RNA sequence for macrodactyly ADSCs
Macrodactyly is a congenital malformation characterized by enlargement of bone and soft tissues in limbs, typically with excessive accumulation of adipose tissues. Although gain-of-function mutation of PIK3CA has been identified in macrodactyly, the mechanism of PIK3CA mutation in adipose accumulation is poorly understood. In this study, we found that adipocytes from macrodactyly were more hypertrophic than those observed in polydactyly. PIK3CA (H1047R) activating mutation and enhanced activity of PI3K/AKT pathway were detected in macrodactylous adipose-derived stem cells (Mac-ADSCs). To identify the key downstream effectors of PIK3CA activation-mediated adipogenesis in Mac-ADSCs, we examined the transcriptome of Mac-ADSCs, BYL-719 treated Mac-ADSCs  and Pol-ADSCs by RNA-Seq analysis. Overall design: macrodactyly,polydactyly and macrodactyly+BYL-719
