HucMSC-Ex alleviates inflammatory bowel disease by regulating O-GlcNAcylation modification of RACK1 in intestinal epithelial cells.

Inflammatory Bowel Disease (IBD) is a chronic autoimmune disorder that severely affects the gastrointestinal tract and is difficult to cure. This study explored the mechanism by which human umbilical cord mesenchymal stem cell-derived exosomes (HucMSC-Ex) alleviate IBD through O-GlcNAc glycosylation modification and the expression of related proteins. The study analyzed the effects of HucMSC-Ex on the inhibition of pro-inflammatory factors and promotion of intestinal epithelial cells regeneration in vitro and in vivo, with a focus on the role of the O-GlcNAc glycosylation of the RACK1 protein.

Expression, regulation, function and clinical significance of B7-H6 on neutrophils in human gastric cancer.

Neutrophils are conspicuous components of gastric cancer (GC) tumors, increasing with tumor progression and poor patient survival. However, the phenotype, regulation, function and clinical relevance of neutrophils in human GC are presently unknown. We used flow cytometry analyses to examine levels and phenotype of neutrophils in samples from 50 patients with GC.

Machine learning-based identification of high-risk bone metastasis factors after radical prostatectomy in prostate cancer.

Background: Bone metastasis is a serious complication following radical prostatectomy in prostate cancer patients, significantly affecting their long-term survival. This study aims to develop a clinical predictive model utilizing Magnetic Resonance Imaging (MRI) and advanced machine learning algorithms to identify key factors that increase the risk of bone metastasis (BM).

Patients And Methods: The study analyzed a cohort of 1161 prostate cancer patients, including 38 who developed bone metastasis.

From morphology to single-cell molecules: high-resolution 3D histology in biomedicine.

High-resolution three-dimensional (3D) tissue analysis has emerged as a transformative innovation in the life sciences, providing detailed insights into the spatial organization and molecular composition of biological tissues. This review begins by tracing the historical milestones that have shaped the development of high-resolution 3D histology, highlighting key breakthroughs that have facilitated the advancement of current technologies. We then systematically categorize the various families of high-resolution 3D histology techniques, discussing their core principles, capabilities, and inherent limitations.

Extracellular TatD from Listeria monocytogenes displays DNase activity and contributes to biofilm dispersion.

TatD is evolutionarily conserved in a variety of organisms and has been implicated in DNA repair, apoptosis, and the disruption of extracellular traps. The aim of our study was to investigate the effects of TatD on L. monocytogenes biofilms.
