LRP2 Is Associated with Plasma Lipid Levels 311 Original Article
310 Journal of Atherosclerosis and Thrombosis Vol.14, No.6 LRP2 is Associated with Plasma Lipid Levels 311 Original Article Genetic Association of Low-Density Lipoprotein Receptor-Related Protein 2 (LRP2) with Plasma Lipid Levels Akiko Mii1, 2, Toshiaki Nakajima2, Yuko Fujita1, Yasuhiko Iino1, Kouhei Kamimura3, Hideaki Bujo4, Yasushi Saito5, Mitsuru Emi2, and Yasuo Katayama1 1Department of Internal Medicine, Divisions of Neurology, Nephrology, and Rheumatology, Nippon Medical School, Tokyo, Japan. 2Department of Molecular Biology-Institute of Gerontology, Nippon Medical School, Kawasaki, Japan. 3Awa Medical Association Hospital, Chiba, Japan. 4Department of Genome Research and Clinical Application, Graduate School of Medicine, Chiba University, Chiba, Japan. 5Department of Clinical Cell Biology, Graduate School of Medicine, Chiba University, Chiba, Japan. Aim: Not all genetic factors predisposing phenotypic features of dyslipidemia have been identified. We studied the association between the low density lipoprotein-related protein 2 gene (LRP2) and levels of plasma total cholesterol (T-Cho) and LDL-cholesterol (LDL-C) among 352 adults in Japan. Methods: Subjects were obtained from among participants in a cohort study that was carried out with health-check screening in an area of east-central Japan. We selected 352 individuals whose LDL-C levels were higher than 140 mg/dL from the initially screened 22,228 people. We assessed the relation between plasma cholesterol levels and single-nucleotide polymorphisms (SNPs) in the LRP2 gene. Results: -
Potential Microrna-Related Targets in Clearance Pathways of Amyloid-Β
Madadi et al. Cell Biosci (2019) 9:91 https://doi.org/10.1186/s13578-019-0354-3 Cell & Bioscience REVIEW Open Access Potential microRNA-related targets in clearance pathways of amyloid-β: novel therapeutic approach for the treatment of Alzheimer’s disease Soheil Madadi1, Heidi Schwarzenbach2, Massoud Saidijam3, Reza Mahjub4 and Meysam Soleimani1* Abstract Imbalance between amyloid-beta (Aβ) peptide synthesis and clearance results in Aβ deregulation. Failure to clear these peptides appears to cause the development of Alzheimer’s disease (AD). In recent years, microRNAs have become established key regulators of biological processes that relate among others to the development and progres- sion of neurodegenerative diseases, such as AD. This review article gives an overview on microRNAs that are involved in the Aβ cascade and discusses their inhibitory impact on their target mRNAs whose products participate in Aβ clear- ance. Understanding of the mechanism of microRNA in the associated signal pathways could identify novel therapeu- tic targets for the treatment of AD.

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. -
Coexpression of ATP-Binding Cassette Proteins ABCG5 and ABCG8 Permits Their Transport to the Apical Surface
Coexpression of ATP-binding cassette proteins ABCG5 and ABCG8 permits their transport to the apical surface Gregory A. Graf, … , Jonathan C. Cohen, Helen H. Hobbs J Clin Invest. 2002;110(5):659-669. https://doi.org/10.1172/JCI16000. Article Cardiology Mutations in either ATP-binding cassette (ABC) G5 or ABCG8 cause sitosterolemia, an autosomal recessive disorder of sterol trafficking. To determine the site of action of ABCG5 and ABCG8, we expressed recombinant, epitope-tagged mouse ABCG5 and ABCG8 in cultured cells. Both ABCG5 and ABCG8 underwent N-linked glycosylation. When either protein was expressed individually in cells, the N-linked sugars remained sensitive to Endoglycosidase H (Endo H). When ABCG5 and ABCG8 were coexpressed, the attached sugars were Endo H–resistant and neuraminidase-sensitive, indicating that the proteins were transported to the trans-Golgi complex. The mature, glycosylated forms of ABCG5 and ABCG8 coimmunoprecipitated, consistent with heterodimerization of these two proteins. The Endo H–sensitive forms of ABCG5 and ABCG8 were confined to the endoplasmic reticulum (ER), whereas the mature forms were present in non-ER fractions in cultured hepatocytes. Immunoelectron microscopy revealed ABCG5 and ABCG8 on the plasma membrane of these cells. In polarized WIF-B cells, recombinant ABCG5 localized to the apical (canalicular) membrane when coexpressed with ABCG8, but not when expressed alone. To our knowledge this is the first direct demonstration that trafficking of an ABC half-transporter to the cell surface requires the presence of its dimerization partner.

Schanstra4,5, Jerome Zoidakis1, Burkert Pieske6, Harald Mischak2 and Antonia Vlahou1* Abstract Background: Cardiovascular disease (CVD) describes the pathological conditions of the heart and blood vessels. Despite the large number of studies on CVD and its etiology, its key modulators remain largely unknown. To this end, we performed a comprehensive proteomic analysis of blood plasma, with the scope to identify disease-associated changes after placing them in the context of existing knowledge, and generate a well characterized dataset for fur- ther use in CVD multi-omics integrative analysis. Methods: LC–MS/MS was employed to analyze plasma from 32 subjects (19 cases of various CVD phenotypes and 13 controls) in two steps: discovery (13 cases and 8 controls) and test (6 cases and 5 controls) set analysis. Follow- ing label-free quantifcation, the detected proteins were correlated to existing plasma proteomics datasets (plasma proteome database; PPD) and functionally annotated (Cytoscape, Ingenuity Pathway Analysis). Diferential expression was defned based on identifcation confdence ( 2 peptides per protein), statistical signifcance (Mann–Whitney p value 0.05) and a minimum of twofold change.≥ ≤ Results: Peptides detected in at least 50% of samples per group were considered, resulting in a total of 3796 identi- fed proteins (838 proteins based on 2 peptides). Pathway annotation confrmed the functional relevance of the fndings (representation of complement≥ cascade, fbrin clot formation, platelet degranulation, etc.). -

Sitosterolemia is caused by homozygous or compound heterozygous gene mutations in either ATP-binding cassette subfamily G member 5 (ABCG5) or 8 (ABCG8). Since ABCG5 and ABCG8 play pivotal roles in the excretion of neutral sterols into feces and bile, patients with sitosterolemia present elevated levels of serum plant sterols and in some cases also hypercholesterolemia. A 48-year-old woman was referred to our hospital for hypercholesterolemia. She had been misdiagnosed with familial hypercholesterolemia at the age of 20 and her serum low-density lipoprotein cholesterol (LDL-C) levels had remained about 200–300 mg/dL at the former clinic. Although the treatment of hydroxymethylglutaryl-CoA (HMG-CoA) reductase inhibitors was ineffective, her serum LDL-C levels were normalized by ezetimibe, a cholesterol transporter inhibitor. -

(technisch orientiert) Uwe Anzenberger geboren am 22.03.1976 in Singen a. Htwl.

Prof. Dr. Thomas Willnow 2. Prof. Dr. Michael Bader 3. Prof. Dr. Wolfgang Lockau Tag der m¨undlichen Pr¨ufung: 22. September 2006 Abstract LRP2 is a member of the low-density lipoprotein receptor gene family that is mainly expressed in the yolk sac and in the neuroepithelium of the early embryo. Deficiency for this 600 kDa protein in mice results in holoprosencephaly, indicating an important yet unknown role for LRP2 in forebrain development. In this study, mice with a complete or a conditional loss of lrp2 function were used to further elucidate the consequences of the lack of LRP2 expression. This study shows that the presence of LRP2 in the neuroepithelium but not in the yolk sac is crucial for early forebrain development. Lack of the receptor resulted in an increase of Bone morphogenic protein (Bmp) 4 signaling in the rostral telencephalon at E9.5. As a consequence, sonic hedgehog (shh) expression at E10.5 was lost completely in a ventral region of the telencephalon termed anterior entopeduncular area (AEP). The absence of Shh activity in this area subsequently led to the loss of ventrally induced oligodendroglial and interneuronal cell populations in lrp2 deficient mice. -
