Aluminum, the third most abundant metal present in the earth's crust, is present almost in all daily commodities we use, and exposure to it is unavoidable. The interference of aluminum with various biochemical reactions in the body leads to detrimental health effects, out of which aluminum-induced neurodegeneration is widely studied. However, the effect of aluminum in causing dyslipidemia cannot be neglected. Dyslipidemia is a global health problem, which commences to the cosmic of non-communicable diseases. The interference of aluminum with various iron-dependent enzymatic activities in the tri-carboxylic acid cycle and electron transport chain results in decreased production of mitochondrial adenosine tri-phosphate. This ultimately contributes to oxidative stress and iron-mediated lipid peroxidation. This mitochondrial dysfunction along with modulation of α-ketoglutarate and L-carnitine perturbs lipid metabolism, leading to the atypical accumulation of lipids and dyslipidemia. Respiratory chain disruption because of the accumulation of reduced nicotinamide adenine di-nucleotide as a consequence of oxidative stress and the stimulatory effect of aluminum exposure on glycolysis causes many health issues including fat accumulation, obesity, and other hepatic disorders. One major factor contributing to dyslipidemia and enhanced pro-inflammatory responses is estrogen. Aluminum, being a metalloestrogen, modulates estrogen receptors, and in this world of industrialization and urbanization, we could corner down to metals, particularly aluminum, in the development of dyslipidemia. As per PRISMA guidelines, we did a literature search in four medical databases to give a holistic view of the possible link between aluminum exposure and various biochemical events leading to dyslipidemia.
铝是地壳中含量第三丰富的金属,几乎存在于我们使用的所有日常用品中,接触铝不可避免。铝对人体各种生化反应的干扰会导致有害的健康影响,其中铝诱导的神经退行性变受到广泛研究。然而,铝导致血脂异常的影响也不容忽视。血脂异常是一个全球性的健康问题,是导致非传染性疾病的一个因素。铝对三羧酸循环和电子传递链中各种铁依赖性酶活性的干扰导致线粒体三磷酸腺苷生成减少。这最终会导致氧化应激和铁介导的脂质过氧化。这种线粒体功能障碍以及α-酮戊二酸和左旋肉碱的调节会扰乱脂质代谢,导致脂质异常积聚和血脂异常。由于氧化应激导致还原型烟酰胺腺嘌呤二核苷酸积累以及铝暴露对糖酵解的刺激作用而引起的呼吸链破坏会导致许多健康问题,包括脂肪堆积、肥胖和其他肝脏疾病。导致血脂异常和促炎反应增强的一个主要因素是雌激素。铝作为一种金属雌激素,会调节雌激素受体,在这个工业化和城市化的世界里,我们可以将血脂异常的发展归因于金属,尤其是铝。根据PRISMA指南,我们在四个医学数据库中进行了文献检索,以全面了解铝暴露与导致血脂异常的各种生化事件之间可能存在的联系。
