Publication Genomic discovery and clonal tracking in multiple myeloma by cell free DNA sequencing(Nature Publishing Group, 2018) Guo, Guangwu; Raje, Noopur; Seifer, Charles; Kloeber, Jake; Meyerson, Matthew; Munshi, Nikhil; Knoechel, Birgit; Lohr, JensPublication An oncogenic MYB feedback loop drives alternate cell fates in adenoid cystic carcinoma(2016) Drier, Yotam; Cotton, Matthew J.; Williamson, Kaylyn; Gillespie, Shawn M.; Ryan, Russell J.H.; Kluk, Michael J.; Carey, Christopher D.; Rodig, Scott; Sholl, Lynette; Afrogheh, Amir H.; Faquin, William; Queimado, Lurdes; Qi, Jun; Wick, Michael J.; El-Naggar, Adel K.; Bradner, James E; Moskaluk, Christopher A.; Aster, Jon; Knoechel, Birgit; Bernstein, BradleyTranslocation events are frequent in cancer and may create chimeric fusions or ‘regulatory rearrangements’ that drive oncogene overexpression. Here we identify super-enhancer translocations that drive overexpression of the oncogenic transcription factor MYB as a recurrent theme in adenoid cystic carcinoma (ACC). Whole-genome sequencing data and chromatin maps reveal distinct chromosomal rearrangements that juxtapose super-enhancers to the MYB locus. Chromosome conformation capture confirms that the translocated enhancers interact with the MYB promoter. Remarkably, MYB protein binds to the translocated enhancers, creating a positive feedback loop that sustains its expression. MYB also binds enhancers that drive different regulatory programs in alternate cell lineages in ACC, cooperating with TP63 in myoepithelial cells and a Notch program in luminal epithelial cells. Bromodomain inhibitors slow tumor growth in ACC primagraft models in vivo. Thus, our study identifies super-enhancer translocations that drive MYB expression and provides insight into downstream MYB functions in the alternate ACC lineages.Publication Dynamic Transcriptional Reprogramming Leads to Immunotherapeutic Vulnerabilities in Myeloma(Springer Science and Business Media LLC, 2021-10-21) Frede, Julia; Anand, Praveen; Sotudeh, Noori; Pinto, Ricardo A.; Nair, Monica S.; Stuart, Hannah; Yee, Andrew J.; Vijaykumar, Tushara; Waldschmidt, Johannes M.; Potdar, Sayalee; Kloeber, Jake A.; Kokkalis, Antonis; Dimitrova, Valeriya; Mann, Mason; Laubach, Jacob; Richardson, Paul; Anderson, Kenneth; Raje, Noopur; Knoechel, Birgit; Lohr, Jens
