  1. 1. Regulation of chloroplast development during the greening process

    Författare :Yan Ji; Åsa Strand; Eevi Rintamäki; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; light response; anterograde signalling; plastid transcription; chloroplast development; photosynthesis; bZIP; PEP complex; de-etiolation; molekylärbiologi; Molecular Biology;

    Sammanfattning : Upon light exposure, the expression of one-third of the nuclear-encoded genes is changing, including genes encoding many chloroplast-targeted proteins responsible for the initiation of plastid transcription and the establishment of photosynthesis. The control of the nuclear-encoded genes involved in the development of chloroplast is referred to as anterograde signalling. LÄS MER

  2. 2. Coordination of two different genomes in response to light and stress

    Författare :Louise Norén Lindbäck; Åsa Strand; Antony Dodd; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; cellular communication; tetrapyrrole; circadian clock; oxidative stress; light signalling; gene regulation; molekylärbiologi; Molecular Biology;

    Sammanfattning : About 1.5 billion years ago, a photosynthetic bacteria was engulfed by a eukaryotic cell which initiated a symbiotic relationship and the evolution of the chloroplast as we know it today. The chloroplast has retained its own genome encoding for a number of proteins required for the function of the chloroplast. LÄS MER

  3. 3. Organelle movement in melanophores: Effects of Panax ginseng, ginsenosides and quercetin

    Författare :Therese Eriksson; Rolf Andersson; Samuel Svensson; Ingemar Lundström; Robert Kronstrand; Per Hammarström; Linköpings universitet; []
    Nyckelord :melanophores; Panax ginseng; ginsenosides; quercetin; organell anterograde transport; endothelin-3; mitogen activated protein kinase; protein kinase C; MEDICINE; MEDICIN;

    Sammanfattning : Panax ginseng is a traditional herb that has been used for over 2000 years to promote health and longevity. Active components of ginseng include ginsenosides, polysaccharides, flavonoids, polyacetylenes, peptides, vitamins, phenols and enzymes, of which the ginsenosides are considered to be the major bioactive constituents.

  4. 4. The chloroplast talks : Insights into the language of the chloroplast in Arabidopsis

    Författare :Peter Kindgren; Åsa Strand; Barry Pogson; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; photosynthesis; retrograde communication; Mg-ProtoIX; oxidative stress; gene expression; Molecular biology; Molekylärbiologi; Physiological Botany; fysiologisk botanik;

    Sammanfattning : The chloroplast originates from an endosymbiotic event 1.5 billion years ago, when a free living photosynthetic bacteria was engulfed by a eukaryotic host. The chloroplastic genome has through evolution lost many genes to the nuclear genome of the host. LÄS MER

  5. 5. Propofol changes the cytoskeletal function in neurons : An experimental study in cortical cultures

    Författare :Dean Turina; Christina Eintrei; Karin Björnström Karlsson; Lindahl Sten; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Propofol; cytoskeleton;

    Sammanfattning : Every day, general anaesthetics are given to a large number of patients around the world but the cellular mechanisms of how anaesthetics act are still not clear. General anaesthetics cause the intended unconsciousness, amnesia and immobility in patients, but also side effects such as a decrease in mean arterial pressure and arrhythmia, both of which contribute to complications such as heart damage and stroke.
