  2. 1. Imaging the pancreas : new aspects on lobular development and adult constitution

    Author : Andreas Hörnblad; Ulf Ahlgren; Guy Rutter; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 1 diabetes; ß-cell mass; tertiary lymphoid organs; biomedical imaging; optical projection tomography; morphogenesis; pancreas development; gastric lobe; spleen development.; medicinsk genetik; Medical Genetics; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Abstract : The mouse pancreas is a mixed exocrine and endocrine glandconsisting of three lobular compartments: the splenic, duodenal and gastric lobes. During embryogenesis, the pancreas forms from two progenitor populations located on the dorsal and ventral side of the primitive gut tube. READ MORE

    Abstract : Spinal neurons are important in several aspects motor control. For example, the neurons essential for locomotor movements reside in the ventral spinal cord. In this thesis, different motor control functions are being related to neuronal populations defined by their common expression of a gene. READ MORE

  5. 3. Role of MYCN in retinoblastoma : From carcinogenesis to tumor progression

    Author : Hanzhao Zhang; Finn Hallböök; Johan Holmberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MYCN; retinoblastoma; RNA sequencing; cancer; avian; E2F; carcinogenesis; Developmental Neurosciences; Medicinsk utvecklings- och neurobiologi;

    Abstract : Retinoblastoma, a pediatric malignancy of the retina, is primarily driven by the bi-allelic inactivation of the RB1gene. However, a subset of cases are characterized by proficient RB1 functions but with MYCN copy number mutations, suggesting an alternative oncogenic mechanism in the absence of RB1 mutations. READ MORE

  6. 4. Gene Expression in the Brains of Two Lines of Chicken Divergently Selected for High and Low Body Weight

    Author : Sojeong Ka; Finn Hallböök; Tom Porter; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chicken; juvenile body weight; divergent selection; gene expression; DNA microarray; quantitiative RT-PCR; hypothalamus; neural plasticity; melanocortin system; endogenous retrovirus; carnitine palmitoyltransferase-1b; Neurobiology; Neurobiologi; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences;

    Abstract : Artificial divergent selection of chickens for high and low body weight at 8 weeks of age has produced two lines: the high (HWS) and low (LWS) body weight chicken lines. In addition to the difference in body weight, the lines show extreme differences in feeding behaviour and body composition. READ MORE

  7. 5. Bone Morphogenetic Protein Receptors in the Nervous System: Neurotrophic Functions with Emphasis on Catecholaminergic Neurons

    Author : Henrik Bengtsson; Åke Seiger; Uppsala universitet; []
