ABSTRACT
【Objective】 To study the expressions of BMAL1 and CerbB-2 genes in nasopharyngeal carcinoma (NPC) and their related mechanisms. 【Methods】 Plasmid transfection, MTT, RT-PCR and Western blotting were used to detect the proliferation of NPC cells, the expressions of BMAL1 and CerbB-2 genes and proteins, and the expression of NF-κB signaling pathway. 【Results】 The MTT results showed that BMAL1 and CerbB-2 could affect the proliferation of NPC cells. RT-PCR results showed that BMAL1 gene was significantly down-regulated in NPC (CK: 2.24±0.22, NPC: 0.63±0.11, P<0.01), while CerbB-2 gene expression was significantly up-regulated (CK: 0.89±0.13, NPC: 2.65±0.25, P<0.01). The p50 and p65 genes in the NF-κB signaling pathway were up-regulated in NPC cells (p50, CK: 0.48±0.12, NPC: 1.45±0.25; p65, CK: 0.52±0.12, NPC: 2.33±0.35, P<0.01). The results of Western blotting were consistent with gene expression, which further confirmed the reliability of the results. 【Conclusion】 This study reveals that BMAL1 and CerbB-2 regulate the invasion and metastasis of NPC cells through the inflammatory pathway NF-κB, providing further theoretical support for the treatment and prevention of NPC.
