We studied toxicity of recombinant Streptococcus pneumoniae pneumolysin protein in experiments on mice and its cytopathogenic effect on cultures of Vero green monkey kidney cells and human lung carcinoma A549 cells in vitro. In vivo and in vitro experiments proved the absence of compromised toxicity and direct cytopathogenic action of the recombinant protein.

Background: Liver fibrosis is caused by chronic toxic or cholestatic liver injury. Fibrosis results from the recruitment of myeloid cells into the injured liver, the release of inflammatory and fibrogenic cytokines, and the activation of myofibroblasts, which secrete extracellular matrix, mostly collagen type I. Hepatic myofibroblasts originate from liver-resident mesenchymal cells, including HSCs and bone marrow-derived CD45+ collagen type I+ expressing fibrocytes.

High-dose methotrexate (MTX) results in high rates of acute kidney injury (AKI), neutropenia, and hepatotoxicity. Glucarpidase is a recombinant enzyme that cleaves MTX, but clinical data supporting its use are scarce. We examined the association between glucarpidase administration and outcomes in adults with MTX-AKI from 28 cancer centers across the U.

The Cell-Free Protein Synthesis (CFPS) is an innovative technique used to produce various proteins. It has several advantages, including short expression times, no strain engineering is required, and toxic proteins such as membrane proteins can be produced. However, the most important advantage is that it eliminates the need for a living cell as a production system.

Chinese hamster ovary (CHO)-K1 cells are widely used in biomedical research relevant to cancer, toxicity screening, and viruses, as well as in the production of recombinant proteins for biopharmaceuticals. In this study, liquid chromatography (LC)-electrospray ionization (ESI)-higher energy collisional dissociation (HCD)-tandem mass spectrometry (MS/MS) was used to characterize the surface and lysate N-glycans of CHO-K1 cells and analyze their structures. The relative quantity (%) of each N-glycan and absolute quantity (pmol) of total N-glycans were also obtained.
