  1. 1. Cellular remodeling in response to nutrient exhaustion : From membrane contact sites to autophagy

    Author : Mahsa Ebrahimi; Sabrina Büttner; Cristina Mazzoni; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Aging and longevity; yeast; phosphate restriction; interorganellar communication; autophagy; MVB pathway; NVJs; lipid droplets; nutritional regimes; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Adaptation to fluctuating environments is critical for cellular fitness and survival. Cells need to sense changes in their surroundings and quickly adjust cellular homeostasis and metabolism accordingly. READ MORE

  2. 2. Interorganellar connectivity : From protein to lipid homeostasis

    Author : Carlotta Peselj; Sabrina Büttner; Tim Levine; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Interorganellar connectivity; nucleus; NVJs; chronic lipid bilayer stress; glucose and phosphate exhaustion; nutritional regimes; transmembrane chaperone; IPTP; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Interorganellar connectivity is fundamental for the maintenance of organellar and cellular functionality and viability. This is achieved and maintained by a complex network of signaling cascades, vesicle trafficking between organelles as well as by establishment of direct physical contact at membrane contact sites (MCS).

  3. 3. Development and maintenance of quality indicators in pheasants

    Author : Thomas Ohlsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PHA; ELISA; immunocompetence; carotenoid coloration; male ornaments; fluctuating asymmetry; growth; early development; Phasianus colchicus; egg size; sexual selection; Animal ecology; Djurekologi; Ecology; Ekologi;

    Abstract : Females often base their choice of mates on the expression, size or intensity, of male sexual ornaments. Indicator models of sexual selection assume that females assess male genetic quality through the expression of these secondary sexual characters. READ MORE

  4. 4. Roughage Feeding of Suckler Cows during Winter : intake, utilization and energy status in pregnant cows

    Author : Mikaela Jardstedt; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Abstract : Feeding late cut forage is a common strategy to provide pregnant suckler cows with feed of suitable nutritional quality during ad libitum feeding regimes. Despite this method, commonly grown grasses may result in overfeeding with energy and protein in relation to cow nutrient demands. READ MORE

  5. 5. Metal homeostasis as critical determinant for cellular fitness

    Author : Jutta Diessl; Sabrina Büttner; Rajini Rao; Stockholms universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; metal homeostasis; manganese toxicity; coenzyme Q synthesis; mitochondrial respiration; calcineurin signaling; Pmr1; SPCA1; calcium; survival; caloric restriction; Parkinson’s disease models; proteotoxicity; Pep4; cathepsin D; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Metals play a crucial role in cellular biology. Bulk and trace metals such as calcium and manganese regulate a plethora of cellular processes ranging from signaling and oxidative stress to proteostasis and energy metabolism. READ MORE
