OBJECTIVE The purpose of this study was (1) to evaluate the potential sites of transforming growth factor-beta 1 synthesis in human endometrium by analyzing separated endometrial glands and stromal cells for transforming growth factor-beta 1 messenger ribonucleic acid by Northern analysis of total ribonucleic acid and (2) to investigate the effects of transforming growth factor-beta 1 on deoxyribonucleic acid synthesis in endometrial epithelial and stromal cells in culture. METHODS Endometrial glands and stroma from proliferative and secretory endometrium were isolated after collagenase treatment of endometrial tissue minces and were analyzed for transforming growth factor-beta 1 messenger ribonucleic acid by Northern analysis. We studied the effects of estradiol-17 beta and transforming growth factor-beta 1 on deoxyribonucleic acid synthesis in endometrial epithelium and transforming growth factor-beta 1 on stromal cells in culture by evaluating tritiated thymidine incorporation into trichloroacetic acid-precipitable material. RESULTS Transforming growth factor-beta 1 messenger ribonucleic acid was detected for Northern analysis in separated endometrial stromal cells in levels that were greatest during the secretory phase and in greater levels than in epithelial cells from that same tissue. Transforming growth factor-beta 1 messenger ribonucleic acid in glandular epithelium in culture was not increased to detectable levels by treatment with transforming growth factor-beta 1. Deoxyribonucleic acid synthesis in endometrial glandular epithelium was inhibited by transforming growth factor-beta 1, but transforming growth factor-beta 1 stimulated deoxyribonucleic acid synthesis in endometrial stromal cells in culture. After treatment for 5 days with estradiol-17 beta (10(-8) mol/L), deoxyribonucleic acid synthesis in endometrial glands in culture was decreased by 40%. Transforming growth factor-beta 1 (1 ng/ml) did not alter this effect of estradiol-17 beta on deoxyribonucleic acid synthesis. CONCLUSIONS Transforming growth factor-beta 1 acts to decrease deoxyribonucleic acid synthesis in epithelial cells and to increase it in stromal cells isolated from human endometrium and maintained in monolayer culture. Transforming growth factor-beta 1, potentially of stromal cell origin, could participate in the regulation of endometrial cell proliferation and differentiation in vivo.

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D004717 Endometrium The mucous membrane lining of the uterine cavity that is hormonally responsive during the MENSTRUAL CYCLE and PREGNANCY. The endometrium undergoes cyclic changes that characterize MENSTRUATION. After successful FERTILIZATION, it serves to sustain the developing embryo. Endometria

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.

D016212 Transforming Growth Factor beta A factor synthesized in a wide variety of tissues. It acts synergistically with TGF-alpha in inducing phenotypic transformation and can also act as a negative autocrine growth factor. TGF-beta has a potential role in embryonal development, cellular differentiation, hormone secretion, and immune function. TGF-beta is found mostly as homodimer forms of separate gene products TGF-beta1, TGF-beta2 or TGF-beta3. Heterodimers composed of TGF-beta1 and 2 (TGF-beta1.2) or of TGF-beta2 and 3 (TGF-beta2.3) have been isolated. The TGF-beta proteins are synthesized as precursor proteins.
