L3-SMI as a predictor of overall survival in oesophageal cancer patients receiving PD-1 inhibitors combined with chemotherapy.

Background: Programmed death ligand-1 (PD-1), as an immunotherapy target, has been increasingly used in tumour therapies. But as reactions and outcomes to PD-1 inhibitors combined with chemotherapy vary individually, it is primarily important to identify an ideal indicator for predicting the therapeutic effectiveness in individual patients. Oesophageal cancer (EC) patients often have difficulty eating due to tumour blockage of the oesophagus, leading to malnutrition and muscle loss.

Dynamic Covalent Prodrug Nanonetworks via Reaction-Induced Self-Assembly for Periodontitis Treatment.

Periodontitis is characterized by dysbiotic biofilms, gingival inflammation, and bone resorption, highlighting the urgent need for a comprehensive approach to drug combination therapy. In this study, we introduce dynamic covalent nanonetworks (dcNNWs) synthesized through a one-pot, four-component reaction-induced self-assembly method using polyamines, 2-formylphenylboronic acid, epigallocatechin gallate, and alendronate. The formation of iminoboronate bonds drives the creation of dcNNWs, allowing controlled release in the periodontitis microenvironment.

AdipoRon mitigates liver fibrosis by suppressing serine/glycine biosynthesis through ATF4-dependent glutaminolysis.

AdipoRon has been validated for its ability to reverse liver fibrosis, yet the underlying mechanisms remain to be thoroughly investigated. Collagen, predominantly synthesized and secreted in hepatic stellate cells (HSCs), relies on glycine as a crucial constituent. Activating transcription factor 4 (ATF4) serves as a pivotal transcriptional regulator in amino acid metabolism.

Hypoxia-Induced and Glucuronic Acid-Modified Extracellular Vesicles from Mesenchymal Stromal Cells Treat Pulmonary Arterial Hypertension by Improving Vascular Remodeling.

Achieving precise delivery of extracellular vesicles (EVs) to treat pulmonary arterial hypertension (PAH) remains challenging. Here, we propose a strategy using hypoxia-induced and glucuronic acid (GA)-modified mesenchymal stromal-cell-derived EVs (MSC-EVs) to enhance their functionalities and therapeutic targeting. The hypoxia-induced EVs (Hypo-EVs) exhibit enriched exosomal signatures and display heightened inhibition of the proliferation of pulmonary arterial smooth muscle cells (PASMCs) compared to normoxic EVs (Norm-EV).

Lysophosphatidylcholine 14:0 Alleviates Lipopolysaccharide-Induced Acute Lung Injury via Protecting Alveolar Epithelial Barrier by Activation of Nrf2/HO-1 Pathway.

Chondrogenic commitment of human umbilical cord blood and umbilical cord-derived mesenchymal stem cells induced by the supernatant of chondrocytes: A comparison study.

Background: Native cartilage has low capacity for regeneration because it has very few progenitor cells. Human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) and human umbilical cord-derived MSCs (hUC-MSCs) have been employed as promising sources of stem cells for cartilage injury repair. Reproduction of hyaline cartilage from MSCs remains a challenging endeavor.

Novel affibody molecules targeting the AXL extracellular structural domain for molecular imaging and targeted therapy of gastric cancer.
