Protease 3075, a novel enzyme from thermophilic Cohnella sp. A01, was characterized through recombinant production in E. coli BL21. It exhibits optimal activity at 70°C and pH 6, with enhanced stability in the presence of Tween 80 and acetone. Docking and molecular dynamics simulations revealed hydrogen bonds and Van der Waals forces stabilize the enzyme-Tween 80 interaction, increasing structural stability. The enzyme shows potential for industrial applications, particularly in detergents.

C57BL/J6 male mice were used for metabolomics and isotope-labeled MTA analysis under anesthesia. MTA was injected to examine blood–brain barrier crossing. Surgery experiments exposed the left carotid artery, and MTA rescue experiments were conducted. Metabolomics processing involved LC-MS/MS, PCA, PLS-DA, and OPLS-DA. snRNA-seq libraries were generated for single-cell analysis. Joint pathway analysis used O2PLS and MetaboAnalyst 5.0. Western blotting and ELISA assessed protein and cytokine levels. Behavioral tests included open field and Barnes maze tests. A clinical investigation evaluated cognitive decline post-surgery in humans, with serum samples analyzed by LC-MS/MS. Statistical methods included Student’s t-test, ANOVA, and ROC curve analysis.

Study details the experimental model and subject details for five cases of isolated PM-ccRCC, including patient inclusion/exclusion criteria, sample transport, processing, and cell culture optimization. The study also covers exome sequencing, mutation and CN analysis, single-cell RNA sequencing, drug sensitivity and resistance testing, immunostainings, pathway analysis, and ethical approvals. Statistical analysis and reproducibility are discussed, with results compared between PM-ccRCC DSRT data and previously published ccRCC DSRT data.

Detailed experimental protocols for Droplet Hi-C and Paired Hi-C, including fixation, in situ Hi-C, and single-cell sequencing library construction, are described. Data processing and analysis methods for Droplet Hi-C data, such as demultiplexing, mapping, and extracting single-cell contacts, are outlined. The article also covers the analysis of chromatin interactions, compartments, domains, loops, and multi-way interactions, as well as the identification of structural variations (SVs) and extrachromosomal DNA (ecDNA) candidates. Ethical approval for specimen collection is noted.
