AI Article Synopsis

  • The study investigates the formation of a stable protein corona using human α-1-acid glycoprotein (AGP) and citrate-stabilized silver nanoparticles (Ag-CIT), highlighting its significance in cellular responses to nanoparticles.
  • The molecular docking simulations and experimental techniques demonstrated a strong interaction, with a high binding constant of 10 M, indicating AGP's ability to form a robust bioconjugate with the nanoparticles.
  • Importantly, the formation of this AGP corona maintains the protein's native structure and reduces the cytotoxic effects of silver nanoparticles, enhancing their biocompatibility.

Article Abstract

Given the importance of protein corona in determining cellular responses to nanoparticles, numerous studies have been devoted to finding stable, biocompatible, and nontoxic protein corona. In this work, the interaction between human α-1-acid glycoprotein (AGP) and citrate-stabilized silver (Ag-CIT) nanoparticles of about 10 nm was methodically studied using molecular docking simulation approach and various experimental techniques. It could be shown that a stable Ag-CIT/AGP bioconjugate was formed with a high binding constant of 10 M, several orders of magnitude larger than that of other highly abundant serum proteins. Formation of AGP corona was accompanied by conserving the native conformation of the protein and further associated with a considerable decrease in the cytotoxicity of the silver nanoparticles.

Mineralizing cells release a special class of extracellular vesicles known as matrix vesicles (MV), crucial for bone mineralization. Following their release, MV anchor to the extracellular matrix (ECM), where their highly specialized enzymatic machinery facilitates the formation of seed mineral within the MV's lumen, subsequently releasing it onto the ECM. However, how MV propagate mineral onto the collagenous ECM remains unclear.

Among the various types of pancreatic cancers, pancreatic ductal adenocarcinoma (PDAC) is the most lethal and aggressive, due to its tendency to metastasize quickly and has a particularly low five-year survival rate. Carbohydrate antigen 19-9 (CA 19-9) is the only biomarker approved by the Food and Drug Administration for PDAC and has been a focal point in diagnostic strategies, but its sensitivity and specificity are not sufficient for early and accurate detection. To address this issue, we introduce a synergistic approach combining CA 19-9 levels with a graphene oxide (GO)-based blood test.

Protein-nanoparticle interactions and the resulting corona formation play crucial roles in the behavior and functionality of nanoparticles in biological environments. In this study, we present a comprehensive analysis of protein corona formation with superfolder green fluorescent protein (sfGFP) and bovine serum albumin in silica nanoparticle dispersions using small-angle X-ray scattering (SAXS) and dynamic light scattering (DLS). For the first time, we subtracted the scattering of individual proteins in solution and individual nanoparticles from the protein-nanoparticle complexes.

In recent years, the chiral biological effects of nanomedicines have garnered significant interest. Research has focused on understanding how material chirality affects cellular transcription and metabolism. Stress granules, which are membraneless organelles formed through liquid-liquid phase separation of G3BP1 proteins and related compartments, have been extensively studied and are closely associated with cellular damage repair and metabolism.
