Plasmids are used extensively in basic and applied biology. However, design and construction of plasmids, specifically the ones carrying complex genetic information, remains one of the most time-consuming, labor-intensive, and rate-limiting steps in performing sophisticated biological experiments. Here, we report the development of a versatile, robust, automated end-to-end platform named PlasmidMaker that allows error-free construction of plasmids with virtually any sequences in a high throughput manner. This platform consists of a most versatile DNA assembly method using Pyrococcus furiosus Argonaute (PfAgo)-based artificial restriction enzymes, a user-friendly frontend for plasmid design, and a backend that streamlines the workflow and integration with a robotic system. As a proof of concept, we used this platform to generate 101 plasmids from six different species ranging from 5 to 18 kb in size from up to 11 DNA fragments. PlasmidMaker should greatly expand the potential of synthetic biology.

Skin aging is one of the degenerative processes influenced by tyrosinase, elastase, collagenase, hyaluronidase, and matrix metalloproteinase-9 (MMP9) activity. One promising avenue for discovering antiaging therapeutics is the peptides from the spine. The aim of this study was to explore the potential of peptides from spine as a multitarget inhibitor for recombinant antiaging therapies through in silico approaches.

Construction of antibiotic-free riboflavin producer in by metabolic engineering strategies with a plasmid stabilization system.

Synth Syst Biotechnol

June 2025

Key Laboratory of Industrial Biotechnology, Ministry of Education, School of Biotechnology, Jiangnan University, Wuxi, Jiangsu 214122, China.

Riboflavin, an important vitamin utilized in pharmaceutical products and as a feed additive, is mainly produced by metabolically engineered bacterial fermentation. However, the reliance on antibiotics in the production process leads to increased costs and safety risks. To address these challenges, an antibiotic-free riboflavin producer was constructed using metabolic engineering approaches coupled with a novel plasmid stabilization system.

Background: Non-small cell lung cancer (NSCLC) is a disease related to inflammation. Proinflammatory cytokines such as interleukin 17 (IL-17) can induce cancer cell proliferation, metastasis and immune escape. Although NSCLC immune escape is partly due to the interaction between PD-1 and PD-L1 and PD-L1 expression can be upregulated in cancer cells upon stimulation with IL-17, the underlying mechanism of IL-17-triggered PD-L1 gene transcription in NSCLC cells remains elusive.

Genetically engineered integrated aflatoxin B and deoxynivalenol bispecific nanobody as surrogate antigens for constructed time-resolved immunoassay dual detection methods.

Biosens Bioelectron

January 2025

Key Laboratory of Biology and Genetic Improvement of Oil Crops, Ministry of Agriculture and Rural Affairs, Wuhan, China; Food Safety Research Institute, HuBei University, Wuhan, China. Electronic address:

There is a phenomenon of combined contamination of fungal toxins, of which aflatoxin B (AFB) is the most toxic, and deoxynivalenol (DON) contamination is common. The use of antigens for double or multiple testing of mycotoxins is easy to cause environmental pollution, and surrogate antigens have become necessary. The small molecule and susceptibility to genetic modification of nanobodies can be used to develop alternative antigens for mycotoxins.

Development of a bacteria-nanosapper for the active delivery of ZIF-8 particles containing therapeutic genes for cancer immune therapy.

Acta Pharm Sin B

December 2024

School of Pharmacy, Institute of Hepatology and Metabolic Diseases, Department of Hepatology, the Affiliated Hospital of Hangzhou Normal University, Hangzhou Normal University, Hangzhou 311121, China.

Specific tumor-targeted gene delivery remains an unsolved therapeutic issue due to aberrant vascularization in tumor microenvironment (TME). Some bacteria exhibit spontaneous chemotaxis toward the anaerobic and immune-suppressive TME, which makes them ideal natural vehicles for cancer gene therapy. Here, we conjugated ZIF-8 metal-organic frameworks encapsulating eukaryotic murine interleukin 2 () expression plasmid onto the surface of VNP20009, an attenuated strain with well-documented anti-cancer activity, and constructed a TME-targeted delivery system named /ZIF-8@.
