Expression data from JQ1 (0.2 uM) treated tamoxifen-resistant MCF7 cells

ABSTRACT: Estrogen signaling pathway is critical for breast cancer development and has remained the major adjuvant therapeutic target for this disease. Tamoxifen has been used in clinic for many years to treat ER-positive breast cancer. However a great many (30%) suffer relapse due to drug resistance. In this study, the bromodomain inhibitor JQ1 was found to down-regulate ERalpha gene expression and have anti-tumor effect in cultured tamoxifen-resisant breast cancer cells. We used microarrays to detail the global programme of gene expression in tamoxifen-resistant MCF7 cells treated with the bromodomain inhibitor JQ1.

We used microarrays to detail the global programme of gene expression in tamoxifen-resistant MCF7 cells treated with the bromodomain inhibitor JQ1. Tamoxifen-resistant breast cancer MCF7 cells were treated with DMSO (vehicle) or JQ1 (0.2 uM) for 24 hours before total RNA was purified for microarray. Each sample was triplicated.

Gene expression change after JQ1 treatment in breast cancer cell

Project description:BET bromodomain inhibitors effectively kill several types of cancer cells. However, the underlying mechanism of BET inhibition resistance remains obscure. We sought to identify the gene expression change upon treatment of JQ1, a well-known BET inhibitor, in basal-like breast cancer cells. In this dataset, we used RNA-sequencing to characterize the mRNA expression profiles from DMSO and JQ1-treated MDA-MB-231 breast tumor cells.

Differential gene expression in neuroblastoma cells after treatment with JQ1, nanaomycin, or combination of JQ1 and nanaomycin

Project description:BET bromodomain inhibitors are emerging as very promising novel anticancer agents. Combination of BET bromodomain inhibitor JQ1 and quinone-containing compound nanaomycin exerts synergistic anticancer effect in neuroblastoma We analysed whether a treatment with BET bromodomain inhibitor JQ1, and quinone-containing compound Nanaomycin synergistically modulate gene expression

Differential gene expression in neuroblastoma cells after treatment with vehicle control, JQ1, panobinostat, or combination of JQ1 and panobinostat

Project description:The bromodomain inhibitor JQ1 and the histone deacetylase inhibitor panobinostat induce synergistic anticancer effects We analyzed whether JQ1 and panobinostat synergistically modulate gene expression Neuroblastoma SK-N-BE(2) cells were treated with vehicle control, 1 microM JQ1, 10 nM panobinostat, or combination of JQ1 and panobinostat for 6 hours, and subjected to differential gene expression studies with Affymetrix microarrays.

Gene expression profiling of MYC-amplified medulloblastoma cell lines treated by JQ1, a BET bromodomain inhibitor

Project description:MYC-amplified medulloblastomas are highly lethal tumors. BET bromodomain inhibition was recently described to downregulate MYC-associated transcriptional activity in various cancer subtypes. To investigate whether JQ1, a BET bromodomain inhibitor is downregulation MYC and MYC-associated transcriptional activity, we performed global gene expression profiling of five medulloblastomas MYC-amplified patient-derived cell lines treated by JQ1 and the inactive form of JQ1. Five medulloblastomas patient-derived MYC-amplified cell lines were treated with the active and the inactive form of the drug (JQ1S or JQ1R, respectively, 1μM for 24 hours) followed by RNA extraction and hybridization on Affymetrix microarrays

Response of triple negative breast cancer to BAZ2A/B inhibition and BET bromodomain inhibition alone and in combination (ChIPseq)

Project description:Three triple negative breast cancer cell lines (MDAMB231, SUM159, and HCC1806) were treated with small molecule inhibitors (JQ1, BET bromodomain inhibitor; GSK2801, BAZ2A/B bromodomain inhibitor) or BAZ siRNA alone and in combination with JQ1 for 48 hours
