Abstract Objective: The tumor microenvironment plays a pivotal role in prostate cancer progression and may differ across metastatic sites. This study aimed to evaluate and compare the primary and metastatic prostate adenocarcinoma tumor microenvironment. Methods: A total of 27 formalin-fixed paraffin-embedded tissue samples derived from 17 patients diagnosed with prostate adenocarcinoma, including the primary tumors, and the corresponding metastatic lymphatic and hematogenous lesions from various anatomical sites. Immunohistochemical labeling was performed using antibodies against Cluster of Differentiation 3 epsilon chain (CD3e), CD8 alpha chain (CD8a), Cluster of Differentiation 68 (CD68), Cluster of Differentiation 163 (CD163), Forkhead… More > Graphic Abstract

Abstract Background: Radiation sensitive 23 homolog B (RAD23B), a DNA repair-related protein, plays a contributory role in the development of multiple malignancies. This study aimed to explore the role of RAD23B in promoting colorectal cancer (CRC) metastasis and to elucidate the underlying molecular mechanisms. Methods: RAD23B was overexpressed in CRC cell lines SW480 and HCT-8, with empty vectors serving as controls. Invasion, cell proliferation, and migration were assessed using CCK-8 and Transwell assays. A xenograft mouse model was used to evaluate metastatic potential in vivo. Immunoprecipitation-mass spectrometry (IP-MS) and transcriptomic analysis by RNA sequencing (RNA-seq) were performed… More >

Abstract Objectives: Ovarian cancer (OC) is a highly heterogeneous disease characterized by high metastatic potential and frequent recurrence. 3β-hydroxysterol Δ24-reductase (DHCR24) is closely associated with the progression of various malignant tumors, but its role in OC remains unexplored. This study is the first to systematically investigate the function of DHCR24 in OC and elucidate its mechanism in promoting OC progression, providing novel theoretical insights for targeted therapy. Methods: The expression of DHCR24 was evaluated in tissues using bioinformatics and clinical data; the impact of DHCR24 on the malignant behavior of OC was assessed through in vivo and in… More >

Abstract Tumor-to-tumor metastasis (TTM) is a rare phenomenon in which a secondary tumor colonizes within a primary tumor of a different histogenesis. It is hypothesized that TTM is encouraged by conditions that promote increased cell growth and division in the primary tumor, such as hypervascularity and expression of oncogenic cytokines. However, the exact causes of TTM likely vary on a case-by-case basis and are dependent on the microenvironment of both the primary and secondary tumors. Herein, we present the first reported example of TTM in which a pulmonary neuroendocrine tumor (NET) metastasizes to a renal oncocytoma. More >

Abstract Background: Non-small cell lung cancer (NSCLC) patients with leptomeningeal metastasis (LM) have a very poor prognosis. Intrathecal pemetrexed (IP) has shown moderate efficacy in treating patients with NSCLC-LM. Myelosuppression is the most common adverse effect following IP administration. Despite this trend, the specific risk factors contributing to IP-related myelosuppression remain unclear. Methods: This study conducted a retrospective analysis of lung adenocarcinoma (LUAD) patients with LM who received IP treatment at the Second Affiliated Hospital of Nanchang University from April 2017 to April 2024. Risk factors for myelosuppression were identified through univariate and multivariate logistic regression… More >

Abstract Objectives: While programmed cell death 1 (PD-1) inhibitors have improved cancer treatment, the function and mechanisms of programmed cell death ligand 1 (PD-L1), particularly when expressed by cancer cells, remain unclear. This study aims to explore the role of PD-L1 within breast cancer cells and identify key targets for future immunotherapy. Methods: RNA-seq was performed on breast cancer cells with silenced PD-L1 to screen for differentially expressed genes, followed by bioinformatics analysis. Clinical specimens from breast cancer patients undergoing primary surgery without preoperative treatment were collected, along with in vitro analysis to validate the potential mechanism. Results:… More >
