Emerging Roles of FTO in Neuropsychiatric Disorders

Abstract: FTO (fat mass and obesity associated) is a recently discovered gene related to obesity and expressed in various tissues of the human body, especially with high expression in the brain. Earlier studies have found that FTO is involved in several biological processes, including brain development and function. In particular, recent studies have found that FTO is a demethylase of N6-methyladenosine (m6A) and it can affect neurological function through the m6A modification of mRNA. At present, a number of studies ha… Show more

“…The two most significant loci exerted opposite directions of effect for BMI and AUD. The first was an intronic variant (rs9939973) in the well-known obesity risk gene, FTO (also linked to numerous other traits, including substance use disorders, major depression, and schizophrenia; Chang et al, 2022). The second was an intronic variant (rs13114738) in the highly pleiotropic gene SLC39A8 (Pickrell et al, 2016).…”

“…M6A is first converted to hm6A, then transformed to fm6A, and finally reduced to original adenylate ( 34 , 35 ). FTO is enriched in brain, especially in neurons, and plays an important regulatory role in central nervous system (CNS), including brain development and function ( 36 ). Dysregulation of FTO may participate in CNS injuries such as TBI.…”

“…With the recent advent of epitranscriptomic modification, such dynamism in gene regulation may occur in concert with m 6 A RNA methylation, the most prevalent type of epitranscriptomic modification in the brain ( Chang et al, 2017 ). In this context, it is important to note that FTO plays a significant role not only in the processing of m 6 A enrichment on a gene, but it has a direct role in brain development and function ( Widagdo and Anggono, 2018 ; Chang et al, 2022 ). The FTO gene is abundantly expressed in the brain and participates in neurogenesis ( Li et al, 2017b ; Gao et al, 2020 ; Du et al, 2021 ) and memory deficits ( Walters et al, 2017 ; Spychala and Ruther, 2019 ; Leonetti et al, 2020 ).…”
