Summary: In this study, a high yield of recombinant CD20 and claudin 18.2 proteins was achieved using an in vitro coupled transcription-translation system. The results showed that rituximab has a high affinity with CD20 protein. This study provides a novel concept for promoting the expression of multi-pass transmembrane proteins and lays the foundation for large-scale industrial production of membrane-associated drug targets.

Summary: Protein Tyrosine Phosphatase 1B (PTP1B) is a negative regulator of insulin signaling pathways and has potential as a medicinal target. This study explores the binding and conformational orientation of zinc(II) complexes in PTP1B using advanced computational methods. The findings suggest that zinc(II) complexes can bind to important residues in the enzyme and inhibit its activity.

Summary: Fragment-based drug design is a computer-aided drug discovery method, however, it has limitations in processing time and success rate. In this study, a new method called Fragment Databases from Screened Ligands Drug Design (FDSL-DD) was proposed, which intelligently incorporates fragment characteristics into the drug design process to improve the binding affinity between drugs and protein targets.

Summary: This study evaluated the use of solid medium in sterility testing. Results showed that the sterility test using Schaedler blood agar (SBA) was more sensitive and faster in detecting microorganisms compared to the current compendial method, particularly in samples containing thimerosal. The sterility test using solid medium could be completed in 7 days without any additional technology.

Summary: A meeting was held in February 2023 by international organizations to discuss correlates of protection against COVID-19, reviewing evidence and identifying knowledge gaps. Neutralizing antibodies and T lymphocytes are believed to play a significant role in protection, but further studies are needed to consolidate the evidence and evaluate other potential factors.

Summary: This study focused on a halophilic archaeal nitrile hydratase (NHase) and found that it exhibited higher tolerance to substrates and products compared to NHases from other sources. The unique genetic structure of this highly stable archaeal NHase could provide a theoretical foundation for modifying and enhancing the industrial application of NHase.

Summary: This study reports an expression, refolding, and purification method for antibody-mimetic drug conjugate (AMDC). The AMDC uses a variable heavy chain of heavy chain-only antibodies (VHHs) as the targeting protein and non-covalently binds to a potent DNA-alkylating drug. The AMDC shows strong cytotoxic effects on cancer cells.

Summary: Pompe disease is a lysosomal storage disorder characterized by glycogen accumulation in skeletal muscle, leading to profound pathology. This study showed that lentiviral gene therapy with LV-IGF2.GAAco can nearly completely correct disease-associated proteomic changes, supporting its future clinical development as a new treatment option for Pompe disease.

Summary: A prognostic model of BC based on LNM-related genes was established in this study, providing guidance for prognosis evaluation and precise treatment of BC. The genes related to lymph node metastasis in BC are largely unknown and need further exploration. Searching for potential lymph node metastasis-related genes of BC will provide meaningful biomarkers for BC treatment. Our model, based on TCGA-BRCA data, effectively predicted patient outcomes and classified BC patients. The identified feature genes might have a predictive function in immunotherapy. The results of this study provide a new reference for the prognosis and treatment of BC patients with lymph node metastasis.

Summary: This study fills the knowledge gap about the matrix proteins involved in the formation of mineralized exoskeletons in decapod crustaceans. By comparing with well-studied molluscan biomineralization proteins, it is proposed that decapod crustaceans evolved novel proteins while sharing some proteins with molluscs. This study provides insights into the evolution and adaptation of crustaceans and molluscs in forming their exoskeletons.

Summary: This study compared the results of different methods for measuring the amount of acetyl-Coenzyme A. The colorimetric ELISA kit did not produce interpretable results, while the fluorometric enzymatic kit showed comparable results to the LC-MS-based methods depending on the matrix and extraction conditions. LC-MS/MS and LC-HRMS methods produced well-aligned results, especially when using stable isotope-labeled internal standards.

Summary: To address environmental issues caused by traditional plastics, bioplastics have gained attention as alternatives. Although bioplastics have better degradability, their degradation still takes longer than anticipated. This study proposes a novel screening method to identify bioplastic degraders faster, saving time and providing more quantitative data.
