Thesis Biochemistry Department of Biosciences University of Kuopio June 2008 Abstract The expression of the human apolipoprotein genes and their regulation by PPARs. UNIVERSITY OF KUOPIO, the Faculty of Natural and Environmental Sciences, Curriculum of Biochemistry USKI Juuso Oskari Thesis for Master of Science degree Supervisors Prof. Carsten Carlberg, Ph.D. Merja Heinäniemi, Ph.D. June 2008 Keywords: nuclear receptors; peroxisome proliferator-activated receptor; PPAR response element; apolipoprotein; lipid metabolism; high density lipoprotein; low density lipoprotein. Lipids are any fat-soluble, naturally-occurring molecules and one of their main biological functions is energy storage. Lipoproteins carry hydrophobic lipids in the water and salt-based blood environment for processing and energy supply in liver and other organs. In this study, the genomic area around the apolipoprotein genes was scanned in silico for PPAR response elements (PPREs) using the in vitro data-based computer program. Several new putative REs were found in surroundings of multiple lipoprotein genes. The responsiveness of those apolipoprotein genes to the PPAR ligands GW501516, rosiglitazone and GW7647 in the HepG2, HEK293 and THP-1 cell lines were tested with real-time PCR. The APOA1, APOA2, APOB, APOD, APOE, APOF, APOL1, APOL3, APOL5 and APOL6 genes were found to be regulated by PPARs in direct or secondary manners. Those results provide new insights in the understanding of lipid metabolism and so many lifestyle diseases like atherosclerosis, type 2 diabetes, heart disease and stroke. -
The Olfactory Receptor Associated Proteome
INTERNATIONAL GRADUATE SCHOOL OF NEUROSCIENCES (IGSN) RUHR UNIVERSITÄT BOCHUM THE OLFACTORY RECEPTOR ASSOCIATED PROTEOME Doctoral Dissertation David Jonathan Barbour Department of Cell Physiology Thesis advisor: Prof. Dr. Dr. Dr. Hanns Hatt Bochum, Germany (30.12.05) ABSTRACT Olfactory receptors (OR) are G-protein-coupled membrane receptors (GPCRs) that comprise the largest vertebrate multigene family (~1,000 ORs in mouse and rat, ~350 in human); they are expressed individually in the sensory neurons of the nose and have also been identified in human testis and sperm. In order to gain further insight into the underlying molecular mechanisms of OR regulation, a bifurcate proteomic strategy was employed. Firstly, the question of stimulus induced plasticity of the olfactory sensory neuron was addressed. Juvenile mice were exposed to either a pulsed or continuous application of an aldehyde odorant, octanal, for 20 days. This was followed by behavioural, electrophysiological and proteomic investigations. Both treated groups displayed peripheral desensitization to octanal as determined by electro-olfactogram recordings. This was not due to anosmia as they were on average faster than the control group in a behavioural food discovery task. To elucidate differentially regulated proteins between the control and treated mice, fluorescent Difference Gel Electrophoresis (DIGE) was used. Seven significantly up-regulated and ten significantly down-regulated gel spots were identified in the continuously treated mice; four and twenty-four significantly up- and down-regulated spots were identified for the pulsed mice, respectively. The spots were excised and proteins were identified using mass spectrometry. Several promising candidate proteins were identified including potential transcription factors, cytoskeletal proteins as well as calcium binding and odorant binding proteins. -
Clusterin and LRP2 Are Critical Components of the Hypothalamic Feeding Regulatory Pathway
ARTICLE Received 21 Sep 2012 | Accepted 16 Apr 2013 | Published 14 May 2013 DOI: 10.1038/ncomms2896 Clusterin and LRP2 are critical components of the hypothalamic feeding regulatory pathway So Young Gil1, Byung-Soo Youn2, Kyunghee Byun3,4, Hu Huang5, Churl Namkoong1, Pil-Geum Jang1, Joo-Yong Lee1, Young-Hwan Jo6, Gil Myoung Kang1, Hyun-Kyong Kim1, Mi-Seon Shin7, Claus U. Pietrzik8, Bonghee Lee3,4, Young-Bum Kim3,5 & Min-Seon Kim1,7 Hypothalamic feeding circuits are essential for the maintenance of energy balance. There have been intensive efforts to discover new biological molecules involved in these pathways. Here we report that central administration of clusterin, also called apolipoprotein J, causes anorexia, weight loss and activation of hypothalamic signal transduction-activated transcript-3 in mice. In contrast, inhibition of hypothalamic clusterin action results in increased food intake and body weight, leading to adiposity. These effects are likely mediated through the mutual actions of the low-density lipoprotein receptor-related protein-2, a potential receptor for clusterin, and the long-form leptin receptor. In response to clusterin, the low-density lipoprotein receptor-related protein-2 binding to long-form leptin receptor is greatly enhanced in cultured neuronal cells. Furthermore, long-form leptin receptor deficiency or hypothalamic low-density lipoprotein receptor-related protein-2 suppression in mice leads to impaired hypothalamic clusterin signalling and actions. Our study identifies the hypotha- lamic clusterin–low-density lipoprotein receptor-related protein-2 axis as a novel anorexigenic signalling pathway that is tightly coupled with long-form leptin receptor-mediated signalling. 1 Asan Institute for Life Science, University of Ulsan College of Medicine, Seoul 138-736, Korea. -

Brain-Specific Lipoprotein Receptors Interact with Astrocyte Derived
ARTICLE https://doi.org/10.1038/s41467-021-22751-7 OPEN Brain-specific lipoprotein receptors interact with astrocyte derived apolipoprotein and mediate neuron-glia lipid shuttling Jun Yin1, Emma Spillman1,5, Ethan S.

To understand how a neuron acquires its lipid supply from specific lipoproteins and their receptors, we perform combined genetic, transcriptome, and biochemical analyses in the developing Drosophila larval brain. Here we report, the astrocyte- derived secreted lipocalin Glial Lazarillo (GLaz), a homolog of human Apolipoprotein D (APOD), and its neuronal receptor, the brain-specific short isoforms of Drosophila lipophorin receptor 1 (LpR1-short), cooperatively mediate neuron-glia lipid shuttling and support den- drite morphogenesis. The isoform specificity of LpR1 defines its distribution, binding partners, and ability to support proper dendrite growth and synaptic connectivity. By demonstrating physical and functional interactions between GLaz/APOD and LpR1, we elucidate molecular pathways mediating lipid trafficking in the fly brain, and provide in vivo evidence indicating isoform-specific expression of lipoprotein receptors as a key mechanism for regulating cell- type specific lipid recruitment. 1 Dendrite Morphogenesis and Plasticity Unit, National Institute of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, MD, USA. 2 The City University of New York, Graduate Center-Advanced Science Research Center, New York, NY, USA. -

Although Accepted 7 May 2012 different efforts have been made to characterize the human brain proteome in depth, the Available online 15 May 2012 protein composition of the human OB remains largely unexplored.

Bioinformatic Proteomics analyses revealed that protein components of the OB participated in a plethora of biological Mass spectrometry process highlighting hydrolase and phosphatase activities and nucleotide and RNA binding Bioinformatics activities. Interestingly, 631 OB proteins identified were not previously described in protein datasets derived from large-scale Human Brain Proteome Project (HBPP) studies. In particular, a subset of these differential proteins was mainly involved in axon guidance, opioid signaling, neurotransmitter receptor binding, and synaptic plasticity. Taken together, these results increase our knowledge about the molecular composition of the human OB and may be useful to understand the molecular basis of the olfactory system and the etiology of its disorders. -

Abstract Background: Olfactory discrimination depends on the large numbers of odorant receptor genes and differential ligand-receptor signaling among neurons expressing different receptors. In this study, we describe an in vitro system that enables the expression of exogenous odorant receptors in cultured olfactory sensory neurons. Olfactory sensory neurons in the culture express characteristic signaling molecules and, therefore, provide a system to study receptor function within its intrinsic cellular environment. -
