Expression of DOG1, CD117 and PDGFRA in gastrointestinal stromal tumors and correlations with clinicopathology.
OBJECTIVE To discuss the significance of DOG1, CD117 and PDGFRA in the diagnosis of gastrointestinal stromal tumors (GISTs), and analyze their correlations with clinicopathological features and risk ranking. METHOD DOG1, CD117 and PDGFRA were detected with IHC Envision ldpe-g-nvp in 63 GISTs and 43 cases of non-GISTs, and analyzed for relations with clinicopathological factors (gender, age, l...
متن کاملExpression of DOG1, PDGFRA, and p16 in Gastrointestinal Stromal Tumors
BACKGROUND/AIMS The diagnosis of gastrointestinal stromal tumors (GIST) relies on the demonstration of KIT expression, but KIT expression is absent or reduced in approximately 15% of GIST. METHODS Eighty-one GISTs were diagnosed between January 1998 and December 2007 at the Department of Pathology at both Chungnam National University Hospital and Eulji University Hospital, Daejeon. Medical hi...
متن کاملPresence of PDGFRA and DOG1 mutations in gastrointestinal stromal tumors among Chinese population.
Approximately 15% of gastrointestinal stromal tumors (GIST) do not express KIT mutations and of these about 5 to 7% harbor mutations in PDGFRA. DOG1 was specifically expressed in GISTs. These cases require special attention for PDGFRA and DOG1 mutational status. Hundred cases of GIST were diagnosed between August 2007 and October 2012 at the First Affiliated Hospital of Guangxi Medical Universi...
متن کاملDOG1 regulates growth and IGFBP5 in gastrointestinal stromal tumors.
Gastrointestinal stromal tumors (GIST) are characterized by activating mutations of KIT or platelet-derived growth factor receptor α(PDGFRA), which can be therapeutically targeted by tyrosine kinase inhibitors (TKI) such as imatinib. Despite long-lasting responses, most patients eventually progress after TKI therapy. The calcium-dependent chloride channel DOG1 (ANO1/TMEM16A), which is strongly ...
