Cells release extracellular vesicles (EVs) as the carriers for intercellular communications to regulate life activities. Particularly, it is increasingly apparent that mechanical forces play an essential role in biological systems. The nanomechanical properties of EVs and their dynamics cancer development are still not fully understood. Herein, with use atomic force microscopy (AFM), signatures from liquid biopsies hematologic patients were unraveled. Single native probed by AFM under...

The cancer-associated fibroblast (CAF) barrier in pancreatic ductal adenocarcinoma (PDAC) greatly restricts clinical outcomes. Major obstacles to PDAC treatment include restricted immune cell infiltration and drug penetration the immunosuppressive microenvironment. Here, we reported a "shooting fish barrel" strategy by preparing lipid–polymer hybrid delivery system (PI/JGC/L-A) that could overcome CAF turning it into "barrel" with antitumor depot properties alleviate microenvironment...

In the course of both innate and adaptive immunity, cytidine deaminases within activation induced deaminase (AID)/apolipoprotein B editing complex (APOBEC) family modulate immune responses by mutating specific nucleic acid sequences hosts pathogens. The evolutionary emergence these mediators, however, seems to coincide precisely with immunity in vertebrates. Here, we show a genes species two divergent invertebrate phyla-the echinoderm Strongylocentrotus purpuratus brachiopod Lingula...

Abstract Uric acid crystal is known to activate the NLRP3 inflammasome and cause tissue damages, which can result in many diseases, such as gout, chronic renal injury myocardial damage. Meanwhile, soluble uric (sUA), before forming crystals, also related these diseases. This study was carried out investigate whether sUA could cardiomyocytes analyse mechanisms. The cardiomyocyte activity monitored, along with levels of mature IL‐1β caspase‐1 from H9c2 cells following stimulus. We found that...

Abstract Tumor immune escape caused by low levels of tumor immunogenicity and checkpoint‐dependent suppression limits the immunotherapeutic effect. Herein, a “two‐way regulation” epigenetic therapeutic strategy is proposed using novel nano‐regulator that inhibits upregulating expression tumor‐associated antigens (TAAs) to improve downregulating programmed cell death 1 ligand (PD‐L1) block death‐1 (PD‐1)/PD‐L1. To engineer nano‐regulator, DNA methyltransferase (DNMT) inhibitor zebularine...

Glioblastoma stem cells (GSCs) are pivotal in the recurrence and drug resistance of glioblastoma multiforme (GBM). However, precision therapeutic diagnostic markers for GSCs have not been fully established. Here, using bioinformatics experimental analysis, we identified P4HB, a protein disulfide isomerase, as serum marker that maintains stemness through Wnt/β-catenin signaling pathway. Transcriptional silencing P4HB induces apoptosis diminishes cell-like characteristics GSCs. Treatments with...

Abstract Vasculogenic mimicry (VM) is an endothelium-independent tumor microcirculation that provides adequate blood supply for growth. The presence of VM greatly hinders the treatment glioblastoma (GBM) with anti-angiogenic drugs. Therefore, targeting formation may be a feasible therapeutic strategy GBM. research aimed to evaluate roles BUD13, CDK12, MBNL1 in regulating BUD13 and CDK12 were upregulated was downregulated GBM tissues cells. Knockdown or overexpression inhibited formation....

<title>Abstract</title> Glioblastoma (GBM), the most aggressive and treatment-resistant form of brain cancer, is significantly influenced by GBM stem cells (GSCs), which contribute to tumor initiation recurrence. In this study, we introduce two novel proteolysis-targeting chimeras (PROTACs), AN-1 AN-2, engineered degrade BCL-X<sub>L</sub>, a critical anti-apoptotic protein in BCL-2 family. These PROTACs are optimized from ABT-263 uniquely utilize MDM2 as an E3 ligase, strategy not previously...
