FTO-mediated m6A modification regulates the osteogenic differentiation of ADSCs by targeting FOXO1.

ABSTRACT: Using adipose-derived stem cells (ADSCs) has recently become a crucial approach for treating bone defects owing to their ease of accessibility and substantial differentiation potential. N6-methyladenosine (m6A) modification greatly influences biological processes and determines the differentiation fate of stem cells. However, the specific mechanisms by which m6A modification influences the osteogenic differentiation of ADSCs remain unclear. We identified FOXO1 as the key m6A-modified gene during the osteogenesis of ADSCs. Furthermore, demethylase FTO enhanced RUNX2 expression while inhibiting PPARG expression by modifying FOXO1, thereby facilitating ADSC osteogenesis. FTO knockdown inhibited ADSC migration and proliferation and impaired osteogenesis by suppressing FOXO1. At the mechanistic
