The (pro)renin receptor ([P]RR) is a transmembrane protein that binds both renin and prorenin with high affinity, increasing the catalytic cleavage of angiotensinogen and signaling intracellularly through mitogen-activated protein kinase activation. Although initially reported as having no homology with any known membrane protein, other studies have(More)
In the Chx10-null ocular retardation (or(J)) mouse, retinal progenitor cell (RPC) proliferation is impaired, and bipolar neurons, a late born cell type, fail to differentiate. It is unclear whether Chx10 is required to maintain proliferation throughout retinogenesis or whether the bipolar cell defect is an indirect effect of growth arrest. We show that(More)
The regulation of the dopamine D1 receptor was investigated by using c-myc epitope-tagged D1 receptors expressed in Sf9 (fall armyworm ovary) cells. Treatment of D1 receptors with 10 microM dopamine for 15 min led to a loss of the dopamine-detected high-affinity state of the receptor accompanying a 40% reduction in the ability of the receptor to mediate(More)
Using subtractive hybridization screening, the methyl CpG-binding domain containing protein MBD3 was identified as being more prevalently expressed in the embryonic brain than in the adult. In this report, we present the mRNA and protein expression patterns of MBD3 in the developing brain. MBD3 expression was detected in neuroepithelial cells of the(More)
Rarefaction of the renal microvasculature correlates with declining kidney function. However, current technologies commonly used for its evaluation are limited by their reliance on endothelial cell antigen expression and assessment in two dimensions. We set out to establish a widely applicable and unbiased optical sectioning method to enable three(More)
AIM Our objective was to assess the effect of omega-3 polyunsaturated fatty acids (n-3 PUFAs) on atrial fibrillation (AF) vulnerability and atrial structure in a new model of atrial cardiomyopathy. METHODS AND RESULTS Dogs were studied in three groups: seven control dogs (UNPACED) and 24 dogs undergoing simultaneous atrioventricular pacing (for 2 weeks)(More)
Dopamine D2 receptor agonists are commonly used in the control of PRL-secreting adenomas, and the sensitivity of dopamine agonists during long term therapy is exquisite. However, the molecular mechanisms responsible for the maintenance of this cellular sensitivity to dopamine agonists remain poorly understood. In the present study, we examined the(More)
Confocal microscopy in association with three-dimensional reconstruction was used to examine the changes in the microtubules and microfilaments following cannabinoid treatment of PC12 cells. Microtubules and microfilaments were disrupted in a dose-dependent manner following treatment with 10-30 microM delta 9-tetrahydrocannabinol (THC). A disruption of(More)
Visualization of the complex lung microvasculature and resolution of its three-dimensional architecture remains a difficult experimental challenge. We present a novel fluorescent microscopy technique to visualize both the normal and diseased pulmonary microvasculature. Physiologically relevant pulmonary perfusion conditions were applied using a(More)
We present a novel animal model for post-transplant obliterative airway disease in which the donor trachea is implanted into the recipient's lung parenchyma. Although this procedure is technically more challenging than the heterotopic model of implantation into a subcutaneous pouch, it has several important advantages some of which are the appropriate local(More)
