Abstract
Objectives The main aim of this study is to identify the deleterious effects of indiscriminately consumed high fructose on motor neurons that are critically affected in many neurological conditions causing movement disorders including paralysis. Materials and Methods Neuroblastoma x mouse spinal cord motor neuron cell line (NSC-34) motor neuron cell lines were treated with high fructose and oxygen supplementation (18.8%) and assayed for cell proliferation/death, reactive oxygen species (ROS) generation, and oxidative stress response induction Statistical Analysis Mean and standard deviation, significance with and without high fructose (F)-5%, were estimated by t -tests using GraphPad Prism ver. 8.2.1 Results F-5% along with O 2 (18.8%) annihilates the cells ( approximately 85%) by day10 and inhibits cell division as observed by the presence of multinucleated cells. Unexpectedly, 1 to 2% of cells that survived, differentiated and displayed progressive neurite extension. Though not healthy, they were viable up to 80 days. F-5% increased ROS levels ( approximately 34%) not accompanied by concomitant enhanced expression of oxidative stress response regulator, the transcription factor, nrf-2 , or downstream effector, sod-1. Conclusion High fructose is extremely harmful to NSC-34 motor neuron cell line.
