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

   Author : Henrik Lindskog; Göteborgs universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

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

   Author : Azra Alajbegovic; Molekylär kärlfysiologi; []
   Keywords : 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;

   Abstract : 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. READ MORE

5. 3. Integration of signalling in smooth muscle caveolae

   Author : Yulia Shakirova; Cellulär biomekanik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caveola; caveolin; detrusor; cavin; smooth muscle contractility; remodelling; NO; vascular dysfunction; smooth muscle; erectile dysfunction;

   Abstract : 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.

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

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

   Abstract : 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. READ MORE

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

   Author : Karl Swärd; Cellulär biomekanik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metabolic inhibition; polyamines; excitation-contraction coupling; smooth muscle; intracellular calcium; Physiology; Fysiologi;

   Abstract : 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.
