Genetic analysis of Parkinson disease (PD) has identified several genes whose mutation causes inherited parkinsonism, as well as risk loci for sporadic PD. PTEN-induced kinase 1 (PINK1) and parkin, linked to autosomal recessive PD, act in a common genetic pathway regulating the autophagic degradation of mitochondria, termed mitophagy. We undertook a genome-wide RNAi screen as an unbiased approa...
BACKGROUND Fibroblast growth factor 21 (FGF21) is a metabolic hormone with pleiotropic effects on glucose and lipid metabolism and insulin sensitivity. It acts as a key downstream target of both peroxisome proliferator-activated receptor α and γ, the agonists of which have been used for lipid lowering and insulin sensitization, respectively. However, the role of FGF21 in the cardiovascular syst...
PU.1 Regulates Positive Regulatory Domain I-Binding Factor 1/Blimp-1 Transcription in Lymphoma Cells
Introduction The methylation of CpG island in promoter and its nearby area is one the most important way to inhibit gene expression. aim this study was examine potential relationship between for fatty acid synthase (FASN) sterol regulatory element-binding protein 1 (SREBP-1). Material methods Ten newborn pups gerbils as NB group, 10 adult with normal diet control adults high-fat NAFLD 8-month-o...
Now that numerous high-quality complete genome sequences are available, many efforts are focusing on the "second genomic code", namely the code that determines how the precise temporal and spatial expression of each gene in the genome is achieved. In this regard, the elucidation of transcription regulatory networks that describe combined transcriptional circuits for an organism of interest has ...
OBJECTIVES The aim of this study was to determine the protective mechanisms of wild ginseng cambial meristematic cells (CMCs) on non-alcoholic fatty liver disease in high-fat diet (HFD)-fed mice. METHODS Male C57BL/6 mice received either normal-fat diet or HFD for 10 weeks along with wild ginseng CMCs (75, 150 and 300 mg/kg) or vehicle (0.5% carboxyl methyl cellulose) by oral administration o...
The proteolytic cleavage of sterol regulatory element-binding proteins (SREBPs) is regulated by SREBP cleavage-activating protein (SCAP), which forms complexes with SREBPs in membranes of the endoplasmic reticulum (ER). In sterol-depleted cells, SCAP facilitates cleavage of SREBPs by Site-1 protease, thereby initiating release of active NH2-terminal fragments from the ER membrane so that they c...
Insig-1 and Insig-2 are membrane proteins of the endoplasmic reticulum that regulate lipid metabolism by the following two actions: 1) sterol-induced binding to 3-hydroxy-3-methylglutaryl-coenzyme A reductase, an action that leads to ubiquitination and degradation of the enzyme; and 2) sterol-induced binding to SREBP cleavage-activating protein, an action that blocks the proteolytic processing ...
