项目摘要

Chromaffin cells were found to contain glucocorticoid receptor-immunoreactivity in their nucleus. When dexamethasone was added into the culture medium, the extension of the processes, intensity of immunoreactivity of MAP-2 were significantly diminished. These results indicated that the differentiation of chromaffin cells to neurons is determined, at least in part, by humoral factor of glucocorticoid through its receptor. The addition of antisense oligos for glucocorticoid receptor cleary caused the significant extension of processes of chromaffin cells, indicating that the protein synthesis of steroid receptor was blocked by the antisense inhibitory action to its mRNA.In the sexually dimorphic area of the hypothalamus, immunocytochemical studies show that estrogen induces a significant changes of numbers of immunoreactive never fibers containing neurotensin, calcitonin-gene related peptide (CGRP), Met-enkephalin, cholecystokinin-8 (CCK-8) and dopamine, indicating that axonal sprouting … More of neurons containing these chemical messengers occur in response to estrogen. The relationship between estrogen-receptor and gene expression of these biochemical messengers in concomitant with the process formation or elongation has been discussed, particularly in the context of male and female differences. Estrogen-receptor was found to localize in the cell nucleus by immunocytochemistry in conjunction with the use of estrogen-receptor antibody. Colchicine treatment blocked immunpositive reaction in the cell nucleus, suggesting that estrogen-receptor protein was synthesized in the cytoplasm followed by the transport to the nucleus through nuclear pore in association with microtubules. Monolayr cultures from male and female rat hypothalami were developed and the differences of neurite extension was investigated. In this point, it should be noted that developmental and estrogen-induced changes in mRNAs coding specific proteins for the cytoskeleton, including tubulin-like molecules, have been indentified in the hypothalamic preoptic area.

嗜铬细胞的细胞核中含有糖皮质激素受体的免疫反应。地塞米松可明显抑制MAP-2的免疫反应性。这些结果表明,嗜铬细胞向神经元的分化至少部分是由糖皮质激素的体液因子通过其受体决定的。糖皮质激素受体反义寡核苷酸的加入明显引起嗜铬细胞突起的明显延长,表明类固醇受体的蛋白合成被其mRNA的反义抑制作用所阻断。免疫细胞化学研究表明,在下丘脑的性二形区,雌激素引起含有神经降压素的免疫反应神经纤维的数量的显著变化,降钙素基因相关肽(CGRP)、甲硫氨酸脑啡肽(Met-enkephalin)、胆囊收缩素-8(CCK-8)和多巴胺,表明轴突出芽 ...更多信息 含有这些化学信使的神经元对雌激素的反应。雌激素受体和这些生化信使的基因表达与过程形成或延长之间的关系已被讨论,特别是在男性和女性差异的背景下。用免疫细胞化学结合雌激素受体抗体的方法,发现雌激素受体定位于细胞核。秋水仙素处理阻断了细胞核中的免疫阳性反应,表明雌激素受体蛋白在细胞质中合成,然后通过与微管相关的核孔运输到细胞核中。采用雄性和雌性大鼠下丘脑进行单层培养,观察神经突延伸的差异。在这一点上,应该注意的是,发育和雌激素诱导的mRNA编码的细胞骨架,包括微管蛋白样分子的特异性蛋白质的变化,已被确定在下丘脑视前区。少
