We evaluated the changes in mRNA expression of cytosolic phospholipase A(2)(cPLA(2)) and 15-hydroxyprostaglandin dehydrogenase (PGDH) in intrauterine and gestational tissues during mid-late murine pregnancy. Tissues (decidual caps, fetal membranes, and placentae, uterus, and cervix) were collected from pregnant mice at days 12, 14, 16, 18, and 19 (am and pm) of gestation. Total RNA was isolated and evaluated for cPLA(2)and PGDH expression by northern blot analysis normalized to GAPDH expression. Expression of mRNA for cPLA(2)increased in the placentae and decidual caps on day 18 and 19 pm, respectively. There was also increased expression for PGDH mRNA in the placenta and fetal membranes at the later stages of pregnancy. The tissue specific differences in expression of cPLA(2)and PGDH suggest that changes in enzymatic regulation of PG production and degradation may be crucial for the initiation of labour.

D004622 Embryo, Mammalian The entity of a developing mammal (MAMMALS), generally from the cleavage of a ZYGOTE to the end of embryonic differentiation of basic structures. For the human embryo, this represents the first two months of intrauterine development preceding the stages of the FETUS.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012313 RNA A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. RNA is unique among biological macromolecules in that it can encode genetic information, serve as an abundant structural component of cells, and also possesses catalytic activity.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
