The release of CRH in stress response during menopause inhibited the secretion of GnRH, gonadotropic hormone and estrogen and induced the expression of intracellular HSP. As the growing of month, the expression of HSP70 and HSP70mRNA in uterus went up at the beginning and came down in the end. The result might be caused by the following:The increase of CRH and the decrease of estrogen during early menopause weakened the inhibitory effects on HSP.

本实验观察到随着大鼠月龄的增长子宫HSP70及mRNA的表达呈先增后降的变化，早期热休克蛋白的增加可能与CRH的增加及局部雌激素水平下降对HSP抑制作用的降低有关，但随着组织器官的衰退，其蛋白合成能力下降，因而表现出晚期热休克蛋白及基因表达下调。

A potential approach to this problem is to make use of a natural defense mechanism called " the stress response," which is characterized by a transient down - regulated synthesis of nonvital cellular proteins and increased production of endogenous protective factors known as heat shock proteins that act to allow proper refolding of proteins denatured by the incipient injury.

应激反应的特征是一过性下调细胞非必需蛋白的合成及增加被称为热休克蛋白的内源性保护因子的合成。热休克蛋白作用是促使损伤导致变性的蛋白适当地再折叠。HSP家族中HSP70被认为在细胞保护中发挥重要作用。
