Novel Thyrointegrin αvβ3 antagonist (fp-PMT) with potent affinity in the treatment of cancer

ABSTRACT: Microarray analysis was carried out on Glioblastoma (GBM 10181360, GBM 021913 and U87 cells), Bladder cancer (JBV253), skin cancer (A375) and Acute Myelod Leukemia (AML) (KG1A and K562 cells) exposed to fb-PMT at 30 µM concentration. Our genome-wide microarray screens demonstrated that fb-PMT appears to exert its potent anticancer actions on human cancer cells through the molecular interference mechanism with multiple signaling pathways supporting growth and survival of leukemic cells. Notably, fb-PMT had a significant effect on different molecular pathways that contribute to the anticancer activity such as cell cycle control (MYC), survival and maintenance of stem cells (HIF1A; TFAP2C), essential features of the malignant phenotype (TWIST1; SNAI). Furthermore, the fb-PMT-induced significant transcriptional pathway’s activation includes RB1; IRF9; MAML1; RAP1A; and GATA4 pathways, which known to play an important role in anticancer activity. Finally, Consistent with our previous reports on the crosstalk between integrin αvβ3 and ERα which contributes to the induced proliferation of cancer cells, we found that fb-PMT interference with estrogen signaling. The αvβ3 agonist (thyroid hormone) was associated with increased phosphorylation and nuclear enrichment of estrogen receptor α (ERα).

The NDUF and ATP genes are also relevant to control of oxidative phosphorylation and transcription. Six additional NDUF genes linked to oxidative phosphorylation were affected. Conclusions. fb-PMT caused downregulation of expression of a panel of genes involved in electron transport, oxidative phosphorylation, and cytoplasmic ribosomal protein generation in MOH cells. A key component of the anticancer activity of fb-PMT relates to disordering of ATP generation mechanisms in tumor cells.

Estrogen Receptor alpha and Histone Lysine Methyltransferase DOT1L chromatin bound interactome

Project description:Estrogen Receptor alpha (ERα) is a ligand-inducible transcription factor that mediates estrogen signaling in hormone-responsive breast cancer (BC) and is the primary target of specific anticancer therapies. Although ERα blockade with these drugs is effective, the development of a resistance to treatment represents the key problem in clinical management of patients affected by this disease. Understanding the molecular mechanisms underlying ERα action in BC cells may help the identification of new therapeutic targets for more effective pharmacological treatment of endocrine therapy-resistant tumors. We recently discovered the epigenetic enzyme DOT1L (DOT1 Like Histone Lysine Methyltransferase) as a novel nuclear partner of ERα in BC cells. To investigate the involvement of DOT1L in mediating ERα actions in hormone-responsive and endocrine-resistant BC, physical and functional interaction between these two molecules on chromatin was mapped by Chromatin Immunoprecipitation coupled to Mass Spectrometry (ChIP-MS).

DOT1 Like Histone Lysine Methyltransferase (DOT1L) and Menin 1 (MEN1) interaction proteomics in breast cancer cell nuclei

Project description:Estrogen Receptor alpha (ERα) is a ligand-inducible transcription factor that mediates estrogen signaling in hormone-responsive breast cancer (BC) and is the primary target of specific anticancer therapies that although effective can generate resistance phenomena that represents a crucial problem in clinical management of patients affected by this disease. DOT1 Like Histone Lysine Methyltransferase (DOT1L) and Menin 1 (MEN1) have been identified as functional component of the ERα mechanism of action. To investigate the involvement of DOT1L and MEN1 in mediating ERα actions in hormone-responsive and endocrine-resistant BC, interaction proteomics was applied to map the DOT1l and MEN1 nuclear interacting partners in MCF7 breast cancer cell nuclei in order to the identifiy new possible therapeutic targets for a more effective pharmacological treatment of endocrine therapy-resistant tumors.

Genome-wide activity of unliganded Estrogen Receptor alpha in breast cancer cells [RNA-Seq]

Project description:ERα is essential for the anti-proliferative response of breast cancer cells not only to estrogen antagonists, but also to estrogen withdrawal by means of aromatase inhibitors. We explored here one of the simplest explanation for this, consisting in the possibility that ERα may have a wide genomic function in absence of ligands. The genomic binding of ERα in the complete absence of estrogen was then studied using hormone-dependent MCF7 cells, by chromatin immunoprecipitation sequencing. From these data, 4.2K highly significant binding events were identified, which were further confirmed by comparing binding events in cells expressing ERα to cells silenced for ERα. Apo-ERα binding sites were distributed close to genes with functions associated to cell growth and epithelial maintenance and show significant overlap with binding of other transcription factors important for luminal epithelial breast cancer. Interestingly, we found that upon ERα silencing cognate gene transcription in absence of estrogen is downregulated and this is accompanied by increased H27Kme3 at ERα binding sites. RNA-Seq experiments showed that unliganded ERα controls basal transcription widely, including both coding and noncoding transcripts. Genes affected by ERα silencing can be easily functionally related to mammary epithelium differentiation and maintenance, especially when considering downregulated genes. Additional functions related to inflammatory and immune response was observed. Our data unravel unexpected actions of ERα in breast cancer cells and provide a novel framework to understand success and failure of hormone therapy in breast cancer. Examination of unligandend estrogen receptor alpha (aERα) DNA interactions in control and aERα siRNA treated MCF7 cells.

Proteasome inhibition blocks estrogen-dependent gene transcription by decreasing histone H2B monoubiquitination in human breast cancer cells

Project description:The estrogen receptor-alpha (ERα) determines breast cancer cell phenotype and is a prognostic indicator. A better understanding of the mechanisms controlling ERα function may uncover improved strategies for the treatment of breast cancer. Proteasome inhibition was previously reported to regulate estrogen-induced transcription but the mechanisms by which it influences ERα function remain controversial. In this study we investigated the transcriptome-wide effects of the proteasome inhibitor Velcade on estrogen-regulated transcription in MCF7 human breast cancer cells and demonstrate a specific global decrease in estrogen-induced transcription. This set contains 12 microarray samples. 3 controls, 3 estrogen stimulated, 3 Bortezomib stimulated, 3 Bortezomib + estrogen stimulated

Bromodomain protein BRD4 is required for estrogen receptor-dependent transcription and enhancer activation [ChIP-seq]

Project description:The estrogen receptor-α (ERα) is a transcription factor which plays a critical role in controlling cell proliferation and tumorigenesis by recruiting various cofactors to estrogen response elements (EREs) to induce or repress gene transcription. A deeper understanding of these transcriptional mechanisms may uncover novel therapeutic targets for ERα-dependent cancers. Here we show for the first time that BRD4 regulates ERα−induced gene expression by affecting elongation-associated phosphorylation of RNA Polymerase II (RNAPII P-Ser2) and histone H2B monoubiquitination (H2Bub1). Consistently, BRD4 activity is required for estrogen-induced proliferation of ER+ breast and endometrial cancer cells and uterine growth in mice. Genome-wide occupancy studies revealed an enrichment of BRD4 on transcriptional start sites as well as EREs enriched for H3K27ac and demonstrate a requirement for BRD4 for H2B monoubiquitination in the transcribed region of estrogen-responsive genes. Importantly, we further demonstrate that BRD4 occupancy correlates with active mRNA transcription and is required for the production of ERα-dependent enhancer RNAs (eRNAs). These results uncover BRD4 as a central regulator of ERα function and potential therapeutic target. ChIP-sequencing of BRD4, ERα and H2Bub1 in MCF7 cells treated with +/- estrogen treatment and or +/- JQ1 treatment in triplicates.
