Genes & Cancer: The role of FLI-1-EWS, a fusion gene reciprocal to EWS-FLI-1, in Ewing sarcoma

November 7, 2015

David J. Elzi1, Meihua Song1, Peter J. Houghton1,2,3, Yidong Chen1,2,4, and Yuzuru Shiio1,2,5 ABSTRACT Ewing sarcoma is a cancer of the bone and soft tissue in children that is characterized by a chromosomal translocation involving EWS and an Ets family transcription factor, most commonly FLI-1. The EWS-FLI-1 fusion oncogene is widely believed to play a central […]

Asian Pacific Journal of Cancer Prevention: Mutation Screening and Association Study of the Folylpolyglutamate Synthetase (FPGS) Gene with Susceptibility to Childhood Acute Lymphoblastic Leukemia

November 1, 2015

Duangjai Piwkham 1, Teerapong Siriboonpiputtana, Joke Beuten, Samart Pakakasama, Jonathan Al Gelfond, Karan Paisooksantivatana, Gail E Tomlinson, Budsaba Rerkamnuaychoke Abstract Background: Folylpolyglutamate synthetase (FPGS), an important enzyme in the folate metabolic pathway, plays a central role in the intracellular accumulation of folate and antifolate in several mammalian cell types. Loss of FPGS activity results in decreased cellular levels of antifolates and consequently to polyglutamatable […]

PNAS: Proline-, glutamic acid-, and leucine-rich protein 1 mediates estrogen rapid signaling and neuroprotection in the brain

November 1, 2015

Gangadhara R. Sareddy, Quanguang Zhang, Ruimin Wang, Erin Scott, Yi Zou, Jason C. O’Connor, Yidong Chen, Yan Dong, Ratna K. Vadlamudi, and Darrell Brann Abstract 17-β estradiol (E2) has been implicated as neuroprotective in a variety of neurodegenerative disorders. However, the underlying mechanism remains unknown. Here, we provide genetic evidence, using forebrain-specific knockout (FBKO) mice, that proline-, glutamic acid-, and leucine-rich protein 1 (PELP1), […]

Oncotarget: An mRNA expression signature for prognostication in de novo acute myeloid leukemia patients with normal karyotype

October 23, 2015

Ming-Kai Chuang1,*, Yu-Chiao Chiu2,5,*, Wen-Chien Chou1,3, Hsin-An Hou3, Mei-Hsuan Tseng3, Yi-Yi Kuo1,3, Yidong Chen5,6, Eric Y. Chuang2,4, Hwei-Fang Tien3 ABSTRACT Although clinical features, cytogenetics, and mutations are widely used to predict prognosis in patients with acute myeloid leukemia (AML), further refinement of risk stratification is necessary for optimal treatment, especially in cytogenetically normal (CN) patients.
