    Wendong Jia#, Ting Zhang#, Ziying Zhang, Lingzhi Wu, Xihao Fu, Zhenxin Wang*, Ni Yin*

    Oncology Research, Vol.34, No.1, 2026, DOI:10.32604/or.2025.068651 - 30 December 2025

    Abstract Objectives: Chromobox 4 (CBX4), a polycomb protein family member linked to tumor pathogenesis via dysregulation, has an incompletely defined role in gastric cancer (GC). The study aimed to investigate the role and mechanism of CBX4 in GC progression and evaluate its potential as a therapeutic target. Methods: CBX4 expression was assessed in GC tissues vs. adjacent non-cancerous tissues and in GC cell lines vs. normal gastric mucosal epithelial cells. Clinicopathological correlations were analyzed. Functional impacts of CBX4 were determined using knockdown and overexpression models in vitro (cell proliferation, migration, invasion) and in vivo (xenograft tumorigenesis in nude… More >

    miR-557 suppresses hepatocellular carcinoma cell proliferation and migration via downregulating CBX4

    XULONG SUN1,#, WENTAO DING2,#, CHAO JIANG3, ZHIAN FANG4,*

    BIOCELL, Vol.48, No.7, pp. 1071-1079, 2024, DOI:10.32604/biocell.2024.050519 - 03 July 2024

    Abstract Introduction: Hepatocellular carcinoma (HCC), a prevalent malignancy, poses significant challenges with high tumor heterogeneity and poor prognosis. MicroRNAs (miRNAs) play a pivotal role in hepatocarcinogenesis. Although abnormalities in microRNA-557 (miR-557) expression have been implicated in various cancer types, its role in HCC remains unclear. Therefore, there is a need to explore the function of microRNA-557 in HCC. Methods: Candidate miRNAs were identified through screening in GSE108724 and GSE20077. Real-time PCR was employed to analyze the expression level of miR-557 in hepatoma cell lines and tissues. Cell viability and migration assays were applied to assess the… More > Graphic Abstract
