Aluminum‐induced defective mitochondrial metabolism perturbs cytoskeletal dynamics in human astrocytoma cells

Abstract: Although aluminum (Al), a known environmental toxin, has been implicated in a variety of neurological disorders, the molecular mechanism responsible for these conditions is not fully understood. In this report, we demonstrate the ability of Al to trigger mitochondrial dysfunction and ineffective adenosine triphosphate (ATP) production. This situation severely affected cytoskeletal dynamics. Whereas the control cells had well-defined structures, the Al-exposed astrocytoma cells appeared as globular structures. … Show more

“…During the fermentation reactions, the substrate is only partially oxidized, and therefore, only a small amount of the energy stored in the substrate is conserved (Khanal 2008). The major portion of the adenosine triphosphate (ATP) or energy is generated by substrate-level phosphorylation (Sgarbi et al 2009;Lemire et al 2009;Atlante et al 2005). Anaerobic respiration on the other hand requires external electron acceptors for the disposal of electrons released during the degradation of organic matter.…”

“…Severe impairment of astrocyte function has been demonstrated in conjunction with aluminum exposure [72,73]. Aluminum appears to interfere with iron-sulfur clusters in the mitochondria, causing impaired ATP synthesis, excess production of reactive oxygen species, and impaired formation of the cytoskeleton, which is essential for the cell's function in maintaining the health of neighboring neurons.…”

“…These are all potential indicators of penetration of the aluminum into the brain, as a direct consequence of an inability to properly dispose of the aluminum due to the sulfate deficiency. Aluminum's negative impact on brain function is well established [93][94][95][96][97][98][99][100][101].…”

“…Aluminum has been identified as a factor in chronic fatigue syndrome [92], and it is known to have extensive negative impact on the brain [93][94][95][96][97][98][99][100][101], if it cannot be properly disposed of by the body. Patients with macrophagic myofasciitis often experience cognitive and memory deficits in addition to chronic fatigue.…”
