  1. 16. Studies of gene fusions and copy number alterations in salivary and adnexal neoplasms

    Författare :Marta Persson; Göteborgs universitet; []
    Nyckelord :cancer genetics; fusion oncogenes; chromosome translocation; MYB; NFIB; CRTC1; MAML2; salivary gland; breast; adenoid cystic carcinoma; mucoepidermoid carcinoma; hidradenoma;

    Sammanfattning : Cancer is a genetic disease caused by the accumulation of genetic changes such as mutations and chromosomal rearrangements. An increasing number of genetic studies of both hematological and solid neoplasms have shown that recurrent chromosome translocations often result in fusion oncogenes. LÄS MER

  3. 17. Role of the dopamine system in motor skill learning : implications for neurodevelopmental disorders

    Författare :Yu Qian; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Dopamine (DA), released by midbrain neurons, is critical for motor performance, motor skill learning, and corticostriatal synaptic plasticity. Dysregulation of DAergic signaling in corticostriatal circuitry has also been implicated in several highly heritable neurodevelopmental disorders, such as attention/deficit hyperactivity disorder (ADHD), which are often associated with deficits in fine motor skills.

  4. 18. Regulators of chromatin and transcription in Drosophila

    Författare :Filip Crona; Mattias Mannervik; Fernando Azorin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transcription; chromatin; co-regulators; CBP; lysine demethylase; KDM4A; Brakeless; Drosophila; utvecklingsbiologi; Developmental Biology;

    Sammanfattning : Development of multicellular organisms is achieved by organized temporal and spatial patterns of gene expression leading to cell differentiation. Chromatin regulators control how the DNA is utilized by altering access of proteins to DNA and thereby function as co-factors in transcription. LÄS MER

  5. 19. Regulation of signal transduction in the striatum by typical and atypical antipsychotic drugs

    Författare :Kerstin Håkansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Adenosine A2A receptor; basal ganglia; cAMP-dependent protein kinase; clozapine; DARPP-32; dopamine D 2 receptor; extracellular signal-regulated protein kinases 1 and 2; extrapyramidal side effects; glutamate AMPA receptor; haloperidol; knockout mouse; phosphorylation; schizophrenia; tyrosine hydroxylase.;

    Sammanfattning : The only effective therapy for schizophrenia is based on the use of antipsychotic drugs. These substances act as dopamine D 2 receptor antagonists and can be classified as typical or atypical. Typical antipsychotics, e.g. LÄS MER

  7. 20. Prevention of beta-cell dysfunction via targeting novel GPCRs in pancreatic islets

    Författare :Rajesh Kumar; Islet cell physiology; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type II Diabetes; GPCR; Pancreatic islets; Estrogen; Alpha-1 antitrypsin.;

    Sammanfattning : The primary aim of this thesis was to investigate the role of G protein coupled receptors (GPCRs) in insulin secretion and beta-cell survival. The second aim was to determine which pathway is involved in insulin release and beta-cell protection via GPCRs. LÄS MER
