  1. 21. The role of ion channels and intracellular metal ions in apoptosis of Xenopus oocytes

    Författare :Ulrika Englund; Fredrik Elinder; Johan Brask; Katarina Kågedal; Dan Klaerke; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Apoptosis is one type of programmed cell death, important during tissue development and to maintain the tissue homeostasis. Apoptosis comprises a complex network of internal signaling pathways, and an important part of this signaling network is the action of voltage‐gated ion channels. LÄS MER

  3. 22. Caspase activation in human neuroblastoma cells: mechanisms and spatiotemporal aspects

    Författare :Elena V. Ivanova; Kerstin Iverfeldt; Boris Zhivotovsky; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; apoptosis; caspase; local caspase activation; neurodegeneration; tau-anchored FRET sensors; tAFS; cancer; neuroblastoma; TNF-related apoptosis inducing ligand; TRAIL; protein kinase C; PKC; X-linked inhibitor of apoptosis protein; XIAP; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Apoptosis is one of the modes of programmed cell death, in which several members of the caspase family of proteases play the central role. However, activation of apoptotic caspases does not necessarily lead to cell death. LÄS MER

  4. 23. Cell-penetrating peptide targeting mitochondria : Design, synthesis, characterization, and biological effects

    Författare :Carmine Pasquale Cerrato; Ülo Langel; Lena Mäler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cell-penetrating peptide; mitochondrial targeting; ROS reduction; mitochondrial membrane potential; antioxidant activity; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : More than twenty years after the discovery of the first cell-penetrating peptide (CPP), a large number of both naturally occurring as well as engineered CPPs have been discovered. Generally, CPPs are short polycationic sequences of less than 30 amino acids that are able to translocate different cargoes into cells. LÄS MER

  5. 24. Changes in global gene expression and auxin dynamics during embryo development in conifers

    Författare :Daniel Vestman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Conifers are of great economical importance, but our knowledge about how the development of conifers is regulated is limited. The over-all aim of this study has been to gain a better understanding of the molecular regulation of embryo development in conifers. LÄS MER

  7. 25. Autophagic programmed cell death in the suspensor and endosperm of Vicia faba : An ultrastructural study

    Författare :Ulla Wredle; Björn Walles; Áron Keresztes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi;

    Sammanfattning : Programmed cell death (PCD) is a widely spread phenomenon among multi-cellular organisms. Without the deletion of cells no longer needed, the organism will not be able to develop in a predicted way. LÄS MER
