ChIP-Seq of Histone H3K4me1 and H3K4me3 in human GIST48 cells

(Submitter supplied) We previously mapped ETV1 using ChIP-Seq in GIST48 cells (GSE22441). Here, we map the enhancer landscape marked by histone H3K4me1 and the promoter landscape marked by histone H3K4me3 in GIST48 cells.

RNA-Seq of murine GIST-like tumors after Etv1 ablation

(Submitter supplied) We used a mouse expressing three alleles 1) KitV558Delta/+ activating allele that develop GIST-like tumors in the cecum, 2) Etv1 flox/flox conditional knockout allele and 3) Rosa26-CreERT2 tamoxifen activated Cre allele. Mice were treated with either Tamoxifen (to delete Etv1) or corn oil (control). Cecal tumors were isolated for gene expression profiling by RNA-Seq.

Mapping of ETV1 genomic binding sites in gastrointestinal stromal tumor (GIST).

(Submitter supplied) ETV1 is highly expressed in GIST and their presumed precursors--the interstitial cells of Cajal. ETV1 is required for survival for both GIST and ICC and regulates GIST signature genes. Here, using Illumina-Solexa based next-generation sequencing of ETV1 chromatin immunoprecipates (ChIP-Seq), we define ETV1 binding sites in the GIST48 cell line.

Imatinib Treatment of GIST882

(Submitter supplied) Gastrointestinal Stromal Tumor frequently harbor mutations in the KIT receptor tyrosine kinase and depend on its activity for growth. This underlies the efficacy of imatinib, a inhibitor of KIT activity, in GIST management. GIST882 is a patient derived GIST cell line that harbor a K640E exon 13 KIT mutation and is sensitive to imatinib treatment. To analyze the downstream effect of KIT inhibition, GIST882 cells were treated for 8 hours with 1μM Imatinib.

Expression Data from Gastrointestinal Stromal Tumor (GIST) Cell Lines

(Submitter supplied) Activating mutations in either KIT or PDGFRA are present in approximately 90% of gastrointestinal stromal tumors (GISTs). Although treatment with the KIT and PDGFR inhibitor imatinib can control advanced disease in about 80% of GIST patients, the beneficial effect is not durable. Here, we report that ligands from the FGF family reduced the effectiveness of imatinib in GIST cells, and FGF2 and FGFR1 are highly expressed in all primary GIST samples examined. more...

Transcriptome analysis of a FACS-sorted human intersitial cells of Cajal (ICC) [array]

(Submitter supplied) Interstitial cells of Cajal (ICC) are electrical pacemakers and mediators of neuromuscular neurotransmission in the gastrointestinal tract. Gastrointestinal stromal tumors (GIST) arise within the ICC lineage due to activating KIT/PDGFRA mutations. In this study we developed a method for isolation of human ICC by immunolabeling and fluorescence-activated cell sorting (FACS). Briefly, human gastric musculature was dissociated and incubated with antibodies against CD45, FCER1A, CD11B, KIT, and CD34. more...

Enhancer Domains in Gastrointestinal Stromal Tumor Regulate KIT Expression and are Targetable by BET Bromodomain Inhibition [RNA-seq]

(Submitter supplied) Gastrointestinal stromal tumor (GIST) is a mesenchymal neoplasm characterized by activating mutations in the related receptor tyrosine kinases KIT or PDGFRA. GIST relies on expression of these unamplified receptor tyrosine kinase (RTK) genes through a large enhancer domain, producing high expression levels of the oncogene required for tumor growth. Though kinase inhibition is an effective therapy for many GIST patients, disease progression from kinase resistance mutations is common, and no other efficacious classes of systemic therapy exist. more...

FBXO32 is a KIT-downstream prosurvival factor in GIST

(Submitter supplied) GISTs are the most common mesenchymal tumors and they display neuromuscular features. Gain-of-function mutations in KIT or PDGFRA are the initiating event in most of the cases and KIT oncogenic signaling is essential throughout all the disease. Interestingly, KIT oncogenic signaling is driven by PI3K/mTOR and RAS/MAPK pathways regardless of KIT primary or secondary mutations. Hence, dissection of KIT-downstream pathways may result in the identification of novel KIT critical effectors and a new opportunity to overcome disease heterogeneity of resistance mechanisms in GIST. more...

Murine model of gastrointestinal stromal tumors harboring a germline Kit K641E oncogenic mutant

(Submitter supplied) Gastrointestinal stromal tumors (GIST) are thought to derive from the interstitial cells of Cajal (ICC) or an ICC precursor. Oncogenic mutations of the receptor tyrosine kinase KIT are present in most GIST. KIT K642E was originally identified in sporadic GIST and later found in the germ line of a familial GIST. A mouse model of harboring a germline Kit K641E mutant was created to model familial GIST. more...

MOZ and Menin-MLL Complexes are Complementary Regulators of Chromatin Association and Transcriptional Output in Gastrointestinal Stromal Tumor [RNA-seq]

(Submitter supplied) Gastrointestinal stromal tumor (GIST) is commonly characterized by activating mutations in the receptor tyrosine kinase KIT. Tyrosine kinase inhibitors are the only approved therapy for GIST, and other complementary treatment strategies are urgently needed. As GIST both lacks oncogene amplification and relies upon an established network of transcription factors, we hypothesized that unique chromatin modifying enzymes are essential in orchestrating the GIST epigenome. more...
