Abstract (original English)

Bone-derived mesenchymal stem cells (BMSCs) are multipotent stem cells capable of differentiating into adipocytes and osteoblasts. Dysfunctional differentiation, characterized by a shift from osteoblastogenesis to adipogenesis, is closely associated with metabolic and senile osteoporosis. The Aldo-keto reductase family 1 member A1 (Akr1A1) enzyme, which utilizes NADPH to reduce aldehyde groups to alcohols, has emerged as a potential regulator. This study investigates the role of reactive oxygen species (ROS) in modulating Akr1A1 expression during the lineage differentiation of human mesenchymal stem cells into osteoblasts and adipocytes. Our findings demonstrate that increased ROS levels enhance the expression of C/EBP homology protein (CHOP) and Akr1A1 during adipogenic differentiation. Conversely, reduced ROS levels suppress CHOP and Akr1A1 expression in osteogenically committed cells. Functional studies involving Akr1A1 silencing and overexpression revealed that Akr1A1 expression levels dictate MSC lineage commitment without altering ROS production or CHOP expression. Knockdown of Akr1A1 suppressed adipogenesis while promoting osteoblastogenesis, accompanied by upregulation of SIRT1, PGC-1α, TAZ, and other osteogenic transcription factors. In contrast, overexpression of Akr1A1 reduced SIRT1, PGC-1α, and TAZ levels, thereby enhancing adipogenesis and inhibiting osteogenesis.
