TranscriptomicsLow-dose actinomycin D preferentially disrupts EWS-FLI1DNA binding.
Fusion of the EWS gene to FLI1 produces a fusion oncoprotein that drives an aberrant gene expression program responsible for the development of Ewing sarcoma. We used a homogenous proximity assay to screen for compounds that disrupt the binding of EWS-FLI1 to its cognate DNA targets. A number of DNA...

TranscriptomicsTargeted disruption of the BCL9/beta-catenin complex in cancer
Stabilized Alpha-Helix peptides of BCL9 HD2 (SAH-BCL9) block BCL9 and B9L interactions with beta-catenin and specifically downregulate Wnt target gene expression. RNA from triplicate SAH-BCL9B- and vehicle-treated DLD1 samples (10 µM each for 12 hours) was hybridized to Affymetrix Human U133 Plus 2....

TranscriptomicsSmall-molecule inhibitor JQ1 effect on multiple myeloma cell lines
Pathologic activation of c-Myc plays a central role in pathogenesis of several neoplasias, including multiple myeloma. However, therapeutic targeting of c-Myc has remained elusive due to its lack of a clear ligand-binding domain. We therefore targeted c-Myc transcriptional function by another means,...

TranscriptomicsNSD3-NUT Fusion Oncoprotein in NUT Midline Carcinoma identified in 1221 patient-derived cell line by RNA-seq
Discarded live tumor tissue from a metastatic focus in the patientM-bM-^@M-^Ys lung was collected under institutional review board approval through the NUT midline carcinoma registry (www.NMCRegistry.org). From this tissue the first known NUT-variant cell line, 1221, was established. To determine th...

GenomicsH3K9/14Ac in TC-797 genome
The goal is to localize "active" histone marks known to bind BRD4-NUT in the NMC genome. Characterization of the reference epigenome in humans by use of ChIP-Seq in the TC-797 human NMC cell line. ChIP-seq of untreated TC-797 cells using H3K9/14Ac antibodies versus IgG control.

TranscriptomicsBET Bromodomains Mediate Transcriptional Pause Release in Heart Failure [NRVM Expression]
Heart failure (HF) is driven via interplay between master regulatory transcription factors and dynamic alterations in chromatin structure. While pathologic gene transactivation in this context is known to be associated with recruitment of histone acetyl-transferases and local chromatin hyperacetylat...
