Heart transplantation has evolved as the criterion standard therapy for end-stage heart failure, but its efficacy is limited by the development of cardiac allograft vasculopathy (CAV), a unique and rapidly progressive form of atherosclerosis in heart transplant recipients. Here, we briefly review the key processes in the development of CAV during heart transplantation and highlight the roles of transient receptor potential (TRP) channels in these processes during heart transplantation. Understanding the roles of TRP channels in contributing to the key procedures for the development of CAV during heart transplantation could provide basic scientific knowledge for the development of new preventive and therapeutic approaches to manage patients with CAV after heart transplantation...

Paradoxical observations have been made regarding the role of caveolin-1 (Cav-1) during cellular senescence. For example, caveolin-1 deficiency prevents reactive oxygen species-induced cellular senescence despite mitochondrial dysfunction, which leads to senescence. To resolve this paradox, we re-addressed the role of caveolin-1 in cellular senescence in human diploid fibroblasts, A549, HCT116, and Cav-1(-/-) mouse embryonic fibroblasts. Cav-1 deficiency (knockout or knockdown) induced cellular senescence via a p53-p21-dependent pathway, downregulating the expression level of the cardiolipin biosynthesis enzymes and then reducing the content of cardiolipin, a critical lipid for mitochondrial respiration...

Hippocampal synaptic plasticity comprises a key cellular mechanism for information storage. In the hippocampus, both long-term potentiation (LTP) and long-term depression (LTD) are triggered by synaptic Ca(2+) -elevations that are typically mediated by the opening of voltage-gated cation channels, such as N-methyl-D-aspartate receptors (NMDAR), in the postsynaptic density. The integrity of the post-synaptic density is ensured by the extracellular matrix (ECM). Here, we explored whether synaptic plasticity is affected in adult behaving mice that lack the ECM proteins brevican, neurocan, tenascin-C and tenascin-R (TG)...

Voltage-activated calcium (Cav) channels couple intracellular signaling pathways to membrane potential by providing Ca(2+) ions as second messengers at sufficiently high concentrations to modulate effector proteins located in the intimate vicinity of those channels. Here we show that protein kinase Cβ (PKCβ) and brain nitric oxide synthase (NOS1), both identified by proteomic analysis as constituents of the protein nano-environment of Cav2 channels in the brain, directly coassemble with Cav2.2 channels upon heterologous coexpression...

BACKGROUND: Loperamide is an anti-diarrheal drug prescribed for non-infectious diarrhea. The drug is an opioid receptor agonist, a blocker of voltage-dependent calcium channel (Cav) and a calmodulin (CaM) inhibitor on human cells. Loperamide has been reported to exert anti-amoebic effects against pathogenic strains of Acanthamoeba castellanii. OBJECTIVES: The precise mode of antibiotic action, cellular target homology with human counterparts and the pattern of cell death induced by loperamide in Acanthamoeba castellanii remain to be established...

Anthracyclines are chemotherapeutic drugs known to induce heart failure in a dose-dependent manner. Mechanisms involved in anthracycline cardiotoxicity are an area of relevant investigation. Caveolins bind, organize and regulate receptors and signaling molecules within cell membranes. Caveolin-3 (Cav-3), integrins and related membrane repair proteins can function as cardioprotective proteins. Expression of these proteins in anthracycline-induced heart failure has not been evaluated. We tested the hypothesis that daunorubicin alters cardioprotective protein expression in the heart...

In the lungs, endothelial nitric oxide synthase (eNOS) is usually expressed in endothelial cells and inducible nitric oxide synthase (iNOS) is mainly expressed in alveolar macrophages and epithelial cells. Both eNOS and iNOS are involved in lung inflammation. While they play several roles in lung inflammation formation and resolution, their expression and activity are also regulated by inflammatory factors. Their expression relationship in virus infection-induced lung injury is not well addressed. In this report, we analyzed expression of both eNOS and iNOS, the production of nitric oxide (NO) and reactive oxygen species (ROS), and expression of their associated regulatory proteins, heat shock protein 90 (HSP90) and caveolin-1 (Cav-1), in a swine lung injury model induced by porcine reproductive and respiratory syndrome virus (PRRSV) infection...

Hemorrhage is a common cause of death in the battlefield. Valproic acid (VPA) has been associated with improved outcomes in multiple models of trauma, when combined with isotonic fluid resuscitation. However, isotonic fluid administered in this setting is logistically impractical and may be associated with complications. In this study, we sought to evaluate the feasibility and immunologic impact of combining VPA treatment with low-volume hypertonic saline (HTS). In vivo: female Yorkshire swine were subjected to hemorrhage (40% total blood volume) and polytrauma (rib fracture and delayed liver injury)...

The abnormally hyperphosphorylated tau is thought to be implicated in diabetes-associated cognitive deficits. The role of mammalian target of rapamycin (mTOR) / S6 kinase (S6K) signalling in the formation of tau hyperphosphorylation has been previously studied. Caveolin-1 (Cav-1), the essential structure protein of caveolae, promotes neuronal survival and growth, and inhibits glucose metabolism. In this study, we aimed to investigate the role of Cav-1 in the formation of tau hyperphosphorylation under chronic hyperglycemic condition (HGC)...

AIMS: Oxidatively modified lipoproteins may promote the development/progression of calcific aortic valve stenosis (CAVS). Oxidative transformation of low-density lipoprotein (OxLDL) generates lysophosphatidic acid (LPA), a lipid mediator that accumulates in mineralized aortic valves. LPA activates at least 6 different G protein-coupled receptors, which may play a role in the pathophysiology of CAVS. We hypothesized that LPA derived from OxLDL may promote a NF-κB signature that drives osteogenesis in the aortic valve...

We report a case of the successful use of a central arteriovenous (cAV) coupler device to treat severe drug-resistant primary hypertension in a 46-year-old female. The device is inserted via a femoral approach to create an ateriovenous fistula between the external iliac artery and vein and has shown promise in the treatment of severe hypertension. The patient's 24-hr ambulatory blood pressure (ABP) pre device insertion on eleven anti-hypertensive medications revealed a mean 24-hr ABP of 165/98 mm Hg. The insertion of the cAV coupler resulted in a sustained anti-hypertensive effect nine months post-procedure, with mean 24-hr ABP of 154/91 mm Hg on only two anti-hypertensives...

BACKGROUND: Assessing the QT interval in donors is important to exclude long QT syndrome as the cause of death. A donor heart with a corrected QT (QTc)>500 msec is often concerning. We sought to evaluate first-year outcomes for donors with a QTc interval > 500 msec. METHODS: Between 2010 and 2014, we assessed 257 donor hearts for QTc interval > 500msec. Post-transplant outcomes included 1-year survival, 1-year freedom from any-treated rejection, 1- year freedom from CAV defined as stenosis ≥ 30% by angiography, and 1-year freedom from Non-Fatal Major Adverse Cardiac Events...

BACKGROUND: There is inadequate power to perform a valid clinical trial in pediatric heart transplantation (HT) using a conventional end-point, because the disease is rare and hard end-points, such as death or graft loss, are infrequent. We sought to develop and validate a surrogate end-point involving the cumulative burden of post-transplant complications to predict death/graft loss to power a randomized clinical trial of maintenance immunosuppression in pediatric HT. METHODS: Pediatric Heart Transplant Study (PHTS) data were used to identify all children who underwent an isolated orthotopic HT between 2005 and 2014 who survived to 6 months post-HT...

Studies in vitro and in vivo demonstrate that membrane/lipid rafts and caveolin (Cav) organize progrowth receptors, and, when overexpressed specifically in neurons, Cav-1 augments neuronal signaling and growth and improves cognitive function in adult and aged mice; however, whether neuronal Cav-1 overexpression can preserve motor and cognitive function in the brain trauma setting is unknown. Here, we generated a neuron-targeted Cav-1-overexpressing transgenic (Tg) mouse [synapsin-driven Cav-1 (SynCav1 Tg)] and subjected it to a controlled cortical impact model of brain trauma and measured biochemical, anatomic, and behavioral changes...
