The aim of this investigation was to evaluate the influence of a high-salt diet (HSD) on the effects of valsartan, an angiotensin II type 1 (AT(1)) receptor antagonist, on carotid arterial stiffness and structure in spontaneous hypertensive rats (SHR). Carotid arterial stiffness was studied in SHR receiving a HSD or a normal-salt diet (NSD) from the 10th to 20th week of age. Within each of the ...
The cDNAs for two separate human 17,B-hydroxysteroid dehydrogenases (17p-HSD) have been isolated and sequenced. The well-studied human placental cytosolic 17wBHSD (also referred to as estradiol dehydrogenase) preferentially catalyzes the reduction of estrone to estradiol-17/3 and the reduction of the C-20-ketone of progesterone to 20dihydroprogesterone. This isoform of the enzyme has been refer...
RATIONALE Glycogen synthase kinase (GSK)-3β upregulates cardiac genes in bone marrow-derived mesenchymal stem cells (MSCs) in vitro. Ex vivo modification of signaling mechanisms in MSCs may improve the efficiency of cardiac cell-based therapy (CBT). OBJECTIVE To test the effect of GSK-3β on the efficiency of CBT with MSCs after myocardial infarction (MI). METHODS AND RESULTS MSCs overexpres...
Glycogen synthase kinase 3β (GSK-3β) protein is a key regulator of neurogenesis, neuronal differentiation and polarisation during neurodevelopment. Sensory neurons in dorsal root ganglion (DRG) undergo a series of development stages during its maturation. In this study, we investigated the dynamic changes in GSK-3β expression and phosphorylation of its N-terminal serine-9 residue (p-GSK-3β (S9)...
Um novo triterpeno, 3β,22ξ,23ξ-triidróxi-22ξ-acetóxi-24-metil-lanosta-8,24(28)-dieno-31-al, denominado pisosteral, e quatro triterpenos lanostanos conhecidos, 3β,22ξ,23ξ-triidróxi-22ξ-acetóxi24-metil-lanosta-8,24(28)-dieno (pisosterol), 3α,22ξ,23ξ-triidróxi-22ξ-acetóxi-24-metil-lanosta8,24(28)-dieno (3-epi-pisosterol), 3β,22ξ,23ξ-triidróxi-23ξ-acetóxi-24-metil-lanosta-8,24(28)-dieno e 3β,22ξ,23...
The present study examined the hypothesis that hypertonic saline dextran (HSD), given after an initial insult, attenuates exaggerated inflammation that occurs with a second insult. Adult rats (n = 15 per group) were divided into groups 1 (sham burn), 2 [40% total body surface area burn + 4 ml/kg isotonic saline (IS) + 4 ml.kg(-1).% burn(-1) lactated Ringer solution (LR)], and 3 (burn + 4 ml/kg ...
We have investigated the expression of cholesterol side-chain cleavage cytochrome P450 (P450scc) and 3âhydroxysteroid dehydrogenase (3â-HSD) type 1 genes during human trophoblast differentiation in culture and the modulation of their steady-state mRNA levels by steroids. During the first 24 to 48 h after plating, mononucleated cells aggregated, forming colonies. After 60 h in culture, cell diam...
The expression of the 17/3-hydroxysteroid dehydrogenase (17-HSD) gene in a series of human breast cancer cell lines was studied by Northern blot hybridization with a cDNA probe and by a time-resolved immunofluorometric assay using polyclonal antibodies against the enzyme pro tein. The 17-HSD enzyme protein concentration was measured in the 800 x g cell extract. A high concentration was measured...
In C. elegans, steroid hormones function in conjunction with insulin/IGF-1-like signaling in promoting reproductive development over entry into the diapausal dauer stage. The NCR-1 and -2 (NPC1-related) intracellular cholesterol transporters function redundantly in preventing dauer arrest, presumably by regulating the availability of substrates for steroid hormone synthesis. We have identified ...
