BACKGROUND: We investigated the efficacy and mechanisms of tadalafil, a selective phosphodiesterase 5 inhibitor, in treating preeclampsia (PE) with fetal growth restriction (FGR) using L-NG-nitroarginine methyl ester (L-NAME)-induced PE with FGR in pregnant mice as our experimental model. METHODS: C57BL/6 mice were divided into 2 groups 11 days postcoitum (d.p.c.). A control group of dams (C dam) received 0.5% carboxymethylcellulose (CMC). A L-NAME-treated group received 1 mg/ml L-NAME dissolved in CMC...

BACKGROUND: A large number of studies have shown hypertension of offspring in adulthood is related to parental health during pregnancy. Hydrogen sulfide (H2S) could relax placental vasculature and improve intrauterine growth restriction. In the present study, we want to observe the effect of H2S on the fetal programming of renovascular hypertension, a rat model of secondary hypertension. METHODS: Renovascular hypertension was induced by 2-kidney-1-clip, their adult pups were used to evaluate basal blood pressure...

The mammalian kidney is a highly complex organ, composed of various cell types within a unique structural framework. Nonetheless, in recent years, giant leaps in our understanding of nephrogenesis and the origin of new cells in the adult kidney, have resulted in novel routes to regenerate damaged nephrons. While several strategies can be envisioned to achieve this aim, one common theme is the reliance on renal lineage cells, since extra-renal cells, such as bone-marrow derived cells, have been shown to be devoid of renal differentiation capacity...

BACKGROUND: Circular RNA (circRNA) is one type of noncoding RNA that forms a covalently closed continuous loop. Similar to long noncoding RNA (lncRNA), circRNA can act as microRNA (miRNA) 'sponges' to regulate gene expression, and its abnormal expression is related to diseases such as atherosclerosis, nervous system disorders and cancer. So far, there have been no systematic studies on circRNA abundance and expression profiles in human adult and fetal tissues. RESULTS: We explored circRNA expression profiles using RNA-seq data for six adult and fetal normal tissues (colon, heart, kidney, liver, lung, and stomach) and four gland normal tissues (adrenal gland, mammary gland, pancreas, and thyroid gland)...

Hypoxic environments at high altitude have significant effects on kidney injury. Following injury, renal primary cilia display length alterations. Primary cilia are mechanosensory organelles that regulate tubular architecture. The effect of hypoxia on cilia length is still controversial in cultured cells, and no corresponding in vivo study exists. Using fetal and adult sheep, we here study the effect of chronic hypobaric hypoxia on the renal injury, intracellular calcium signaling and the relationship between cilia length and cilia function...

Sulfate is an obligate nutrient for fetal growth and development. In mice, the renal Slc13a1 sulfate transporter maintains high maternal circulating levels of sulfate in pregnancy, and the placental Slc13a4 sulfate transporter mediates sulfate supply to the fetus. Both of these genes have been linked to severe embryonal defects and fetal loss in mice. However, the clinical significance of SLC13A1 and SLC13A4 in human gestation is unknown. One approach towards understanding the potential involvement of these genes in human fetal pathologies is to use an animal model, such as the pig, which mimics the developmental trajectory of the human fetus more closely than the previously studied mouse models...

We report the case of a malrotated right kidney associated with giant prenatal hydronephrosis due to a non vascular extrinsic ureteropelvic compression. The kidney presented an hyper-rotation of 180° in relation to the original fetal position, with the renal hilum backward looking. At neonatal surgery we discover that the inferior pole of the kidney pushes laterally the ureteropelvic junction like a violin bridge. The simple uncrossing of the ureteropelvic junction from the inferior renal pole relieves the extrinsic ureteral obstacle and the giant hydronephrosis...

BACKGROUND: IGF2 is a key determinant of fetal growth, and altered expression of IGF2 is implicated in fetal growth disorders and maternal metabolic derangements including gestational diabetes. Here we studied how increased levels of IGF2 in late pregnancy affect fetal growth. METHODS: We employed a rat model of repeated intra-fetal IGF2 administration in late pregnancy, i.e. during GD19-GD21, and measured the consequences on fetal organ weight and expression of insulin/IGF-axis components...

BACKGROUND: The mechanism of cholesteryl ester transfer protein (CETP) in lipid metabolism is still unclear. Furthermore, the relationship of CETP and atherosclerosis (AS) has been controversial. As pigs are a good model for both lipid and AS research, we investigated the lipid metabolism of human CETP (hCETP) transgenic pigs and explored the mechanism of CETP in lipid modulation. METHODS: Plasmids expressing the hCETP gene were designed, successfully constructed, and transfected into porcine fetal fibroblasts by liposomes...

Background: Cyclosporine A (CsA) is a commonly used clinical immunosuppressant. However, CsA exposure in rabbits during the gestation period was shown to cause a postnatal decrease in the number of nephrons, with the effects remaining unknown. In this study, we aimed to explore the effects of CsA on metanephros development in the pregnant BALB/c mice. Methods: Pregnant mice were randomly divided into two groups, and CsA (10 mg·kg(-1)·d(-1)) was subcutaneously injected from gestation day 10...

Chronic kidney disease (CKD) is a world-wide healthcare problem, resulting in increased cardiovascular mortality and often leading to end-stage kidney disease (ESKD) where patients require kidney replacement therapies such as hemodialysis or kidney transplantation. Loss of functional nephrons contributes to the progression of CKD, which can be attenuated but not reversed due to inability to generate new nephrons in human adult kidneys. Human pluripotent stem cells (hPSCs), by virtue of their unlimited self-renewal and ability to differentiate into cells of all three embryonic germ layers, are attractive sources for kidney regenerative therapies...

PURPOSE: Urinary tract infection (UTI) is defined as a common bacterial infection that can lead to significant morbidity such as stricture, fistula, abscess formation, bacteremia, sepsis, pyelonephritis, and kidney dysfunction with a mortality rates reported of 1% in men and 3% in women because of development of pyelonephritis. UTIs are more common in women and the 33% of them require antimicrobials treatment for at least one episode by the age of 24 years. UTIs are the most common infections observed during pregnancy and up to 30% of mothers with not treated asymptomatic bacteriuria may develop acute pyelonephritis which consequently can be associated to adverse maternal and fetal outcomes...

BMP7 is expressed in ureteric buds and cap mesenchyme of the fetal kidney, mediating branching morphogenesis and survival and priming of metanephric mesenchyme. Although dose-dependent effects of BMP7 in collecting duct cells have been reported, studies in metanephric mesenchymal cells are lacking. We examined the effects of BMP7 on MAP kinase activation, proliferation, and expression of cadherins in a metanephric mesenchymal cell line MS7 by thymidine incorporation, immunoblot analysis, and quantitative real-time PCR The levels of phosphorylated ERK (P-ERK) and phosphorylated p38 (P-p38) were not altered at 10 min, 1 h, and 6 h with low-dose BMP7 (0...

With the increasing prevalence of chronic kidney disease (CKD) worldwide, the number of pregnant women with various degrees of renal dysfunction is expected to increase. There is a bidirectional relation between CKD and pregnancy in which renal dysfunction negatively affects pregnancy outcomes, and the pregnancy can have a deleterious impact on various aspects of kidney disease. It has been shown that even mild renal dysfunction can increase considerably the risk of adverse maternal and fetal outcomes. Moreover, data suggest that a history of recovery from acute kidney injury is associated with adverse pregnancy outcomes...
