Bone-fat phenotype in POH



Bone-fat phenotype in POH

  • Bone-fat phenotype in POH

  • Osteoblast differentiation and HO

  • Adipocyte differentiation and leaness

  • Mechanisms of bone-fat reciprocity



Rare genetic condition of progressive heterotopic bone formation

  • Rare genetic condition of progressive heterotopic bone formation

  • Defined clinically by cutaneous ossification that progresses to involve deep connective tissues including skeletal muscle and fascia [Kaplan et al., 1994]

  • Most cases are caused by heterozygous inactivating germline mutations in the GNAS gene that encodes the alpha subunit of the G-stimulatory protein of adenylyl cyclase [Shore et al., 2002]

  • Bone-fat phenotpye in POH

  • Osteoblast differentiation and HO

  • Adipocyte differentiation and leaness

  • Mechanisms of bone-fat reciprocity

Unlike other GNAS-based disorders of HO, POH occurs in the absence of obesity and multiple other features of AHO or hormone resistance

  • Unlike other GNAS-based disorders of HO, POH occurs in the absence of obesity and multiple other features of AHO or hormone resistance

  • Impaired bone-fat reciprocity in soft tissue promotes osteogenesis and antagonizes adipogenesis in POH

  • GNAS is a key factor which regulates cell fate decisions in adipose-derived stem cells
