RNA-seq Analysis of Changes in mRNA Expression for the hTERT-HMA/B Human Myometrial Cell Line treated with all Combinations of Progesterone, Forskolin, and Interleukin-1β

ABSTRACT: Parturition involves cellular signaling changes driven by the complex interplay between progesterone (P4), inflammation, and the cyclic adenosine monophosphate (cAMP) pathway. To characterize this interplay, comprehensive transcriptomic studies utilizing 8 treatment combinations were performed on the hTERT-HMA/B telomerase immortalized human myometrial cell line and myometrium obtained from term c-section deliveries. Genome-wide RNA-sequencing was performed on total RNA extracted from hTERT-HMA/B cells treated with all combinations of P4, forskolin (induces cAMP), and interleukin-1β (IL-1β). Gene set enrichment and regulatory network analyses was then used to identify pathways commonly, differentially, or synergistically regulated by each treatment. Tissue similarity index (TSI) was also applied to characterize the correspondence between cell lines and tissue phenotypes. In addition to their individual anti-inflammatory effects, P4 and cAMP synergistically blocked specific inflammatory pathways/regulators including STAT3/6, CEBPA/B, and OCT1/7, but not NFKB. TSI analysis indicated that forskolin+P4- and IL-1β-treated cells exhibit transcriptional signatures highly similar to non-laboring and laboring term myometrium, respectively. The data identify potential therapeutic targets to prevent preterm birth and show that the hTERT-HMA/B cell line provides is an accurate transcriptional model for term ± labor myometrium.

Expression of Cyclic AMP associated genes on primary culture human myometrial cells

Project description:During pregnancy, the myometrium remains quiescent but at term, switches to a state capable of producing a series of coordinated contractions for the delivery of the fetus. Myometrial contractions of labour signify the normal physiological end-point of pregnancy but the biochemical onset of labour may occur at or before term via a series of changes in expression of labour associated genes that are responsible for controlling the activity of the uterus during pregnancy and parturition. There is increasing evidence that components of the cAMP-signalling pathway are up-regulated in the human myometrium during pregnancy to promote the relaxation of the myometrium until term. Our aim was to determine which cAMP-associated genes are important during pregnancy and parturition by exposing myometrial cells to forskolin and performing an a gene array. We then plan to study the trend of the cAMP-associated genes at different stages of gestation and during labour. In this study, we used microarrays to elucidate forskolin responsive genes in human myometrium. These data may provide a broader view of gene networks and cellular functions regulated by forskolin in human myometrial cells. In our future study, this will also help us understand the role of cAMP in human parturition. Primary cultures of human myometrial cells were grown from myometrial biopsies obtained at the time of elective caesarean section at term. Cells were exposed to forskolin (100 ÂµM) for 48 hours, and then total RNA were extracted from each culture. Two comparisons were carried out including: 1. Control 2. Forksolin

Gene expression in response to short and long term cAMP stimulation in the INS-1 insulinoma cell line

Project description:Long term exposure to incretin hormones is known to have salutory effects on beta cell function and viability. While short-term cAMP induction is known to have a signature CREB-CRTC target gene response, the long-term effects of cAMP on beta cell gene expression are less well understood. We used rat microarray analysis to compare the genome-wide gene expression response to short-term (2 hours) and long-term (16 hours) stimulations of the cAMP agonist forskolin in INS-1 insulinoma cells. INS-1 cells were exposed to forskolin for 2 or 16 hours in RPMI medium containing 10% serum. Control samples wer incubated for the same time without forskolin. Extracted RNA was used for hybridization on Affymetrix rat 1.0 st gene arrays.

Expression data from primary culture human myometrial cells

Project description:Inflammation plays a central role in many human diseases. Human parturition also resembles an inflammatory reaction, where progesterone (P4) and progesterone receptors (PRs) have already been demonstrated to suppress contraction-associated gene expression. In our previous studies, we have found that the progesterone actions, including progesterone-induced gene expression and progesterone’s anti-inflammatory effect, are mediated by PR, GR or both. In this study, we used microarrays to find P4 and IL-1β responsive genes and which IL-1β responsive genes were repressed by P4. These data may provide a broader view of gene networks and cellular functions regulated by P4 and IL-1βin human myometrial cells. In our future study, this will also help us understand the role of PR and GR in human parturition. Primary cultures of human myometrial cells were grown from myometrial biopsies obtained at the time of elective caesarean section. Cells were exposed to different stimuli, IL-1β (5ng/mL) and P4 (10 µM), either alone or in combination for 6 h, and then total RNA were extracted from each culture. Three comparisons were carried out including: 1. V vs. P4; 2. V vs. IL-1β; 3. IL-1β vs. IL-1β+P4.

Comparison of the in vivo transcriptome of the myometrium to the transcriptome of myometrial explants, primary cultured myometrial cells and the hTert myometrial cell line

Project description:Circulating progesterone (P4) levels decline before the onset of parturition in most animals, but not in humans. This has led to the suggestion that there is functional withdrawal of P4 action at the myometrial level prior to labor onset. Mifepristone is widely used to induce human labour In this study, we aimed to establish and validate a model of human myometrial explants for the study of P4 action. Myometrial biopsies obtained at Caesearean section at term were dissected into explants after a portion was immediately snap-frozen (t=0). Transcriptomic comparison of paired explants and primary myometrial cells as well as the hTert immortalized myometrial cell line demonstrated that explants more closely resemble t=0. Biopsies obtained from non-laboring women at elective Caesarean section at term were divided into 3: (i) dissected and immediately snap-frozen (t=0), (ii) dissected into 3x3x3mm3myometrial explants and (iii) processed for primary cell culture. Explants, primary cells at passage 4 (the typical passage our group uses for experiments) and hTERT cells were cultured for a period of 30 hours without treatment. Total RNA was extracted and microarray analysis performed. 6 replicates were used for this study.
