Emerging evidence has suggested that N -methyladenosine (m A) regulates the pathology of Parkinson's disease (PD). Nevertheless, the function of demethylase fat mass and obesity (FTO) associated pathogenesis is still not fully elucidated. Here, this research findings revealed that m A-modification was decreased in PD models, meanwhile, the FTO level upregulated in the PD models. Functionally, in N-methyl-4-phenylpyridinium (MPP+) treated SH-SY5Y cells, the ferroptosis significantly upregulated and FTO silencing mitigated the ferroptosis phenotype. Moreover, in silico assays indicated that nuclear factor erythroid 2-related factor-2 (NRF2) acted as the target of FTO, and FTO demethylated the m A modification from NRF2 mRNA. Furthermore, FTO impaired the NRF2 mRNA stability via m A-dependent pathway. Thus, our findings illustrated an important role of FTO on PD through m A-NRF2-ferroptosis manner. Taken together, the study revealed the potential function of FTO on PD nervous system diseases.

Pulmonary arterial hypertension (PAH) is a syndrome characterized by increased pulmonary vascular resistance and elevated pulmonary artery pressure, ultimately leading to right heart failure and even death. Increasing evidence implicates the fat mass and obesity-associated protein (FTO) in various metabolic and inflammatory pathways; however, its role in pulmonary endothelial function and PAH remains largely unexplored. In this study, we examined the effects of endothelial cell-specific FTO knockout on PAH development.

From a current perspective, it is understood that body posture is influenced by individual asymmetries, cultural context, habitual body patterns, etiological factors and psychosocial factors allocated to the individual. Clarifying the musculoskeletal cause that originated the postural alteration is considered the clinical challenge in the treatment of pain or discomfort. Recent studies have shown the influence of changes in body weight on the distribution of plantar pressure and foot pain, emphasizing the importance of understanding these relationships.

Background: The impact of fatty liver disease on lumbar bone mineral density (BMD) represents an intriguing area of study, particularly in light of established research linking obesity to bone metabolism. However, there remains limited investigation into the correlation between quantifying liver fat content (LFC) and lumbar BMD among overweight and obese populations, particularly within the Chinese demographic. This study aims to accurately quantify LFC and investigate its association with lumbar BMD in overweight or obese individuals.

Background: The current study investigated the effects of high-fat diet on acute response to 3,4-methylenedioxypyrovalerone (MDPV) in mice. MDPV is a beta-cathinone derivative endowed with psychostimulant activity. Similarly to recreational substances, consumption of palatable food stimulates the mesolimbic dopaminergic system, resulting in neuroadaptive changes.
