TranscriptomicsshRNAi profiling of human MDA-MB-231 cells expressing anti-p53 (shp53) short-hairpin RNAs treated with TFGbeta or control
TGFβ ligands act as tumor suppressors in early stage tumors but are paradoxically diverted into potent prometastatic factors in advanced cancers. The molecular nature of this switch remains enigmatic. We now show that TGFβ-dependent cell migration, invasion and metastasis are empowered by mutant-p...

TranscriptomicsGlucocorticoid and androgen receptor profiling (ChIP-seq) in U2OS-GR and U2OS-AR cells upon hormone treatment
We performed ChIP-seq targeting the glucocorticoid receptor (GR) in the U2OS-GR cell line and the androgen receptor (AR) in the U2OS-AR cell line. The cell lines are derived from U2OS ATTC:HTB-96 and stably transfected with an expression construct for either rat GR or human AR, respectively. The U2O...

TranscriptomicsStudying enhancer activity by FAIRE-STARR-seq in the U2OS-GR and the U2OS-AR cells upon hormone treatment
To quantify functional enhancers, we performed STARR-seq (Self-Transcribing Active Regulatory Region sequencing) in the U2OS-GR and the U2OS-AR cell lines (derived from U2OS ATTC:HTB-96, stably transfected with an expression construct for rat GR or human AR, respectively). U2OS-GR cells were treated...

TranscriptomicsRNA-seq in the U2OS-AR cell line to identify genes regulated by the androgen receptor
To identify the genes regulated by the androgen receptor (AR), we performed RNA-seq in the U2OS-AR cell line (derived from U2OS ATTC:HTB-96, stably transfected with an expression construct for human AR), upon androgen (R1881) or vehicle (DMSO) treatment for 24 hours.

TranscriptomicsGenome-wide profiling of H3K27ac, H3K4me1, H3K27me3 and H3K9me3 (ChIP-seq) in U2OS-GR and U2OS-AR cells
We performed ChIP-seq targeting the H3K27ac, H3K4me1, H3K27me3 and H3K9me3 in the U2OS-GR and U2OS-AR cell lines. The cell lines are derived from U2OS ATTC:HTB-96 and stably transfected with an expression construct for either rat GR or human AR, respectively. The U2OS-GR cells were treated with dexa...

TranscriptomicsATAC-seq in the U2OS-AR cell line comparing cells treated for 4 hours with 5 nM R1881 to vehicle (DMSO) control-treated cells
We performed ATAC-seq in the U2OS-AR cell line (derived from U2OS ATTC:HTB-96, stably transfected with an expression construct for human AR), upon androgen (R1881) or vehicle (DMSO) treatment for 4 hours.

TranscriptomicsEpigenetic events in early breast cancer
Subpopulations of primary Human Mammary Epithelial Cells (HMEC) have the unique ability to escape a period of growth arrest and continue to proliferate. These cells, called post-selection or variant cells (vHMEC), share features with premalignant breast cancer lesions, including p16INK4A promoter h...

Diffuse Intrinsic Pontine Glioma (DIPG) is a fatal brain cancer that arises in the brainstem of children with no effective treatment. To understand what drives DIPGs we integrated whole-genome-sequencing with methylation, expression and copy-number profiling.
