Estrogen activates the high-density lipoprotein receptor gene via binding to estrogen response elements and interaction with sterol regulatory element binding protein-1A.
The effects of E2 on the high-density lipoprotein receptor (HDL-R) scavenger receptor class B type I (SR-BI) gene were examined. Four putative estrogen response element half-site motifs (ERE(1/2)) (-2176, -1726, -1622, and -1211, designated ERE(1/2)-1, 2, 3, and 4, respectively) were identified in the HDL-R SR-BI promoter. Transfection studies and mutation analysis demonstrated that E2 signific...
متن کاملEstrogen receptor interaction with estrogen response elements.
The estrogen receptor (ER) is a ligand-activated enhancer protein that is a member of the steroid/nuclear receptor superfamily. Two genes encode mammalian ER: ERalpha and ERbeta. ER binds to specific DNA sequences called estrogen response elements (EREs) with high affinity and transactivates gene expression in response to estradiol (E(2)). The purpose of this review is to summarize how natural ...
متن کاملThe high mobility group protein 1 enhances binding of the estrogen receptor DNA binding domain to the estrogen response element.
We have examined the ability of the high-mobility group protein 1 (HMG1) to alter binding of the estrogen receptor DNA-binding domain (DBD) to the estrogen response element (ERE). HMG1 dramatically enhanced binding of purified, bacterially expressed DBD to the consensus vitellogenin A2 ERE in a dose-dependent manner. The ability of HMG1 to stabilize the DBD-ERE complex resulted in part from a d...
متن کاملMouse Estrogen Receptor b Forms Estrogen Response Element- Binding Heterodimers with Estrogen Receptor a
The recent discovery that an additional estrogen receptor subtype is present in various rat tissues has advanced our understanding of the mechanisms underlying estrogen signaling. Here we report on the cloning of the cDNA encoding the mouse homolog of estrogen receptor-b (ERb) and the functional characterization of mouse ERb protein. ERb is shown to have overlapping DNA-binding specificity with...
متن کاملHuman sterol regulatory element-binding protein 1a contributes significantly to hepatic lipogenic gene expression.
BACKGROUND/AIMS Sterol regulatory element-binding protein (SREBP) 1, the master regulator of lipogenesis, was shown to be associated with non-alcoholic fatty liver disease, which is attributed to its major isoform SREBP1c. Based on studies in mice, the minor isoform SREBP1a is regarded as negligible for hepatic lipogenesis. This study aims to elucidate the expression and functional role of SREB...
