Photothermal therapy (PTT) is a potentially advanced strategy for highly precise cancer treatment. Tumor-microenvironment-activatable agents provide useful tools for PTT, but their photothermal conversion capacities vary and cannot be evaluated in vivo; thus, a general PTT prescription does not work with individual activatable agents. Here, glutathione (GSH)-activatable nanocomposites, silicomolybdate-functionalized NaLuF :Yb,Er@NaLuF @NaLuF :Nd are prepared, for customized PTT of subcutaneous orthotopic cancer. By simultaneously determining intratumoral GSH concentration and the amount of accumulated agent using multiple orthogonal luminescent emissions of nanocomposites, near-infrared absorbance of photothermal conversion agents is evaluated in vivo, based on the optimized irradiating prescriptions (irradiating power density and time) established. This allows customized PTT of each individual case with high efficacy and viability. This work also includes a method for investigating individual intratumoral variation, and the development of the next generation of customized nanomedicine for efficacious PTT of subcutaneous orthotopic cancer.

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.

Hepatic carcinoma is one of the most common malignancies with low survival rates due to insufficient therapeutics while early detection of hepatic tumors remains key to reducing mortality of liver cancer. However, current clinical methods are hard to detect pathological changes in early-stage cases while the detection rate of liquid biopsy-based assay is limited. Thus, effective tools for accurate and sensitive detection of hepatic tumors are still in urgent need.

This study aimed to utilize the mRNA-lipid nanoparticle (mRNA-LNP) platform to achieve in situ hepatic expression of an interferon-α (IFN-α)/anti-glypican-3 (anti-GPC3) fusion protein (GPA01), enhancing IFN-α targeting and antitumor activity to provide a precision therapy strategy for GPC3-positive hepatocellular carcinoma (HCC). mRNA encoding a GPC-3/IFN-α bispecific fusion protein was designed and synthesized, encapsulated in lipid nanoparticles, and transfected into HCC cell lines (HepG2) for in vitro characterization of protein expression, binding activity, and gene induction. Orthotopic HCC models (HepG2-luc) and subcutaneous tumor model (Hepa 1-6/hGPC3-hi) were established in mice to evaluate tumor growth, survival, and immune cell infiltration following treatment with mRNA-LNP or control agents.

The necessity of reliable preclinical models for evaluating the efficacy of novel therapeutic strategies is imperative. Nevertheless, the degree to which tumor-bearing murine models represent the immunological characteristics of human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) has largely been unexplored. Utilizing single-cell RNA sequencing technology, our research elucidated that subcutaneous (SC) murine models more accurately reflect the early immunogenic phase of human HPV-positive OPSCC, marked by a stage-dependent increase in effector T cell infiltration.

Background: Splenic immunomodulation triggered by ultrasound shows a significant anti-inflammatory effect against various inflammatory diseases, whose mechanism is mainly attributable to the activation of cholinergic anti-inflammatory pathway (CAP). However, the potential role and underlying mechanism of splenic ultrasound stimulation in cancer management have been rarely reported and superficially defined.
Methods: Following optimization of ultrasonic parameters, this study evaluated the anti-tumor efficacy of splenic sonication across multiple tumor models (eg, orthotopic H22 hepatocellular carcinoma (HCC), orthotopic Hepa1-6 HCC, and subcutaneous 4T1 breast cancer), and applied flow cytometry to quantify dynamic alterations in immune cell populations.
