Antigen-presenting cells (APCs) process tumor vaccines and present tumor antigens as the first signals to T cells to activate anti-tumor immunity, which process requires the assistance of co-stimulatory second signals on APCs. The immune checkpoint programmed death ligand 1 (PD-L1) not only mediates the immune escape of tumor cells but also acts as a co-inhibitory second signal on APCs. The serious dysfunction of second signals due to the high expression of PD-L1 on APCs in the tumor body results in the inefficiency of tumor vaccines.

January 2025

Department of Surgical Oncology and General Surgery Key Laboratory of Precision Diagnosis and Treatment of Gastrointestinal Tumors, Ministry of Education The First Affiliated Hospital of China Medical University, Shenyang, 110001, China.

Current in vitro models for gastric cancer research, such as 2D cell cultures and organoid systems, often fail to replicate the complex extracellular matrix (ECM) found in vivo. For the first time, this study utilizes a gelatin methacryloyl (GelMA) hydrogel, a biomimetic ECM-like material, in 3D bioprinting to construct a physiologically relevant gastric cancer model. GelMA's tunable mechanical properties allow for the precise manipulation of cellular behavior within physiological ranges.

January 2025

Department of Critical Care Medicine, Affiliated Hospital of Zunyi Medical University, 149 Dalian Road, Huichuan District, Zunyi, Guizhou 563003, China; Guizhou Key Laboratory of Anesthesia and Organ Protection, Zunyi Medical University, Zunyi, Guizhou 563000, China. Electronic address:

Thyroid hormone (TH) and it most active form triiodothyronine (T3) are crucial in promoting mitochondrial biogenesis and maintaining cellular homeostasis during the stress response, but their role in paraquat (PQ)-induced pulmonary fibrosis isunclear. The aim of this study was to examine whether there was a deficiency of TH in mouse lung tissue after PQ administration, and to explore the effect of T3, and potential mechanisms of action, in alleviation of PQ-induced pulmonary fibrosis. We found that the activity and expression of iodothyronine deiodinase 2 (DIO2), an enzyme that activates TH, were higher in the lungs of patients with pulmonary fibrosis than in controls.

Alzheimer's disease (AD), the most prevalent form of dementia in the elderly, involves critical changes such as reduced aerobic glycolysis in astrocytes and increased neuronal apoptosis, both of which are significant in the disease's pathology. In our study, astrocytes treated with amyloid β1-42 (Aβ) to simulate AD conditions exhibited upregulated expressions of small ubiquitin-like modifier (SUMO)-specific protease 1 (SENP1) and Pumilio RNA Binding Family Member 2 (PUM2), alongside decreased levels of Nuclear factor erythroid 2-related factor 2 (NRF2). SENP1 is notably the most upregulated SUMOylation enzyme in Aβ-exposed astrocytes.

Ethnopharmacological Relevance: Shexiang Baoxin Pill (MUSKARDIA), a traditional Chinese patent medicine, plays a crucial role in both preventing and treating diverse cardiovascular diseases, including coronary heart disease, myocardial infarction (MI), and heart failure. Preclinical research has demonstrated that the cardioprotective effects of MUSKARDIA are achieved through multiple pathways, such as enhancing coronary artery dilation, fostering new blood vessel growth, reducing inflammation and oxidative stress, improving lipid metabolism, and protecting vascular endothelium.

Aim Of The Study: This subgroup analysis aimed to evaluate the efficacy and safety of Shexiang Baoxin Pill (MUSKARDIA) plus optimal medical therapy (OMT) across different weight categories in treating stable coronary artery disease (CAD).

Key Laboratory of Cell Biology, Department of Cell Biology, Ministry of Public Health and Key Laboratory of Medical Cell Biology, Ministry of Education, School of Life Sciences, China Medical University, Shenyang, Liaoning 110122, China. Electronic address:

Glutamine, akin to glucose, is a fundamental nutrient for human physiology. Tumor progression is often accompanied by elevated glutamine consumption, resulting in a disrupted nutritional balance and metabolic reprogramming within the tumor microenvironment. Furthermore, immune cells, which depend on glutamine for metabolic support, may experience functional impairments and dysregulation.
