  • Desmin Interacts Directly with Mitochondria

They connect contractile myofibrils to plasma membrane, nuclei, and mitochondria. Disturbance of their network due to desmin mutations or deficiency leads to an infringement of myofibril organization and to a deterioration of mitochondrial distribution, morphology, and functions. The nature of the interaction of desmin IFs with mitochondria is not clear. To elucidate the possibility that desmin can directly bind to mitochondria, we have undertaken the study of their interaction in vitro. Using desmin mutant Des(Y122L) that forms unit-length filaments (ULFs) but is incapable of forming long filaments and, therefore, could be effectively separated from mitochondria by centrifugation through sucrose gradient, we probed the interaction of recombinant human desmin with mitochondria isolated from rat liver. Our data show that desmin can directly bind to mitochondria, and this binding depends on its N-terminal domain.

  • Large-Scale Opening of Utrophints Tandem Calponin Homology (CH
    Large-scale opening of utrophin’s tandem calponin homology (CH) domains upon actin binding by an induced-fit mechanism Ava Y. Lin, Ewa Prochniewicz, Zachary M. James, Bengt Svensson, and David D. Thomas1 Department of Biochemistry, Molecular Biology and Biophysics, University of Minnesota, Minneapolis, MN 55455 Edited by James A. Spudich, Stanford University School of Medicine, Stanford, CA, and approved June 20, 2011 (received for review April 21, 2011) We have used site-directed spin labeling and pulsed electron has prevented the development of a reliable structural model for paramagnetic resonance to resolve a controversy concerning the any of these complexes. A major unresolved question concerns structure of the utrophin–actin complex, with implications for the the relative disposition of the tandem CH domains (CH1 and pathophysiology of muscular dystrophy. Utrophin is a homolog of CH2) (9, 10). Crystal structures of the tandem CH domains dystrophin, the defective protein in Duchenne and Becker muscular showed a closed conformation for fimbrin (11) and α-actinin (12), dystrophies, and therapeutic utrophin derivatives are currently but an open conformation for both utrophin (Utr261) (Fig. 1A) being developed. Both proteins have a pair of N-terminal calponin and dystrophin (Dys246) (16). The crystal structure of Utr261 homology (CH) domains that are important for actin binding. suggests that the central helical region connecting CH1 and CH2 Although there is a crystal structure of the utrophin actin-binding is highly flexible. Even for α-actinin, which has a closed crystal domain, electron microscopy of the actin-bound complexes has structure, computational analysis suggests the potential for a high produced two very different structural models, in which the CH do- degree of dynamic flexibility that facilitates actin binding (17).

  • Cyclin D1/Cyclin-Dependent Kinase 4 Interacts with Filamin a and Affects the Migration and Invasion Potential of Breast Cancer Cells
    Published OnlineFirst February 28, 2010; DOI: 10.1158/0008-5472.CAN-08-1108 Tumor and Stem Cell Biology Cancer Research Cyclin D1/Cyclin-Dependent Kinase 4 Interacts with Filamin A and Affects the Migration and Invasion Potential of Breast Cancer Cells Zhijiu Zhong, Wen-Shuz Yeow, Chunhua Zou, Richard Wassell, Chenguang Wang, Richard G. Pestell, Judy N. Quong, and Andrew A. Quong Abstract Cyclin D1 belongs to a family of proteins that regulate progression through the G1-S phase of the cell cycle by binding to cyclin-dependent kinase (cdk)-4 to phosphorylate the retinoblastoma protein and release E2F transcription factors for progression through cell cycle. Several cancers, including breast, colon, and prostate, overexpress the cyclin D1 gene. However, the correlation of cyclin D1 overexpression with E2F target gene regulation or of cdk-dependent cyclin D1 activity with tumor development has not been identified. This suggests that the role of cyclin D1 in oncogenesis may be independent of its function as a cell cycle regulator. One such function is the role of cyclin D1 in cell adhesion and motility. Filamin A (FLNa), a member of the actin-binding filamin protein family, regulates signaling events involved in cell motility and invasion. FLNa has also been associated with a variety of cancers including lung cancer, prostate cancer, melanoma, human bladder cancer, and neuroblastoma. We hypothesized that elevated cyclin D1 facilitates motility in the invasive MDA-MB-231 breast cancer cell line. We show that MDA-MB-231 motility is affected by disturbing cyclin D1 levels or cyclin D1-cdk4/6 kinase activity.

Allan Butterfield and Joshua B. Owen Department of Chemistry, Center of Membrane Sciences, and Sanders-Brown Center on Aging, University of Kentucky, Lexington KY, USA Alzheimer disease (AD) is a neurodegenerative disorder characterized pathologically by the Received: July 7, 2010 accumulation of senile plaques and neurofibrillary tangles, and both these pathological Revised: August 4, 2010 hallmarks of AD are extensively modified by glycosylation. Mounting evidence shows that Accepted: August 10, 2010 alterations in glycosylation patterns influence the pathogenesis and progression of AD, but the vast number of glycan motifs and potential glycosylation sites of glycoproteins has made the field of glycobiology difficult. However, the advent of glycoproteomics has produced major strides in glycoprotein identification and glycosylation site mapping. The use of lectins, proteins that have strong affinity for specific carbohydrate epitopes, to enrich glycoprotein fractions coupled with modern MS, have yielded techniques to elucidate the glycoproteome in AD. Proteomic studies have identified brain proteins in AD and arguably the earliest form of AD, mild cognitive impairment, with altered affinity for Concanavalin-A and wheat germ agglutinin lectins that are consistent with the pathology and progression of this disorder. This is a relatively nascent field of proteomics research in brain, so future studies of lectin-based brain protein separations may lead to additional insights into AD pathogenesis and progression.

  • The Wiskott-Aldrich Syndrome: the Actin Cytoskeleton and Immune Cell Function
    Disease Markers 29 (2010) 157–175 157 DOI 10.3233/DMA-2010-0735 IOS Press The Wiskott-Aldrich syndrome: The actin cytoskeleton and immune cell function Michael P. Blundella, Austen Wortha,b, Gerben Boumaa and Adrian J. Thrashera,b,∗ aMolecular Immunology Unit, UCL Institute of Child Health, London, UK bDepartment of Immunology, Great Ormond Street Hospital NHS Trust, Great Ormond Street, London, UK Abstract. Wiskott-Aldrich syndrome (WAS) is a rare X-linked recessive primary immunodeficiency characterised by immune dysregulation, microthrombocytopaenia, eczema and lymphoid malignancies. Mutations in the WAS gene can lead to distinct syndrome variations which largely, although not exclusively, depend upon the mutation. Premature termination and deletions abrogate Wiskott-Aldrich syndrome protein (WASp) expression and lead to severe disease (WAS). Missense mutations usually result in reduced protein expression and the phenotypically milder X-linked thrombocytopenia (XLT) or attenuated WAS [1–3]. More recently however novel activating mutations have been described that give rise to X-linked neutropenia (XLN), a third syndrome defined by neutropenia with variable myelodysplasia [4–6]. WASP is key in transducing signals from the cell surface to the actin cytoskeleton, and a lack of WASp results in cytoskeletal defects that compromise multiple aspects of normal cellular activity including proliferation, phagocytosis, immune synapse formation, adhesion and directed migration.

The aim myocardial disorders in which the heart muscle is of this study was to analyze TNNT2 gene exons in patients with structurally and functionally abnormal, in the absence of HCM and DCM diagnosis to improve diagnostic and genetic coronary artery disease, hypertension, valvular disease consultancy in affected families. All 15 exons and their flanking and congenital heart disease sufficient to cause the regions of the TNNT2 gene were analyzed by DNA sequence observed myocardial abnormality (Elliott et al. 2008). analysis in 174 patients with HCM and DCM diagnosis. We According to the morphological and functional phenotype identified genetic variations in TNNT2 exon regions in 56 patients the diagnosis of hypertrophic and dilated cardiomyopathy and genetic variations in TNNT2 intron regions in 164 patients.
