Description
Acquired drug resistance prevents targeted cancer therapy from achieving stable and complete responses. Emerging evidence implicates a key role for nonmutational mechanisms including changes in cell state during early stages of acquired drug resistance. Targeting nonmutational resistance may therefore present a therapeutic opportunity to eliminate residual surviving tumor cells and impede relapse. A variety of cancer cell lines harbor quiescent, reversibly drug-tolerant “persister” cells which survive cytotoxic drugs including targeted therapies and chemotherapies. These persister cells survive drug through nonmutational mechanisms which are poorly understood. Specifically targeting persister cells is a promising strategy to prevent tumor relapse. We sought to identify therapeutically exploitable vulnerabilities in persister cells using the HER2-amplified breast cancer line BT474 as an experimental model. Similar to other persister cell models, upon treatment with the HER2 inhibitor lapatinib (2uM concentration) for nine or more days, the majority of BT474 cells die, revealing a small population of quiescent surviving persister cells. Removal of lapatinib allows the persister cells to regrow and to re-acquire sensitivity to lapatinib. Subsequent lapatinib treatment re-derives persister cells. The reversibility of persister cell drug resistance indicates a nonmutational resistance mechanism. Here we provide RNAseq gene expression profiling data generated from parental BT474 cells compared to BT474 persister cells generated from nine days of treatment with 2 uM lapatinib. These data can be used to identify genes and pathways which are upregulated in persister cells, revealing potential therapeutic targets. Overall design: 3 biological replicates of BT474 persister cells, two biological replicates of BT474 parental cells

Description
We performed RNA-Seq analysis of wildtype and three EPAS1-/- 786-O single cell clones generated by CRISPR/Cas9 to identify the HIF-2a-responsive genes in this cell line. Samples from wildtype 786-O cells treated with DMSO or HIF-2a antagonist compound C2 were also included in this analysis. Overall design: In this experiment, we analyzed the transcriptomic profiles of 2 replicates of wildtype (WT) EPAS1+/+ 786-O cells, 1 replicate for each of the three independent EPAS1-/- 786-O single cell clones, 1 replicate of WT-786-O cells treated with DMSO and 1 replicate of WT-786-O cells treated with 10uM HIF-2a antagonist C2.

Description
We examined the transcriptional changes modulated by KDM1A inhibitor NCD-38 by performing global transcriptome analysis. Glioma Stem Cells (GSC10) were treated with either vehicle or NCD-38 for 24 h and the isolated RNA was utilized for RNA-seq analysis. Our results demonstrated that NCD-38 modulated several genes that are involved in unfolded protein response, endoplasmic reticulum stress pathway and NRF-2 mediated oxidative stress response. Overall design: Total RNA was isolated from the GSC10 cells that were treated with vehicle or NCD-38 for 24 hours. Illumina TruSeq RNA Sample Preparation was performed following manufacturer''s protocol. Samples were run on an Illumina HiSeq 2000 in duplicate. The combined raw reads were aligned to UCSC hg19 and genes were annotated by Tophat. Genes were annotated and quantified by HTSeq-DESeq pipeline.

We examined the transcriptional changes modulated by estrogen receptor beta (ERß) by performing global transcriptome analysis. U87 cells were transduced with lentiviral particles carrying either empty vector or ERß-FLAG expression vector and the RNA was isolated and utilized for RNA-seq analysis. Our results demonstrated that ERß modulated genes were related to homologous recombination, DNA damage response, ATM signaling and cell cycle pathways. Overall design: Total RNA was isolated from U87 cells expressing either empty vector or ERß expression vector. Illumina TruSeq RNA Sample Preparation was performed following manufacturer's protocol.
