Hu KL, Chang HM, Zhao HC, Yu Y, Li R, Qiao J. Potential roles for the kisspeptin/kisspeptin receptor system in implantation and placentation. Hum Reprod Update 2020; 25:326-343. [PMID: 30649364 PMCID: PMC6450039 DOI: 10.1093/humupd/dmy046] [Citation(s) in RCA: 58] [Impact Index Per Article: 14.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2018] [Revised: 10/19/2018] [Accepted: 12/09/2018] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Initially identified as suppressors of metastasis in various types of cancer, kisspeptins are a family of neuropeptides that are key regulators of the mammalian reproductive axis. Accumulating evidence has shown that kisspeptin is able to control both the pulsatile and surge GnRH release, playing fundamental roles in female reproduction, which include the secretion of gonadotropins, puberty onset, brain sex differentiation, ovulation and the metabolic regulation of fertility. Furthermore, recent studies have demonstrated the involvement of the kisspeptin system in the processes of implantation and placentation. This review summarizes the current knowledge of the pathophysiological role and utility of these local placental regulatory factors as potential biomarkers during the early human gestation. OBJECTIVE AND RATIONALE A successful pregnancy, from the initiation of embryo implantation to parturition, is a complex process that requires the orchestration of a series of events. This review aims to concisely summarize what is known about the role of the kisspeptin system in implantation, placentation, early human pregnancy and pregnancy-related disorders, and to develop strategies for predicting, diagnosing and treating these abnormalities. SEARCH METHODS Using the PubMed and Google Scholar databases, we performed comprehensive literature searches in the English language describing the advancement of kisspeptins and the kisspeptin receptor (KISS1R) in implantation, placentation and early pregnancy in humans, since its initial identification in 1996 and ending in July 2018. OUTCOMES Recent studies have shown the coordinated spatial and temporal expression patterns of kisspeptins and KISS1R during human pregnancy. The experimental data gathered recently suggest putative roles of kisspeptin signaling in the regulation of trophoblast invasion, embryo implantation, placentation and early pregnancy. Dysregulation of the kisspeptin system may negatively affect the processes of implantation as well as placentation. Clinical studies indicate that the circulating levels of kisspeptins or the expression levels of kisspeptin/KISS1R in the placental tissues may be used as potential diagnostic markers for women with miscarriage and gestational trophoblastic neoplasia. WIDER IMPLICATIONS Comprehensive research on the pathophysiological role of the kisspeptin/KISS1R system in implantation and placentation will provide a dynamic and powerful approach to understanding the processes of early pregnancy, with potential applications in observational and analytic screening as well as the diagnosis, prognosis and treatment of implantation failure and early pregnancy-related disorders.

Abstract
Kisspeptins are a family of neuropeptides that are critical for the puberty initiation and female fertility. Plasma or serum kisspeptin is mainly derived from the placenta during pregnancy and plasma kisspeptin levels significantly increase across pregnancy. Plasma kisspeptin levels could be used as a potential biomarker for the detection of miscarriage, pre-eclampsia, gestational trophoblastic neoplasia (GTN), and fetal development. Kisspeptin may also be involved in the process of parturition by stimulating oxytocin secretion during term pregnancy. This review discussed the potential use of kisspeptin as a marker across pregnancy and highlighted the unresolved problems in this area. Tweetable abstract: Plasma kisspeptin levels could be used as a potential biomarker across pregnancy.

Abstract
Kisspeptins are a family of neuropeptides that are essential for fertility. Recent experimental data suggest a putative role of kisspeptin signaling in the direct control of ovarian function. To explore the expression of KISS1 and KISS1 receptor (KISS1R) in human granulosa lutein cells and the potential role of KISS1/KISS1R system in the pathogenesis of polycystic ovary syndrome (PCOS), we measured the concentration of KISS1 in follicular fluid, the expression of KISS1 and KISS1R in granulosa lutein cells, and the circulating hormones. The expression levels of KISS1 and KISS1R were significantly upregulated in human granulosa lutein cells obtained from women with PCOS. The expression levels of KISS1 in human granulosa lutein cells highly correlated with those of KISS1R in non-PCOS patients, but not in patients with PCOS, most likely due to the divergent expression patterns in women with PCOS. Additionally, the expression levels of KISS1 highly correlated with the serum levels of anti-Müllerian hormone (AMH). The expression levels of KISS1 and KISS1R, as well as the follicular fluid levels of KISS1, were not significantly different between the pregnant and nonpregnant patients in both PCOS and non-PCOS groups. In conclusion, the increased expression of KISS1 and KISS1R in human granulosa lutein cells may contribute to the pathogenesis of PCOS. The expression levels of KISS1 highly correlated with the serum levels of AMH. The KISS1 and KISS1R system in the ovary may not have a remarkable role in predicting the in vitro fertilization (IVF) outcome.

Abstract
Kisspeptins are a family of neuropeptides that are critical for initiating puberty and regulating ovulation in sexually mature females via the central control of the hypothalamic-pituitary-gonadal axis. Recent studies have shown that kisspeptin and its receptor kisspeptin receptor (KISS1R) are expressed in the mammalian ovary. Convincing evidence indicates that kisspeptins can activate a wide variety of signals via its binding to KISS1R. Experimental data gathered recently suggest a putative role of kisspeptin signaling in the direct control of ovarian function, including follicular development, oocyte maturation, steroidogenesis, and ovulation. Dysregulation or naturally occurring mutations of the kisspeptin/KISS1R system may negatively affect the ovarian function, leading to reproductive pathology or female infertility. A comprehensive understanding of the expression, actions, and underlying molecular mechanisms of this system in the human ovary is essential for novel approaches to therapeutic and diagnostic interventions in reproductive diseases and infertility.
