  2. 16. A genomic approach to smooth muscle differentiation and diversity

    Author : Sven Nelander; Göteborgs universitet; []
    Keywords : Keywords: smooth muscle; phenotype; transcriptional regulation; differentiation; transcriptome; microarray; computational prediction; co-expression network; regulatory sequence analysis; gene module; gene battery;

    Abstract : Smooth muscle cells (SMCs) are a broad class of contractile cells that are found in a number of organs systems, including the vasculature, the urogenital system, the bronchi and the gastrointestinal tract. The two main functions exerted by SMCs are to provide contractile force and to synthesize structural components of the extracellular matrix. READ MORE

  4. 17. 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.

  5. 18. lnvestigating intestinal smooth muscle dysfunction in the 6-OHDA rat model of Parkinson's disease

    Author : Maria del Pilar Murillo; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intestinal motility; smooth muscle; enteric nervous system; dopamine neurodegeneration;

    Abstract : The neurodegenerative progression of the nigrostriatal pathway in Parkinson’s disease (PD) entails the appearance of motor and nonmotor symptoms. Nonmotor symptoms are common, having a negative impact on the quality of life of patients living with PD. READ MORE

  6. 19. Calcium channel activity and force regulation in smooth muscle: Effects of polyamines and growth stimulation

    Author : Maria Gomez; Kardiovaskulär forskning - immunitet och ateroskleros; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; verapamil; tissue culture; portal vein; patch-clamp; calcium; spermidine; spermine; polyamines; excitation-contraction; smooth muscle; calcium channel; ionomycin.; Physiology; Fysiologi;

    Abstract : The initial signal for contraction in smooth muscle is an increase in [Ca2+]i. Ca2+ ions can either enter the cytosol from the extracellular medium or be released from intracellular stores. Voltage-operated Ca2+ channels (VOC) play a dominant role in the activation of smooth muscle contraction. READ MORE

  7. 20. Developmental origin and molecular regulation of vascular smooth muscle cells

    Author : Per Wasteson; Göteborgs universitet; []
    Keywords : smooth muscle cell; aorta; cell origin; lateral plate mesoderm; paraxial mesoderm; lipoma preferred partner; serum response factor; neointimal hyperplasia; angiotensin II; platelet-derived growth factor-B;

    Abstract : Several pathologies of the vascular system have been suggested to be dependent on the smooth muscle cells (SMCs) that build up the vessel wall. Aortic SMCs have been proposed to derive from lateral plate mesoderm. READ MORE
