Knockdown of EI24 in ZR-75-1 cells

ABSTRACT: Analysis of ZR-75-1 cells folowing knockdown of EI24 (P53-Induced Gene 8) and control vector. As a p53 response gene, EI24 is known to controlling cell growth, apoptosis, and autophagy. Results provide insight into the role of EI24 in epithelial-to-mesenchymal Parental ZR-75-1 cells, ZR-75-1 cells with shGFP knockdown (control), Two independent clone of knockdown of EI24 in ZR-75-1. All samples are perfomed in duplicate. Total 8 samples exist.

ZR-75-1 microarray expression data

Project description:Testing the hormonal response of ZR-75-1 cells to estrogen, androgens, and a combination of both homones, with view determining the crosstalk between the transcriptional programs mediated by these hormones in breast cancer cells, and comparison with matched ChIP sequencing data for AR and ERalpha. Data analysis demonstrated reciprocal interference between 5α-dihydrotestosterone (DHT)- and estradiol (E2)-induced transcriptional programs. Specifically, regulation of 26% of E2 and 15% of DHT target genes was significantly affected by cotreatment with the other hormone, in the majority of cases (78-83%) antagonistically. Pathway analysis suggested that DHT co-treatment, for example, depleted E2-regulted pathways in cell survival and proliferation. Total RNA was extractd from luminal-like breast cancer ZR-75-1 cells in quadruplicate after treatment for 16h with 10nM of E2, DHT or E2+DHT.

Targets of CDK12 on ZR-75-30 breast cancer cells (RNA-seq)

Project description:RNA-sequencing analysis of CDK12 overexpressiong ZR-75-30 cell lines. Cyclin dependent kinase 12 (CDK12) is amplified in approximately 70-90% of HER2 amplified breast cancer. Results provide insight into the targets of CDK12 in HER2 positive breast cancer.

Estrogen priming of breast cancer ZR-75-1 cells results in a unique response to a timecourse of progesterone and medroxyprogesterone acetate exposure

Project description:A timecourse assessment of the response of ZR-75-1 breast cancer cells to progestogens in cells pretreated with estrogen. P4 treatment in cells pretreated with E2 results in a unique transcriptional response, including upregulation of ErbB growth factor pathways and alteration of the intrinsic subtype of the breast cancer cells.

MCF-7 and ZR-75-1 cell lines hypoxia

Project description:N-myc downstream-regulated gene 1 (*NDRG1*) is induced by cellular stress such as hypoxia and DNA damage, and in humans, germ line mutations cause Charcot-Marie-Tooth disease. However, the roles of NDRG1 in the cell are not fully understood. Previously, NDRG1 was shown to mediate doxorubicin resistance under hypoxia, suggesting a role for NDRG1 in cell survival under these conditions. We found decreased apoptosis in doxorubicin-treated cells expressing NDRG1 shRNAs under normoxia, demonstrating a requirement for NDRG1 in apoptosis in breast epithelial cells under normal oxygen pressure. We further compared expression profiles in human breast epithelial cells ectopically over-expressing NDRG1 with cells expressing NDRG1 shRNAs in order to identify biological pathways where NDRG1 is involved. The results suggest that NDRG1 may have roles connected to vesicle transport. The previously reported roles of NDRG1 in apoptosis, myelin sheet maintenance, enhanced exocytosis in mast cells and in cellular responses to hypoxia, heavy metals, and androgen may all converge by NDRG1 having a role linked to vesicle transport. Two condition design, MCF-7 and ZR-75-1 cell lines grown in hypoxia compared to cells grown at normoxia.

Restoring miR-150-5p to an estrogen receptor positive breast cancer cell line [ZR-75-1]

Project description:The objective of these experiments is to identify novel direct and indirect targets of miR-150-5p in breast cancer cell lines. The goal is that these will give direction as to what targets or pathways may be contributing to the reduced growth observed in these cell lines upon restoration of miR-150-5p. A therapy directed towards one or more critical subtype-specific targets could be developed as a therapeutic for breast cancer patients. Using has-miR-150-5p mirVana miRNA mimic (Ambion, 4464066), miR-150-5p was restored to an estrogen receptor positive breast cancer cell line, ZR-75-1.
