Ewing sarcoma (EWS) is an aggressive bone tumor of uncertain cellular origin. CD99 is a membrane protein that is expressed in most cases of EWS, although its function in the disease is unknown. Here we have shown that endogenous CD99 expression modulates EWS tumor differentiation and malignancy. We determined that knocking down CD99 expression in human EWS cell lines reduced their ability to fo...
Early warning system (EWS) is a technology to mitigate risk is used to disseminate timely information. Then knowledge management system (KMS) is used to support for decision facilitation will integrate with EWS to disseminate timely information with proactive early warning. Issues on timeliness for timely reporting and decision facilitation are regarded as main challenge for mitigation of risk....
Ewing's sarcoma (ES) is one of the most malignant tumors of bone and soft tissue in children and young adults. ES belongs to a group of small round cell tumors (SRCTs) that also includes neuroblastoma, rhabdomyosarcoma, and malignant lymphoma. However, ES exhibits several specific chimeric genes (EWS-FLI1, EWS-ERG, EWS-ETV1, EWS-E1AF, and EWS-FEV) caused by chromosomal translocations that are n...
Peripheral primitive neuroectodermal tumor/Ewing's sarcoma (PNET/EWS) is primarily a tumor of soft tissues and bones. Primary localization of PNET/EWS in genitourinary organs is rare. No data on this localization of PNET/EWS are available in literature from Pakistan. We searched our adult uro-oncology records from 1994 till date and identified all cases of adult genitourinary and adrenal PNET/E...
PURPOSE The goal of this study was to identify second-generation mithramycin analogues that better target the EWS-FLI1 transcription factor for Ewing sarcoma. We previously established mithramycin as an EWS-FLI1 inhibitor, but the compound's toxicity prevented its use at effective concentrations in patients. EXPERIMENTAL DESIGN We screened a panel of mithralogs to establish their ability to i...
The EWS-ERG fusion protein is found in human sarcomas with the chromosomal translocation t(21;22)(q22;q12), where the translocation is considered to be an initiating event in sarcoma formation within uncommitted mesenchymal cells, probably long-lived progenitors capable of self renewal. The fusion protein may not therefore have an oncogenic capability beyond these progenitors. To assess whether...
The fusion between EWS and ETS family members is a key oncogenic event in Ewing tumors and important EWS-FLI1 target genes have been identified. However, until now, the search for EWS-FLI1 targets has been limited to promoter regions and no genome-wide comprehensive analysis of in vivo EWS-FLI1 binding sites has been undertaken. Using a ChIP-Seq approach to investigate EWS-FLI1-bound DNA sequen...
Fli-1, an ets related gene, was found to be rearranged in 75% of erythroleukemias induced by Friend murine leukemia virus. We have shown previously that the Fli-1 gene codes for a sequence specific transcriptional activator which contains two autonomous transcriptional activation domains, one at the amino terminal region and the other at the carboxy terminal region. Recently human Fli-1 gene wa...
ETS proteins are a family of transcription factors that play important roles in the development of cancer. The Ewing's sarcoma EWS/ETS fusion oncoproteins control a number of cancer-relevant phenotypes in that disease. We recently demonstrated that EWS/FLI, the most common EWS/ETS fusion in Ewing's sarcoma, regulates a portion of its target genes, including the critical target NR0B1, via GGAA-c...
UNLABELLED Metastatic Ewing sarcoma (EWS) is often resistant to current multimodal chemotherapeutic regimens. Oncolytic virus therapy (OV) is a novel therapeutic platform whereby viruses can selectively infect as well as replicate in and kill tumor cells, while sparing normal tissues. The purpose of this study is to investigate the efficacy of the biotherapeutic oncolytic agent, vesicular stoma...
