Hum Cell

January 2025

Department of Nephrology, Zhong Da Hospital, Gulou District, No. 87, Dingjiaqiao, Zhongyangmen Street, Nanjing, 210009, Jiangsu, China.

Autophagy, a cellular degradation process involving the formation and clearance of autophagosomes, is mediated by autophagic proteins, such as microtubule-associated protein 1 light chain 3 (LC3) and sequestosome 1 (p62), and modulated by 3-methyladenine (3-MA) as well as chloroquine (CQ). Senescence, characterised by permanent cell cycle arrest, is marked by proteins such as cyclin-dependent kinase inhibitor 1 (p21) and tumour protein 53 (p53). This study aims to investigate the relationship between cell senescence and renal function in diabetic kidney disease (DKD) and the effect of autophagy on high-glucose-induced cell senescence.

Glomerular endothelial cells (GECs) are pivotal in developing glomerular sclerosis disorders. The advancement of focal segmental glomerulosclerosis (FSGS) is intimately tied to disruptions in lipid metabolism. Sphingosine-1-phosphate (S1P), a molecule transported by high-density lipoproteins (HDL), exhibits protective effects on vascular endothelial cells by upregulating phosphorylated endothelial nitric oxide synthase (p-eNOS) and enhancing nitric oxide (NO) production.

On-site visual quantification of alkaline phosphatase activity in cells using a smartphone-based approach.

Anal Chim Acta

January 2025

Hunan Provincial Key Laboratory of Cytochemistry, School of Chemistry and Chemical Engineering, Changsha University of Science and Technology, Changsha, 410114, PR China.

Alkaline phosphatase (ALP) is a critical biomarker associated with various physiological and pathological processes, making its detection essential for disease diagnosis and biomedical research. In this study, we developed a novel, simple, and portable visual quantification method for ALP activity in cells using an efficient CuZnS nanomaterial with peroxidase-like properties, integrated into a smartphone-based platform for enhanced usability. The CuZnS nanomaterial catalyzes the breakdown of H₂O₂, generating ·OH radicals that oxidize the colorless substrate TMB into blue oxTMB, which is subsequently reduced back to TMB by ascorbic acid (AA).

Interferon regulatory factor 4 (IRF4) is specifically overexpressed in multiple myeloma (MM) and mediates MM progression and survival, making it an emerging target for MM treatment. However, no chemical entity with a defined structure capable of directly binding to and inhibiting IRF4 has been reported. We screened our small library of steroid analogs and identified bisnoralcohol (BA) derivative 18 as a novel hit compound capable of inhibiting IRF4, with an IC of 13.

A signaling molecule from intratumor bacteria promotes trastuzumab resistance in breast cancer cells.

Proc Natl Acad Sci U S A

January 2025

Key Laboratory of Molecular Nanostructure and Nanotechnology, Research/Education Center for Excellence in Molecular Sciences, Institute of Chemistry, Chinese Academy of Sciences, Beijing 100190, China.

Emerging evidence indicates that intratumor bacteria exist as an active and specific tumor component in many tumor types beyond digestive and respiratory tumors. However, the biological impact and responsible molecules of such local bacteria-tumor direct interaction on cancer therapeutic response remain poorly understood. Trastuzumab is among the most commonly used drugs targeting the receptor tyrosine-protein kinase erbB-2 (ErbB2) in breast cancer, but its resistance is inevitable, severely limiting its clinical effectiveness.

Arachidonic acid synergizes with aspirin preventing myocardial ischemia-reperfusion injury and mitigates bleeding risk.

Cardiovasc Res

January 2025

State Key Laboratory of Cardiovascular Disease, Clinical Pharmacology Center, Fuwai Hospital, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, 100037, China.
