[Abstract]  Exercise induces beneficial systemic adaptations that reduce the incidence of age-related diseases. However, the molecular pathways that elicit these adaptations are not well understood. Understanding the molecular mechanisms that underlie the exercise response can lead to widely beneficial therapies. Large populations, relatively short lifespan, and easily modifiable genetics make Drosophila a well-suited model system for complex, longitudinal studies. We have developed an enforced climbing apparatus for Drosophila, known as the Power Tower, for the study of systemic exercise adaptations. The Power Tower takes advantage of the fly’s natural instinct for negative geotaxis, an innate behavior to run upwards after being tapped to the bottom of their vial. Flies will ... [摘要]  运动诱导有益的系统适应,减少与年龄有关的疾病的发生率。然而,引起这些适应的分子途径还不是很清楚。了解作为运动反应基础的分子机制可以产生广泛有益的疗法。大群体,相对较短的寿命和易于修改的遗传学使得 Drosophila 成为复杂纵向研究的一个非常适合的模型系统。我们开发了一种用于 Drosophila 的强制攀爬装置,称为Power Tower,用于研究系统性运动适应性。 Power Tower利用苍蝇的天然本能来消极地质,这是一种天生的行为,在被轻敲到他们的小瓶底部之后向上运行。苍蝇将持续运行至耗尽点或直至机器关闭,以先到者为准。运动3周后,雄性 Drosophila 适应训练,具有许多类似于哺乳动物模型和人类所见的保守,易于量化的生理改善。在这里,我们描述了一个有用的耐力训练协议和一套有效量化训练效果的训练后评估。
【背景】耐力运动可以降低几乎所有与年龄相关的疾病(Ciolac,2013)。耐力训练对心血管功能,能量代谢和活动有很强的作用,从苍蝇到人类都是高度保守的(Piazza et al。,2009; Booth et al。,2015 ; Wilson et al。,2015)。更好地理解运动的遗传介质可能会导致治疗方法,这些治疗方法可以使因疾病或受伤而无法运动的个体受益。 Drosophila ...
