Abstract
BACKGROUND The pituitary belongs to the most important endocrine glands involved in regulating reproductive functions. The proper functioning of this gland ensures the undisturbed course of the oestrous cycle and affects the female's reproductive potential. It is believed that visfatin, a hormone belonging to the adipokine family, may regulate reproductive functions in response to the female's metabolic state. Herein we verified the hypothesis that suggests a modulatory effect of visfatin on the anterior pituitary transcriptome during the mid-luteal phase of the oestrous cycle. RESULTS RNA-seq analysis of the porcine anterior pituitary cells revealed changes in the expression of 202 genes (95 up-regulated and 107 down-regulated in the presence of visfatin, when compared to the non-treated controls), assigned to 318 gene ontology terms. We revealed changes in the frequency of alternative splicing events (235 cases), as well as long noncoding RNA expression (79 cases) in the presence of the adipokine. The identified genes were associated, among others, with reproductive system development, epithelial cell proliferation, positive regulation of cell development, gland morphogenesis and cell chemotaxis. CONCLUSIONS The obtained results indicate a modulatory influence of visfatin on the regulation of the porcine transcriptome and, in consequence, pituitary physiology during the mid-luteal phase of the oestrous cycle.

Am J Reprod Immunol 2020; 85:e13365. [PMID: 33099841 DOI: 10.1111/aji.13365] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 10/13/2020] [Accepted: 10/21/2020] [Indexed: 12/16/2022] Open
Abstract
PROBLEM The oviduct is essential for reproduction. We previously showed that oviduct epithelial cells (OECs) isolated from aged cows expressed higher levels of inflammatory cytokines, including interleukin (IL) 1A and IL1B. In addition, aging is associated with tissue dysfunction and cellular senescence via a senescence-associated secretory phenotype (SASP) and immune cell accumulation. We investigated whether IL1A or IL1B causes SASP production, cellular senescence, and inflammatory responses in bovine OECs. METHOD OF STUDY The OECs were isolated from bovine oviducts from young (mean 50.3 months) and aged cows (mean 157.0 months) and cultured. RESULTS Treatment with IL1A or IL1B induced SASP production (IL8, IL6, TNFA, and CCL2) and mRNA expression of cell adhesion molecules in bovine OECs, but both IL1s did not induce cellular senescence in OECs and migration of polymorphonuclear neutrophils (PMNs). Cultured medium of OECs treated with IL1s, especially IL1B, dramatically induced PMN migration. Treatment with the CCL2 inhibitor, but not IL8 or its receptor CXCR2 inhibitors, significantly reduced immune cell migration in IL1B-treated OEC-cultured medium. Treatment with IL1B increased PMN adhesion to OECs, resulting in further SASP production in OECs due to a PMN-OEC interaction. CONCLUSION We suggest that senescence-associated IL1s cause SASP production in bovine OECs and CCL2 induced by IL1B is essential for the migration of immune cells to OECs. Specifically, IL1B regulates PMN migration and adhesion to bovine OECs, and PMNs accelerate inflammatory cytokine production from bovine OECs via a direct interaction. These phenomena may contribute to chronic oviductal inflammation, resulting in subfertility.

Abstract
Studies on adipokines, substances that are produced in adipose tissue, indicate that they influence both metabolism and reproduction. Chemerin is a novel addition to the adipokine family. It is believed that chemerin receptors are expressed in different structures of the hypothalamic-pituitary-gonadal (HPG) axis, which are crucial for endocrine control of reproductive functions, including the pituitary. The aim of this study was to investigate the expression of chemerin receptors (CMKLR1, GPR1, CCRL2) genes and proteins in the porcine pituitary. The effect of chemerin on MAPK/Erk1/2, Akt and AMPK signalling pathways was also investigated. The anterior (AP) and posterior (PP) lobes of the pituitary were examined on days 2 to 3, 10 to 12, 14 to 16, and 17 to 19 of the oestrous cycle and on days 10 to 11, 12 to 13, 15 to 16, and 27 to 28 of pregnancy. This is the first study to demonstrate that CMKLR1, GPR1 and CCRL2 are expressed in the porcine AP and PP, which implies that this gland is sensitive to chemerin action. The expression of the studied chemerin receptors fluctuated during different phases of the cycle and early gestation, which could be related to changes in the endocrine status of female pigs. The study also revealed that CMKLR1 and CCRL2 proteins were present in gonadotrophs and thyrotrophs, whereas CCRL2 was also present in somatotrophs, during the cycle and early pregnancy. We observed that chemerin affected MAPK/Erk1/2, Akt and AMPK signalling pathways in the porcine AP. These results suggest that chemerin may participate in the regulation of reproductive functions at the level of the pituitary.

Abstract
Recent studies have demonstrated that chemerin participates in the regulation of female reproductive function at the level of the ovaries. Due to the lack of data concerning the presence of the chemerin system (chemerin and its receptors: CMKLR1, GPR1, CCRL2) in the ovaries of pigs, one of the most economically important livestock species, the aim of this study was to investigate the expression and localization of chemerin and its receptors in the ovaries of prepubertal and mature gilts. We also aimed to examine the concentrations of chemerin in the follicular fluid of prepubertal and mature animals. In the present study, we have demonstrated the expression patterns of chemerin system components in the porcine follicles of different sizes of prepubertal and mature animals, as well as in corpora lutea of mature gilts during the estrous cycle and early pregnancy. The obtained results suggest that the expression of chemerin system components is influenced by the reproductive stage, cell type, and the hormonal status of gilts (the estrous cycle/pregnancy). We have also presented the localization of the chemerin system components in various ovarian structures, and also showed changes in the concentration of chemerin in the follicular fluid of pigs. The presented findings not only confirm that chemerin is produced locally in the porcine ovary but they also demonstrate that chemerin directly affects ovarian cells, as confirmed by the presence of chemerin receptors in all ovarian structures. Therefore, chemerin appears to be an important intra-ovarian factor that could regulate ovary function in pigs.

Abstract
Adipokines such as chemerin affect metabolic status and reproductive function in many species. The hypothesis in the present study was that there were chemerin mRNA transcript and protein in the pituitary of pigs and that relative abundances fluctuate during the estrous cycle and early pregnancy. Chemerin is thought to modulate luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion during the estrous cycle. Changes in the relative abundance of chemerin mRNA transcript and protein in anterior (AP) and posterior (PP) pituitaries of pigs were investigated, for the first time in the present study, during four phases of the estrous cycle and four periods of early pregnancy. Chemerin protein was localized in gonadotrophs, thyrotrophs and somatotrophs during the estrous cycle and early gestation. Chemerin treatments affected both basal, GnRH- and/or insulin-induced LH and FSH production, with there being variations with phase of the estrous cycle when tissues were collected. These findings indicate chemerin may be produced locally in the pituitary and may affect female reproductive function by controlling the release of LH and FSH from AP cells.

Abstract
Chemerin (CHEM) may act as an important link integrating energy homeostasis and reproductive functions of females, and its actions are mediated by three receptors: chemokine-like receptor 1 (CMKLR1), G protein-coupled receptor 1 (GPR1), and C-C motif chemokine receptor-like 2 (CCRL2). The aim of the current study was to compare the expression of CHEM and its receptor (CHEM system) mRNAs (quantitative real-time PCR) and proteins (Western blotting and fluorescent immunohistochemistry) in the selected areas of the porcine hypothalamus responsible for gonadotropin-releasing hormone production and secretion: the mediobasal hypothalamus, preoptic area and stalk median eminence during the oestrous cycle and early pregnancy. Moreover, plasma CHEM concentrations were determined using ELISA. The expression of CHEM system has been demonstrated in the porcine hypothalamus throughout the luteal phase and follicular phase of the oestrous cycle, and during early pregnancy from days 10 to 28. Plasma CHEM levels and concentrations of transcripts and proteins of CHEM system components in the hypothalamus fluctuated throughout pregnancy and the oestrous cycle. Our study was the first experiment to demonstrate the presence of CHEM system mRNAs and proteins in the porcine hypothalamus and the correlations between the expression levels and physiological hormonal milieu related to the oestrous cycle and early pregnancy.

Abstract
The optimal environment in the oviduct is created by adjusting its ultrastructure and secretory capacity to protect gametes and embryos. It was hypothesized that direct contact between the isthmic epithelium and 2- and 4-cell-stage embryos would alter the transcriptomic profile of the isthmus in pigs. Microarray analysis was performed to determine the alterations in gene expression of the isthmus on Days 2-3 of pregnancy in pigs (after natural mating) during embryo presence in the oviduct. Of 43,803 microarray probes, 354 (0.81%) transcripts were altered (P-value ≤ 0.05 and fold-change ≥ 1.2) on the days of pregnancy when assessments were made. Of these 354 transcripts, 118 (33.3%) were up-regulated, and 236 (66.7%) were down-regulated. A total of 57 (48.3%) up-regulated and 73 down-regulated (30.9%) transcripts were classified into gene ontology categories. Of the 354 altered genes, 36 (10.2%) were categorized into the Toll-like or NOD-like receptor signaling pathway, in the immune system subcategory. Selected genes engaged in maternal immune function were down-regulated. The up-regulated genes were involved in epigenetic regulation, the protection of embryos against oxidative stress and xenobiotics and the control of estrogen metabolism. The 2- and 4-cell-stage embryos might, therefore, affect the oviductal transcriptome to optimize the intra-oviductal milieu, which is necessary to support proper development of embryos. The results of this study indicates the pig oviduct has the capacity to alter its transcriptomic profile as a result of early embryo development after natural mating.
