Na+/H+ exchanger isoform 1-induced osteopontin expression facilitates cardiomyocyte hypertrophy
Download2015-01-01
Mohamed, Iman A., Gadeau, Alain-Pierre, Fliegel, Larry, Lopaschuk, Gary, Mlih, Mohamed, Abdulrahman, Nabeel, Filmore, Natasha, Mraiche, Fatima
Enhanced expression and activity of the Na+/H+ exchanger isoform 1 (NHE1) has been implicated in cardiomyocyte hypertrophy in various experimental models. The upregulation of NHE1 was correlated with an increase in osteopontin (OPN) expression in models of cardiac hypertrophy (CH), and the...

Malignant glioma (MG), comprised of grade III (anaplastic astrocytoma) and grade IV (glioblastoma) astrocytoma, is the most common adult brain tumour, with an incidence of ~4 in 100 000 people. Despite aggressive treatment with surgery, radiation, and chemotherapy, survival remains dismal, with...

Jacob-Ferreira, Anna Laura, Kondo, Marcia Yuri, Baral, Pravas Kumar, James, Michael N., Holt, Andrew, Fan, Xiaohu, Schulz, Richard
Matrix metalloproteinase-2 (MMP-2) is a key intra- and extra-cellular protease which contributes to several oxidative stress related pathologies. A molecular understanding of 72 kDa MMP-2 activity, directly mediated by S-glutathiolation of its cysteine residues in the presence of peroxynitrite...

Practical Considerations for Body Composition Assessment of Adults with Class II/III Obesity Using Bioelectrical Impedance Analysis or Dual-Energy X-Ray Absorptiometry
Download2016-09-03
Johnson Stoklossa, Carlene A., Forhan, Mary, Padwal, Raj S., Gonzalez, Maria Cristina, Prado, Carla M.
Purpose of Review The purpose of this review is to explore the practical considerations for body composition assessment of adults with class II/III obesity. Studies assessing adults (18–64 years) with a body mass index (BMI) ≥35 kg/m2 with bioelectrical impedance analysis (BIA) and/or dual-energy...

Protein Kinase Mediated Regulation of the Na+/H+ Exchanger in the Rat Myocardium by MAP-Kinase-dependent Pathways
Download1999-01-01
Moor, Andrea Noor, Fliegel, Larry
We examined regulation of the Na+/H+ exchanger isoform 1 by phosphorylation in the rat myocardium. We utilized cell extracts from adult rat hearts, adult rat extracts fractionated by fast performance liquid chromatography, and extracts from cultured neonatal cardiac myocytes. The...

Regulation of microtubule dynamics is essential for many cellular processes, including proper assembly and function of the mitotic spindle. One mechanism for temporal and spatial regulation of microtubule dynamics is provided by the kinesin-13 microtubule depolymerizing enzymes, among which MCAK...

Regulation of Cardiac Gap Junctional Communication: Metabolic regulation of Cx40 and Cx43 via phosphorylation
DownloadFall 2015
Alterations in myocardial metabolism and cardiac electrophysiology associated with structural heart disease generate lethal arrhythmias. Differential levels of energy (ATP) supply and demand are generated with structural heart disease that is expected to activate 5’-amp activated protein kinase...

Rho-Kinase-Mediated Diphosphorylation of Myosin Regulatory Light Chain is a Unique Biochemical Mechanism in Human Uterine Myocytes
DownloadFall 2011
Rationale: Smooth muscle (SM) contraction results from activation of the cellular contractile machinery by phosphorylation of myosin regulatory light chain (RLC) at S19 (pRLC) by RLC kinase (MLCK). Subsequent phosphorylation at T18 yields diphosphorylated-RLC (ppRLC), which has been shown to...
