 Abstract
- Background
C-C motif chemokine ligand 3 (CCL3) is a crucial chemokine that plays a fundamental role in the immune microenvironment and is closely linked to the development of various cancers. Despite its importance, there is limited research regarding the expression and function of CCL3 in nasopharyngeal carcinoma (NPC). Therefore, this study seeks to examine the expression of CCL3 and assess its clinical significance in NPC using bioinformatics analysis and experiments. Methods: The bioinformatics approach was employed to assess the expression and function of CCL3 in NPC. Subsequently, protein expression of CCL3 was detected in an NPC cohort using immunohistochemistry based on a tissue microarray. The relationship between CCL3 expression and clinical features was then investigated. Results: A total of 20 CCL3-related genes and 14 possible target genes were identified through bioinformatics analysis, many of which play crucial roles in pathways such as chemokine signaling pathway and transcriptional misregulation in cancer signaling pathways. CCL3 was found to be associated with drug resistance and various immune cell infiltrations. In NPC, CCL3 expression was significantly higher than normal controls, and high expression of CCL3 correlated with cervical lymph node metastasis, tumor recurrence, advanced clinical stage, and poor prognosis. Conclusions: CCL3 may be a key gene in the initiation and progression of NPC. It has the potential to serve as both a diagnostic biomarker and a therapeutic target for NPC.
