|Intraluminal Pressure Is a Stimulus for NFATc3 Nuclear Accumulation: ROLE OF CALCIUM, ENDOTHELIUM-DERIVED NITRIC OXIDE, AND cGMP-DEPENDENT PROTEIN KINASE||Blood Vessel|
The transcription factor NFAT (nuclear factor of activated T-cells) is implicated in cardiac hypertrophy and vasculogenesis. NFAT activation, reflecting dephosphorylation by the calcium-dependent phosphatase, calcineurin, and subsequent nuclear localization, is generally thought to require a sustained increase in intracellular calcium. However, in smooth muscle we have found that elevation of calcium by membrane depolarization fails to induce an increase in nuclear localization of the NFATc3 isoform. Here, we demonstrate that […]

|Myogenic tone, reactivity, and forced dilatation: a three-phase model of in vitro arterial myogenic behavior||Blood Vessel|
Myogenic behavior, prevalent in resistance arteries and arterioles, involves arterial constriction in response to intravascular pressure. This process is often studied in vitro by using cannulated, pressurized arterial segments from different regional circulations. We propose a comprehensive model for myogenicity that consists of three interrelated but dissociable phases: 1) the initial development of myogenic tone (MT), 2) myogenic reactivity to subsequent changes in pressure (MR), and 3) forced dilatation at […]

Phosphorylation of phospholamban at threonine-17 reduces cardiac adrenergic contractile responsiveness in chronic pressure overload-induced hypertrophy. Mills GD, Kubo H, Harris DM, Berretta RM, Piacentino V 3rd, Houser SR Abstract: Physiological hemodynamic stress, such as aerobic exercise, is intermittent and requires an increase in Ca2+-dependent contractility through sympathetic nervous system activation. Pathological hemodynamic stress, such as hypertension, is persistent and requires sustained increases in cardiac function. Over time, this causes left […]
|Overexpression of heat shock protein 27 protects against ischaemia/reperfusion-induced cardiac dysfunction via stabilization of troponin I and T.||Calcium and Contractility|
Overexpression of heat shock protein 27 protects against ischaemia/reperfusion-induced cardiac dysfunction via stabilization of troponin I and T. Lu XY, Chen L, Cai XL, Yang HT Abstract: Aims: Heat shock protein 27 (Hsp27) renders cardioprotection from ischaemia/reperfusion (I/R) injury, but little is known about its role in myofilaments. We proposed that increased expression of Hsp27 may improve post-ischaemic contractile dysfunction by preventing I/R-induced cardiac troponin I (cTnI) and troponin T […]
|Chronic inutero cyclooxygenase inhibition alters PGE2-regulated ductus arteriosuscontractile pathways and prevents postnatal closure.||Blood Vessel|
NOTE: In the ductus arteriosus of fetal mice: (this is one of the first papers to ever use pressurized myography to study the mouse ductus, and is particularly cool for studying premature fetal vessels). Although prostaglandin E2 (PGE2) vasodilates the ductus arteriosus, tocolysis with cyclooxygenase (COX) inhibitors delays postnatal ductus arteriosus closure. We used fetal mice and sheep to determine whether PGE2 has a role in the development of ductus […]
|High blood pressure arising from a defect in vascular function|
Hypertension, a major cardiovascular risk factor and cause of mortality worldwide, is thought to arise from primary renal abnormalities. However, the etiology of most cases of hypertension remains unexplained. Vascular tone, an important determinant of blood pressure, is regulated by nitric oxide, which causes vascular relaxation by increasing intracellular cGMP and activating cGMP-dependent protein kinase I (PKGI). Here we show that mice with a selective mutation in the N-terminal protein […]
|Sulfonylurea Receptor-Dependent and -Independent Pathways Mediate Vasodilation Induced by ATP-Sensitive K+ Channel Openers||Blood Vessel|
