Reactive oxygen species regulate adipose-osteogenic lineage commitment of human mesenchymal stem cells by modulating gene expression of C/EBP homology protein and aldo-keto reductase family 1 member A1.

ABSTRACT:

Background

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.

Results

Our findings demonstrate that increased ROS levels enhance the expression of C/EBP homology protein (CHOP) and Akr1A1 du
