  1. 1. Novel aspects of Na+,K+-ATPase

    University dissertation from Stockholm : Karolinska Institutet, Department of Women's and Children's Health

    Author : Oleg Aizman; Karolinska Institutet.; Karolinska Institutet.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Na; K-A TPase; PKA; PKC; dopamine; ouabain; cell attachment; Ca2 ; oscillations; steroid; transcriptional regulation; IP3R.;

    Abstract : Na,K-ATPase, an integral membrane protein expressed in each eukaryotic cell, serves as the major determinant of intracellular ion composition. In the current study we investigated novel aspects of Na,K-ATPase function and regulation. It is well established that Na,K-ATPase activity is regulated by reversible phosphorylation. READ MORE

  2. 2. Na, K-ATPase as signaling transducer

    University dissertation from Stockholm : Karolinska Institutet, Department of Women's and Children's Health

    Author : Juan Li; Karolinska Institutet.; Karolinska Institutet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : It is now generally agreed that Na,K-ATPase (NKA), in addition to its role in the maintenance of Na+ and K+ gradients across the cell membrane, is a signal transducer. Our group has identified a novel signaling pathway where NKA interact with IP3R to form a signaling microdomain. READ MORE

  3. 3. Canonical and noncanonical transducers for calcium signaling : role of Na,K-ATPase and angiotensin receptor

    University dissertation from Stockholm : Karolinska Institutet, Dept of Women's and Children's Health

    Author : Zuzana Khorshidi; Karolinska Institutet.; Karolinska Institutet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Calcium (Ca2+) is the most universal and versatile signal in the cell. This versatility is based on the speed, amplitude and spatio-temporal patterning of the Ca2+ events. The inositol 1,4,5-trisphosphate receptor (IP3R) is one of the main Ca2+ channels responsible for the Ca2+ release from the intracellular stores. READ MORE

  4. 4. Mathematical Models in Cellular Biophysics

    University dissertation from Stockholm : KTH

    Author : Jacob Kowalewski; KTH.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Calcium oscillations; Diffusion; Dopamine receptors; Mathematical models; Computer simulations; FRAP; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : Cellular biophysics deals with, among other things, transport processes within cells. This thesis presents two studies where mathematical models have been used to explain how two of these processes occur.Cellular membranes separate cells from their exterior environment and also divide a cell into several subcellular regions.

  5. 5. Oxidative stress and calcium signalling : Implications for diabetes and cardiac glycosides

    University dissertation from Stockholm : Karolinska Institutet, Department of Women's and Children's Health

    Author : Mark Lal; Karolinska Institutet.; Karolinska Institutet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Calcium; diabetes; Na; K-ATPase; ouabain; oxidative stress;

    Abstract : The signal transduction processes by which an individual cell is able to recognize and respond to its external environment are critical to determining its survival as well as that of the entire organism. In the current study we have investigated the intracellular signalling cascades activated downstream of two separate stimuli: the diabetic milieu and the cardiac glycoside, ouabain. READ MORE
