ETV1 is highly expressed in GIST cells and required for their survival and growth. To identify genes and pathways regulated by ETV1 in GIST, we performed expression profiles of GIST cells after ETV1 knockdown. Two GIST cell lines (GIST48 and GIST882) were infected in duplicate with three shRNA virus...

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 ...

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 defi...

Leiomyosarcoma (LMS) is a malignant neoplasm with smooth muscle differentiation. Little is known about its molecular heterogeneity and no targeted therapy currently exists for LMS. We demonstrate the existence of 3 molecular subtypes in a cohort of 99 cases and an independent cohort of 82 LMS. Tw...
