Discovery of novel natural-product-derived mutant isocitrate dehydrogenases 1 inhibitors: Structure-based virtual screening, biological evaluation and structure-activity relationship study.

Mutations in IDH1 are commonly observed across various cancers, causing the conversion of α-KG to 2-HG. Elevated levels of 2-HG disrupt histone and DNA demethylation processes, promoting tumor development. Consequently, there is substantial interest in developing small molecule inhibitors targeting the mutant enzymes.

Predictive value of arterial blood lactate/serum albumin ratio for myocardial injury in elderly patients with severe community-acquired pneumonia.

To investigate the predictive value of arterial blood lactate (Lac)/serum albumin (Alb) ratio (Lac/Alb) on myocardial injury in elderly patients with severe community-acquired pneumonia (SCAP).Seventy-two elderly SCAP patients hospitalized in the intensive care unit (ICU) of the emergency department of Hebei General Hospital from March 2020 to March 2021 were included, and the general data and arterial blood Lac and serum Alb levels were collected, and Lac/Alb values were calculated. The patients were divided into myocardial injury group (n = 25) and nonmyocardial injury group (n = 47) according to whether the myocardial injury occurred during their ICU stay, and the predictive value of Lac/Alb on myocardial injury in elderly patients with SCAP was assessed using receiver operating characteristic curve and area under the curve.

Regulation of Blood Glucose Using Islets Encapsulated in a Melanin-Modified Immune-Shielding Hydrogel.

Islet transplantation is currently a promising treatment for type 1 diabetes mellitus. However, the foreign body reaction and retrieval difficulty often lead to transplantation failure and hinder the clinical application. To address these two challenges, we propose a balanced charged sodium alginate-polyethyleneimine-melanin (SA-PEI-Melanin) threadlike hydrogel with immune shielding and retrievable properties.

SOX11 and FAK participate in the stretch‑induced mechanical injury to alveolar type 2 epithelial cells.

The aim of the present study was to explore the potential role of SOX11 in the stretch‑induced mechanical injury to alveolar type 2 epithelial (AT2) cells. A cell stretch (CS) test was used to induce mechanical injury to primary cultured AT2 cells. Wound healing, adhesion, cell viability assays and flow cytometry were performed to evaluate the migration, adhesion, viability and apoptosis of AT2 cells.

Enhancement of FAK alleviates ventilator-induced alveolar epithelial cell injury.

Mechanical ventilation induces lung injury by damaging alveolar epithelial cells (AECs), but the pathogenesis remains unknown. Focal adhesion kinase (FAK) is a cytoplasmic protein tyrosine kinase that is involved in cell growth and intracellular signal transduction pathways. This study explored the potential role of FAK in AECs during lung injury induced by mechanical ventilation.

Transfection of Sox11 plasmid alleviates ventilator-induced lung injury via Sox11 and FAK.

Background Ventilator-induced lung injury (VILI) is the most common complication in the mechanical ventilation in clinic. The pathogenesis of VILI has not been well understood. The SRY related High Mobility Group box group-F family member 11(Sox11) is a protein associated with lung development.
