Current screening methods for esophageal squamous cell carcinoma (ESCC) face challenges such as low patient compliance and high costs. This study aimed to develop a model based on oral microbiome data for identifying ESCC. By analyzing 249 oral flora samples, we identified microbial markers associated with ESCC and constructed random forest classifiers that distinguished patients with ESCC from controls, achieving an area under the ROC curve (AUC) of 0.

A self-assembled fluorescent nanoprobe recognized by FA1 site for specifically selecting HSA: Its applications in hemin detection, cell imaging and fluorescent tracing drug delivery.

As naturally essential biomacromolecule, HSA has become diagnostic indicators for various diseases and universal carriers for anticancer drug delivery, therefore, fluorescence detection and labeling for HSA possess significant application value in the biomedical field. In this paper, hydrazide Schiff base fluorescent probe NDQC was designed and synthesized, which self-assembled into nanoparticles in aqueous solution system and demonstrated excellent selectivity and sensitivity towards HSA. Through displacement assay and molecular docking simulation, the binding of NDQC with HSA in FA1 site was demonstrated, thereby no obvious fluorescence signal presented for homologous protein BSA due to their structural differences in binding site.

Habitat radiomics based on CT images to predict survival and immune status in hepatocellular carcinoma, a multi-cohort validation study.

Background And Objective: Though several clinicopathological features are identified as prognostic indicators, potentially prognostic radiomic models are expected to preoperatively and noninvasively predict survival for HCC. Traditional radiomic models are lacking in a consideration for intratumoral regional heterogeneity. The study aimed to establish and validate the predictive power of multiple habitat radiomic models in predicting prognosis of hepatocellular carcinoma (HCC).

Advancing precision medicine: the transformative role of artificial intelligence in immunogenomics, radiomics, and pathomics for biomarker discovery and immunotherapy optimization.

Artificial intelligence (AI) is significantly advancing precision medicine, particularly in the fields of immunogenomics, radiomics, and pathomics. In immunogenomics, AI can process vast amounts of genomic and multi-omic data to identify biomarkers associated with immunotherapy responses and disease prognosis, thus providing strong support for personalized treatments. In radiomics, AI can analyze high-dimensional features from computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography/computed tomography (PET/CT) images to discover imaging biomarkers associated with tumor heterogeneity, treatment response, and disease progression, thereby enabling non-invasive, real-time assessments for personalized therapy.

Elucidating the expression and role of cGAS in pan-cancer using integrated bioinformatics and experimental approaches.

cGAS plays an important role in regulating both tumor immune responses and DNA damage repair. Nevertheless, there was little research that comprehensively analyzed the correlation between cGAS and the tumor microenvironment, immune cell infiltration, and DNA damage repair in different cancers. In this study, The Cancer Genome Atlas (TCGA) and Cancer Cell Line Encyclopedia (CCLE) data were used to analyze the mRNA expression and genomic alterations of cGAS in pan-cancer.

Predictive markers of rapid disease progression and chemotherapy resistance in triple-negative breast cancer patients following postoperative adjuvant therapy.

Triple-negative breast cancer (TNBC) is a diverse category with a subset that displays particularly aggressive characteristics, referred to in this study as "rapid relapse" TNBC (rrTNBC). This term is defined as the occurrence of distant metastasis or death within 24 months post-diagnosis. The paper mainly studies the clinicopathologic traits of TNBC patients experiencing rapid disease progression and chemotherapy resistance and identify predictive markers for this outcome.

Purpose: To investigate clinicopathologic characteristics and prognosis in secretory breast carcinoma (SBC) and to determine chemotherapy benefits stratified by different subgroups.

Methods: SBCs and triple-negative invasive ductal carcinoma patients (TN-IDCs) were enrolled from three cancer centers between January 2011 and December 2020. SBCs were further divided into two subgroups: those with triple negativity (TN-SBCs) and those without (non-TN-SBCs).

The interaction of isoquinoline alkaloid crebanine with immunoglobulin G and cytotoxic effects toward MCF-7 breast cancer cell line.

In this study, the interaction of crebanine, an isoquinoline alkaloid, with immunoglobulin G (IgG) was evaluated. Subsequently, the anticancer effects of crebanine in MCF-7 breast cancer cells were assessed. The results demonstrate that static quenching plays a key role in the fluorescence quenching of the IgG by crebanine, and some embedded hydrophobic patches of the IgG are exposed upon interaction with crebanine, while the characteristic β-sheet conformation of the IgG was almost preserved.

Successful conversion surgery after comprehensive therapy in a patient with MSI-H but pMMR metastatic gastric mixed adenoneuroendocrine carcinoma: a case report and literature review.

Gastric mixed adenoneuroendocrine carcinoma (MANEC) is a rare and highly aggressive malignancy characterized by both exocrine and neuroendocrine components. Treatment options for metastatic cases are limited, with typical therapeutic approaches involving a combination of chemotherapy and immunotherapy. A 68-year-old male with metastatic gastric MANEC was treated with targeted therapy, immunotherapy, and chemotherapy, including S-1, apatinib, cadonilimab, and paclitaxel.

Expert consensus on sequential surgery following conversion therapy based on combination of immune checkpoint inhibitors and antiangiogenic targeted drugs for advanced hepatocellular carcinoma (2024 edition).

Up to half of hepatocellular carcinoma (HCC) cases are diagnosed at an advanced stage, for which effective treatment options are lacking, resulting in a poor prognosis. Over the past few years, the combination of immune checkpoint inhibitors and anti-angiogenic targeted therapy has proven highly efficacious in treating advanced HCC, significantly extending patients' survival and providing a potential for sequential curative surgery. After sequential curative hepatectomy or liver transplantation following conversion therapy, patients can receive long-term survival benefits.

An effective drug-free hydrogel for accelerating the whole healing process of bacteria-infected wounds.

Wound healing is a dynamic and complex process involving hemostasis, inflammation, fibroblast proliferation, and tissue remodeling. This process is highly susceptible to bacterial infection, which often leads to impaired and delayed wound repair. While antibiotic therapy remains the primary clinical approach for treating bacteria-infected wounds, its widespread use poses a significant risk of developing bacterial resistance.

Tumor cells induce neural DKK1 expression to promote MDSC infiltration and subsequent T cell suppression.

Nerves are often overlooked as key components of the tumor microenvironment. However, the molecular mechanisms underlying the reciprocal interactions between tumors and nerves remain largely unknown. In this study, we analyzed data from The Cancer Genome Atlas (TCGA) and identified a significant association between DKK1 expression and poor prognosis, as well as a correlation between DKK1 expression and myeloid-derived suppressor cell (MDSC) infiltration in head and neck squamous cell carcinoma (HNSCC) and pancreatic ductal adenocarcinoma (PDAC), two cancer types characterized by pronounced tumor-nerve interactions.

The Nuclear Condensates of ESE3/EHF Induce Cellular Senescence without the Associated Inflammatory Secretory Phenotype in Pancreatic Ductal Adenocarcinoma.

Senescent cells are in a stable state of cell cycle arrest, leading to a natural barrier to tumorigenesis. Senescent cells secrete a pool of molecules, including cytokines, chemokines, proteases, and growth factors, termed the senescence-associated secretory phenotype (SASP), paradoxically contributing to pro-tumorigenic processes. However, the mechanism for regulating senescence and SASP in tumor cells remains unclear.
