摘要
目的比较小鼠性周期各阶段脊髓腰段芳香化酶和三种雌激素受体的变化。方法应用Western blot方法观察小鼠性周期不同阶段脊髓腰段:动情前期(P期)、动情期(E期)、动情后期(M期)、动情间期(D期)脊髓腰段芳香化酶和雌激素受体α(ERα)、β(ERβ)和GPR30表达量的变化。结果芳香化酶的表达在P期、E期、M期及D期分别为0.62,0.63,0.67,0.74,差异无统计学意义(P=0.075);ERα在P期、E期、M期及D期的表达分别为0.34,0.54,0.39,0.35,差异无统计学意义(P=0.065);ERβ在P期、E期、M期及D期的表达分别为0.6,0.62,0.61,0.70,差异无统计学意义(P=0.654);GPR30在P期、E期、M期及D期的表达分别为0.76,0.75,0.80,0.92,差异无统计学意义(P=0.123)。结论循环系统雌激素水平的生理性波动对脊髓腰段芳香化酶和雌激素受体α、β和GPR30含量无明显影响。
Objective To investigate the expression of aromatase and estrogen receptors α(ERα),β(ERβ), GPR30 in the lumbar spinal cord of mouse. Method By Western blot ,the expression of aromatase and estrogen receptors α,β, GPR30 in the lumbar spinal cord were investigated at different stages of estrus cycle.Results The expressions of aromatase in the lumbar spinal cord during the stage of proestrus ,estrus ,metestrus and diestrus were 0.62, 0.63, 0.67, 0.74;there was no significant difference between them(P=0.075). The estrogen receptor α expressed in the lumbar spinal cord during the stage of the estrus cycle were 0.34, 0.54, 0.39, 0.35.They were no statistically significant difference(P=0.065). The expressions of estrogen receptor βin the lumbar spinal cord during the stage of proestrus ,estrus ,metestrus and diestrus were 0.6, 0.62, 0.61, 0.70 .We found no significant difference between them(P=0.654).Moreover, the estrogen receptor GPR30 expressed in the lumbar spinal cord during the stage of the estrus cycle were 0.76, 0.75, 0.80, 0.92. They were no statistically significant difference(P=0.123).Conclusion The physiological levels and cyclic changes of circulating estrogen do not influence the expression of aromatase and estrogen receptor α,β,GPR30 in the spinal cord of mouse.
