Abstract
Obesity is primarily characterized by the accumulation of large amounts of fat in adipose tissue. Within the adipose tissue, adipocytes are derived from adipose tissue-derived stromal cells (ADSCs) via a specialized cell lineage differentiation process, and ADSCs play a key role in the generation and metabolism of adipose tissue. This study investigated whether microRNAs (miRNAs) play a role in adipocyte differentiation. Using luciferase reporter and ChIP assays, the relationship between miR-29b, SP1, and TNF-α was examined. During the normal adipogenic differentiation of ADSCs, up-regulation of miR-29b promoted adipogenesis by enhancing SP1-mediated inhibition of TNF-α. This study investigated the regulatory role of miR-29b during the adipogenic differentiation of ADSCs and found that miR-29b is an effective positive regulator of adipogenesis.
