LncRNA/mRNA expression profile of rat bone marrow mesenchymal stem cells (BMSCs) under hypoxia condition

The osteonecrotic area of steroid-induced avascular necrosis of the femoral head (SANFH) is a hypoxic microenvironment that leads to apoptosis of transplanted bone marrow mesenchymal stem cells (BMSCs). However, the underlying mechanism remains unclear. Here, we explore the mechanism of hypoxic-induced apoptosis of BMSCs, and use the mechanism to improve the transplantation efficacy of BMSCs. We analyzed LncRNA/mRNA expression profile of BMSCs under hypoxia conditions, and successfully screened the key long non-coding RNA AABR07053481 (LncAABR07053481) which mediated hypoxic apoptosis of BMSCs, we further determined its regulatory mechanism. Importantly, overexpression of LncAABR07053481 can improve the survival rate and repair efficacy of BMSCs under hypoxia conditions.
