1. Enzymatic Regulation of Steroidogenesis and Nuclear Receptor Activation : Special Focus on Vitamin D and Sex Hormones
Sammanfattning : Enzyme-catalyzed reactions are important to regulate steroidogenesis and nuclear receptor activation. The present investigation examines the role of steroid metabolism catalyzed by CYP7B1 for regulation of hormone receptor activation and the effects of vitamin D on enzymatic regulation of steroidogenesis.

2. Nuclear receptor corepressor N-CoR : role in transcriptional repression
Sammanfattning : The human body consists of a multitude of cells of varying appearance and function. With a few exceptions they are genetically identical, and the key to their divergence lies in their different specific patterns of gene expression. LÄS MER
3. Nuclear medicine methods in idiopathic Parkinsonism : pre- and postsynaptic dopamine SPECT
Sammanfattning : Background: Single photon emission computed tomography (SPECT) with dopamine transporter (DAT) and dopamine D2 receptor (D2R) ligands can visualise the integrity of the nigrostriatal dopamine system. Parkinson’s disease (PD) and the atypical parkinsonian diseases (APD), progressive supranuclear palsy (PSP) and multiple system atrophy (MSA), have similar symptoms and dopamine depletion, but differ in pharmacological response and prognosis.

4. Theranostics in Neuroendocrine Tumors : Somatostatin Receptor Imaging and Therapy
Sammanfattning : Neuroendocrine tumors (NETs) are characterized by cellular overexpression of somatostatin receptors (SSTR), which allows for the use of radiolabeled somatostatin analogs (SSA) for both imaging and therapy. Because NETs often are diagnosed at a metastatic stage, curative surgery is not possible. LÄS MER
5. Functional studies on the nuclear receptor Nurr1
Sammanfattning : The nuclear receptor (NR) superfamily comprises the largest family of ligand-activated transcription factors in eukaryotes, and it plays critical roles in many aspects of vertebrate development and physiology. The NR family is well conserved throughout evolution, and is found in organisms as diverse as nematodes, flies and mammals. LÄS MER
