OBJECTIVE To examine the spatiotemporal expression and regulation of prostaglandin transporter (PGT), 15-hydroxy-PG dehydrogenase (15-PGDH), and carbonyl reductase 1 (CBR1) messenger RNA (mRNA) and protein in the mouse uterus during embryo implantation and in related models. METHODS Experimental animal study. METHODS University research laboratory. METHODS Sexually mature female Kunming strain white mice. METHODS Delayed and activated implantation, artificial decidualization, and subcutaneous injection of progesterone (P) and E(2) in ovariectomized mouse. METHODS The expression of mRNA and protein were detected by in situ hybridization and immunohistochemistry in mouse uterus. RESULTS Prostaglandin transporter mRNA and protein were expressed in the subluminal stroma at implantation site on day 5 of pregnancy and then in decidua but were not detected at the interimplantation sites and in preimplantation or pseudopregnant uterus. The presence of an active blastocyst was required for PGT expression at the implantation site. Both 15-PGDH and CBR1 mRNA were detected in glandular epithelium on day 4 of pregnancies. The expression of 15-PGDH and CBR1 mRNA was also detected in postimplantation embryos. CONCLUSIONS These data suggest that differentially expressed PGT and 15-PGDH may participate in PG signaling in mouse uterus during implantation and decidualization.

D015398 Signal Transduction The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
