Characterization of cellular retinoid-binding proteins in human myometrium during pregnancy.

Identification of genes with higher expression in human uterine leiomyomas than in the corresponding myometrium.

We used a PCR-based subtraction method, representational difference analysis of cDNA (cDNA--RDA), to identify genes with a higher expression in leiomyomas in comparison with the corresponding myometrium during the proliferative phase of the menstrual cycle. Increased expression of the genes for pregnancy-associated plasma protein A (PAPPA), tomoregulin, cellular retinoid acid binding protein 1 ...

Retinoic acid pathway genes show significantly altered expression in uterine fibroids when compared with normal myometrium.

Fibroids are benign neoplasms of myometrial smooth muscle cells (SMC). Despite being the most common tumor in humans, their etiology is poorly understood. Recent microarray studies have demonstrated that multiple members of the retinoid pathway are differentially expressed between myometrium and fibroids. The aim of this present study was to investigate gene expression of members of the retinoi...

Characterization and functional analysis of cAMP response element modulator protein and activating transcription factor 2 (ATF2) isoforms in the human myometrium during pregnancy and labor: identification of a novel ATF2 species with potent transactivation properties.

There is now extensive evidence to indicate that components of the cAMP signaling pathway are up-regulated in the human myometrium during pregnancy so as to potentiate the maintenance of uterine quiescence until term. In many tissue and cell types, increased signaling of the cAMP pathway results in profound changes in gene expression that are catalyzed via stimulation of PKA and activation of c...

Application of a functional genomics approach to identify differentially expressed genes in human myometrium during pregnancy and labour.

The molecular mechanisms regulating uterine relaxation and contraction during pregnancy are poorly understood. In the present study, we used for the first time a functional genomics approach applying gene array technology to identify novel candidate genes involved in the regulation of uterine quiescence and contractility during pregnancy. The purpose of this approach was to obtain a molecular s...
