Readily derived from D-glucose, 5-[(2R,3S,4R)-3,4-dihydroxypyrrolidin-2-yl]-2-methyl-3-furoic esters and amides are selective and competitive inhibitors (K(i)greater than or equal to3 muM) Of alpha -L-fucosidase from bovine epididymis and from human placen ...
PPAR-gamma/RXR heterodimers play a key regulatory role in murine placental development. We report here that PPAR-gamma and RXR-alpha are highly expressed in cultured primary extravillous cytotrophoblasts (EVCT) isolated from human first-trimester placenta. ...
Pulsations in the fetal heart propagate through the precordial vein and the ductus venosus but are normally not transmitted into the umbilical vein. Pulsations in the umbilical vein do occur, however, in early pregnancy and in pathological conditions. Such ...
Leptin, a small peptide produced by adipocytes, is implicated in an increasing number of endocrine regulations, including adiposity, satiety, puberty, and fertility. Although the factors involved in controlling maternal and fetal weight gain during pregnan ...
Recent studies performed with null mice suggested a role of either RXR alpha or PPAR gamma in murine placental development. We report here that both PPAR gamma and RXR alpha are strongly expressed in human villous cytotrophoblasts and syncytiotrophoblasts. ...
The ligand-dependent nuclear receptors PPARgamma and RXRalpha/beta were recently determined to be essential for murine placental development and trophoblast differentiation. In the current study we examined the expression and role of the PPARgamma/RXRalpha ...
We describe a simple method for the affinity purification of specific RNA-binding proteins. DNA sequences corresponding to the protein-binding site of the RNA are subcloned into an in vitro transcription vector between the T7 viral promoter and a poly(A) t ...
