Directing valvular interstitial cell myofibroblast-like differentiation in a hybrid hydrogel platform.
Hjortnaes J, Camci-Unal G, Hutcheson JD, Jung SM, Schoen FJ, Kluin J, Aikawa E, Khademhosseini A
Three dimensional (3D) hydrogel platforms are powerful tools, providing controllable, physiologically relevant microenvironments that could aid in understanding how various environmental factors direct valvular interstitial cell (VIC) phenotype. Continuous activation of VICs and their transformation from quiescent fibroblast to activated myofibroblast phenotype is considered to be an initiating event in the onset of valve disease. However, the relative contribution VIC phenotypes is poorly under...

Lundby A, Rossin EJ, Steffensen AB, Acha MR, Newton-Cheh C, Pfeufer A, Lynch SN, QT Interval International GWAS Consortium (QT-IGC), Olesen SP, Brunak S, Ellinor PT, Jukema JW, Trompet S, Ford I, Macfarlane PW, Krijthe BP, Hofman A, Uitterlinden AG, Stricker BH, Nathoe HM, Spiering W, Daly MJ, Asselbergs FW, van der Harst P, Milan DJ, de Bakker PI, Lage K, Olsen JV
Genome-wide association studies (GWAS) have identified thousands of loci associated with complex traits, but it is challenging to pinpoint causal genes in these loci and to exploit subtle association signals. We used tissue-specific quantitative interaction proteomics to map a network of five genes involved in the Mendelian disorder long QT syndrome (LQTS). We integrated the LQTS network with GWAS loci from the corresponding common complex trait, QT-interval variation, to identify candidate gene...

New insights on Carpentier I mitral regurgitation from multidetector row computed tomography.
van Rosendael PJ, Katsanos S, Kamperidis V, Roos CJ, Scholte AJ, Schalij MJ, Ajmone Marsan N, Bax JJ, Delgado V
The underlying mechanism of mitral regurgitation (MR) because of isolated annulus dilation (Carpentier type I) remains controversial in patients with atrial fibrillation (AF). The present study evaluated changes in mitral valve geometry of patients with AF and structurally and functionally normal left ventricles and mitral leaflets. Grade of MR and left ventricular (LV) function was evaluated with echocardiography. Changes in mitral valve geometry were evaluated with multidetector row computed t...

TLR4 accessory molecule RP105 (CD180) regulates monocyte-driven arteriogenesis in a murine hind limb ischemia model.
Bastiaansen AJ, Karper JC, Wezel A, de Boer HC, Welten SM, de Jong RC, Peters EA, de Vries MR, van Oeveren-Rietdijk AM, van Zonneveld AJ, Hamming JF, Nossent AY, Quax PH
Aims: We investigated the role of the TLR4-accessory molecule RP105 (CD180) in post-ischemic neovascularization, i.e. arteriogenesis and angiogenesis. TLR4-mediated activation of pro-inflammatory Ly6Chi monocytes is crucial for effective neovascularization. Immunohistochemical analyses revealed that RP105+ monocytes are present in the perivascular space of remodeling collateral arterioles. As RP105 inhibits TLR4 signaling, we hypothesized that RP105 deficiency would lead to an unrestrained TLR4-...

Murine cytomegalovirus virion-associated protein M45 mediates rapid NF-κB activation after infection.
Krause E, de Graaf M, Fliss PM, Dölken L, Brune W
Unlabelled: Murine cytomegalovirus (MCMV) rapidly induces activation of nuclear factor κB (NF-κB) upon infection of host cells. After a transient phase of activation, the MCMV M45 protein blocks all canonical NF-κB-activating pathways by inducing the degradation of the gamma subunit of the inhibitor of κB kinase complex (IKKγ; commonly referred to as the NF-κB essential modulator [NEMO]). Here we show that the viral M45 protein also mediates rapid NF-κB activation immediately after infection. MC...

Phytochemicals perturb membranes and promiscuously alter protein function.
Ingólfsson HI, Thakur P, Herold KF, Hobart EA, Ramsey NB, Periole X, de Jong DH, Zwama M, Yilmaz D, Hall K, Maretzky T, Hemmings HC, Blobel C, Marrink SJ, Koçer A, Sack JT, Andersen OS
A wide variety of phytochemicals are consumed for their perceived health benefits. Many of these phytochemicals have been found to alter numerous cell functions, but the mechanisms underlying their biological activity tend to be poorly understood. Phenolic phytochemicals are particularly promiscuous modifiers of membrane protein function, suggesting that some of their actions may be due to a common, membrane bilayer-mediated mechanism. To test whether bilayer perturbation may underlie this diver...

Tri-layered elastomeric scaffolds for engineering heart valve leaflets.
Masoumi N, Annabi N, Assmann A, Larson BL, Hjortnaes J, Alemdar N, Kharaziha M, Manning KB, Mayer JE, Khademhosseini A
Tissue engineered heart valves (TEHVs) that can grow and remodel have the potential to serve as permanent replacements of the current non-viable prosthetic valves particularly for pediatric patients. A major challenge in designing functional TEHVs is to mimic both structural and anisotropic mechanical characteristics of the native valve leaflets. To establish a more biomimetic model of TEHV, we fabricated tri-layered scaffolds by combining electrospinning and microfabrication techniques. These c...

L-arginine and tetrahydrobiopterin, but not sodium nitrite partially restored erectile dysfunction in aged rats.
Un O, Yilmaz D, Bayatli N, Kaya E, Gur S
Aging is associated with erectile dysfunction (ED), in which nitric oxide synthase (NOS) activity and NO bioavailability are reduced due to deficiencies of NOS cofactor (tetrahydrobiopterin, BH(4)) and substrate (L-arginine). We determined whether the prolonged treatment with sodium nitrite (NaNO(2)) as a storage form of NO ameliorates ED in aged rats. Male Sprague-Dawley rats were divided: younger, aged and NaNO(2)-treated (20 mg/kg per day) aged groups. The erectile (intracavernosal pressure [...

The CD200-CD200 receptor inhibitory axis controls arteriogenesis and local T lymphocyte influx.
van den Borne P, Rygiel TP, Hoogendoorn A, Westerlaken GH, Boon L, Quax PH, Pasterkamp G, Hoefer IE, Meyaard L
The role of the CD200 ligand-CD200 receptor (CD200-CD200R) inhibitory axis is highly important in controlling myeloid cell function. Since the activation of myeloid cells is crucial in arteriogenesis, we hypothesized that disruption of the CD200-CD200R axis promotes arteriogenesis in a murine hindlimb ischemia model. Female Cd200-/- and wildtype (C57Bl/6J) mice underwent unilateral femoral artery ligation. Perfusion recovery was monitored over 7 days using Laser-Doppler analysis and was increase...

Left ventricular functional recovery and remodeling in low-flow low-gradient severe aortic stenosis after transcatheter aortic valve implantation.
Kamperidis V, Joyce E, Debonnaire P, Katsanos S, van Rosendael PJ, van der Kley F, Sianos G, Bax JJ, Ajmone Marsan N, Delgado V
Background: Speckle-tracking-derived global longitudinal strain (GLS) is a more sensitive method of detecting left ventricular (LV) functional recovery after transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis. However, it remains unknown whether LV function improves in patients with low-flow, low-gradient severe aortic stenosis (LFLGSAS) after TAVI. The aim of the present was to evaluate LV functional recovery and remodeling after TAVI in patients with LFLGSAS...
