Despite the advancements in treatments, the prognosis of patients with advanced or metastatic NPC is still poor. Therefore, it is crucial to identify novel targets and pathways that may serve as potential therapeutic interventions for NPC. The extracellular signal-regulated kinase/mitogen-activated protein kinase (ERK/MAPK) signaling pathway is a crucial regulator of cell growth, proliferation, and survival, which has been linked to various human cancers. However, the exact role of the ERK/MAPK signaling pathway in the proliferation of NPC cells remains unclear.Objective:This study aims to investigate the role of the ERK/MAPK signaling pathway in the proliferation of NPC cells and explore its potential as a therapeutic target for NPC.Methods:1. Cell culture and treatment: NPC cell lines will be cultured and treated with the mitogen-activated protein kinase/extracellular signal-regulated kinase (MEK) inhibitor, U0126, to inhibit the ERK/MAPK pathway activation.2. Cell viability assay: Cell Counting Kit-8 (CCK-8) assay will be used to measure cell viability and proliferation.3. Western blot analysis: The protein expressions of p-ERK and ERK will be detected by Western blotting.4. Statistical analysis: The results will be statistically analyzed using one-way ANOVA followed by Dunnett’s multiple comparison test.精品文档---下载后可任意编辑Expected Results:We expect that the inhibition of the ERK/MAPK pathway by U0126 will reduce the proliferation of NPC cells. Furthermore, we anticipate a significant decrease in the expression of p-ERK in the U0126-treated cells compared to the control group.Conclusion:This study will provide valuable insights into the role of the ERK/MAPK signaling pathway in the proliferation of NPC cells. Our findings may lead to the development of novel therapeutic strategies for NPC by targeting the ERK/MAPK pathway.
