Objective

To explore the effect and mechanism of circular RNA RAS p21 protein activator 2 (circRASA2) mediated by nobiletin (NOB) on lipopolysaccharide (LPS)-induced hPDLCs in periodontal ligament cells.

Methods

hPDLCs cells were divided into control group, model group (hPDLCs cells were treated with 10 μg·mL-1 LPS for 24 h), NOB-H group (Based on the model group, 20 μmol·L-1 NOB was given for 24 h), NOB+oe-NC group (hPDLCs cells transfected with oe-NC were treated with 20 μmol·L-1 NOB) and NOB+oe-circRASA2 group (hPDLCs cells transfected with oe-circRASA2 were treated with 20 μmol·L-1 NOB). Quantitative real time polymerase chain reaction was used to detect the mRNA expression levels of circRASA2. The secretion levels of inflammation-related factors were detected by enzyme-linked immunosorbent assay. Western blot analysis of slit homolog 2 (Slit2)/mitogen-activated protein kinase (MAPK) signaling pathway related protein expression levels.

Results

The relative expression levels of circRASA2 in control group, model group and NOB-H group were 1.00±0.15, 2.83±0.50 and 1.36±0.27, respectively. The levels of interleukin-1β in control group, model group, NOB-H group, NOB+oe-NC group and NOB+oe-circRASA2 group were (144.82±24.89), (367.54±65.73), (228.51±40.24), (219.78±36.94) and (324.25±61.57) mg·mL-1, respectively; interleukin-18 levels were (167.50±27.33), (394.68±74.96), (212.47±39.51), (205.93±41.18) and (358.11±66.27) mg·mL-1, respectively; the relative expression levels of Slit2 protein were 1.00±0.18, 2.35±0.41, 1.61±0.29, 1.57±0.27 and 2.14±0.38, respectively; the ratios of phospho-p38 mitogen-activated protein kinase/p38 mitogen-activated protein kinase protein were 1.00±0.16, 2.08±0.37, 1.39±0.25, 1.33±0.21 and 1.92±0.34, respectively. The above indexes in the model group were compared with the control group, the NOB-H group was compared with the model group, and the NOB+oe-circRASA2 group was compared with the NOB+oe-NC group, and the differences were statistically significant (all P<0.05).

Conclusion

NOB alleviates LPS-induced inflammation and inhibits pyroptosis in hPDLCs cells by inhibiting circRASA2 expression, possibly by inhibiting Slit2/MAPK signaling pathway.

目的

探讨川陈皮素(NOB)介导环状RNA RAS p21蛋白激活因子2(circRASA2)对脂多糖(LPS)诱导下牙周膜细胞hPDLCs的作用及其机制。

方法

将hPDLCs细胞分为对照组、模型组(hPDLCs细胞以10 μg·mL-1 LPS处理24 h)、NOB-H组(基于模型组,给予20 μmol·L-1 NOB处理24 h)、NOB+oe-NC组(20 μmol·L-1 NOB处理转染oe-NC的模型组hPDLCs细胞)和NOB+oe-circRASA2组(20 μmol·L-1 NOB处理转染oe-circRASA2的模型组hPDLCs细胞)。用实时定量反转录聚合酶链反应法检测circRASA2的相对表达水平,用酶联免疫吸附试验法检测炎症相关因子的分泌水平,用蛋白质印迹法检测SLIT同源物2(Slit2)/丝裂原活化蛋白激酶(MAPK)信号通路相关蛋白相对表达水平。

结果

对照组、模型组和NOB-H组的circRASA2相对表达水平分别为1.00±0.15、2.83±0.50和1.36±0.27。对照组、模型组、NOB-H组、NOB+oe-NC组和NOB+oe-circRASA2组的白细胞介素-1β水平分别为(144.82±24.89)、(367.54±65.73)、(228.51±40.24)、(219.78±36.94)和(324.25±61.57)mg·mL-1,白细胞介素-18水平分别为(167.50±27.33)、(394.68±74.96)、(212.47±39.51)、(205.93±41.18)和(358.11±66.27)mg·mL-1,Slit2蛋白相对表达水平分别为1.00±0.18、2.35±0.41、1.61±0.29、1.57±0.27和2.14±0.38,磷酸化-p38丝裂原活化蛋白激酶/p38丝裂原活化蛋白激酶蛋白比值分别为1.00±0.16、2.08±0.37、1.39±0.25、1.33±0.21和1.92±0.34。模型组的上述指标与对照组比较,NOB-H组的上述指标与模型组比较,NOB+oe-circRASA2组的上述指标与NOB+oe-NC组比较,在统计学上差异均有统计学意义(均P<0.05)。

结论

NOB通过抑制circRASA2表达,减轻LPS诱导的hPDLCs细胞炎症水平,抑制细胞焦亡,可能是通过抑制Slit2/MAPK信号通路实现的。

目的

探讨川陈皮素(NOB)介导环状RNA RAS p21蛋白激活因子2(circRASA2)对脂多糖(LPS)诱导下牙周膜细胞hPDLCs的作用及其机制。

方法

将hPDLCs细胞分为对照组、模型组(hPDLCs细胞以10 μg·mL-1 LPS处理24 h)、NOB-H组(基于模型组,给予20 μmol·L-1 NOB处理24 h)、NOB+oe-NC组(20 μmol·L-1 NOB处理转染oe-NC的模型组hPDLCs细胞)和NOB+oe-circRASA2组(20 μmol·L-1 NOB处理转染oe-circRASA2的模型组hPDLCs细胞)。用实时定量反转录聚合酶链反应法检测circRASA2的相对表达水平,用酶联免疫吸附试验法检测炎症相关因子的分泌水平,用蛋白质印迹法检测SLIT同源物2(Slit2)/丝裂原活化蛋白激酶(MAPK)信号通路相关蛋白相对表达水平。

结果

对照组、模型组和NOB-H组的circRASA2相对表达水平分别为1.00±0.15、2.83±0.50和1.36±0.27。对照组、模型组、NOB-H组、NOB+oe-NC组和NOB+oe-circRASA2组的白细胞介素-1β水平分别为(144.82±24.89)、(367.54±65.73)、(228.51±40.24)、(219.78±36.94)和(324.25±61.57)mg·mL-1,白细胞介素-18水平分别为(167.50±27.33)、(394.68±74.96)、(212.47±39.51)、(205.93±41.18)和(358.11±66.27)mg·mL-1,Slit2蛋白相对表达水平分别为1.00±0.18、2.35±0.41、1.61±0.29、1.57±0.27和2.14±0.38,磷酸化-p38丝裂原活化蛋白激酶/p38丝裂原活化蛋白激酶蛋白比值分别为1.00±0.16、2.08±0.37、1.39±0.25、1.33±0.21和1.92±0.34。模型组的上述指标与对照组比较,NOB-H组的上述指标与模型组比较,NOB+oe-circRASA2组的上述指标与NOB+oe-NC组比较,在统计学上差异均有统计学意义(均P<0.05)。

结论

NOB通过抑制circRASA2表达,减轻LPS诱导的hPDLCs细胞炎症水平,抑制细胞焦亡,可能是通过抑制Slit2/MAPK信号通路实现的。

Objective

To explore the effect and mechanism of circular RNA RAS p21 protein activator 2 (circRASA2) mediated by nobiletin (NOB) on lipopolysaccharide (LPS)-induced hPDLCs in periodontal ligament cells.

Methods

hPDLCs cells were divided into control group, model group (hPDLCs cells were treated with 10 μg·mL-1 LPS for 24 h), NOB-H group (Based on the model group, 20 μmol·L-1 NOB was given for 24 h), NOB+oe-NC group (hPDLCs cells transfected with oe-NC were treated with 20 μmol·L-1 NOB) and NOB+oe-circRASA2 group (hPDLCs cells transfected with oe-circRASA2 were treated with 20 μmol·L-1 NOB). Quantitative real time polymerase chain reaction was used to detect the mRNA expression levels of circRASA2. The secretion levels of inflammation-related factors were detected by enzyme-linked immunosorbent assay. Western blot analysis of slit homolog 2 (Slit2)/mitogen-activated protein kinase (MAPK) signaling pathway related protein expression levels.

Results

The relative expression levels of circRASA2 in control group, model group and NOB-H group were 1.00±0.15, 2.83±0.50 and 1.36±0.27, respectively. The levels of interleukin-1β in control group, model group, NOB-H group, NOB+oe-NC group and NOB+oe-circRASA2 group were (144.82±24.89), (367.54±65.73), (228.51±40.24), (219.78±36.94) and (324.25±61.57) mg·mL-1, respectively; interleukin-18 levels were (167.50±27.33), (394.68±74.96), (212.47±39.51), (205.93±41.18) and (358.11±66.27) mg·mL-1, respectively; the relative expression levels of Slit2 protein were 1.00±0.18, 2.35±0.41, 1.61±0.29, 1.57±0.27 and 2.14±0.38, respectively; the ratios of phospho-p38 mitogen-activated protein kinase/p38 mitogen-activated protein kinase protein were 1.00±0.16, 2.08±0.37, 1.39±0.25, 1.33±0.21 and 1.92±0.34, respectively. The above indexes in the model group were compared with the control group, the NOB-H group was compared with the model group, and the NOB+oe-circRASA2 group was compared with the NOB+oe-NC group, and the differences were statistically significant (all P<0.05).

Conclusion

NOB alleviates LPS-induced inflammation and inhibits pyroptosis in hPDLCs cells by inhibiting circRASA2 expression, possibly by inhibiting Slit2/MAPK signaling pathway.
