Abstract

Estrogens are among important contributing factors to many sex differences in neuroendocrine regulation of energy homeostasis induced by stress. Research in this field is warranted since chronic stress-related psychiatric and metabolic disturbances continue to be top health concerns, and sex differences are witnessed in these aspects. For example, chronic stress disrupts energy homeostasis, leading to negative consequences in the regulation of emotion and metabolism. Females are known to be more vulnerable to the psychological consequences of stress, such as depression and anxiety, whereas males are more vulnerable to the metabolic consequences of stress. Sex differences that exist in the susceptibility to various stress-induced disorders have led researchers to hypothesize that gonadal hormones are regulatory factors that should be considered in stress studies. Further, estrogens are heavily recognized for their protective effects on metabolic dysregulation, such as anti-obesogenic and glucose-sensing effects. Perturbations to energy homeostasis using laboratory rodents, such as physiological stress or over-/under- feeding dietary regimen prevalent in today's society, offer hints to the underlying mechanisms of estrogenic actions. Metabolic effects of estrogens primarily work through estrogen receptor α (ERα), which is differentially expressed between the sexes in hypothalamic nuclei regulating energy metabolism and in extrahypothalamic limbic regions that are not typically associated with energy homeostasis. In this review, we discuss estrogenic actions implicated in stress-induced sex-distinct metabolic disorders.

摘要

雌激素是应激引起的神经内分泌调节能量平衡的许多性别差异的重要影响因素之一。由于与慢性应激相关的精神和代谢紊乱仍然是主要的健康关注点,并且在这些方面观察到了性别差异,因此该领域的研究是合理的。例如,慢性应激会破坏能量平衡,导致情绪和代谢调节的负面后果。众所周知,女性更容易受到应激的心理后果的影响,如抑郁和焦虑,而男性更容易受到应激的代谢后果的影响。存在于各种应激诱导的疾病易感性中的性别差异促使研究人员假设,性腺激素是应在应激研究中考虑的调节因素。此外,雌激素因其对代谢失调的保护作用而受到广泛关注,如抗肥胖和葡萄糖感应作用。使用实验室啮齿动物(如生理应激或当今社会流行的过度/不足喂养饮食方案)扰乱能量平衡,为雌激素作用的潜在机制提供了线索。雌激素的代谢作用主要通过雌激素受体 α (ERα) 发挥作用,ERα 在调节能量代谢的下丘脑核和与能量平衡无关的下丘脑外边缘区域在性别之间存在差异表达。在这篇综述中,我们讨论了应激引起的性别特异性代谢紊乱中涉及的雌激素作用。
