Establishing an Oxidative Stress Model in the Human Mesencephalic Cell Line (LUHMES): an in vitro study

Abstract

Oxidative stress-caused neurodegenerative diseases, such as Alzheimer's, Parkinson's disease, and amyotrophic lateral sclerosis, are widely recognized as the most prevalent brain and central nervous system disorders. This is attributed to the vulnerability of neurons to oxidative stress within the body. Although substantial research has been performed on these diseases, it is extremely difficult to establish an oxidative stress model for brain tissues. In primary cultures, it is difficult to obtain neurons and the continuity of the culture is limited for in vitro cell line models. By providing valuable insights into the mechanisms of oxidative stress-induced neurodegenerative diseases, these in vitro models can aid in the development of effective treatment strategies. Here, we developed an in vitro oxidative stress model utilizing hydrogen peroxide on the LUHMES cell line. Our study evaluated the impact of this model on LUHMES cell viability and the equilibrium between oxidants and antioxidants by assaying total oxidant capacity (TOC) and total antioxidant capacity (TAC). Our results provided evidence of the oxidative effect of hydrogen peroxide in critical concentration and proved the efficacy of this model for further investigations.
