Expression Data from Gastrointestinal Stromal Tumor (GIST) Cell Lines

Project description: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. The combination of KIT and FGFR inhibition showed increased growth inhibition in imatinib-sensitive GIST cell lines in the presence or absence of added FGF2 in vitro, and delayed tumor regrowth in vivo. In addition, inhibition of mitogen-activated protein kinase (MAPK) signaling by imatinib was not sustained in GIST cells. An extracellular signal-regulated kinase (ERK) rebound occurred through activation of FGF signaling, and was repressed by FGFR1 inhibition. Downregultation of Sprouty proteins played a role in the imatinib-induced feedback activation of FGF signaling in GIST cells. We used micorarrays to quantify the gene expression levels in GIST cell lines.

Distinct gene-expression-defined classes of gastrointestinal stromal tumor (GIST).

Project description:GIST is considered to invariably arise through gain-of-function KIT or PDGFRA mutation of the interstitial cells of Cajal (ICC). However, the genetic basis of the malignant progression of GIST is poorly understood. We analysed the expression levels of 54,613 probe sets in 32 surgical samples of untreated GIST of the stomach and small intestine with GeneChip Human Genome U133 Plus 2.0 arrays. Keywords: gene expression array-based, count

miRNA expression profile in GIST (gastrointestinal stromal tumor)

Project description:To clarify aberrantly expressed miRNAs affecting the biology of GIST, miRNA array was performed in 19 cases of GIST. A series of 19 GISTs specimens were analyzed using 3D-Gene Human miRNA Oligo chips containing 904 human miRNAs and 107 viral miRNAs anti-sense probes printed in duplicate spots (Toray, Kamakura, Japan).
