Exercise, Demethylase FTO, Neurological Disorders, and Neuropathic Pain: Potential Molecular Mechanisms

Area of Science:

• Neuroscience
• Epigenetics
• Molecular Biology

Background:

• Fat mass and obesity-associated protein (FTO) is implicated in neurological disorders and neuropathic pain (NP).
• m⁶A modification, regulated by FTO, plays a crucial role in brain regions like the hippocampus and striatum.
• FTO's involvement in NP pathology suggests it as a potential therapeutic target.

Purpose of the Study:

• To review the role of FTO in neurological disorders and neuropathic pain.
• To explore FTO-mediated m⁶A modification mechanisms in these conditions.
• To investigate the potential of exercise as an intervention.

Main Methods:

• Review of existing literature on FTO, m⁶A modification, neurological disorders, and neuropathic pain.
• Analysis of FTO's role in key brain regions and signaling pathways (mTOR, BDNF/TrkB).
• Examination of emerging evidence on exercise's impact on FTO and m⁶A levels.

Main Results:

• FTO-regulated m⁶A modification is critical in Alzheimer's, Parkinson's, depression, and NP.
• Common mechanisms involve mTOR, BDNF/TrkB pathways, neuronal excitability, and synaptic plasticity.
• Exercise may reduce FTO expression and increase m⁶A levels, suggesting epigenetic modulation in the CNS.

Conclusions:

• FTO may be a therapeutic target and biomarker for neurological disorders and NP.
• Exercise could be an effective intervention by downregulating FTO and modulating m⁶A.
• Exercise may offer neuroprotection through enhanced synaptic plasticity and modulated neuronal excitability.
