TAZ-mediated enhancement of adipogenesis in goat adipose mesenchymal stem cells induced by TNF-α


ABSTRACT: Obesity is a clinical condition characterised by a chronic, low-grade inflammatory state. Adipose-derived mesenchymal stem cells (ADSCs) have a multidirectional differentiation potential to adipocytes. However, the relationship between adipogenesis and inflammation is not yet fully understood.TAZ (WW domain containing transcription regulator 1) can act as a molecular rheostat to fine-tune the osteoblast and adipocyte differentiation balance. In this study, we investigated the role of TAZ in the adipogenesis of Arbas cashmere goat ADSCs (gADSCs). We observed elevated TAZ expression levels during the adipogenesis of gADSCs. Overexpression and knockdown of TAZ were performed in stably transfected gADSCs cell lines, and RNA-seq analysis revealed that TAZ was associated with adipogenesis. TAZ overexpression promoted adipose differentiation of gADSCs, while TAZ knockdown had the opposite effect. In addition, TAZ overexpression and knockdown altered the expression of YAP1 (Yes1 associated transcriptional regulator) and TAZ in the nucleus. TAZ regulated the mRNA expression level and secretion level of tumor necrosis factor (TNF)-α, promoting adipose differentiation of gADSCs. Notably, TNF-α counteracted the inhibitory effect of sh-TAZ on the adipose differentiation of gADSCs. Collectively, these findings suggest that TAZ regulates adipogenesis in gADSCs by modulating TNF-α, which is of particular significance in several metabolic disorders where the amount or function of adipose tissue is altered.
