Regulation of apoA-I gene expression: mechanism of action of estrogen and genistein.
We have previously shown that 17-beta-estradiol (E2) and genistein increase the expression of apolipoprotein A-I (apoA-I), the major protein component of HDL, in Hep G2 cells. To elucidate the mechanism mediating the increase in apoA-I gene expression by these compounds, plasmid constructs containing serial deletions of the apoA-I promoter region were generated. The smallest region maintaining ...
متن کاملType 1 Deiodinase Regulates ApoA-I Gene Expression and ApoA-I Synthesis Independent of Thyroid Hormone Signaling.
OBJECTIVE Plasma levels of high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A-I (ApoA-I) are reduced in individuals with defective insulin signaling. Initial studies using liver-specific insulin receptor (InsR) knockout mice identified reduced expression of type 1 deiodinase (Dio1) as a potentially novel link between defective hepatic insulin signaling and reduced expression of t...
متن کاملFGF19 signaling cascade suppresses APOA gene expression.
OBJECTIVE Lipoprotein(a) is a highly atherogenic lipoprotein, whose metabolism is poorly understood. Currently no safe drugs exists that lower elevated plasma lipoprotein(a) concentrations. We therefore focused on molecular mechanisms that influence apolipoprotein(a) (APOA) biosynthesis. METHODS AND RESULTS Transgenic human APOA mice (tg-APO mice) were injected with 1 mg/kg of recombinant hum...
متن کاملTissue-specific expression of apolipoprotein A-I (ApoA-I) is regulated by the 5'-flanking region of the human ApoA-I gene.
We have isolated and characterized a 2.5-kilobase pairs genomic DNA fragment which includes the 5'-flanking region and the first and second exons of the human apolipoprotein (apo) A-I gene. The major transcriptional start site was determined by primer extension analysis and is 235 base pairs (bp) upstream from the AUG translational start codon in liver and 234 bp upstream in the intestine. TATA...
متن کاملDifferential tissue-specific expression of human apoA-I and apoA-II.
To evaluate the sources of high density lipoprotein (HDL) particles containing only apolipoprotein A-I (apoA-I), the synthesis of apoA-I and apolipoprotein A-II (apoA-II) was examined in human liver and small intestine as well as the human intestinally derived cell line, Caco-2. Human liver contained apoA-I, apoA-II as well as apolipoprotein B (apoB) mRNA. In contrast, human adult small intesti...
