding of the fabrication methods and about controlling the porosity and microarchitecture of porous biopolymer materials.

Electromechanical unzipping of individual DNA molecules using synthetic sub-2 nm pores.

Project description:Nanopores have recently emerged as high-throughput tools for probing and manipulating nucleic acid secondary structure at the single-molecule level. While most studies to date have utilized protein pores embedded in lipid bilayers, solid-state nanopores offer many practical advantages which greatly expand the range of applications in life sciences and biotechnology. Using sub-2 nm solid-state nanopores, we show for the first time that the unzipping kinetics of individual DNA duplexes can be probed by analyzing the dwell-time distributions. We performed high-bandwidth electrical measurements of DNA duplex unzipping as a function of their length, sequence, and temperature. We find that our longer duplexes (>10 bp) follow Arrhenius dependence on temperature, suggesting that unzipping can be approximated as a single-barrier crossing, but the unzipping kinetics of shorter duplexes do not involve a barrier, due to the strong biasing electrical force. Finally, we show that mismatches in the duplex affect unzipping times in a position-sensitive manner. Our results are a crucial step toward sequence variability detection and our single-molecule nanopore sequencing technology, which rely on parallel detection from nanopore arrays.

Enzyme engineering: A synthetic biology approach for more effective library generation and automated high-throughput screening.

Project description:The Golden Gate strategy entails the use of type IIS restriction enzymes, which cut outside of their recognition sequence. It enables unrestricted design of unique DNA fragments that can be readily and seamlessly recombined. Successfully employed in other synthetic biology applications, we demonstrate its advantageous use to engineer a biocatalyst. Hot-spots for mutations were individuated in three distinct regions of Candida antarctica lipase A (Cal-A), the biocatalyst chosen as a target to demonstrate the versatility of this recombination method. The three corresponding gene segments were subjected to the most appropriate method of mutagenesis (targeted or random). Their straightforward reassembly allowed combining products of different mutagenesis methods in a single round for rapid production of a series of diverse libraries, thus facilitating directed evolution. Screening to improve discrimination of short-chain versus long-chain fatty acid substrates was aided by development of a general, automated method for visual discrimination of the hydrolysis of varied substrates by whole cells.

Multifunctional synthetic Bowman's membrane-stromal biomimetic for corneal reconstruction.

Project description:As the outermost layer of the eye, the cornea is vulnerable to physical and chemical trauma, which can result in loss of transparency and lead to corneal blindness. Given the global corneal donor shortage, there is an unmet need for biocompatible corneal substitutes that have high transparency, mechanical integrity and regenerative potentials. Herein we engineered a dual-layered collagen vitrigel containing biomimetic synthetic Bowman's membrane (sBM) and stromal layer (sSL). The sBM supported rapid epithelial cell migration, maturation and multilayer formation, and the sSL containing tissue-derived extracellular matrix (ECM) microparticles presented a biomimetic lamellar ultrastructure mimicking the native corneal stroma. The incorporation of tissue-derived microparticles in sSL layer significantly enhanced the mechanical properties and suturability of the implant without compromising the transparency after vitrification. In vivo performance of the vitrigel in a rabbit anterior lamellar keratoplasty model showed full re-epithelialization within 14 days and integration of the vitrigel with the host tissue stroma by day 30. The migrated epithelial cells formed functional multilayer with limbal stem cell marker p63 K14 expressed in the lower layer, epithelial marker K3 and K12 expressed through the layers and tight junction protein ZO-1 expressed by the multilayers. Corneal fibroblasts migrated into the implants to facilitate host/implant integration and corneal stromal regeneration. In summary, these results suggest that the multi-functional layers of this novel collagen vitrigel exhibited significantly improved biological performance as corneal substitute by harnessing a fast re-epithelialization and stromal regeneration potential.

Focus on lung cancer screening.

Project description:Poor survival of lung cancer (LC) patients depends on several factors first of all the delay in the diagnosis, considering that the majority of patients have an advanced-stage disease at the time of diagnosis. In this context, use of screening to increase the percentage of early LC detection can play a crucial role. After the preliminary unsatisfactory experiences with chest X-rays and sputum cytology, low dose computed tomography (LDCT) has become the best method for LC screening. In particular, several randomized LDCT screening trials conducted in the last year showed significant reductions in LC mortality in high-risk subjects. This review focuses on both recent advances in LC screening and some open questions.

Novel multifunctional RKKY coupling layer for ultrathin perpendicular synthetic antiferromagnet.

Project description:A novel multi-functional antiferromagnetic coupling layer (MF-AFC) combining Ru and W is revealed to realize an extremely thin (3.8 nm), back-end-of-line compatible as well as magnetically and electrically stable perpendicular synthetic antiferromagnetic layer (pSAF), essential for spintronic memory and logic device applications. In addition to achieving antiferromagnetic RKKY coupling, this MF-AFC also acts as a Boron sink and texture-breaking layer. A detailed optimization of the thickness of the various involved layers has been carried out to obtain extremely thin-pSAF reference layer with stable magnetic properties, which enables the realization of sub-20 nm STT-MRAM cells. Two important advantages are provided by this ultrathin reference layer: the easing of the reference layer etching and the minimization of the dipolar field acting on the storage layer magnetization.
