Abstract
Recurrent spontaneous abortion (RSA) is one of the most common complications during pregnancy and seriously affects women's physical and mental health. About 50% of RSA cases are of unknown etiology. Our previous study found that the decidual tissue of patients with unexplained recurrent spontaneous abortion (URSA) had low expression levels of serum and glucocorticoid-induced protein kinase (SGK) 1. Endometrial decidualization is a key link in the early stage of pregnancy and is crucial to the development and maintenance of pregnancy. Decidualization is the proliferation and differentiation of endometrial stromal cells into deciduals, which involves a complex physiological process such as ovarian steroid hormones (estrogen, progesterone, prolactin, etc.), growth factors, and intercellular signaling. The binding of estrogen and its receptor stimulates the synthesis of endometrial deciduating markers prolactin (PRL) and insulin-like growth factor binding protein 1 (IGFBP-1), which mediates the occurrence of decidualization. Among them, SGK1/ENaC is a signaling pathway closely related to decidualization. The purpose of this study was to further investigate the expression of SGK1 and decidualization-related molecules in the decidual tissue of URSA patients and to explore the potential mechanism of SGK1's protective effect in URSA patients and in mouse models. Decidual tissue samples from 30 URSA patients and 30 women who actively terminated pregnancy were collected, and a URSA mouse model was established and treated with dydrogesterone. Expression levels of SGK1 and its signaling pathway-related proteins (p-Nedd4-2, 14-3-3 protein and ENaC-a), estrogen and progesterone receptors (ERβ, PR), and decidualization markers (PRLR, IGFBP-1) were assessed. Our study found that SGK1, p-Nedd4-2, 14-3-3 proteins, and ENaC-a expression levels were reduced in the decidual tissue, the SGK1/ENaC signaling pathway was inhibited, and the expression levels of the decidualization markers PRLR and IGFBP-1 were downregulated in the URSA group compared with the controls. Additionally, the concentrations of E2, P, and PRL in the serum of mice were decreased in the URSA group compared with the controls. However, SGK1/ENaC pathway-related proteins, estrogen and progesterone and their receptors, and decidualization-related molecules were upregulated by dydrogesterone. These data suggest that estrogen and progesterone can induce decidualization by activating the SGK1/ENaC signaling pathway; disruption of this pathway can lead to the development of URSA. Dydrogesterone can increase the expression level of SGK1 protein in decidual tissue.

Abstract
Reproductive processes, in particular events that concern pregnancy, are fine-tuned to produce offspring. Reproductive success is of prime importance for the survival of every species. The highly conserved and ubiquitously expressed serum glucocorticoid-regulated kinase 1 (SGK1) was first implicated in infertility as a regulator of a Na+ channel. In this review, we emphasize the prominent role of SGK1 during early pregnancy: 1) balancing uterine luminal fluid secretion and reabsorption to aid blastocyst adhesion and to import nutrients and energy; 2) transducing signals from the blastocyst to the receptive endometrium; 3) inducing multiple genes that are involved in uterine receptivity and trophoblast invasion; 4) regulating cell differentiation and antioxidant defenses at the fetomaternal interface; and 5) contributing to the proliferation and survival of decidual stromal cells. Accordingly, SGK1 coordinates many cellular processes that are crucial to reproductive activities. Aberrant expression or function of SGK1 results in implantation failure and early pregnancy loss. Further investigation of the molecular mechanisms of the function of SGK1 might provide novel diagnostic tools and interventions for reproductive complications.-Lou, Y., Hu, M., Mao, L., Zheng, Y., Jin, F.

Small molecule inhibitor of type three secretion suppresses acute and chronic Chlamydia trachomatis infection in a novel urogenital Chlamydia model. BIOMED RESEARCH INTERNATIONAL 2015; 2015:484853. [PMID: 25695086 PMCID: PMC4324818 DOI: 10.1155/2015/484853] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/01/2014] [Accepted: 12/11/2014] [Indexed: 12/04/2022]
Abstract
Previously, we reported that a compound from a group of thiohydrazides of oxamic acids, CL-55, possessed antichlamydial activity in vitro that was accompanied by a decreased translocation of the type three secretion effector, IncA, into the host cell. In this study, the antichlamydial activity of CL-55 was tested in vivo in DBA/2 mice infected with C. trachomatis serovar D. We found that intravaginal inoculation of DBA/2 mice with the clinically relevant strain, C. trachomatis serovar D, results in a course of infection and pathology similar to that observed in humans. The early stage of infection in this model was characterized by a shedding of Chlamydia in vaginal secretions followed by an ascending infection and inflammation in the upper genital tract. We found that CL-55 possessed antibacterial activity in vivo and was able to control C. trachomatis vaginal shedding, ascending infection, and inflammation in the upper genital organs in DBA/2 mice. Our data provide a proof of concept for the protective effect of the thiadiazinon, CL-55, against chlamydial infection in vivo and support the feasibility of further studies of its potential therapeutic applications.
