Project description:This SuperSeries is composed of the following subset Series: GSE33437: NDRG1 siRNA and overexpression in breast cell lines GSE33438: MCF-7 and ZR-75-1 cell lines hypoxia Refer to individual Series
Project description:We performed RNA-sequencing on 7 tamoxifen-resistant (MCF-7 Tam1, T-47D Tam1, T-47D Tam2, ZR-75-1 Tam1, ZR-75-1 Tam2, BT474 Tam1 and BT-474 Tam2) and their isogenic parental (MCF-7, T-47D, ZR-75-1 and BT-474) breast cancer cell lines. The tamoxifen-resistant cell lines were generated from the parentel cell lines by continuous administration of 1 µM 4-OH-tamoxifen for eight to twelve months. RNA- sequencing was performed to determine the changes in the expression of genes in the resistant clones as well as pathways. In addition, we compared the expression changes of the cell lines with those of the GSE58708 data set which we reanalyzied in our pipeline.
Project description:To determine the miRNAs’ roles in the tumorigenesis behavior of TNBC, we profiled the global miRNA expression in 2 highly aggressive TNBC cell lines (MDA-MB-231 and CAL-51) in comparison with that in 2 non-aggressive luminal-type breast cancer cell lines (ZR-75-1 and MCF-7).
Project description:Time course of response to synthetic progestin ORG2058 in T-47D and ZR-75-1 breast cancer cell lines and in two PR positive clones of the MCF-10A cell line: AB9 and AB32. Transcriptional response to synthetic progestin, 10nM ORG2058, was compared between the four cell lines at three treatment times.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:In order to study transcriptional heterogeneity in response to hormone stimulation in breast cancer, we performed high-throughput single-cell RNA sequencing (scRNA-seq) on 3 breast cancer cell lines that differ in their nuclear receptor expression levels. MCF-7, T-47D and ZR-75-1 cell lines were treated with estrogen and progesterone alone or in combination and collected at different time points. Hash-tagging antibodies were used to identify samples.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression. Two-condition experiment, Normoxic MSCs vs. Hypoxic MSCs.
Project description:Time course of response to synthetic progestin ORG2058 in T-47D and ZR-75-1 breast cancer cell lines and in two PR positive clones of the MCF-10A cell line: AB9 and AB32. Transcriptional response to synthetic progestin, 10nM ORG2058, was compared between the four cell lines at three treatment times. T-47D breast cancer cells were treated in triplicate with 10nM ORG2058 or ethanol vehicle and harvested at 2, 6 and 24h after treatment for gene expression profiling
