  1. 21. Single-cell RNA sequencing as a tool to study panarthropod evolution

    Författare :Brenda Irene Medina Jimenez; Ralf Janssen; Graham Budd; Tatjana Haitina; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Single-cell RNA sequencing; EvoDevo; gene expression; tissue dissociation; cell capture; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Panarthropoda is a monophyletic group comprised of arthropods and lobopods, molting animals with a segmented body, paired appendages, dorsal brain, and ventral nerve cords. Evolutionary Developmental Biology (EvoDevo) is an interdisciplinary field that seeks to understand how changes in development form the basis for variations in morphology and phenotypic evolution, including the genetic network underlying these processes.

  3. 22. Behavioural, physiological and morphological correlates of life-history in killifishes − a macroevolutionary approach

    Författare :Simon Eckerström-Liedholm; Alejandro Gonzalez Voyer; Björn Rogell; Alastair Wilson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; brain size evolution; comparative analysis; life-history continuum; risk-taking behaviour; sexual selection; trade-offs; etologi; Ethology;

    Sammanfattning : Life-histories commonly evolve along a continuum from short-lived and fecund, to long-lived and less fecund. Because life-history traits are mostly components of reproduction and survival, understanding the causes and consequences of life-history variation is at the core of evolutionary biology. LÄS MER

  4. 23. Evolution of acetylcholine receptors and study of the anatomy of the mouse brain reward system

    Författare :Julia Pedersen; Dan Larhammar; Arnaud Chatonnet; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ventral Tegmental Area; Mesocorticolimbic system; Glutamate; Optogenetics; Histology; Acetylcholine; Receptor; Muscarininc; Nicotinic; G protein-coupled receptor; Gene duplication; Tetraploidization; Synteny; Paralogon; Ohnolog; Zebrafish; Spotted gar; Neuroscience; Neurovetenskap;

    Sammanfattning : This thesis work is divided in two parts. In the first part, I make use of the transgenic TRPV1-Cre mouse line as a tool to investigate the midbrain ventral tegmental area (VTA). LÄS MER

  5. 24. Genetic Sex Differences in Early Human Neuronal Development : An Investigation in Embryo Tissue and Embryonic Stem Cells

    Författare :Philipp Pottmeier; Elena Jazin; Armin Raznahan; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sex chromosome; gametolog; x y homolog; male; female; sex differences; sex bias; embryonic stem cells; neurodevelopment; neuronal differentiation; neural stem cells; genetics; neurodevelopmental disorders; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi; Neuroscience; Neurovetenskap; Medicinsk genetik; Medical Genetics;

    Sammanfattning : Sex differences in the human body affect many different organs and tissues, some of them have an effect on the human brain and its development. In the developing nervous system, sex differences can bias the number or functionality of neurons, glial cells or synapses. As a result, neural networks might develop with a sex-specific bias.

  7. 25. Functional studies of the Quaking gene : Focus on astroglia and neurodevelopment

    Författare :Katarzyna Radomska; Elena Jazin; Pertti Panula; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; QKI; RNA-binding protein; astrocyte; interferon; GFAP; neurodevelopment; zebrafish; neural progenitor cell;

    Sammanfattning : The RNA-binding protein Quaking (QKI) plays a fundamental role in post-transcriptional gene regulation during mammalian nervous system development. QKI is well known for advancing oligodendroglia differentiation and myelination, however, its functions in astrocytes and embryonic central nervous system (CNS) development remain poorly understood.
