    Figure 1. ChIP-seq results obtained with the Diagenode monoclonal antibody directed against ERalpha
    ChIP was performed with the Diagenode monoclonal antibody against ERalpha (cat. No. AC-066-100) on sheared chromatin from MCF7 cells treated for 1 hour with estradiol. The IP’d DNA was analysed with an Illumina Genome Analyzer. Library preparation, cluster generation and sequencing were performed according to the manufacturer’s instructions. The 36 bp tags were aligned to the human genome using the ELAND algorithm. Figure 1 shows the obtained peaks near the TFF1 gene on chromosome 21 (figure 1A), the GREB1 and HAAO genes on chromosome 2 (figure 1B and C), and the ZNF185 gene on the X-chromosome (figure 1D).

  • Target Description

    The estrogen receptor alpha (ERalpha, UniProt/Swiss-Prot entry P03372) belongs to the family of nuclear hormone receptors, which are ligand-activated transcription factors. They are important for the regulation of gene expression, cellular proliferation and differentiation, sexual development and reproductive function. Estrogen receptors are also involved in pathological processes such as breast cancer, and osteoporosis. ERalpha can regulate transcription by direct binding to estrogen response elements (EREs) in the DNA or by interaction with other transcription factors. It may also form a heterodimer with ERbeta.

    Carnobacterium maltaromaticum boosts intestinal vitamin D production tosuppress colorectal cancer in female mice.
    Li Q. et al.
    Carnobacterium maltaromaticum was found to be specifically depleted in female patients with colorectal cancer (CRC). Administration of C. maltaromaticum reduces intestinal tumor formation in two murine CRC models in a female-specific manner. Estrogen increases the attachment and colonization of C.Â...

    27-Hydroxycholesterol, The Estrogen Receptor Modulator, AltersDNA Methylation in Breast Cancer.
    Vini Ravindran et al.
    27-hydroxycholesterol (27-HC) is the first known endogenous selective estrogen receptor modulator (SERM), and its elevation from normal levels is closely associated with breast cancer. A plethora of evidence suggests that aberrant epigenetic signatures in breast cancer cells can result in differential responses to v...

    Epigenetic remodelling of enhancers in response to estrogen deprivationand re-stimulation.
    Sklias Athena et al.
    Estrogen hormones are implicated in a majority of breast cancers and estrogen receptor alpha (ER), the main nuclear factor mediating estrogen signaling, orchestrates a complex molecular circuitry that is not yet fully elucidated. Here, we investigated genome-wide DNA methylation, histone acetylation and transcriptio...

    Estrogen induces dynamic ERα and RING1B recruitment to control gene and enhancer activities in luminal breast cancer
    Zhang Yusheng, Chan Ho Lam, Garcia-Martinez Liliana, Karl Daniel L., Weich Natalia, Slingerland Joyce M., Verdun Ramiro E., Morey Lluis
    RING1B, a core Polycomb repressive complex 1 subunit, is a histone H2A ubiquitin ligase essential for development. RING1B is overexpressed in patients with luminal breast cancer (BC) and recruited to actively transcribed genes and enhancers co-occupied by the estrogen receptor  (ER). Whether ER-induced transcript...

    Identification of ChIP-seq and RIME grade antibodies for Estrogen Receptor alpha.
    Glont SE, Papachristou EK, Sawle A, Holmes KA, Carroll JS, Siersbaek R
    Estrogen Receptor alpha (ERα) plays a major role in most breast cancers, and it is the target of endocrine therapies used in the clinic as standard of care for women with breast cancer expressing this receptor. The two methods ChIP-seq (chromatin immunoprecipitation coupled with deep sequencing) and RIME (Rapi...

    The oestrogen receptor alpha-regulated lncRNA NEAT1 is a critical modulator of prostate cancer.

    The androgen receptor (AR) plays a central role in establishing an oncogenic cascade that drives prostate cancer progression. Some prostate cancers escape androgen dependence and are often associated with an aggressive phenotype. The oestrogen receptor alpha (ERα) is expressed in prostate cancers, independent of AR ...

    Estrogen receptor ligands ameliorate fatty liver through a nonclassical estrogen receptor/Liver X receptor pathway in mice.
    Han SI, Komatsu Y, Murayama A, Steffensen KR, Nakagawa Y, Nakajima Y, Suzuki M, Oie S, Parini P, Vedin LL, Kishimoto H, Shimano H, Gustafsson JÅ, Yanagisawa J
    UNLABELLED: Liver X receptor (LXR) activation stimulates triglyceride (TG) accumulation in the liver. Several lines of evidence indicate that estradiol-17β (E2) reduces TG levels in the liver; however, the molecular mechanism underlying the E2 effect remains unclear. Here, we show that administration of E2 attenuate...

    Functional Genomic Methods to Study Estrogen Receptor Activity.
    Gilfillan S, Fiorito E, Hurtado A
    Estrogen Receptor (ER) is a nuclear receptor that mediates the actions of estrogen and tamoxifen. ER is expressed in a major fraction of human breast cancers. Recently, genomic maps for estrogen- and tamoxifen-ER have been published. Interestingly, estrogen and tamoxifen induce similar genomic interactions and both ...

    ChIP-Seq of ERalpha and RNA polymerase II defines genes differentially responding to ligands.
    Welboren WJ, van Driel MA, et al.,
    We used ChIP-Seq to map ERa-binding sites and to profile changes in RNA polymerase II (RNAPII) occupancy in MCF-7 cells in response to estradiol (E2), tamoxifen or fulvestrant. We identify 10 205 high confidence ERa-binding sites in response to E2 of which 68% contain an estrogen response element (ERE) and only 7% c...
