Simple Summary: This review provides an in depth analysis of the role of bromodomain-containing proteins in cancer development. As readers of acetylated lysine on nucleosomal histones, bromod- omain proteins are poised to activate gene expression, and often promote cancer progression. We examined changes in gene expression patterns that are observed in bromodomain-containing proteins and associated with specific cancer types. We also mapped the protein–protein interaction network for the human bromodomain-containing proteins, discuss the cellular roles of these epigenetic regu- lators as part of nine different functional groups, and identify bromodomain-specific mechanisms in cancer development. Lastly, we summarize emerging strategies to target bromodomain proteins in cancer therapy, including those that may be essential for overcoming resistance. Overall, this review provides a timely discussion of the different mechanisms of bromodomain-containing pro- Citation: Boyson, S.P.; Gao, C.; teins in cancer, and an updated assessment of their utility as a therapeutic target for a variety of Quinn, K.; Boyd, J.; Paculova, H.; cancer subtypes. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -
Multiple Cellular Proteins Interact with LEDGF/P75 Through a Conserved Unstructured Consensus Motif
ARTICLE Received 19 Jan 2015 | Accepted 1 Jul 2015 | Published 6 Aug 2015 DOI: 10.1038/ncomms8968 Multiple cellular proteins interact with LEDGF/p75 through a conserved unstructured consensus motif Petr Tesina1,2,3,*, Katerˇina Cˇerma´kova´4,*, Magdalena Horˇejsˇ´ı3, Katerˇina Procha´zkova´1, Milan Fa´bry3, Subhalakshmi Sharma4, Frauke Christ4, Jonas Demeulemeester4, Zeger Debyser4, Jan De Rijck4,**, Va´clav Veverka1,** & Pavlı´na Rˇeza´cˇova´1,3,** Lens epithelium-derived growth factor (LEDGF/p75) is an epigenetic reader and attractive therapeutic target involved in HIV integration and the development of mixed lineage leukaemia (MLL1) fusion-driven leukaemia. Besides HIV integrase and the MLL1-menin complex, LEDGF/p75 interacts with various cellular proteins via its integrase binding domain (IBD). Here we present structural characterization of IBD interactions with transcriptional repressor JPO2 and domesticated transposase PogZ, and show that the PogZ interaction is nearly identical to the interaction of LEDGF/p75 with MLL1. The interaction with the IBD is maintained by an intrinsically disordered IBD-binding motif (IBM) common to all known cellular partners of LEDGF/p75. In addition, based on IBM conservation, we identify and validate IWS1 as a novel LEDGF/p75 interaction partner. Our results also reveal how HIV integrase efficiently displaces cellular binding partners from LEDGF/p75. Finally, the similar binding modes of LEDGF/p75 interaction partners represent a new challenge for the development of selective interaction inhibitors. 1 Institute of Organic Chemistry and Biochemistry of the ASCR, v.v.i., Flemingovo nam. 2, 166 10 Prague, Czech Republic. 2 Department of Genetics and Microbiology, Faculty of Science, Charles University in Prague, Vinicna 5, 128 44 Prague, Czech Republic. -

SMARCA5 transcriptionally inhibits the myeloid master regulator PU.1. Upregulation of SMARCA5 was previously observed in CD34+ hematopoietic progenitors of acute myeloid leukemia (AML) patients. Since high levels of SMARCA5 are necessary for intensive cell proliferation and cell cycle progression of developing hematopoietic stem and progenitor cells in mice, we reasoned that removal of SMARCA5 enzymatic activity could affect the cycling or undifferentiated state of leukemic progenitor-like clones. -

The 5’ external transcribed spacer (5' ETS) is the most prominent one that recruits U3 snoRNA and a plethora of proteins during the early assembly of 90S small subunit pre-ribosomes. Here, we have conducted a comprehensive mutational analysis of 5' ETS by monitoring the processing and assembly of a plasmid-expressed pre-18S RNA. Remarkably, nearly half of the 5' ETS sequences, when depleted individually, are dispensable for 18S rRNA processing. The dispensable elements largely bind at the surface of 90S structure. Defective assembly of 5' ETS completely blocks the last stage of 90S formation, yet has little effect on the early assembly of 5' and central domain of 18S rRNA. Our study reveals the functional regions of 5' ETS and provides new insight into the assembly hierarchy of 90S pre-ribosomes.
