  1. 1. The Biophysics of Na+,K+-ATPase in neuronal health and disease

    Författare :Evgeny E. Akkuratov; Hjalmar Brismar; Anita Aperia; Stefan Wennmalm; Poul Nissen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Na ; K -ATPase; NMDA receptor; ouabain; phosphoproteome; oligomerization; rapid-onset dystonia-parkinsonism; Biologisk fysik; Biological Physics;

    Sammanfattning : Na+,K+-ATPase is one of the most important proteins in the mammalian cell. It creates sodium and potassium gradients which are fundamental for the membrane potential and sodium-dependent secondary active transport. LÄS MER

  3. 2. Manipulation of potassium ion fluxes to induce apoptosis in lung cancer cells

    Författare :Britta Andersson; Kjell Grankvist; Parviz Behnam-Motlagh; Roger Henriksson; Ola Brodin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Apoptosis; Cisplatin; Intracellular K content; Mesothelioma; Na K ATPase pump; Clinical chemistry; Klinisk kemi;

    Sammanfattning : Apoptosis is a special form of cell death that if non-functional may lead to diseases such as cancer. A reduction of the intracellular potassium ion (K+) content is necessary for activating enzymes important for the execution of apoptosis. LÄS MER

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

    Författare :Zuzana Khorshidi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  5. 4. Signaling to and from the sodium pump : effects of insulin and cardiotonic steroids

    Författare :Olga Kotova; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Na ; K -ATPase; insulin; C-peptide; exercise; in vitro contraction; cardiotonic steroids; ouabain; marinobufagenin; ERK 1 2 MAP kinase; Src; p90 rsk; GSK3; signaling cascade; glycogen synthesis; human skeletal muscle cells; human renal tubular cells; rat skeletal muscle.;

    Sammanfattning : Insulin and proinsulin-connecting peptide (C-peptide) stimulate Na+,K+-ATPase activity. The molecular mechanism by which insulin and C-peptide regulate the Na-pump in differentiated primary human skeletal muscle cells (HSMCs) and primary human renal tubular cells (HRTCs) was determined.

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

    Författare :Mark Lal; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Calcium; diabetes; Na; K-ATPase; ouabain; oxidative stress;

    Sammanfattning : 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. LÄS MER
