  1. 1. Regulation of the vascular smooth muscle cell phenotype

    Författare :Henrik Lindskog; Göteborgs universitet.; Gothenburg University.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; embryonic stem cells; vascular smooth muscle cell; smooth muscle cell; pericyte; phenotypic modulation; lipoma preferred partner; ectra-cellular matrix; zinc finger protein 148;

    Sammanfattning : Smooth muscle cells (SMC) are present in many internal organs such as the blood vessels and the gastrointestinal channel. Their main functions are to provide stability to the tissue and to provide contractile capability. SMC are not terminally differentiated but can switch between several phenotypes, which is also known as phenotypic modulation. LÄS MER

  2. 2. Transcriptional and post-transcriptional regulation of vascular smooth muscle cell phenotype - Implications for vascular disease states

    Detta är en avhandling från Lund University: Faculty of Medicine

    Författare :Azra Alajbegovic; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Vascular smooth muscle cells VSMC ; cell phenotype; microRNA; Aneurysm; hypertension; Actin polymerization; GATA6; MRTFA; Vascular disease;

    Sammanfattning : As the world population is pushing toward 8 billion, cardiovascular diseases (CVD) remain the leading cause of death worldwide, representing 30% of all global deaths. A large body of work has recognized that smooth muscle cells (SMCs) surrounding the blood vessels play a prominent role in the development and progression of cardiovascular diseases. LÄS MER

  3. 3. Integration of signalling in smooth muscle caveolae

    Detta är en avhandling från Department of Experimental Medical Science, Lund Univeristy

    Författare :Yulia Shakirova; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caveola; caveolin; detrusor; cavin; smooth muscle contractility; remodelling; NO; vascular dysfunction; smooth muscle; erectile dysfunction;

    Sammanfattning : Caveolae and lipid rafts are plasma membrane microdomains that are considered to play a role in cellular signalling. Caveolins and cavins as well as cholesterol are required for the structure and function of caveolae. The papers summarized in this thesis examine the role of caveolae in smooth muscle function.

  4. 4. Modulaton of gene expression in human aortic smooth muscle cells by Porphyromonas gingivalis : a possible association between periodontitis and atherosclerosis

    Detta är en avhandling från Örebro : Örebro university

    Författare :Boxi Zhang; Torbjörn Bengtsson; Allan Sirsjö; Hazem Khalaf; Julia Davies; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microarray; Angiopoietin; Smooth muscle cells; TNF; Periodontitis; Atherosclerosis; Porphyromonas gingivalis; Cancer; Inflammasome; Biomedicin; Biomedicine;

    Sammanfattning : Porphyromonas gingivalis is a gram-negative, rod-shaped, and anaerobic bacterium that is involved in the pathogenesis of periodontitis. P. gingivalis produces a variety of virulence factors including gingipains and fimbriae. LÄS MER

  5. 5. Modulation of the calcium-force relationship in smooth muscle by polyamines and metabolic inhibition

    Detta är en avhandling från Avdelningen för molekylär och cellulär fysiologi, Institutionen för Fysiologi and Neurovetenskap, Sölvegatan 19, S-223 62, Lund, Sweden. Tel. +46-46-222 7769. Fax +46-46-222 4546

    Författare :Karl Swärd; [1997]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metabolic inhibition; polyamines; excitation-contraction coupling; smooth muscle; intracellular calcium; Physiology; Fysiologi;

    Sammanfattning : The relationship between intracellular free calcium ([Ca2+]i) and force in smooth muscle was investigated in receptor-coupled permeabilized preparations and by fluorimetry of the calcium indicator Fura 2 in intact smooth muscle. The time integral of spontaneous [Ca2+]i transients in the intact rat portal vein was decreased by cyanide and, during tonic contraction, cyanide reduced force without changing [Ca2+]i implying metabolic sensitivity of both membrane excitation and [Ca2+]i - activation of the contractile proteins.
