title: Growth hormone receptor and growth hormone-binding protein messages in mouse placenta contain the exon analogous to human exon 3.
abstract: Growth hormone receptor (GHR)-encoding messages from the human placenta and other tissues have been recently characterized by several investigators. Of particular interest is the finding that exon 3 is deleted from the mRNA encoding GHR in human placenta, but not in maternal tissues. We have used a reverse transcriptase-polymerase chain reaction (RT-PCR) technique to amplify the distinct mRNAs encoding GHR and GH-binding protein (GHBP) in the mouse placenta and liver, followed by restriction analysis, to determine whether an analogous deletion exists in these mRNAs. The restriction analysis and sequencing of the PCR products shows that the mRNAs encoding GHBP and GHR in the mouse placenta do not have a deletion analogous to that found in human placental GHR mRNA.
