Hepatocellular carcinoma (HCC) remains a growing global health threat, necessitating the development of precise molecular probes for its prevention, early diagnosis, and treatment. Glypican-3 (GPC3) is highly expressed in various HCC subtypes and exhibits minimal expression in normal liver tissue, making it a promising biomarker for early-stage HCC diagnosis. Herein, we report a novel cyclic peptide molecular probe, 10P3Me, exhibiting high binding affinity for GPC3, with a of 93.

Background: Traditional Chinese medicines (TCMs) have a long-standing history and diverse applications. However, their complex multi-component compositions and intricate mechanisms of action pose significant challenges for modern scientific investigation. Addressing these complexities requires advanced techniques capable of dissecting cellular and molecular interactions with high resolution.

The pre-dimerization of endosome-localized RNA sensor Toll-like receptor 3 (TLR3) is required for its innate recognition, yet how TLR3 pre-dimers are formed and precisely primed for innate activation remains unclear. Here, we demonstrate that endosome-localized self RNA Rmrp directly binds to TLR3 and induces TLR3 dimerization in the early endosome but does not interact with endosome-localized TLR7, TLR8, TLR9 or cytoplasmic RNA sensor RIG-I under homeostatic conditions. Cryo-EM structure of Rmrp-TLR3 complex reveals a novel lapped conformation of TLR3 dimer engaged by Rmrp, which is distinct from the activation mechanism by dsRNA and the specific structural feature at the 3'-end of Rmrp is critical for its functional interaction with TLR3.

Small extracellular vesicles (sEVs) critically orchestrate inter-tissue and inter-organ communications and may play essential roles in heart-tumor interaction. However, whether cancer-secreted sEVs affect the progression of doxorubicin-induced cardiotoxicity (DOXIC) via orchestrating the tumor cell-cardiomyocyte crosstalk has not yet been explored. Herein, we reveal that Doxorubicin (DOX)-treated breast cancer cells secrete sEVs (D-BCC-sEVs) that exacerbate DOX-induced ferroptosis of human iPSC-derived cardiomyocytes (hiCMs).

Abdominal aortic aneurysm (AAA) is a potentially life-threatening vascular condition that currently lacks effective pharmacological treatment. The disease is strongly associated with chronic inflammation, where immune cells like macrophages play a crucial role. Efferocytosis, the process by which apoptotic cells are cleared, is involved in regulating inflammation.

Purpose: We reviewed recent advancements in the characterization of intraductal oncocytic papillary neoplasm (IOPN) of the pancreas, with a specific focus on developments in immunohistochemical markers, molecular pathology, and pathogenic mechanisms over the past ten years (2015-2024). Through comprehensive analysis of current literature, we aimed to elucidate the evolving understanding of IOPN's biological behavior and diagnostic features, while identifying potential areas for future research in this distinctive pancreatic neoplasm.
Methods: English-language articles on IOPN were searched from Pubmed from the first report of IOPN of the pancreas in 2015 to 2024.

Deep learning (DL) has significantly improved the diagnostic accuracy and efficiency of cytopathologists. However, current DL-assisted reading modes have yet to be fully evaluated, and there is limited evidence regarding cytopathologists' preferences and experiences. This study employs a randomized, controlled, four-way crossover design to assess the effectiveness of four different reading modes in cervical cytopathology readings.

Liver fibrosis, a pivotal pathological stage in the progression of chronic liver diseases to cirrhosis and hepatocellular carcinoma is characterized by liver sinusoidal endothelial cell (LSEC) capillarization, oxidative stress imbalance, and cell pyroptosis. Current clinical interventions show limited efficacy in reversing fibrosis, highlighting the urgent need for novel therapeutic strategies. In this study, we developed an L-arginine-loaded melanin-like nanozyme (L-Arg@MeNPs) that targets liver fibrosis through a triple-action mechanism: (1) sustained nitric oxiderelease from L-Arg restores LSEC fenestration, improving sinusoidal permeability; (2) the MeNPs exhibit catalase/superoxide dismutase-mimicking activity to scavenge reactive oxygen species, thereby blocking the NOD-like receptor pyrin domain-containing 3/caspase-1-mediated pyroptosis pathway; and (3) intrinsic photoacoustic/magnetic resonance dual-modal imaging enables real-time therapeutic monitoring.

Research on multimorbidity patterns promotes our understanding of the common pathological mechanisms that underlie co-occurring diseases. Here, we present a protocol to infer multimorbidity clusters in the form of disease topics from large-scale diagnosis data using treeLFA, a topic model based on the Bayesian binary non-negative matrix factorization. We describe steps for installing software, preparing input data, and training the model.

The diagnostic approaches for Hermansky-Pudlak Syndrome (HPS) include genetic sequencing, immunoblotting, electron microscopy (EM), and flow cytometry with mepacrine staining. However, these methods are often impractical for routine clinical use due to high cost, technical complexity, and limited availability. In this study, we evaluated dense granules (DGs) function in HPS mouse models using flow cytometry with mepacrine and FluoZin-3 staining.
