Abstract

Background

The trace element lithium (Li) is known for its therapeutic mood-stabilizing application in humans, but also for its various bioactivities, which have been uncovered in model organisms. According to the literature, Li may interfere with the homeostasis of other minerals in mammals, namely sodium, calcium and magnesium. In addition, Li was found to influence the composition and diversity of the intestinal microbiota in vertebrates, an observation that may be related to the many bioactivities of Li.

Methods

Based on these previous findings, we employed the model organism Drosophila melanogaster to decipher whether Li exhibits similar bioactivities in invertebrates. First, we examined the influence of increasing dietary Li supply (0 −100 mM LiCl) on the status of Li and ten other minerals via Inductively coupled plasma - mass spectrometry (ICP-MS) in heads and remaining body parts of the three wildtype strains w1118, Oregon-R-C and Canton-S. In addition, we investigated the potential impact of Li feeding (0, 0.1, 1 mM LiCl) on the total bacterial load, α- and β-diversity via real-time quantitative polymerase chain reaction (RT q-PCR) and 16S rDNA sequencing in the intestines of female w1118.

Results

Our observations revealed that Li accumulates linearly in both sexes and all body parts of the three Drosophila strains as the dietary Li supply increases. While the status of most elements remained unchanged, the sodium levels of the fly also correlated positively with the Li content of the diet. The intestinal microbiota, however, remained largely unaffected by Li feeding in terms of both, bacterial load and diversity.

Conclusion

These findings support the hypothesis that elevating the Li supply affects sodium homeostasis in Drosophila, a finding coherent with observations in mammals. Furthermore, our data opposes a possible involvement of the bacterial intestinal colonization in the bioactivity of Li in Drosophila.

锂会影响钠平衡,但不会影响肠道微生物群--黑腹果蝇研究
背景:微量元素锂(Li)因其对人类稳定情绪的治疗作用而闻名,同时也因其在模式生物体中发现的各种生物活性而闻名。根据文献记载,锂可能会干扰哺乳动物体内其他矿物质(即钠、钙和镁)的平衡。此外,研究还发现锂会影响脊椎动物肠道微生物群的组成和多样性,这可能与锂的多种生物活性有关:方法:基于这些先前的发现,我们利用黑腹果蝇这一模式生物来解读 Li 是否在无脊椎动物中具有类似的生物活性。首先,我们通过电感耦合等离子体质谱法(ICP-MS)检测了w1118、俄勒冈-R-C和Canton-S三个野生型品系的头部和其余身体部位中锂离子和其他十种矿物质的状况。此外,我们还通过实时定量聚合酶链式反应(RT q-PCR)和 16S rDNA 测序研究了喂食锂(0、0.1、1 mM 氯化锂)对雌性 w1118 肠道中细菌总数、α- 和 β-多样性的潜在影响:我们的观察结果表明,随着膳食中锂离子供应量的增加,锂离子在三种果蝇品系的雌雄和所有身体部位都呈线性累积。虽然大多数元素的状态保持不变,但果蝇体内的钠含量也与膳食中的锂含量呈正相关。然而,肠道微生物群在细菌负荷和多样性方面基本不受锂饲喂的影响:这些发现支持了提高锂供应量会影响果蝇体内钠稳态的假设,这一发现与在哺乳动物体内的观察结果一致。此外,我们的数据反对细菌肠道定植可能参与果蝇体内 Li 的生物活性。

期刊介绍: The journal provides the reader with a thorough description of theoretical and applied aspects of trace elements in medicine and biology and is devoted to the advancement of scientific knowledge about trace elements and trace element species. Trace elements play essential roles in the maintenance of physiological processes. During the last decades there has been a great deal of scientific investigation about the function and binding of trace elements. The Journal of Trace Elements in Medicine and Biology focuses on the description and dissemination of scientific results concerning the role of trace elements with respect to their mode of action in health and disease and nutritional importance. Progress in the knowledge of the biological role of trace elements depends, however, on advances in trace elements chemistry. Thus the Journal of Trace Elements in Medicine and Biology will include only those papers that base their results on proven analytical methods. Also, we only publish those articles in which the quality assurance regarding the execution of experiments and achievement of results is guaranteed.
