Description
E47 is a basic Helix Loop Helix (bHLH) transcription factor that has important roles in cell fate determination and differentiation of many cell types. In the nervous system E47 heterodimerizes with tissue-specific, pro-neural bHLH transcription factors and activates downstream target genes. To identify the relevant target genes of bHLH transcription factors in neural cells, we performed gene expression profiling of the human neuroblastoma cell line SK-N-SH engineered to acutely express ectopic E47 by an adenoviral vector. The experiments were done at two time points following adenoviral infection, 8 hours and 20 hours. Genes induced by E47 after 8 hours are likely to be direct targets of this transcription factor.

Description
We developed a general approach to small molecule library screening called GE-HTS (Gene Expression-Based High Throughput Screening) in which a gene expression signature is used as a surrogate for cellular states and applied it to the identification of compounds inducing the differentiation of acute myeloid leukemia cells. In screening 1,739 compounds, we identified 8 that reliably induced the differentiation signature, and furthermore yielded functional evidence of bona fide differentiation.

Description
We developed a general approach to small molecule library screening called GE-HTS (Gene Expression-Based High Throughput Screening) in which a gene expression signature is used as a surrogate for cellular states and applied it to the identification of compounds inducing the differentiation of acute myeloid leukemia cells. In screening 1,739 compounds, we prioritized 15 candidate compounds (2 were already confirmed in the literature). We next evaluated the 13 remaining compounds. Eight reliably induced the differentiation signature, and furthermore yielded functional evidence of bona fide differentiation.

Description
Cure rates for patients with acute myeloid leukemia (AML) remain low despite ever-increasing dose intensity of cytotoxic therapy. In an effort to identify novel approaches to AML therapy, we recently reported a new method of chemical screening based on the modulation of a gene expression signature of interest. We applied this approach to the discovery of AML-differentiation-promoting compounds. Among the compounds inducing neutrophilic differentiation was DAPH1 (4,5-dianilinophthalimide), previously reported to inhibit epidermal growth factor receptor (EGFR) kinase activity. Here we report that the Food and Drug Administration (FDA)-approved EGFR inhibitor gefitinib similarly promotes the differentiation of AML cell lines and primary patient-derived AML blasts in vitro. Gefitinib induced differentiation based on morphologic assessment, nitro-blue tetrazolium reduction, cell-surface markers, genome-wide patterns of gene expression, and inhibition of proliferation at clinically achievable doses. Importantly, EGFR expression was not detected in AML cells, indicating that gefitinib functions through a previously unrecognized EGFR-independent mechanism. These studies indicate that clinical trials testing the efficacy of gefitinib in patients with AML are warranted.

In screening 1,739 compounds, we identified 8 that reliably induced the differentiation signature, and furthermore yielded functional evidence of bona fide differentiation. We tested several of these in duplicate replicates in blasts from a patient with APL. Also included in this data set are a collection of 6 primary patient AML cells, 3 normal neutrophils samples, and 3 normal monocyte samples. This data was used to evaluate whole genome effects of the compounds on APL cells in relation to AML versus normal neutrophils and monocytes.

We sorted Eomes-negative NK cells (CD3- CD56+ CXCR6- CD16-) and Eomes-positive NK cells (CD3- CD56+ CXCR6+) from total leukocytes isolated from the perfusion fluid of five healthy human livers destined for transplantation. Total RNA was extracted from sorted cells, cDNA generated and RNASeq performed. Overall design: Examination of mRNA levels in paired Eomes-negative/Eomes-positive NK cells from the same donor.
