The dorsomedial portion of the nucleus tractus solitarius (dmNTS) is the site of termination of baroreceptor and cardiorespiratory vagal afferents and plays a critical role in cardiovascular regulation. Angiotensin II (Ang II) is a powerful signaling molecule in dmNTS neurons and exerts some of its biological effects by modulating Ca currents via reactive(More)
NADPH oxidase-generated superoxide can modulate crucial intracellular signaling cascades in neurons of the nucleus tractus solitarius (NTS), a brain region that plays an important role in cardiovascular processes. Modulation of NTS signaling by superoxide may be linked to the subcellular location of the mobile NADPH oxidase p47(phox) subunit, which is known(More)
Angiogenesis is a tightly regulated process, both during development and adult life. Animal models with mutations in the genes coding for placental growth factor (PlGF), a member of vascular endothelial growth factor (VEGF) family, or the tyrosine kinase domain of the PlGF receptor (Flt-1) have revealed differences between normal physiological angiogenesis(More)

Members of the platelet-derived growth factor/vascular endothelial growth factor (PDGF/VEGF) family have been implicated in a variety of functions in vertebrates, especially angiogenesis. Here we identify and characterize a PDGF/VEGF-like factor (named PVF-1) from the nematode C. elegans. We show that PVF-1 has biochemical properties similar to vertebrate(More)
Superoxide produced by the enzyme nicotinamide adenine dinucleotide phosphate (NADPH) oxidase mediates crucial intracellular signaling cascades in the medial nucleus of the solitary tract (mNTS), a brain region populated by catecholaminergic neurons, as well as astroglia that play an important role in autonomic function. The mechanisms mediating NADPH(More)
INTRODUCTION Netrins and semaphorins were discovered as axon guidance cues that instruct the direction of cell movement and axon extension by forming an extracellular gradient that provides polarity information to the migrating cell or axon growth cone. For example, UNC-6 (netrin) is expressed ventrally in C. elegans and is graded along the D/V axis of the(More)
Graded distributions of netrin and semaphorin guidance cues convey instructive polarity information to migrating cells and growth cones, but also have permissive (i.e. non-polarity determining) functions in mammalian development and repair. The permissive functions of these cues are largely uncharacterised at a molecular level. We found previously that(More)
The t(11;14)(q13;q32) is a hallmark of mantle cell lymphoma. It has been found less frequently in other lymphoproliferative disorders, such as B-prolymphocytic leukemia, plasma cell leukemia, chronic lymphocytic leukemia, and multiple myeloma. Here, we describe a patient with acute myeloid leukemia (AML), categorized as M5b according to(More)
