  1. 1. Mitochondrial involvement in cell death : release of pro-apoptotic proteins

    Författare :Erik Norberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In addition to the role of the mitochondria in energy metabolism, these organelles play a key role in cell death signaling. In particular, mitochondrial alterations, such as stimulation of reactive oxygen species (ROS) formation, decreased ATP synthesis, loss of membrane potential and the release of pro-apoptotic proteins from the mitochondrial intermembrane space (IMS), have been shown to be involved in, and often responsible for, various manifestations of cell death.

    Sammanfattning : In all vertebrate species, reproduction is a hormonally controlled process, important for growth and maturation of gonads and germ cells. Production of functional germ cells is of outmost importance to secure the survival of a species. Fish comprises 50% of the known vertebrates and are found in aquatic habitats all over the world.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; environmental science; miljövetenskap;

    Sammanfattning : While the environmental impact of the industrial age is massive, including climate change, pollution, microplastics and habitat loss, our influence reaches further back than many recognize. In Sweden, an early and important activity with large potential impact was the mining and smelting of iron, copper and silver ores over the last ~800 years. LÄS MER
