Nephrotoxicity is a major side effect of cisplatin (CP)- and platinum-related chemotherapy, and inflammation contributes to disease pathogenesis. Interleukin-9 (IL-9) is a pleiotropic cytokine associated with inflammation. Here, we investigated the…

Using morpholino antisense oligonucleotide (MO) technology, we blocked leptin A or leptin receptor expression in embryonic zebrafish, and analyzed consequences of leptin A knock-down on fish development. Embryos injected with leptin A or leptin…

We previously reported a strain-related difference in basal 3 beta-hydroxysteroid dehydrogenase-isomerase (3 beta HSD) activity in response to testosterone in cultured Leydig cells. The data suggested that the response to testosterone was androgen…

Several serotonergic and adrenergic agents were tested for an ability to interact with mu, delta, and kappa opioid binding sites. Spiroxatrine interacted nearly equipotently with all three opioid subtypes, yielding K(i) values near 110 nM. A number…

Tamoxifen (10 pg/ml) was infused directly into superfused striatal tissue fragments of ovariectomized rats for a 50 min period. Immediately following the termination of tamoxifen there was a significant increase in dopamine output compared with…

Objective-The purpose of this study was to determine whether G-CSF promotes coronary collateral growth (CCG) and decipher the mechanism for this stimulation. Methods and Results-In a rat model of repetitive episodic myocardial ischemia (RI, 40…

Studies with the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) animal model of Parkinson's disease have shown the ability of 17 beta-estradiol to protect the nigrostriatal dopaminergic system. This paper reviews the signaling pathways mediating…

Mast cells (MCs) are important effector cells in asthma and pulmonary inflammation, and their proliferation and maturation is maintained by stem cell factor (SCF) via its receptor, c-Kit. Cysteinyl leukotrienes (cys-LTs) are potent inflammatory…

The sterol 12alpha-hydroxylase (CYP8B1) is a key enzyme of the bile acid biosynthetic pathway. It regulates the composition of bile acids in bile, i.e. ratio between cholic acid (CA) and chenodeoxycholic acid (CDCA). In similarity with cholesterol…

The positive chronotropic and inotropic effects of vasoactive intestinal peptide, VIP, were studied in an isolated canine right atrial preparation, Atria were removed, maintained in a bath, and perfused with Tyrode's solution. Contractile force and…

The timing of surgery during the menstrual cycle of premenopausal breast cancer patients was correlated with their disease-free survival (DFS) and overall survival (OS). The study included 150 premenopausal patients treated for breast cancer between…

Aldosterone plays a pathological role in cardiac fibrosis by directly affecting cardiac fibroblasts. Understanding of the cellular mechanisms of aldosterone action in cardiac fibroblasts, however, is rudimentary. One possibility is that aldosterone…

1 The neuropeptide substance P (SP) exerts an excitatory effect on sympathetic neurones by inhibiting a time- and voltage-dependent potassium current. During prolonged application of SP, the response desensitizes. The changes in kinetics of the SP…

To probe the binding of a peptide agonist to a G-protein coupled receptor in native membranes, the spin-labeled amino acid analogue 4-amino-4-carboxy-2,2,6,6-tetramethyl-piperidino-1-oxyl (TOAC) was substituted at either position 4 or 9 within the…

Human placental protein 14 (PP14; also known as glycodelin and progesterone-associatcd endometrial protein) is an immuno-suppressive protein of the lipocalin structural superfamily. Mechanisms regulating serum PP14's inmunosuppressive activity remain…

We report that stimulation inducing long-term potentiation (LTP) in the CA1 pyramidal cell layer of the hippocampus evokes significant increases in both BDNF and NT-3 mRNAs in CA1 neurons. No changes in BDNF or NT-3 mRNA levels were seen in the…

Rat alpha-1-macroglobulin (alpha(1)M) and alpha-2-macroglobulin (alpha(2)M) are murine homologs of human alpha(2)M, and rat alpha(2)M is generally known as an acute-phase protein. Monoamine-activated forms of human alpha(2)M have been shown to…

Transient receptor potential vanilliod 1 (TRPV1) channels have recently been postulated to play a role in the vascular complications/consequences associated with diabetes despite the fact that the mechanisms through which TRPV1 regulates vascular…

The proximal and distal growth plates of the principal long bones do not contribute equally to longitudinal growth. Most forelimb elongation occurs at the shoulder and wrist, while most hindlimb growth occurs at the knee. This study examined whether…
