Abstract
The corpus luteum is the major source of progesterone, the essential hormone for female reproductive function. While progesterone activity has been the subject of extensive research for decades, characterization of non-canonical progesterone receptor/signaling pathways provided a new perspective for understanding the complex signal transduction mechanisms exploited by the progesterone hormone. Deciphering these mechanisms has significant implications in the management of luteal phase disorders and early pregnancy complications. The purpose of this review is to highlight the complex mechanisms through which progesterone-induced signaling mediates luteal granulosa cell activity in the corpus luteum. Here, we review the literature and discuss the up-to-date evidence on how paracrine and autocrine effects of progesterone regulate luteal steroidogenic activity. We also review the limitations of the published data and highlight future research priorities.

Abstract
Danggui Shaoyao San (DSS), a famous prescription, has been clinically proved to be effective in treating primary dysmenorrhea (PD). Currently there is no valid quality control data available for DSS. The main aim of the current research was to explore quality markers (Q-markers) of DSS. The chemical constituents of DSS were qualitatively identified using ultra-performance liquid chromatography tandem quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS) technology. On this basis, the targets of DSS and PD were predicted and screened using the TCMSP, SwissTargetPrediction, GeneCards, OMIM and TTD databases. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis was performed on the core intersection targets using string and Cytoscape 3.7.1 software. Then molecular docking was conducted to screen the Q-markers of DSS in PD. A total of 126 chemical constituents, including 22 organic acids, 14 phthalides, 24 monoterpenoids, five sesquiterpene lactones, 22 triterpenoids, four phenylpropanoids and 35 other compounds were preliminarily characterized. According to network pharmacology prediction analysis, six compounds containing polyporenic acid C, senkyunolide P, alisol B 23-acetate, naringenin, gallic acid, ferulic acid and albiflorin were regarded as Q-markers of DSS. The present research established an integrative UPLC-Q-TOF-MS and network pharmacology method to discover the latent Q-markers of DSS and provided a theoretical data for the follow-up quality control of DSS.

Abstract
OBJECTIVES The aim of this study was to evaluate two-dimensional and Doppler ultrasonographic changes of the ovary and uterus during estrus and the early post-estrus period in domestic cats. METHODS Two-dimensional and Doppler ultrasonographic evaluations of the ovaries and uterus were performed in seven queens on days 1, 3 and 5 of estrus, and 5 days after estrus (AE5). RESULTS On day 1, 5.4 ± 0.5 follicles of 2.1 ± 0.1 mm were detected progressively increasing in number and size up to day 5 and then decreased on AE5 (P <0.05). A maximum follicular diameter of 4.1 ± 0.1 mm was achieved on day 5. Both during and after estrus, the uterus was generally hypoechoic compared with the surrounding tissues and delineated by a thin hyperechoic line corresponding to the serosa. In some animals, the uterine layers were distinguished during and after estrus. The blood flow waveforms of the intraovarian and uterine arteries were characterized by a systolic peak and diastolic flow extending throughout the remainder of the cardiac cycle to the next systole. In the uterine artery waveforms, the early diastolic notch was mild or absent during most estrous observations. The resistance index of the intraovarian arteries decreased up to day 5, and then increased on AE5 (P <0.05). The resistance index of the uterine arteries was lower during estrus than in the post-estrus period (P <0.05). CONCLUSIONS AND RELEVANCE It is concluded that in the domestic cat, follicular number and diameter as well as ovarian and uterine blood flow changed during and immediately after estrus. Doppler ultrasound proved suitable to evaluate the hemodynamic changes involved in the cyclic remodeling of ovarian and uterine tissues that occurs during and after follicular growth in domestic cats.

Upregulation of miR-33 Exacerbates Heat-Stress-Induced Apoptosis in Granulosa Cell and Follicular Atresia of Nile Tilapia (Oreochromis niloticus) by Targeting TGFβ1I1. Genes (Basel) 2022; 13:genes13061009. [PMID: 35741771 PMCID: PMC9222912 DOI: 10.3390/genes13061009] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2022] [Revised: 05/18/2022] [Accepted: 05/23/2022] [Indexed: 02/04/2023] Open
Abstract
High temperature affects egg quality and increases follicular atresia in teleosts. The present study aimed to explore the regulated mechanism of ovary syndrome of Nile tilapia (Oreochromis niloticus) exposed to heat stress. To this end, we conducted histological and biochemical analyses and integrated miRNA-target gene analyses. The histochemical analyses confirmed that heat stress promoted the apoptosis of granulosa cell and therefore resulted in increased follicular atresia in the ovary. Heat stress led to the differential expression of multiple miRNAs (miR-27e, -27b-3p, -33, -34a -133a-5p, and -301b-5p). In a luciferase activity assay, miR-33 bound to the 3′-untranslated region (UTR) of the TGFβ1I1 (transforming growth factor-β1-induced transcript 1) gene and inhibited its expression. A TGFβ1I1 gene signal was detected in the granulosa cells of Nile tilapia by immunohistochemical analysis. Up-regulation of the miR-33 of tilapia at 6 d and 12 d exposed to heat (34.5 °C ± 0.5 °C) had significant down-regulation of the TGFβ1I1 expression of the gene and protein in tilapia ovaries. An miRNA-target gene integrated analysis revealed that miR-33 and TGFβ1I1 function in an apoptosis-related signal pathway. The signal transduction of the vascular endothelial growth factor (VEGF) family members VEGFA and its receptor (KDR) in the heat-stressed group decreased significantly compared with the control group. Transcript-levels of the Bax and Caspase-3 as apoptotic promotors were activated and Bcl-2 and Caspase-8 as apoptotic inhibitors were suppressed in the heat-stressed tilapia. These results suggest that heat stress increases the expression of miR-33, which targets TGFβ1I1 and inhibits its expression, resulting in decreased levels of follicle-stimulating hormone and 17β-estradiol and increased apoptosis by suppressing VEGF signaling, eventually inducing follicular atresia. In conclusion, our results show that the miR-33/TGFβ1I1 axis of Nile tilapia is involved in the follicular development of broodstock, and can suppress VEGF signaling to accelerate follicular atresia. Our findings demonstrate the suppressive role of miR-33 during oocyte development in Nile tilapia.

Abstract
During early embryonic development, late fetal growth, puberty, adult reproductive years, and advanced aging, bovine and human ovaries closely share molecular pathways and hormonal signaling mechanisms. Other similarities between these species include the size of ovaries, length of gestation, ovarian follicular and luteal dynamics, and pathophysiology of ovarian diseases. As an economically important agriculture species, cattle are a foundational species in fertility research with decades of groundwork using physiologic, genetic, and therapeutic experimental techniques. Many technologies used in modern reproductive medicine, such as ovulation induction using hormonal therapy, were first used in cows before human trials. Human ovarian diseases with naturally occurring bovine correlates include premature ovary insufficiency (POI), polycystic ovarian syndrome (PCOS), and sex-cord stromal tumors (SCSTs). This article presents an overview of bovine ovary research related to causes of infertility, ovarian diseases, diagnostics, and therapeutics, emphasizing where the bovine model can offer advantages over other lab animals for translational applications.

Abstract
Ovarian sex steroids can modulate new vessel formation and development, and the clarification of the underlying mechanism will provide insight into neovascularization-related physiological changes and pathological conditions. Unlike estrogen, which mainly promotes neovascularization through activating classic post-receptor signaling pathways, progesterone (P4) regulates a variety of downstream factors with angiogenic or antiangiogenic effects, exerting various influences on neovascularization. Furthermore, diverse progestins, the synthetic progesterone receptor (PR) agonists structurally related to P4, have been used in numerous studies, which could contribute to unequal actions. As a result, there have been many conflicting observations in the past, making it difficult for researchers to define the exact role of progestogens (PR agonists including naturally occurring P4 and synthetic progestins). This review summarizes available evidence for progestogen-mediated neovascularization under physiological and pathological circumstances, and attempts to elaborate their functional characteristics and regulatory patterns from a comprehensive perspective.

Abstract
This review resulted from an international workshop and presents a consensus view of critical advances over the past decade in our understanding of follicle function in ruminants. The major concepts covered include: (1) the value of major genes; (2) the dynamics of fetal ovarian development and its sensitivity to nutritional and environmental influences; (3) the concept of an ovarian follicle reserve, aligned with the rise of anti-Müllerian hormone as a controller of ovarian processes; (4) renewed recognition of the diverse and important roles of theca cells; (5) the importance of follicular fluid as a microenvironment that determines oocyte quality; (6) the 'adipokinome' as a key concept linking metabolic inputs with follicle development; and (7) the contribution of follicle development to the success of conception. These concepts are important because, in sheep and cattle, ovulation rate is tightly regulated and, as the primary determinant of litter size, it is a major component of reproductive efficiency and therefore productivity. Nowadays, reproductive efficiency is also a target for improving the 'methane efficiency' of livestock enterprises, increasing the need to understand the processes of ovarian development and folliculogenesis, while avoiding detrimental trade-offs as greater performance is sought.

Abstract
Little is known about the hormonal regulation of feline ovarian granulosa cell proliferation and steroidogenesis. The present study aimed to develop a hormone responsive granulosa cell culture system to measure steroidogenic and cell proliferation responses to help identify factors that might regulate ovarian function in queens. Five experiments were conducted each with 75 or more ovaries, three in spring and two in fall seasons. Granulosa cells were isolated and treated in vitro with various hormones in serum-free medium for 48 h after an initial 48 h plating in 10% fetal calf serum. In granulosa cells isolated from spring and fall collected feline ovaries, IGF1 alone and combined with FSH stimulated (P < 0.05) cell proliferation, whereas FSH alone had no effect (P > 0.10) on cell proliferation. Also, in granulosa cells collected in spring and fall, IGF1 alone and FSH alone increased (P < 0.05) estradiol production by severalfold, and a combination of FSH and IGF1 increased (P < 0.05) estradiol production above either FSH or IGF1 treatment alone. The FSH plus IGF1 treatment increased (P < 0.05) CYP19A1 mRNA abundance by 27-fold. In contrast, EGF decreased (P < 0.05) FSH plus IGF1-induced estradiol production by over 80% in granulosa cells of both spring and fall collected ovaries. In granulosa cells isolated from spring and fall collected ovaries, IGF1 plus FSH inhibited (P < 0.05) progesterone production. Melatonin increased (P < 0.05) FSH plus IGF1-induced cell proliferation and amplified (P < 0.05) the FSH plus IGF1-induced inhibition of progesterone production. However, melatonin and GH had no effect (P > 0.10) on estradiol production either alone or in combination with FSH plus IGF1 in both spring and fall. Prolactin, FGF9 and activin had no effect (P > 0.10) on cell proliferation or steroidogenesis. FGF2 decreased (P < 0.05) estradiol production without affecting progesterone production or cell numbers. Growth differentiation factor 9 (GDF9) increased (P < 0.05) progesterone production but had no effect (P > 0.10) on granulosa cell proliferation or estradiol production. In conclusion, the in vitro system described herewithin may be useful to assess and evaluate ovarian function in feline species and has identified EGF, FSH and IGF1 as major regulators of feline ovarian follicular function.

Abstract
Functional and enduring mammary structure is pivotal for producer profitability, and animal health and welfare in beef production. Genetic evaluations for teat and udder score in Canadian Angus cattle have previously been developed. The aim of this study was to identify genomic regions associated with teat and udder structure in Canadian Angus cows thereby enhancing knowledge of the biological architecture of these traits. Thus, we performed a weighted single-step genome wide association study (WssGWAS) to identify candidate genes for teat and udder score in 1,582 Canadian Angus cows typed with the GeneSeek® Genomic Profiler Bovine 130K SNP array. Genomically enhanced estimated breeding values (GEBVs) were converted to SNP marker effects using unequal variances for markers to calculate weights for each SNP over three iterations. At the genome wide level, we detected windows of 20 consecutive SNPs that explained more than 0.5% of the variance observed in these traits. A total of 35 and 28 windows were identified for teat and udder score, respectively, with two SNP windows in common for both traits. Using Ensembl, the SNP windows were used to search for candidate genes and quantitative trait loci (QTL). A total of 94 and 71 characterized genes were identified in the regions for teat and udder score, respectively. Of these, 7 genes were common for both traits. Gene network and enrichment analysis, using Ingenuity Pathway Analysis (IPA), signified key pathways unique to each trait. Genes of interest were associated with immune response and wound healing, adipose tissue development and morphology, and epithelial and vascular development and morphology. Genetic architecture from this GWAS confirms that teat and udder score are distinct, polygenic traits involving varying and complex biological pathways, and that genetic selection for improved teat and udder score is possible.

Abstract
Ubiquitin-like with plant homeodomain and really interesting new gene finger domains 1 (UHRF1) is a multi-domain nuclear protein that plays an important role in epigenetics and tumorigenesis, but its role in normal ovarian follicle development remains unknown. Thus, the present study evaluated if UHRF1 mRNA abundance in bovine follicular cells is developmentally and hormonally regulated, and if changes in UHRF1 are associated with changes in DNA methylation in follicular cells. Abundance of UHRF1 mRNA was greater in granulosa cells (GC) and theca cells (TC) from small (<6 mm) than large (≥8 mm) follicles and was greater in small-follicle GC than TC. In GC and TC, fibroblast growth factor 9 (FGF9) treatment increased (P < 0.05) UHRF1 expression by 2-fold. Also, luteinizing hormone (LH) and insulin-like growth factor 1 (IGF1) increased (P < 0.05) UHRF1 expression in TC by 2-fold, and forskolin (an adenylate cyclase inducer) alone or combined with IGF1 increased (P < 0.05) UHRF1 expression by 3-fold. An E2F transcription factor inhibitor (E2Fi) decreased (P < 0.05) UHRF1 expression by 44% in TC and by 99% in GC. Estradiol, progesterone, and dibutyryl-cAMP decreased (P < 0.05) UHRF1 mRNA abundance in GC. Treatment of GC with follicle-stimulating hormone (FSH) alone had no effect but when combined with IGF1 enhanced the UHRF1 mRNA abundance by 2.7-fold. Beauvericin (a mycotoxin) completely inhibited the FSH plus IGF1-induced UHRF1 expression in small-follicle GC. Treatments that increased UHRF1 mRNA (i.e., FGF9) in GC tended to decrease (by 63%; P < 0.10) global DNA methylation, and those that decreased UHRF1 mRNA (i.e., E2Fi) in GC tended to increase (by 2.4-fold; P < 0.10) global DNA methylation. Collectively, these results suggest that UHRF1 expression in both GC and TC is developmentally and hormonally regulated, and that UHRF1 may play a role in follicular growth and development as well as be involved in ovarian epigenetic processes.

Abstract
The E2F family of transcription factors plays an important role in the control of the cell cycle, cell proliferation, and differentiation, and their role in ovarian function is just emerging. Although some evidence suggests a possible role of E2F1 in ovarian follicular development, what regulates its production in ovarian cells is unknown. Objectives of this study were to determine whether: (i) E2F1 gene expression in granulosa cells (GCs) and theca cells (TCs) change with follicular development and (ii) E2F1 mRNA abundance in TC and GC is hormonally regulated. Using real-time PCR, E2F1 mRNA abundance in GC was 5.5-fold greater (P < 0.05) in small (SM; 1 to 5 mm) than large (LG; >8 mm) follicles, but in TC, E2F1 expression did not differ among follicle sizes. SM-follicle GC had 2.1-fold greater (P < 0.05) E2F1 mRNA than TC. In SM-follicle GC, FGF9 induced a 7.6-fold increase in E2F1 mRNA abundance; however, FGF9 did not affect (P > 0.10) abundance of E2F1 mRNA in LG-follicle TC or GC. Follicle-stimulating hormone (FSH) had no effect (P > 0.10) on E2F1 gene expression in SM- or LG-follicle GC. SM-follicle GC were concomitantly treated with insulin-like growth factor 1 (30 ng/mL), FSH (30 ng/mL), and either 0 or 30 ng/mL of FGF9 with or without 50 µM of an E2F inhibitor (E2Fi; HLM0064741); FGF9 alone increased (P < 0.05) GC numbers, whereas E2Fi alone decreased (P < 0.05) GC numbers, and concomitant treatment of E2Fi with FGF9 blocked (P < 0.05) this stimulatory effect of FGF9. Estradiol production was inhibited (P < 0.05) by FGF9 alone and concomitant treatment of E2Fi with FGF9 attenuated (P < 0.05) this inhibitory effect of FGF9. SM-follicle GC treated with E2Fi decreased (P < 0.05) E2F1 mRNA abundance by 70%. Collectively, our studies show that GC E2F1 mRNA is developmentally and hormonally regulated in cattle. Inhibition of E2F1 reduced FGF9-induced GC proliferation and attenuated FGF9-inhibited estradiol production, indicating that E2F1 may be involved in follicular development in cattle.

Abstract
Overexpression of the transcription factor, E2F8, has been associated with ovarian cancer. Objectives of this study were to determine: 1) if E2F8 gene expression in granulosa cells (GC) and theca cells (TC) change with follicular development, and 2) if E2F8 mRNA abundance in TC and GC is hormonally regulated. Using real-time PCR, E2F8 mRNA abundance in GC and TC was greater (P < 0.05) in small than large follicles. FGF9 induced an increase (P < 0.05) in E2F8 mRNA abundance by 1.6- to 7-fold in large-follicle (8-20 mm) TC and GC as well as in small-follicle (1-5 mm) GC. Abundance of E2F8 mRNA in TC was increased (P < 0.05) with FGF2, FGF9 or VEGFA treatments alone in vitro, and concomitant treatment of VEGFA with FGF9 increased (P < 0.05) abundance of E2F8 mRNA above any of the singular treatments; BMP4, WNT3A and LH were without effect. IGF1 amplified the stimulatory effect of FGF9 on E2F8 mRNA abundance by 2.7-fold. Collectively, our studies show for the first time that follicular E2F8 is developmentally and hormonally regulated indicating that E2F8 may be involved in follicular development.
