Water-Soluble Fluorescent Sensors for Quantification of Trace Cisplatin in Body Fluids from Clinical Cancer Patients.

Accurate quantification of cisplatin (cDDP) in body fluids (blood, urine, and ascites) is crucial in monitoring therapeutic processes, assessing drug metabolism, and optimizing treatment schedules for cancer patients. Nonetheless, due to the inherent fluorescence and complexity of the body fluid matrix, along with the low cDDP concentrations in these fluids during treatment, using fluorescent sensors for fluid detection remains a subject of ongoing research. Herein, a series of water-soluble cDDP-activatable fluorescent sensors was rationally constructed by introducing thioether groups to the xanthene skeleton based on the chalcogenophilicity of platinum.

Hydrogelation of peptides and carnosic acid as regulators of adaptive immunity against postoperative recurrence of cutaneous melanoma.

The in-situ activation of adaptive immunity at the surgical site has demonstrated remarkable efficacy in inhibiting various forms of tumour recurrence and even holds the promise of a potential cure. However, extensive research and bioinformatic analysis conducted in this study have unveiled the formidable challenge posed by melanoma-intrinsic β-catenin signaling, which hinders the infiltration of cytotoxic T-lymphocytes (CTLs) and their subsequent anti-tumour action. To overcome this obstacle, a β-catenin antagonist called carnosic acid (CA) was co-assembled with a RADA-rich peptide to create a nanonet-derived hydrogel known as Supra-gelδCA.

Ball-Milling-Enabled Nickel-Catalyzed Reductive 1,4-Alkylarylation of 1,3-Enynes under an Air Atmosphere.

A ball-mill-enabled nickel-catalyzed 1,4-alkylarylation of 1,3-enynes with organic bromides has been developed, offering a versatile method for assembling tetrasubstituted allenes. This approach, the first of ball-milling-based remote radical coupling, overcomes the limitations of traditional solution-phase methods, such as the need for air- and moisture-sensitive reagents, the use of bulk solvents, and prolonged reaction times. Given the outstanding performance of ball-milling-based radical reduction coupling reactions, we anticipate further advancements in sustainable and efficient synthetic methodologies.

Appendicectomy has been the optimal treatment of acute appendicitis, yet the cancer incidence after appendix removal remains unclear. In this territory-wide retrospective cohort study, adult participants who underwent appendicectomy from 2000 to 2018 were retrieved from a population database (n = 43,983), while matched reference participants were retrieved as controls (n = 85,853).

Dual therapy with phospholipase and metalloproteinase inhibitors from Sinonatrix annularis alleviated acute kidney and liver injury caused by multiple snake venoms.

Snakebite envenomation often induces acute kidney injury (AKI) and acute liver injury (ALI), leading to augmented injuries and poor rehabilitation. Phospholipase A (PLA) and metalloproteinase (SVMP) present in venom are responsible for the envenomation-associated events. In this study, mice envenomed with Deinagkistrodon acutus, Naja atra, or Agkistrodon halys pallas venom exhibited typical AKI and ALI symptoms, including significantly increased plasma levels of myoglobin, free hemoglobin, uric acid, aspartate aminotransferase, and alanine aminotransferase and upregulated expression of kidney NGAL and KIM-1.

Reversing MET-Mediated Resistance in Oncogene-Driven NSCLC by MET-Activated Wnt Condensative Prodrug.

The amplification of MET is a major cause of acquired resistance to targeted therapy in EGFR-mutant non-small-cell lung cancer (NSCLC), only to be temporarily restrained by the partial efficacy of MET inhibitors. This study reveals that the MET inhibitor has unexpectedly limited efficacy due to amplified MET triggering a strong positive feedback loop in the Wnt/β-catenin signaling pathway, allowing optimal functionality even when the MET pathway is suppressed again. To test this conjecture and specifically target the Wnt/β-catenin pathway, a cleverly designed Wnt condensative pro drug called WntSI is developed using reversible supramolecular self-assembly driven by liquidliquid phase separation (LLPS).

Interleukin-6 trans-signaling regulates monocyte chemoattractant protein-1 production in immune-mediated necrotizing myopathy.

Objective: Immune-mediated necrotizing myopathy (IMNM) is pathologically characterized by diffuse myofiber necrosis and regeneration, myophagocytosis, and a sparse inflammatory infiltrate. The monocyte chemoattractant protein-1 (MCP-1) is a key chemokine that regulates monocyte/macrophage infiltration into injured tissues. The interleukin-6 (IL-6) signalling in the induction of MCP-1 expression has not been investigated in IMNM.

Advancing the Boundaries of Immunotherapy in Lung Adenocarcinoma with Idiopathic Pulmonary Fibrosis by a Biomimetic Proteinoid Enabling Selective Endocytosis.

The coexistence of lung adenocarcinoma (LUAD) with idiopathic pulmonary fibrosis (IPF), which has been extensively documented as a prominent risk factor for checkpoint inhibitor-related pneumonitis (CIP) in patients undergoing immunotherapy, has long been considered a restricted domain for the use of immune checkpoint inhibitors (ICIs). To overcome it, an approach was employed herein to specifically target PD-L1 within the cellular interior, surpassing the conventional focus solely on the cytomembrane, thereby facilitating the development of ICIs capable of distinguishing between LUAD cells and noncancerous cells based on their distinctive endocytic propensities. By exploiting the aurophilicity-driven self-assembly of a PD-L1 binding peptide (PDBP) and subsequently encapsulating it within erythrocyte membranes (EM), the resulting biomimetic ICIs protein EMS-PDBP exhibited extraordinary selectivity in internalizing LUAD cells, effectively targeting PD-L1 within cancer cells while hindering its membrane translocation.
