The aim of this study was to target enzymes specifically to cells in the murine spleen. Monomeric and polymeric conjugates of the enzymes horseradish peroxidase or alkaline phosphatase and monoclonal antibodies against cell surface determinants were prepared. Highly specific in vivo targeting of enzymes to macrophages was obtained only when monomeric MAb-enzyme conjugates were used.

Development of a novel molecular probe for visualizing mesothelin on the tumor via positron emission tomography.

Eur J Nucl Med Mol Imaging

January 2025

Institute of Radiation Medicine, Fudan University, Xietu Road 2094, Shanghai, 200032, China.

Objectives: Mesothelin (MSLN) is an antigen that is overexpressed in various cancers, and its interaction with tumor-associated cancer antigen 125 plays a multifaceted role in tumor metastasis. The serum MSLN expression level can be detected using enzyme-linked immunosorbent assay; however, non-invasive visualization of its expression at the tumor site is currently lacking. Therefore, the aim of this study was to develop a molecular probe for imaging MSLN expression through positron emission tomography (PET).

SHP2 promotes the epithelial-mesenchymal transition in triple negative breast cancer cells by regulating β-catenin.

J Cancer Res Clin Oncol

January 2025

Key Laboratory of Laboratory Medicine, Ministry of Education of China, School of Laboratory Medicine and Life Sciences, Wenzhou Medical University, Wenzhou, 325035, Zhejiang, China.

Purpose: Growing evidence suggests that the tyrosine phosphatase SHP2 is pivotal for tumor progression. Triple-negative breast cancer (TNBC) is the most lethal subtype of breast cancer, characterized by its high recurrence rate, aggressive metastasis, and resistance to chemotherapy. Understanding the mechanisms of tumorigenesis and the underlying molecular pathways in TNBC could aid in identifying new therapeutic targets.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) is associated with poor prognosis. The roles of the transcription factor special AT-rich binding protein-2 (SATB2) and β-catenin in PDAC have been a subject of controversy. We aimed to assess the diagnostic and prognostic impact of SATB2 and β-catenin in PDAC.

Purpose: Reports of gene therapy-associated retinal atrophies and inflammation have highlighted the importance of preclinical safety assessments of adeno-associated virus (AAV) vector systems. We evaluated in nonhuman primates (NHPs) the ocular safety and toxicology of a novel AAV gene therapy targeting retinitis pigmentosa caused by mutations in PDE6A, which has since been used in a phase I/II clinical trial (NCT04611503).

Methods: A total of 34 healthy cynomolgus animals (Macaca fascicularis) were treated with subretinal injections of rAAV.

Xuefu Zhuyu Decoction (XZD) is widely used in the treatment of cardiovascular diseases. The purpose of this study was to explore the pharmacological effects and molecular mechanisms of XZD in improving hyperlipidemia and to provide a theoretical framework for clinical application. In this study, the signaling pathways regulated by XZD in improving hyperlipidemia were predicted by network pharmacology.
