Plumbagin targets the GLUT1/MMP-2 axis to inhibit oral squamous cell carcinoma progression.
Aim: This study aimed to investigate the clinicopathological characteristics and prognostic value of GLUT1 in oral squamous cell carcinoma (OSCC) and the effect of plumbagin (PLB) on inhibiting OSCC invasion and metastasis through the GLUT1/Matrix Metalloproteinase 2 (MMP2) axis pathway.
Materials and methods: One hundred and twenty human OSCC specimens were collected. Immunohistochemistry was performed to analyze the expression, clinicopathological characteristics, and prognostic value of GLUT1 in these specimens. Cal27 and SCC9 cell lines were used to investigate the role of PLB in cell proliferation, migration, invasion, and metastasis in vitro and in vivo.
Results: Immunohistochemistry showed significant associations between GLUT1 expression and MMP2, tumor recurrence, lymphatic metastasis, and TNM stage. In vitro and in vivo experiments demonstrated that PLB inhibited OSCC cell proliferation, migration, and invasion by downregulating GLUT1 and MMP2. WZB117, a GLUT1 inhibitor, also reduced cell colony formation, migration, and invasion. However, univariate and multivariate analyses indicated that GLUT1 expression was not an independent prognostic marker for OSCC overall and disease-free survival.
Conclusions: The findings demonstrated a novel anti-cancer mechanism of plumbagin, inhibiting OSCC invasion and migration by suppressing the GLUT1/MMP2 axis pathway, providing a theoretical basis for the future clinical use of plumbagin in the treatment of OSCC.
期刊介绍：
Cancer Cell International publishes articles on all aspects of cancer cell biology, originating largely from, but not limited to, work using cell culture techniques.
The journal focuses on novel cancer studies reporting data from biological experiments performed on cells grown in vitro, in two- or three-dimensional systems, and/or in vivo (animal experiments). These types of experiments have provided crucial data in many fields, from cell proliferation and transformation, to epithelial-mesenchymal interaction, to apoptosis, and host immune response to tumors.
Cancer Cell International also considers articles that focus on novel technologies or novel pathways in molecular analysis and on epidemiological studies that may affect patient care, as well as articles reporting translational cancer research studies where in vitro discoveries are bridged to the clinic. As such, the journal is interested in laboratory and animal studies reporting on novel biomarkers of tumor progression and response to therapy and on their applicability to human cancers.
