在动物模型中,参与代谢动态平衡的生理系统呈现性别差异。研究人员经常使用雄性啮齿动物,因为它们比雌性啮齿动物更能表现出代谢性疾病。因此,女性并不完全是因为公认的性别差异而被使用,这代表着一个机会,可以了解减少代谢性疾病的新因素在一种性别中比另一种更多。美国国立卫生研究院(NIH)的任务是在临床前研究中将性别视为一个生物变量,这对研究人员和同行评审员提出了新的要求,他们往往缺乏用于性别差异研究的模型系统和实验范式的专业知识。这篇综述讨论了利用动物模型和细胞研究代谢稳态和疾病中性别差异的机制的实验设计和解释。我们还强调了目前在研究工具和态度方面的限制,这些限制可能会推迟基础动物研究中性别差异研究的进展。Mauvais-Jarvis等人。使用动物模型和细胞,讨论研究中的实验设计和解释,以解决代谢稳态和疾病中性别差异的机制。他们强调了目前在研究工具和态度方面的局限性,这些限制可能会推迟基础动物研究中性别差异研究的进展。
In animal models, the physiological systems involved in metabolic homeostasis exhibit a sex difference. Investigators often use male rodents because they show metabolic disease better than females. Thus, females are not used precisely because of an acknowledged sex difference that represents an opportunity to understand novel factors reducing metabolic disease more in one sex than the other. The National Institutes of Health (NIH) mandate to consider sex as a biological variable in preclinical research places new demands on investigators and peer reviewers who often lack expertise in model systems and experimental paradigms used in the study of sex differences. This review discusses experimental design and interpretation in studies addressing the mechanisms of sex differences in metabolic homeostasis and disease, using animal models and cells. We also highlight current limitations in research tools and attitudes that threaten to delay progress in studies of sex differences in basic animal research. Mauvais-Jarvis et al. discuss experimental design and interpretation in studies addressing the mechanisms of sex differences in metabolic homeostasis and disease, using animal models and cells.
