Description

This pathway illustrates signaling networks implicated in uterine muscle contraction at labor and quiescence throughout gestation (pregnancy). The muscle of the uterus, responsible for contractile activity is the myometrium. Genes in this pathway are either transcribed in myometrial muscle cells or act upon the myometrium to regulate contraction. The left half of this pathway illustrates pathways of myometrial relaxation that are active throughout normal gestation. These signaling events act to suppress coordinated contractions to prevent the early onset of labor at term, largely via activation of the adenylyl-cyclase thrhough G-protein coupled receptors. On the right side of this pathway are signaling componets involved in the activation of uterine contractions at labor, in particular, activation of calcium mobilization via Oxytocin mediated binding to the Oxytocin G-protein coupled receptor. Additional genes implicated in this pathway, based on microarray expression profiling of gestation, term and postpartum of term mice are also included (e.g., Guca2b, Rdc1, Edg2) have also been included. For a detailed description of this pathway see: http://genomebiology.com/2005/6/2/R12.

Rozen F, Russo C, Banville D, Zingg HH PMID: 7816817 quote: The presence of APREs in the OTR gene promoter suggests that the acute induction of OTR expression at the onset of parturition may be a phenomenon mechanistically similar to the fast induction of acute phase response genes. This notion is strengthened by the observation that the uterus is populated by macrophages and other specific lymphocytes (19,20). Specifically, at term, nearly half of the decidual cells are of bone marrow origin (20). IL-1beta released from macrophages stimulates the production and release of IL-6 by uterine stromal cells (21,22). Moreover, IL- is a central pathophysiological mediator of infection-induced premature delivery (23), and preterm delivery can be prevented by an IL-1 antagonist in mice (24). We speculate that under physiological as well as phathophysiological conditions, inflammatory cytokines are important inducers of labor and that this mechanism involves the cytokine-induced transcriptional activation of the OTR gene. :end quote

MAFFGeneProduct23764 (Entrez Gene) OMIM: Inoue et al. (1994) demonstrated that the US-2 element in the promoter of the human oxytocin receptor gene (OXTR; 167055) binds specifically nuclear proteins from human myometrium at parturition. Using the US-2 element in a yeast 1-hybrid system to screen a human myometrium cDNA library, Kimura et al. (1999) isolated a full-length cDNA encoding the homolog of chicken MafF. Human MAFF encodes a deduced 164-amino acid protein with a predicted molecular mass of 17.8 kD. Like other small MAF proteins (e.g., MAFG, 602020), it contains an extended leucine zipper structure and lacks an N-terminal transactivating domain. Northern blot analysis showed a strong 2.6-kb signal in mRNA from term myometrium and from kidney, but not from nonpregnant myometrium. The MAFF protein is also preferentially expressed in term myometrium. The authors concluded that MAFF plays a role in OXTR gene upregulation at term.
