以前,我们已经发表了氧化应激的药理学诱导导致大鼠的焦虑样行为,也与这些动物的高血压有关。在这里,我们报告了通过药物诱导的亚慢性氧化应激诱导导致i)谷胱甘肽酶(GLO)-1和谷胱甘肽还原酶(GSR)-1表达的减少; ii)钙蛋白酶介导的脑源性神经营养因子(BDNF)水平的减少; iii)NFκB介导的促炎因子白细胞介素(IL)-6和肿瘤坏死因子(TNF)-α的上调以及血管紧张素(AT)升高。1受体水平在海马体,杏仁核和蓝斑区域的大脑。急性氧化应激具有相反的作用。我们推测,GLO 1、GSR 1、BDNF、NFκB B和AT-1受体的调节可能参与了大鼠的焦虑样行为和高血压。
Previously, we have published that pharmacological induction of oxidative stress causes anxiety-like behavior in rats and also is associated with hypertension in these animals. Here, we report that sub-chronic induction of oxidative stress via pharmacological induction leads to i) reduction in glyoxalase (GLO)-1 and glutathione reductase (GSR)-1 expression; ii) calpain mediated reduction of brain derived neurotrophic factor (BDNF) levels; iii) NFκB mediated upregulation of proinflammatory factors interleukin (IL)-6 and tumor necrosis factor (TNF)-α and elevated angiotensin (AT)-1 receptor levels in hippocampus, amygdala and locus coeruleus regions of the brain. Acute oxidative stress has opposite effects. We speculate that regulation of GLO1, GSR1, BDNF, NFκB and AT-1 receptor may contribute to anxiety-like behavior and hypertension in rats.
