Title: GPER mediated estradiol reduces miR-148a to promote HLA-G expression in breast cancer

Abstract

Highlights: • E2 induces the level of miR-148a in MCF-7 and MDA-MB-231 cells. • GPER mediates the E2-induced increase of miR-148a in MCF-7 and MDA-MB-231 cells. • E2-GPER regulates the expression of HLA-G by miR-148a. - Abstract: Breast cancer is the most common malignant diseases in women. miR-148a plays an important role in regulation of cancer cell proliferation and cancer invasion and down-regulation of miR-148a has been reported in both estrogen receptor (ER) positive and triple-negative (TN) breast cancer. However, the regulation mechanism of miR-148a is unclear. The role of estrogen signaling, a signaling pathway is important in development and progression of breast cancer. Therefore, we speculated that E2 may regulate miR-148a through G-protein-coupled estrogen receptor-1 (GPER). To test our hypothesis, we checked the effects of E2 on miR-148a expression in ER positive breast cancer cell MCF-7 and TN cancer cell MDA-MB-231. Then we used GPER inhibitor G15 to investigate whether GPER is involved in regulation of E2 on miR-148a. Furthermore, we analyzed whether E2 affects the expression of HLA-G, which is a miR-148a target gene through GPER. The results showed that E2 induces the level of miR-148a in MCF-7 and MDA-MB-231 cells, GPER mediates the E2-induced increase in miR-148amore » expression in MCF-7 and MDA-MB-231 cells and E2-GPER regulates the expression of HLA-G by miR-148a. In conclusion, our findings offer important new insights into the ability of estrogenic GPER signaling to trigger HLA-G expression through inhibiting miR-148a that supports immune evasion in breast cancer.« less

  • Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) is a vital transcription factor that regulates multiple important biological processes, including the epithelial–mesenchymal transition (EMT) and metastasis of breast cancer. Sinomenine is an isoquinoline well known for its remarkable curative effect on rheumatic and arthritic diseases and can induce apoptosis of several cancer cell types. Recently, sinomenine was reported as a tumor suppressor via inhibiting cell proliferation and inducing apoptosis. However, the role and mechanism of sinomenine in invasion and metastasis of breast cancer are largely unknown. Here, we report that sinomenine suppressed the invasion and migration of MDA-MB-231 and 4T1more » breast cancer cells in a dose-dependent manner. We detected binding of NF-κB to the inhibitor of NF-κB (IκB) after the MDA-MB-231 cells were treated with 0.25, 0.5, and 1 mM sinomenine. Co-IP analysis revealed that sinomenine enhanced the binding of NF-κB and IκB in a dose-dependent manner, suggesting that sinomenine had an effect on inactivation of NF-κB. Western blotting and ELISA approaches indicated that the suppression effect was closely associated with the phosphorylation of IκB kinase (IKK) and its negative regulator CUEDC2. Sinomenine treatment decreased miR-324-5p expression, thus increased the level of its target gene CUEDC2, and then blocked the phosphorylation of IKK through altering the upstream axis. Finally, transfection of a miR-324-5p mimic inhibited the suppression of invasion and metastasis of MDA-MB-231 and 4T1 cell by sinomenine, providing evidence that sinomenine treatment suppressed breast cancer cell invasion and metastasis via regulation of the IL4/miR-324-5p/CUEDC2 axis. Our findings reveal a novel mechanism by which sinomenine suppresses cancer cell invasion and metastasis, i.e., blocking NF-κB activation. - Highlights: • Sinomenine reduced invasion and migration of MDA-MB-231 and 4T1 breast cancer cells. • Sinomenine enhanced combination of NF-κB with IκB and blocked NF-κB activation. • Sinomenine promoted CUEDC2 expression and suppressed IκB kinase phosphorylation. • Sinomenine reduced IL-4 and miR-324-5p levels. • MiR-324-5p inhibited the suppression of invasion and metastasis by sinomenine.« less
  • The retinoblastoma protein-interacting zinc-finger (RIZ) gene, a member of the nuclear protein methyltransferase superfamily, is characterized by the presence of the N-terminal PR domain. The RIZ gene encodes for two proteins, RIZ1 and RIZ2. While RIZ1 contains the PR (PRDI-BF1 and RIZ homologous) domain, RIZ2 lacks it. RIZ gene expression is altered in a variety of human cancers and RIZ1 is now considered to be a candidate tumor suppressor. Estradiol treatment of MCF-7 cells produced a selective decrease of RIZ1 transcript and an increase of total RIZ mRNA. Experiments of chromatin immunoprecipitation indicated that RIZ2 protein expression was controlled bymore » estrogen receptor and RIZ1 had a direct repressor function on c-myc gene expression. To investigate the role of RIZ gene products as regulators of the proliferation/differentiation transition, we analyzed the effects of forced suppression of RIZ1 induced in MCF-7 cells by siRNA of the PR domain-containing form. Silencing of RIZ1 expression stimulated cell proliferation, similar to the effect of estradiol on these cells, associated with a transient increase of c-myc expression.« less
  • The expression of HLA class I Ag by term human amnion epithelial cells was investigated. In immunostaining and FACS analysis, mAb to monomorphic class I Ag reacted extensively with amnion cells, whereas polymorphic mAb reactivity was more limited and variable. Further studies were conducted on amnion cell preparations containing negligible contaminants. Northern analysis with use of locus-specific probes demonstrated that amnion expresses two class lb genes, HLA-E and HLA-G. Radio-immunoprecipitation with use of monomorphic mAb identified two fully glycosylated cell surface class I H chains of 44 and 41 kDa; polymorphic mAbs failed to immunoprecipitate the 41-kDa product, although 44-kDamore » products, typical of class la Ag, were identified in some preparations. Class I H chains were isolated from amnion by affinity chromatography. Microsequencing revealed that the first nine residues of the N-terminus of the 41-kDa product aligned perfectly only with HLA-E. Overall, amnion at term appears to express class lb Ag with limited class la Ag. HLA-G is therefore expressed in two extrafetal epithelia: amnion and trophoblast. Identification of the class lb protein HLA-E-E in amnion epithelium may have implications for preterm labor that can be associated with infection of the placental membranes. 44 refs., 5 figs., 2 tabs.« less
  • NADPH oxidase (NOX) generates reactive oxygen species (ROS) and has been suggested to mediate cell proliferation in some cancers. Here, we show that an increase in the expression of NOX5 long form (NOX5-L) is critical for tumor progression in breast tumor tissues. Immunostaining of clinical samples indicated that NOX5 was overexpressed in 41.1% of breast ductal carcinoma samples. NOX5-L depletion consistently suppressed cell proliferation, invasion, and migration in vitro. Antibody-mediated neutralization of NOX5-L attenuated tumor progression in a mouse xenograft model. Promoter analysis revealed that NOX5-L expression is regulated by STAT5A in breast cancer cells. Based on our novel findings,more » we suggest that inhibition of NOX5-L may be a promising therapeutic strategy that exerts anti-cancer effects via the modulation of ROS-mediated cell signaling. - Highlights: • The ROS-generating protein, NOX5-L, determines cellular proliferation and metastasis in subset of breast tumor. • Tumor growth was attenuated by the treatment of anti-NOX5-L antibody in a xenograft model. • NOX5-L expression is transcriptionally regulated by STAT5A in breast cancer cells.« less
  • Because mammary glands are surrounded by adipose tissues, we hypothesize that the ultra-lipophilic endogenous estrogen-17{beta}-fatty acid esters may have preferential hormonal and carcinogenic effects in mammary tissues compared to other target organs (such as the uterus and pituitary). This hypothesis is tested in the present study. We found that all 46 rats implanted with an estradiol-17{beta} pellet developed large pituitary tumors (average weight = 251 {+-}103 mg) and had to be terminated early, but only 48% of them developed mammary tumors. In addition, approximately one-fourth of them developed a huge uterus. In the 26 animals implanted with a mixture containingmore » estradiol-17{beta}-stearate and estradiol-17{beta}-palmitate (two representative estradiol-17{beta}-fatty acid esters) or in the 29 animals implanted with estradiol-17{beta}-stearate alone (in the same molar dose as estradiol-17{beta}), 73% and 79%, respectively, of them developed mammary tumors, whereas only 3 or 2 animals, respectively, had to be terminated early due to the presence of a large pituitary tumor. Both tumorous and normal mammary tissues contained much higher levels of estrogen esterase than other tissues, which catalyzes the releases of bioactive estrogens from their fatty acid esters. In conclusion, while estradiol-17{beta} is much stronger in inducing pituitary tumor (100% incidence) than mammary tumor, estradiol-17{beta}-fatty acid esters have a higher efficacy than estradiol-17{beta} in inducing mammary tumor and yet it only has little ability to induce uterine out-growth and pituitary tumorigenesis. This study establishes the endogenous estrogen-17{beta}-fatty acid esters as preferential inducers of mammary tumorigenesis.« less
