Objective: To investigate the binding characteristics of endothelial cell (EC) with LPS free from the participation of serum factors.
Methods: Laser confocal microscope was employed in the observation of the binding of EC with FITC-LPS. The KD and the binding sites of each EC were calculated by radioligand binding assay of receptors (RBA) using [(3)H]-LPS.
Results: The binding of EC with LPS was saturable, time and concentration dependent and it could be competed with overdosed LPS of the same type. The fluorescence mainly distributed in cytoplasm, especially near the nucleus, which could also be stained.
Conclusions: There might be some specific LPS binding sites existing on ECs and LPS could function intracellularily.

Guvermectin, a purine nucleoside natural product produced by the genus S, has recently been registered as a new biopesticide to boost rice yield. Despite its economic and agricultural significance, the regulatory mechanisms of guvermectin biosynthesis remain essentially unknown, hindering industrial production and widespread agricultural application. Here, we examined the roles of two LacI family regulators, and , located within and adjacent to the guvermectin biosynthesis cluster, respectively, in guvermectin production in NEAU6.

Objective: The Heat Shock Protein 70 (HSP70) family is a highly conserved group of molecular chaperones essential for maintaining cellular homeostasis. These proteins are necessary for protein folding, assembly, and degradation and involve cell recovery from stress conditions. HSP70 proteins are upregulated in response to heat shock, oxidative stress, and pathogenic infections.

The conformational dynamics and activation mechanisms of KRAS proteins are of great importance for targeted cancer therapy. However, the detailed molecular mechanics of KRAS activation induced by GTP binding remains unclear. In this study, we systematically investigated how GTP/GDP exchange affects the thermodynamic and kinetic properties of KRAS and explored the activation mechanism using molecular dynamics (MD) simulations, Markov state models (MSMs), and neural relational inference (NRI) models.

Ethylene oxide (EO) and propylene oxide (PO) are widely used as sterilizing agents in the food industry. However, their residues in food packaging can migrate into food and react with it, affecting the accuracy of residue detection in food. This study aims to explore the reaction mechanisms between EO and PO and aqueous food simulants using both experimental and computational methods.
