BACKGROUND: Nasopharyngeal carcinoma (NPC) is a malignancy induced by the mutation of the transcription factors nuclear factor-kappa B (NF-kB) and peroxisome proliferator-activated receptor-gamma (PPAR-gamma). There was no known of the study about the association and targeted therapy of NF-kB and PPAR-gamma-induced NPC. AIM: This study analyzed and compared the proportion of NF-kB and PPAR-gamma and its association with the clinical characteristic of various NPC patients. METHODS: This was a cross-sectional study and conducted in Adam Malik General Hospital. The samples were paraffin block tissue obtained from 58 NPC patients and underwent immunohistochemistry staining for NF-kB or PPAR-gamma overexpression in March–November 2018. Determination of overexpression was based on the immunoreactive score. The association of NF-kB or PPAR-gamma overexpression with the clinical characteristics of the patients was analyzed using Fisher’s exact test. RESULTS: This study showed a significant increase of NF-kB and PPAR-gamma (p < 0.05). Male was found common than women (3.46:1) with non-keratinizing squamous cell carcinoma as the most common form of NPC (75.9%) and the 41–60 years old is the most common age (56.9%). Overexpression of NF-kB and PPAR-gamma was found mostly in T3-T4 (66.0%; 69.6%), N+ (92.5%; 91.3%), and clinical Stage IV (67.9%; 73.9%), respectively. CONCLUSION: The number of samples overexpressed was proportional to the clinical stage of NPC. This study provides an insight into the relationship of NF-kB and PPAR-gamma to NPC, suggesting their role in the development of malignancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
