Abstract

Estrogen-related receptor {alpha} (ERR{alpha}) is an important mediator of mitochondrial biogenesis and function. To investigate the transcriptional network controlling these phenomena, we investigated mitochondrial gene expression in embryonic fibroblasts isolated from ERR{alpha} null mice. Peroxisome proliferator-activated receptor {gamma} coactivator-1{alpha} (PGC-1{alpha}) stimulated mitochondrial gene expression program in control cells, but not in the ERR{alpha} null cells. Interestingly, the induction of levels of mitochondrial oxidative stress protection genes in response to increased PGC-1{alpha} levels was dependent on ERR{alpha}. Furthermore, we found that the PGC-1{alpha}-mediated induction of estrogen-related receptor {gamma} and nuclear respiratory factor 2 (NRF-2), was dependent on the presence of ERR{alpha}. Basal levels of NRF-2 were decreased in the absence of ERR{alpha}. The absence of ERR{alpha} resulted in a decrease in citrate synthase enzyme activity in response to PGC-1{alpha} overexpression. Our results indicate an essential role for ERR{alpha} as a key regulator of oxidative metabolism.

Estrogen-related receptor {alpha} modulates the expression of adipogenesis-related genes during adipocyte differentiation

Journal Article Ijichi, Nobuhiro ; Ikeda, Kazuhiro ; Horie-Inoue, Kuniko ; ... - Biochemical and Biophysical Research Communications

Estrogen-related receptor {alpha} (ERR{alpha}) is an orphan nuclear receptor that regulates cellular energy metabolism by modulating gene expression involved in fatty acid oxidation and mitochondrial biogenesis in brown adipose tissue. However, the physiological role of ERR{alpha} in adipogenesis and white adipose tissue development has not been well studied. Here, we show that ERR{alpha} and ERR{alpha}-related transcriptional coactivators, peroxisome proliferator-activated receptor {gamma} (PPAR{gamma}) coactivator-1{alpha} (PGC-1{alpha}) and PGC-1{beta}, can be up-regulated in 3T3-L1 preadipocytes at mRNA levels under the adipogenic differentiation condition including the inducer of cAMP, glucocorticoid, and insulin. Gene knockdown by ERR{alpha}-specific siRNA results in mRNA down-regulation of fatty acidmore »« less

Effect of fenhexamid and cyprodinil on the expression of cell cycle- and metastasis-related genes via an estrogen receptor-dependent pathway in cellular and xenografted ovarian cancer models

Journal Article Go, Ryeo-Eun ; Kim, Cho-Won ; Choi, Kyung-Chul, E-mail: kchoi@cbu.ac.kr - Toxicology and Applied Pharmacology

ABSTRACT: Fenhexamid and cyprodinil are antifungal agents (pesticides) used for agriculture, and are present at measurable amounts in fruits and vegetables. In the current study, the effects of fenhexamid and cyprodinil on cancer cell proliferation and metastasis were examined. Additionally, the protein expression levels of cyclin D1 and cyclin E as well as cathepsin D were analyzed in BG-1 ovarian cancer cells that express estrogen receptors (ERs). The cells were cultured with 0.1% dimethyl sulfoxide (DMSO; control), 17β-estradiol (E2; 10{sup −9} M), and fenhexamid or cyprodinil (10{sup –5}–10{sup −7} M). Results of a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay showed that fenhexamidmore »« less

Identification, cloning, and expression of human estrogen receptor-{alpha}36, a novel variant of human estrogen receptor-{alpha}66

Journal Article Wang Zhaoyi ; Zhang Xintian ; Shen Peng ; ... - Biochemical and Biophysical Research Communications

The identification and subsequent cloning of the 66-kDa human estrogen receptor (here termed hER-{alpha}66), its 46-kDa splice variant hER-{alpha}46, and the closely related hER-{beta} have had a profound impact on the generation of new understanding of estrogen-mediated functions and led to progress in diagnosis and treatment of human breast cancer. However, a persistent problem has been that not all findings previously reported in estrogen-stimulated cell proliferation can be explained through the known properties of the different estrogen receptors described. As the consequence of a search for alternative mechanisms to account for these different findings, we have now identified, cloned, andmore »« less

Polo-like kinase 2 gene expression is regulated by the orphan nuclear receptor estrogen receptor-related receptor gamma (ERR{gamma})

Journal Article Park, Yun-Yong ; Kim, Seok-Ho ; Kim, Yong Joo ; ... - Biochemical and Biophysical Research Communications

Estrogen receptor-related receptor gamma (ERR{gamma}) is a member of the nuclear receptor family of transcriptional activators. To date, the target genes and physiological functions of ERR{gamma} are not well understood. In the current study, we identify that Plk2 is a novel target of ERR{gamma}. Northern blot analysis showed that overexpression of ERR{gamma} induced Plk2 expression in cancer cell lines. ERR{gamma} activated the Plk2 gene promoter, and deletion and mutational analysis of the Plk2 promoter revealed that the ERR{gamma}-response region is located between nucleotides (nt) -2327 and -2229 and -441 and -432 (relative to the transcriptional start site at +1).

Ginsenoside Rg3 increases nitric oxide production via increases in phosphorylation and expression of endothelial nitric oxide synthase: Essential roles of estrogen receptor-dependent PI3-kinase and AMP-activated protein kinase

Journal Article Hien, Tran Thi ; Kim, Nak Doo ; Pokharel, Yuba Raj ; ... - Toxicology and Applied Pharmacology

We previously showed that ginsenosides increase nitric oxide (NO) production in vascular endothelium and that ginsenoside Rg3 (Rg3) is the most active one among ginseng saponins. However, the mechanism for Rg3-mediated nitric oxide production is still uncertain. In this study, we determined whether Rg3 affects phosphorylation and expression of endothelial nitric oxide synthase (eNOS) in ECV 304 human endothelial cells. Rg3 increased both the phosphorylation and the expression of eNOS in a concentration-dependent manner and a maximal effect was found at 10 {mu}g/ml of Rg3.
