CNR1 and gestational diabetes: The study of two endocannabinoid receptors, CB1 and TRPV-1, in the whole placenta samples did not reveal any statistical differences between the levels of control and pathological samples (GDM p = 0.9346 and SGA p = 0.5094 for CB1; GDM p = 0.5313 and SGA p = 0.9029 for TRPV-1; n = 12) (Supplementary Figure S1A).
