Abstract Background: Prostate cancer (PCa) responds poorly to immunotherapy. We investigated the myeloid checkpoint TIM3 (HAVCR2) to define its lineage localization and regulatory logic in the PCa microenvironment. Methods: We integrated stage-resolved public single-cell RNA-seq datasets spanning primary PCa, metastatic hormone-sensitive PCa, and castration-resistant PCa. Myeloid compartments were analyzed via differential expression, regulon inference, and ligand–receptor modeling. Clinical relevance was evaluated in the Cancer Genome Atlas prostate adenocarcinoma (TCGA-PRAD) cohort and independent cohorts using a myeloid TIM3 signature. Mechanistic validation was achieved through PR domain zinc finger protein 1 (PRDM1) chromatin immunoprecipitation followed by Chromatin Immunoprecipitation (ChIP)–qPCR… More >

Abstract Backgrounds: Early B-cell factor 1 (EBF1), originally identified as a critical transcription factor modulating the development and differentiation of B lymphocytes, has recently attracted significant interest owing to its diverse functional characteristics and regulatory mechanisms in solid tumors. Although current evidence suggests a potential connection between EBF1 and oncogenic developments, its exact role in the progression of prostate cancer (PCa) is unclear. This study sought to investigate its biological roles and regulatory mechanisms in human PCa. Methods: Bioinformatic analyses were performed utilizing Tumor Immune Estimation Resource (TIMER) 2.0, Gene Expression Profiling Interactive Analysis (GEPIA), and Gene… More >

Abstract Background: Bisphenol A (BPA) is a widely used industrial chemical and endocrine-disrupting compound, and accumulating evidence suggests that it may contribute to prostate cancer progression; however, the underlying molecular mechanisms remain incompletely elucidated. This study aimed to elucidate the molecular targets and signaling pathways underlying BPA-induced prostate cancer progression. Methods: In this study, an integrated strategy combining network toxicology, molecular docking, and molecular dynamics simulations was employed to identify potential BPA-related targets and signaling pathways involved in prostate cancer. Candidate targets were retrieved from public databases, followed by protein-protein interaction network analysis to screen key… More >

Abstract Objectives: Patients with a multi-parameter magnetic resonance imaging (mpMRI) prostate imaging report and data system (PI-RADS) score ≤ 3, but with clinically significant prostate cancer (CSPCa) detected by biopsy, are termed MRI-Invisible prostate cancer (MRI(-)PCa). This study aims to explore risk factors for MRI(-)PCa and identify immunohistochemical indicators with predictive significance. Methods: A retrospective analysis was conducted on 376 patients with PI-RADS score ≤ 3 who underwent 24-needle systematic prostate biopsy at Beijing Friendship Hospital, Capital Medical University (January 2015 to October 2025). Clinical data, imaging data, and Angiogenic factor with G and FHA domain… More >

Abstract Background: Observational studies have suggested potential associations between myocardial infarction (MI) and cancer risk, but the causal nature of these relationships remains unclear due to confounding factors and reverse causation. We aimed to investigate the bidirectional causal relationships between MI and urinary system cancers using genetic instruments. Methods: We conducted a two-sample Mendelian randomization (MR) analysis using summary statistics from large-scale genome-wide association studies. Genetic variants associated with MI were used as instrumental variables (n = 19 SNPs for prostate cancer [PCa] and malignant neoplasm of kidney [MRN], n = 6 SNPs for bladder cancer,… More >

Abstract Background: Regional differences in the incidence of prostate cancer (PCa) and prostatitis may be due to different food intake. But which foods affect PCa and prostatitis development or progression remains controversial. This study aims to explore the causal relationship between PCa and prostatitis and 30 different foods using two-sample Mendelian randomization (MR) and multivariable MR (MVMR) analysis. Methods: Data on 30 different foods were screened from the UK Biobank. PCa data came from a large meta-analysis of 140,254 individuals; prostatitis was obtained from the FinnGen consortium. The inverse variance weighted method was the main analysis… More >

Abstract Objectives: Prostate cancer (PCa) is a highly prevalent male malignancy with limited efficacy in advanced stages. Dysregulated modulation of necroptosis was reported to be tightly correlated with PCa initiation and progression. Herein, we aimed to identify necroptosis-associated long non-coding RNAs (lncRNAs) and delineate their functional roles in PCa through an integrated approach combining bioinformatic analyses and in vitro experimental validation. Methods: RNA sequencing data and corresponding clinical information of PCa were downloaded from The Cancer Genome Atlas (TCGA). Differentially expressed necroptosis-related genes (NRGs) and lncRNAs were screened, and necroptosis activity was assessed by single-sample gene set… More >

Abstract Objective: The progression of prostate cancer cells to metastasis is supported by their tumor microenvironment. Within this microenvironment, infiltrating immune cells, such as B cells, can be either anti-tumorigenic or pro-tumorigenic. Our preliminary data showed that a higher density of the infiltrating B cells was found near prostate cancer cells in human cancer tissues, as compared to the benign prostate tissue regions, thus suggesting that infiltrating B cells would promote the progression of prostate cancer cells. In this study, we aim to investigate the role of infiltrating B cells in enhancing the migratory ability of… More >

Abstract Objective: Prostate cancer is the second most common fatal cancer in men. Identifying new biological therapeutic targets is crucial to effectively improve the prognosis of prostate cancer patients. Ovarian tumor family deubiquitinase 4 (OTUD4) is a member of the ovarian tumor-associated protease domain (OTUDs) family. Although previous studies have shown that the expression and function of OTUD4 vary across different tumors, its role in prostate cancer remains unknown. The aim of this study is to explore new therapeutic targets and diagnostic markers for prostate cancer and investigate their mechanisms of action. Methods: Cell culture, Cell… More >
