Abstract

Major health issues like cancer and neurological diseases are caused due to excessive exposure or accumulation of metals like iron, zinc, and copper. The distribution of these elements is regulated by metal homeostasis, which is crucial for maintaining vital cellular functions, including oxygen transport, immune defense, and cellular energy management. The body retains metal homeostasis through mechanisms that control absorption, transport, and storage of these metals. When these regulatory processes malfunction, they give rise to disorders, such as hemochromatosis and Wilson’s disease, which can lead to zinc deficiency. Notably, in neurodegenerative diseases like Alzheimer’s and Parkinson’s, disrupted metal regulation contributes to disease progression through inflammation, oxidative stress, and impaired molecular signalling, all of which aggravate neuronal damage and interfere with neurotransmitter activity. To better understand these mechanisms, researchers use animal models and virtual computer-based models to study how metal imbalance initiates and sustains disease states. Progress in treatment evaluation relies on transitioning from preclinical findings to clinical trials to assess both safety and effectiveness. Recently, computational tools have merged with personalized medicine, using computational software to develop innovative approaches for managing metal-related disorders. These studies focus on tracking biological mechanisms of metals and their links to brain damage, aiming to apply simulation strategies in future research on metal regulation.
