Progesterone receptor expression in the human placenta.
The presence of progesterone receptors (PR) in the human placenta has been demonstrated using the reverse transcriptase-polymerase chain reaction technique. It was observed that the amount of PR in the human placenta is less during late gestation. Electrophoretic mobility shift assays with nuclear extract isolated from the first trimester and term revealed three complexes when incubated with [3...
متن کاملThe isolation of adrenal-like steroids from the human placenta.
In previous studies on the isolation of progesterone from placenta, the presence of steroids altered by the NaOH procedure was suspected (1). This was apparently confirmed in the isolation of progesterone from pooled plasma of pregnant women by the presence of progestationally active material other than progesterone when measured by the Hooker-Forbes bioassay (2). A new analysis of placenta was...
متن کاملMethod for the isolation of progesterone from human placentae.
Evidence for the endocrine r81e of the human placenta has been indicat’ed by manifold physiological experiments; the supporting data for this concept have been reviewed by Newton (1). Lipide extracts of human placenta have been shown to contain progestational activity as determined by the rabbit assay method (2-4). Since the progestational hormone has not been isolated from the placental extrac...
متن کاملIsolation and characterization of a folate receptor from human placenta.
While folate binding proteins have been described in serum and a variety of tissues, the function of these proteins is unknown. A particulate folate binding protein from human placenta has been isolated and characterized following solubilization with Triton X-100. The protein was purified 61,000-fold using affinity chromatography on pteroylglutamic acid-Sepharose as the major purification step....
متن کاملIsolation and characterization of dipeptidyl peptidase IV from human placenta.
Human placenta is surprisingly rich in post-proline dipeptidyl peptidase activity. Among various cell fractions, microsomes have the highest specific activity. A homogeneous enzyme preparation is obtained in a six-step purification procedure. The final preparation appears homogeneous upon dodecyl sulfate electrophoresis, but analytical isoelectric focussing reveals various active bands with iso...
