In patients with T2DM, stearoyl-CoA desaturase-1 (SCD1) can inhibit the expression of miR-1908-5p and up-regulate the expression of EXO1, thereby promoting the osteogenic differentiation of bone marrow mesenchymal stem cells and ultimately inhibiting the occurrence of fractures in T2D patients (20). The gene discussed is EXO1; the disease is type 2 diabetes mellitus.
