Project description:We examined the global gene expression pattern of T cells regulated by progesterone to gain further insights into the regulatory mechanisms of progesterone. We found 325-347 cord blood T cell genes up or down-regulated by P4 in the presence or absence of exogenous TGFb1. Peripheral blood T cells were relatively unresponsive with only 30-70 genes regulated by P4. IL-6 receptor (IL-6R) expression was greatly down-regulated by progesterone in cord blood, but not PB, T cells. Overall, these differences in gene expression are consistent with the differential responses of cord blood and peripheral blood T cells to progesterone. To gain insights into the differences of progesterone and control dendritic cells, we performed a microarray study and found ~180 genes regulated by progesterone in dendritic cells. The gene expression information suggests that progesterone has the potential to alter dendritic cell responses to cytokines, chemokine production, and migration which in combination would control T cell differentiation. The CD4+ CD25- T cells were isolated from cord blood and peripheral blood and cultured in the presence and absence of progesterone 2 ug per mL, TGFb1 150 pg/mL and IL-2 100u/mL for 5-6 days. T cells from cord blood and peripheral blood were compared.

Project description:The myometrium is an important reproductive tissue composed primarily of smooth muscle cells. Contractility of the myometrial smooth muscle cells during pregnancy and labour is modulated by hormones. Despite much research, little is known about the molecular mechanism by which estrogen and progesterone regulate myometrial contractility. This study investigates global gene expression profile of cultured human uterine smooth muscle cells (hUtSMCs) following 17β-estradiol (E2) and/or progesterone treatments using cDNA microarray technology. Furthermore the effects of addition of the progesterone inhibitor RU486 were investigated. Many genes were regulated in the presence of P4 or E2 alone but almost six times these numbers were regulated in the presence of the combination. The majority of these genes returned to near baseline levels (control samples) on addition of RU486. In total 796 annotated genes were significantly differentially expressed in the combined presence of P4 and E2 (relative to untreated levels). Furthermore, 666 annotated genes were significantly regulated by the addition of RU486 to the P4/E2 combination (relative to P4/E2 levels). Gene ontology analysis of these differentially expressed genes revealed a strong association of P4/E2 treatment with the downregulated expression of genes involved in cell communication, signal transduction, channel activity, inflammatory response and differentiation. Upregulated processes included cell survival (anti-apoptosis), gene transcription, steroid hormone biosynthesis, muscle development, insulin receptor signaling and cell growth. Functional withdrawal of progesterone using RU486 effectively reversed the processes induced by P4/E2 treatment. The hUtSMC system is an additional useful model to investigate steroid effects on smooth muscle cells in isolation from other myometrial cell types.

The hUtSMC system is an additional useful model to investigate steroid effects on smooth muscle cells in isolation from other myometrial cell types. In this study human myometrial smooth muscle cells (hUtSMCs) purchased from Lonza were cultured and treated with 17beta estradiol and progesterone either alone or in combination. In addition the 17beta estradiol and progesterone combined treated samples were also treated with the progesterone inhibitor RU486 (mifepristone). RNA was isolated after 72h from both treated and untreated control cells. The experiment was repeated 3 times. Please note that slides were scanned three times successively (i.e. 3 .gpr files per sample) and the median raw values were used as input raw data for GeneSpring analysis (Median_Table_InputRAW.xlsx).

Project description:Progesterone (P4) acting through its cognate receptor, the progesterone receptor (PR), plays an important role in uterine physiology. The PR knockout (PRKO) mouse has demonstrated the importance of the P4-PR axis in the regulation of uterine function. To define the molecular pathways regulated by P4-PR in the mouse uterus, Affymetrix MG U74Av2 oligonucleotide arrays were used to identify alterations in gene expression after acute and chronic P4 treatments. In the analysis, retinoic acid metabolic genes, cytochrome P 450 26a1 (Cyp26a1), alcohol dehydrogenase 5, and aldehyde dehydrogenase 1a1 (Aldh1a1); kallikrein genes, Klk5 and Klk6; and specific transcription factors, GATA-2 and Cited2 [cAMP-corticosterone-binding protein/p300-interacting transactivator with glutamic acid (E) and aspartic acid (D)-rich tail], were validated as regulated by the P4-PR axis. Identification and analysis of these responsive genes will help define the role of PR in regulating uterine biology. Ovariectomized wild-type and progesterone receptor knockout mice were injected with either vehicle or 1 mg/mouse progesterone. The injections were repeated every 12 h, and groups of mice were killed 4 h after the first injection (acute P4 treatment) or 4 h after the fourth injection (chronic P4 treatment).

Project description:Follicle assembly is the process by which groups or ‘nests’ of oocytes break down to form primordial follicles. The size of the primordial follicle pool is the major determinant of the reproductive lifespan of a female. Previously, progesterone (P4) has been shown to inhibit follicle assembly, while tumor necrosis factor alpha (TNF-alpha) has been shown to promote the apoptosis that is necessary for follicle assembly. The current study examines how TNF-alpha and progesterone interact to regulate primordial follicle assembly. Ovaries were collected from newborn rats and placed in organ culture to examine the actions of P4 and TNF-alpha. P4 was found to decrease primordial follicle assembly and increase the percentage of un-assembled oocytes both in vitro and in vivo. TNF-alpha treatment did not change the proportion of assembled follicles in cultured ovaries, but did block the ability of P4 to inhibit follicle assembly. Microarray analysis of the ovarian transcriptome revealed that progesterone treatment of the ovaries altered the expression of 513 genes with 132 only expressed after P4 treatment and 16 only expressed in control ovaries. The majority of genes were up-regulated greater than 2-fold over control, with a small subset of 16 genes down-regulated. Categories of genes affected by P4 are described including a group of extra-cellular signaling factors. The progesterone receptors expressed at the time of follicle assembly included the surface membrane progesterone receptors PGRMC1, PGRMC2 and RDA288. The nuclear genomic P4 receptor was not expressed at appreciable levels. Progesterone increased the expression of several genes (TANK, NFkappaB, Bcl2l1 and Bcl2l2) involved in a signaling pathway that promotes cell survival and inhibits apoptosis. Observations indicate that P4 acts through the surface membrane progesterone receptors to regulate primordial follicle assembly, and that TNF-alpha can over-ride the inhibitory actions of P4 on follicle assembly. A major mechanism involved in the actions of P4 is an increase in cell survival genes and inhibition of the apoptosis pathway. Observations provide insight into the hormonal regulation of primordial follicle assembly and lead to novel approaches to potentially manipulate follicle assembly and reproductive capacity.

Project description:Progesterone (P4) acts via the endometrium to modify the uterine environment and promotes conceptus growth for elongation and pregnancy establishment. Ewes were ovariectomized and treated with P4 for 14 days or P4 for 14 days and RU486, a progesterone receptor antagonist, from days 8 to 14. Interrogation of the endometrial transcriptome resulted in 1,611 differentially abundant transcripts with 931 increased and 680 decreased in P4 as compared to P4+RU treated ewes.

Project description:The oviducts play a critical role in gamete and embryo transport, as well as supporting fertilization and early embryo development. Progesterone receptor (PGR) is a transcription factor highly expressed in oviductal cells, while it’s activating ligand, progesterone (P4), surges to peak levels as ovulation approaches. P4 is known to regulate oviduct cilia beating and muscular contractions in vitro, but how PGR may mediate this in vivo is poorly understood. We used PGR-knockout (PRKO) mice to determine how PGR regulates oviductal function during the periovulatory period, in particular oviductal transport and embryo support. We used microarrays to identify putative PGR-regulated genes in the oviduct during the periovulatory period, a time when the oviduct is preparing to receive the newly-ovulated COC.
