AIMS To determine the role of lncRNA HOXA11-AS1 on adipocyte differentiation. METHODS Human adipose-derived stem cells (hADSCs) were isolated from adipose tissues of patients and cultured in vitro, followed by knockdown of HOXA11-AS1. Then, adipocyte differentiation and expression of adipogenic-related genes (CEBP-α, DGAT2, CIDEC, and perilipin) were measured by RT-qPCR and Western blot. RESULTS We demonstrated that knockdown of HOXA11-AS1 inhibited adipocyte differentiation, leading to suppression of adipogenic-related gene (CEBP-α, DGAT2, CIDEC, and perilipin) transcription, as well as decreased lipid accumulation in hADSCs. In addition, lncRNA HOXA11-AS1 was highly expressed in obese patients and significantly increased during the process of adipocyte differentiation. CONCLUSION The results provide new insight into the molecular mechanism by which lncRNA HOXA11-AS1 is involved in adipogenesis and may have implications for the treatment of obesity and associated disorders.
