Squamocin Suppresses Tumor Growth through Triggering an Endoplasmic Reticulum Stress-Associated Degradation of EZH2/MYC Axis.

Despite substantial advances in the antitumor effects of annonaceous acetogenins (ACGs), the absence of a defined biological action mechanism remains a major barrier to their clinical application. Here, it is found that squamocin effectively depletes both EZH2 and MYC in multiple cancer cell lines, including head and neck squamous cell carcinoma, and gastric and colorectal cancer, demonstrating potent efficacy in suppressing these in vivo tumor models. Through the combination of surface plasmon resonance (SPR), differential scanning fluorimetry (DSF), and cellular thermal shift assay (CETSA), heat shock protein 90α (HSP90α) is identified as the direct binding target of squamocin.

Multidimensional Resonance Controlled by Critical Size in Printed Binary Colloidal Crystals for High-Contrast Imaging.

Colloidal crystal engineering enables the precise construction of structures with remarkable properties. However, the flexible and synergistic regulation of multiple properties of colloidal crystals remains a significant challenge. Here, we inspire from Brazilian opals to self-assemble polymer nanoparticles in the gaps of a single-layer opal substrate to fabricate large-scale binary colloidal crystals (BCCs).

Risk factors for chronic postsurgical pain following thoracoscopic surgery for lung cancer.

Objective: Chronic post-surgical pain (CPSP) following thoracoscopic lung cancer surgery is a common and challenging complication. Identifying risk factors and predictive markers is essential for improving patient outcome.

Methods: In this retrospective case-control study, the clinical data from 106 patients with non-small cell lung cancer (NSCLC) who underwent thoracoscopic radical resection between January 2021 and December 2023 were comprehensively analyzed.

Clinical value of metagenomic sequencing in system evaluation of potential donors and donor-derived infection in kidney transplantation.

Objective: To explore the application and the clinical value of metagenomic sequencing in system evaluation of potential kidney donors, along with donor-derived infection in kidney transplantation.

Methods: A prospective study was conducted on 40 voluntary renal donors in Ningbo Urology and Kidney Disease hospital from January 2021 to August 2023. The results of donor pathogen fed back by metagenomic sequencing were analyzed to understand the clinical significance of metagenomic sequencing in donor evaluation.

Investigating the Role of Quercetin, an Active Ingredient in Bazhen Decoction, in Targeting CXCL8 to Inhibit Macrophage M2 Polarization and Reshape the Immunological Microenvironment of Colorectal Cancer.

Bazhen Decoction (Eight Treasures Decoction) has demonstrated efficacy in the treatment of colorectal cancer (CRC), yet the active ingredients in it and the mechanisms underlying their anti-cancer properties are not well understood. Through network pharmacology, the effective components of Bazhen Decoction against CRC and their corresponding key genes were delineated. Molecular docking was executed to identify the active component targeting the key gene CXCL8, which led to the discovery of Quercetin.
