TLR4 Modulates Senescence and Paracrine Action in Placental Mesenchymal Stem Cells via Inhibiting Hedgehog Signaling Pathway in Preeclampsia.

Oxid Med Cell Longev 2022 14;2022:7202837. Epub 2022 Jun 14.

Department of Obstetrics and Gynecology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.

Preeclampsia (PE) is a heterogeneous disease closely associated with the accelerated senescence of the placentas. Placental mesenchymal stem cells (PMSCs) modulate placental development, which is abnormally senescent in PE together with abnormal paracrine. Both pivotal in the placenta development, Toll-like receptor 4 (TLR4) and Hedgehog (HH) pathway are also tightly involved in regulating cellular senescence. Read More

Kidney-placenta crosstalk in health and disease.

Clin Kidney J 2022 Jul 15;15(7):1284-1289. Epub 2022 Apr 15.

Physiology Department, Instituto Universitario del Hospital Italiano de Buenos Aires, Argentina.

Organ crosstalk allows the interaction between systems to adapt to a constant changing environment, maintaining homeostasis. The process of placentation and the new hormonal environment during pregnancy trigger physiological changes that modulate kidney function to control extracellular volume, acid-base balance and filtration of metabolic waste products. The bidirectional communication means that acute or chronic dysfunction of one organ can compromise the other. Read More

Department of Obstetrics and Gynecology, "Victor Babes" University of Medicine and Pharmacy Timisoara, 300041 Timisoara, Romania.

: Neonatal mortality is a global public health issue, disproportionately affecting low- and middle-income nations. Although Romania is a high-income nation, according to the European Union's most recent demographic data, it had the second-highest infant death rate in 2019. Although significant progress has been made in the last three decades in lowering newborn mortality, more initiatives to accelerate progress are required to meet the 2030 Sustainable Development Goals (SDG) objective.

The Role of Kisspeptin in the Pathogenesis of Pregnancy Complications: A Narrative Review.

Int J Mol Sci 2022 Jun 14;23(12). Epub 2022 Jun 14.

Department of Obstetrics and Perinatology, Medical University of Lublin, Jaczewskiego 8, 20-090 Lublin, Poland.

Kisspeptins are the family of neuropeptide products of the gene that exert the biological action by binding with the G-protein coupled receptor 54 (GPR54), also known as the KISS-1 receptor. The kisspeptin level dramatically increases during pregnancy, and the placenta is supposed to be its primary source. The role of kisspeptin has already been widely studied in hypogonadotropic hypogonadism, fertility, puberty disorders, and insulin resistance-related conditions, including type 2 diabetes mellitus, polycystic ovary syndrome, and obesity.

Primary Human Trophoblasts Mimic the Preeclampsia Phenotype after Acute Hypoxia-Reoxygenation Insult.

Cells 2022 06 11;11(12). Epub 2022 Jun 11.

Institute of Biochemistry and Molecular Medicine, Faculty of Medicine, University of Bern, 3012 Bern, Switzerland.

Preeclampsia (PE) is a pregnancy-specific disorder that affects 3 to 5% of pregnancies worldwide and is one of the leading causes of maternal and fetal morbidity and mortality. Nevertheless, how these events occur remains unclear. We hypothesized that the induction of hypoxic conditions in vitro in primary human trophoblast cells would mimic several characteristics of PE found in vivo. Read More

Stretch Causes Cell Stress and the Downregulation of Nrf2 in Primary Amnion Cells.

Biomolecules 2022 May 31;12(6). Epub 2022 May 31.

Anatomy, Biochemistry and Physiology, John A. Burns School of Medicine, University of Hawai'i at Mānoa, Honolulu, HI 96822, USA.

Nuclear-factor-E2-related factor 2 (Nrf2) is a key transcription factor for the regulation of cellular responses to cellular stress and inflammation, and its expression is significantly lower after spontaneous term labor in human fetal membranes. Pathological induction of inflammation can lead to adverse pregnancy outcomes such as pre-eclampsia, preterm labor, and fetal death. As stretch forces are known to act upon the fetal membranes in utero, we aimed to ascertain the effect of stretch on Nrf2 to increase our understanding of the role of this stimulus on cells of the amnion at term.

Comparative Characteristics of Sialoglycans Expression Disorders in the Placental Barrier Structures in Preeclampsia and Fetal Growth Restriction.

Bull Exp Biol Med 2022 Jun 24;173(2):270-275. Epub 2022 Jun 24.

V. I. Kulakov National Medical Research Center of Obstetrics, Gynecology, and Perinatology, Ministry of Health of the Russian Federation, Moscow, Russia.

We compared the expression profiles of α2,3- and α2,6-sialoglycans in the glycocalyx of the placental barrier structures in early and late forms of preeclampsia and fetal growth restriction using the method of lectin histochemistry. It was found that the expression of α2,3-sialoglycans in the syncytiotrophoblast and fetal endothelium of the terminal villi of the placenta was reduced in preeclampsia in comparison with normal placenta and, on the contrary, was increased in fetal growth restriction. Significant differences were found in both clinical phenotypes of preeclampsia and fetal growth restriction. Read More
