Description
Bromodomain and extra-terminal (BET) family proteins are key regulators of gene expression in cancer. Herein, we utilize BRD4 profiling to identify critical pathways involved in pathogenesis of chronic lymphocytic leukemia (CLL). BRD4 is over-expressed in CLL and is enriched proximal to genes up-regulated or de novo expressed in CLL with known function in disease pathogenesis and progression. These genes, including key members of the BCR signaling pathway, provide rationale for this therapeutic approach to identify new targets in alternative types of cancer. Additionally, we describe PLX51107, a structurally distinct BET inhibitor with novel in vitro and in vivo pharmacologic properties that emulates or exceeds the efficacy of BCR signaling agents in pre-clinical models of CLL. Herein, the discovery of the involvement of BRD4 in the core CLL transcriptional program provides a compelling rationale for clinical investigation of PLX51107 as epigenetic therapy in CLL and application of BRD4 profiling in other cancers.

Description
Oral squamous cell carcinoma (OSCC) is a prevalent form of cancer that develops from the epithelium of the oral cavity. OSCC is on the rise worldwide, and death rates associated with the disease are particularly high. Despite progress in understanding of the mutational and expression landscape associated with OSCC, advances in deciphering these alterations for the development of therapeutic strategies have been limited. Further insight into the molecular cues that contribute to OSCC is therefore required. Here we show that the transcriptional regulators YAP (YAP1) and TAZ (WWTR1), which are key effectors of the Hippo pathway, drive pro-tumorigenic signals in OSCC. Regions of pre-malignant oral tissues exhibit aberrant nuclear YAP accumulation, suggesting that dysregulated YAP activity contributes to the onset of OSCC. Supporting this premise, we determined that nuclear YAP and TAZ activity drives OSCC cell proliferation, survival, and migration in vitro, and is required for OSCC tumor growth and metastasis in vivo. Global gene expression profiles associated with YAP and TAZ knockdown revealed changes in the control of gene expression implicated in pro-tumorigenic signaling, including those required for cell cycle progression and survival. Notably, the transcriptional signature regulated by YAP and TAZ significantly correlates with gene expression changes occurring in human OSCCs identified by The Cancer Genome Atlas (TCGA), emphasizing a central role for YAP and TAZ in OSCC biology.

Description
PTBA has been published to increase renal tubular cell proliferation, increased survival, and increased renal functional recovery in fish and various models of murine models of acute kidney injury. Immunohistological analyses suggested increased cell proliferation is accompanied by increased epithelial-to-mesenchymal transition in the RTECs. In order to elucidate pathways responsible for the increased repair response after compound treatment, larval zebrafish were given AKI and treated with PTBA analogue, UPHD25 or DMSO. Results suggests that epithelial-related genes were downregulated while mesenchymal-related genes were upregulated with injury and compound treatment. Results further validate our immunohistological finding that our compound increase post-AKI repair by increasing EMT in renal tubular cells. Overall design: At 3dpf, larval zebrafish are given acute kidney injury with gentamicin microinjection. 2 days post injury, larvae with AKI are selected and treated with 1uM of PTBA analogue, UPHD25 or vehicle control, 1% DMSO. The fish were treated with UPHD25 or DMSO for 24 hours. Then, pronephric kidneys were collected using DDT, collagenase I, and manual collection. Total 100 larvae were collected per sample, per replicate. Each treatment group was repeated with 3 biological replicates. RNA was collected and sequenced.

Description
We screened SLE monocytes from 19 SLE patients and selected 4 that induced CD4+ T cell proliferation in vitro and 4 that did not. CFSE labeled CD4-T cells (105) were incubated with SLE monocytes (2 x 104). Cells were harvested at 6 hours for RNA extraction.

Description
To explore the full extent of IFN-regulated transcriptional changes, we exposed monocytes from two healthy donors to recombinant type I IFN (IFN-2b) in vitro. RNA was extracted at different incubation times (1, 6, 24, 48 and 72 hrs) and the expression data was normalized to that of monocytes cultured with medium.

Description
To directly compare the SLE monocyte transcriptional program with that of blood mDC precursors, we purified lineage HLA-DRhighCD11chigh mDCs and CD14+ monocytes from the blood of five healthy donors. Their gene expression profiles were then compared to those of blood SLE monocytes. An unsupervised clustering analysis of transcripts present in >20% of the samples classified healthy monocytes, SLE monocytes and healthy mDCs into three well defined groups. A supervised analysis was then performed to find genes: 1) differentially expressed in healthy mDCs compared to monocytes; 2) shared by healthy blood mDCs and SLE blood monocytes.
