摘要: 目的 研究在抑郁症(MDD)患者队列外周血及慢性不可预知温和型应激(CUMS)小鼠模型大脑组织中前列腺素E1(PGE1)浓度及其代谢通路上的关键基因(PLA2、PTGS1、PTGS2和PTGES)表达量的改变,以明确PGE1的改变与MDD疾病间的关系 方法 用高效液相色谱(HPLC)检测受试者外周血浆和CUMS小鼠脑组织中PGE1和PGE2的浓度;用RT-qPCR检测PLA2、PTGS1、PTGS2和PTGES的mRNA表达水平。 结果 在MDD患者中,血浆PGE1浓度和PTGS1的表达水平均显著上升(p<0.05)。这一结果在CUMS小鼠外周血和大脑杏仁核组织中得到了有效验证。 结论 PGE1在MDD中的上升,可能与前列腺素合成通路的功能亢进有关。

Abstract: Objective To illuminate the relationship between prostaglandin E1 (PGE1) and major depressive disorder (MDD) with detection of the PGE1 concentration levels and the expressional levels of key genes in PGs synthetic pathway (PLA2, PTGS1, PTGS2, PTGES) in both blood samples of patients with MDD and the brain tissue of chronic unpredictable mild stress (CUMS) mice. Methods High performance liquid chromatography (HPLC) was used to detect the levels of PGE1 in plasma and brain tissues, and quantitative real-time PCR (RT-qPCR) was used to detect the mRNA levels of PLA2, PTGS1, PTGS2, PTGES. Results The plasma PGE1 concentration and the mRNA level of PTGS1 gene were significant higher in MDD patients, and this result was well validated in the blood and amygdala of CUMS mice. Conclusion The rise of PGE1 in MDD may be related to the hyperfunction of the prostaglandin synthesis pathway.
