1. 1. The Tyrosine Kinase GTK : Signal Transduction and Biological Function

   Författare :Cecilia Annerén; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Protein tyrosine kinases; GTK; SHB; proliferation; survival; differentiation; β cells; pancreatectomy; cytokines; diabetes; PC12 cells; NGF; streptozotocin; focal adhesion kinase; RAP1; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

   Sammanfattning : Protein tyrosine kinases play an important role in the regulation of various cellular processes such asgrowth, differentiation and survival. GTK, a novel SRC-like cytoplasmic tyrosine kinase, was recently cloned from a mouse insulinoma cell line and the present work was conducted in order to find a biological function of GTK in insulin producing and neuronal cells.

3. 2. The effects of growth hormone on opioid-induced toxicity in vitro

   Författare :Erik Nylander; Mathias Hallberg; Alexis Bailey; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; opioids; methadone; morphine; ketobemidone; fentanyl; oxycodone; hydromorphone; insulin-like growth factor; cell viability; NG108-15; SH-SY5Y; hippocampus; cortex; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : There is an ongoing opioid crisis in the United States that is portrayed by a large number of opioid-related deaths. Many of these cases involve commonly used prescription opioids, such as morphine, oxycodone, fentanyl, and methadone. This is concerning and highlights the problems associated with long-term opioid treatment. LÄS MER

4. 3. Activity-regulated retinoic acid signaling in olfactory sensory neurons

   Författare :Hande Login; Staffan Bohm; Mattias Alenius; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mouse olfactory system; RA; neuronal activity; CNG; Cyp26B1; BACE1; Kirrel-2; molekylärbiologi; Molecular Biology;

   Sammanfattning : The aim of the studies included in the thesis is to better understand the interplay between neuronal activity-dependent gene regulation and the bioactive vitamin A metabolite all-trans-retinoic acid (RA) during postnatal development, refinement and maintenance of precise neuronal connectivity using the olfactory sensory neuron (OSN) in the olfactory epithelium (OE) of genetically modified mice as a model. We show that:Inhibition of RA receptor (RAR)-mediated transcription in OSNs reduces expression of the olfactory cyclic nucleotide-gated (CNG) ion channel, which is required for odorant receptor (OR)-mediated stimulus transduction.

5. 4. From dopamine nerve fiber formation to astrocytes

   Författare :Franziska Marschinke; Ingrid Strömberg; Cecilia Lundberg; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dopamine; dopaminergic neurons; astroglia; Cell biology; Cellbiologi; Histology; Histologi; neurologi; Neurology;

   Sammanfattning : Parkinson’s disease (PD) is a progressive neurodegenerative disease and characterized by the loss of dopaminergic (DA) neurons in the substantia nigra in the midbrain. The causes of the disease are still unknown. LÄS MER

7. 5. Sensory neuronal protection & improving regeneration after peripheral nerve injury

   Författare :Andrew McKay Hart; Mikael Wiberg; Angus McGrouther; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; cell death; TUNEL; optical disection; dorsal root ganglion; peripheral nerve; nerve conduit; Schwann cell; glial growth factor; leukaemia inhibitory factor; acetyl-L-carnitine; N-acetyl-cysteine; Neurovetenskap; Neurology; Neurologi; neurokirurgi; Neurosurgery;

   Sammanfattning : Peripheral nerve trauma is a common cause of considerable functional morbidity, and healthcare expenditure. Particularly in the ~15% of injuries unsuitable for primary repair, standard clinical management results in inadequate sensory restitution in the majority of cases, despite the rigorous application of complex microsurgical techniques.
