PPARG and gestational diabetes: PPARγ is widely regarded as a key transcription factor in adipocyte differentiation41,42 and as PC-O(34:1) is much more abundant in infants from GDM pregnancies than controls, we might predict that more of the oxidised form (oxPC-O(34:1), which is commercially available) in circulo and that this leads to higher activation of PPARγ in SGA and MHG infants.
