摘要: 摘要: 目的 探究 N-甲基-D-天冬氨酸受体亚型 1(NMDAR1)在结肠癌细胞 HT29 和 SW116 中的表达, 以及 NMDAR1 拮抗剂 MK801 对 HT-29 和 SW116 细胞生长抑制、 凋亡和迁移的影响。方法 采用免疫组织化学法检测 结肠癌细胞 HT-29 和 SW116 细胞表面 NMDAR1 的表达; 应用噻唑蓝(MTT)比色法测定 62.5、 125.0、 250.0、 500.0、 1 000.0、 2 000.0 μmol/L 的 MK801 对于 HT-29 和 SW116 细胞增殖作用的影响; 应用流式细胞术检测 2 000 μmol/L 的 MK801 对 HT29 和 SW116 细胞凋亡的影响; 应用细胞划痕实验检测 50 μmol/L MK801 对于结肠癌细胞 HT-29 和 SW116 迁移能力的影响。结果 结肠癌细胞 HT-29 和 SW116 均表达 NMDAR1, 且主要表达于细胞质中; 各浓度的 MK801 对 HT-29 细胞, 以及浓度为 500.0、 1 000.0、 2 000.0 μmol/L 的 MK801 对 SW116 细胞的生长抑制作用具有时 间效应关系, 24、 48 及 72 h 各 MK801 浓度组对 HT-29 和 SW116 细胞的抑制率随浓度升高整体呈增强趋势, 但抑制 率不呈明显的剂量效应关系; MK801 具有促进 HT-29 和 SW116 细胞凋亡的作用, 且主要表现诱导细胞早期凋亡; MK801 可抑制 HT-29 和 SW116 细胞迁移。结论 NMDAR1 在结肠癌细胞胞质中表达, 且 NMDAR1 拮抗剂 MK801 具有抑制肿瘤细胞生长、 迁移, 促进其早期凋亡的作用, 有望成为新一代抗肿瘤药物。

Abstract: Abstract:Objective To explore the expression of the N- methyl- D- aspartate receptor type 1 (NMDAR1) in the colorectal cancer cells (CRC), and to examine the effects of NMDAR1 antagonists MK801 on proliferation, apoptosis and migration of colorectal cancer cell line HT-29 and SW116 cells. Methods The immunocytochemistry method was used to examine the expressions of NMDAR1 in HT-29 and SW116 cells. MTT assay was used to detect the effects of MK801 (62.5, 125.0, 250.0, 500.0, 1 000.0, 2 000.0 μmol/L) on the proliferation of HT-29 and SW116 cells. The flow cytometry was used to analyze the effect of MK801 (2 000 μmol/L) on cell apoptosis of HT-29 and SW116 cells. Wound healing assay was used to detect the effect of MK801 (50 μmol/L) on the migration of HT- 29 or SW116 cells. Results The NMDAR1 was expressed in both HT- 29 and SW116 cells, and mainly in the cytoplasm. MTT assay showed that there were inhibitory effects of different concentrations of MK 801 (62.5, 125.0, 250.0, 500.0, 1 000.0, 2 000.0 μmol/L) on the proliferation of HT- 29 cells, and inhibitory effects of different concentrations of MK801 (500.0, 1 000.0, 2 000.0 μmol/L) on SW116 cells, in a time- dependent manner. For 24, 48 and 72 h, the inhibitory effects of MK801 on proliferation rates of HT-29 and SW116 cells were increased with the increased concentrations of MK801. MK801 showed an effect to induce cell apoptosis in HT- 29 and SW116 cells, and mainly for early apoptosis. Wound healing assay indicated that MK801 inhibited the cell migration of HT-29 and SW116 cells. Conclusion Results suggest that there is expression of NMDAR1 in colorectal cancer cells. The NMDAR1 antagonist MK801 can inhibit the proliferation, induce cells early apoptosis and inhibit cells migration. It may be a new generation of antitumor drugs.
