In vivo amplification of the PAX3-FKHR and PAX7-FKHR fusion genes in alveolar rhabdomyosarcoma.
In the pediatric cancer alveolar rhabdomyosarcoma, characteristic t(2;13)(q35;q14) or variant t(1;13)(p36;q14) chromosomal translocations generate PAX3-FKHR or PAX7-FKHR fusion genes. Using fluorescence in situ hybridization, reverse transcriptase-polymerase chain reaction and quantitative Southern blot analyses, we demonstrate that these fusion genes are amplified in 20% of fusion-positive tum...
متن کاملFusion of PAX7 to FKHR by the variant t(1;13)(p36;q14) translocation in alveolar rhabdomyosarcoma.
Although the t(2;13)(q35;q14) translocation has been found in most cases of the pediatric cancer alveolar rhabdomyosarcoma, several cases have been reported with a variant t(1;13)(p36;q14) translocation. Our findings indicate that this t(1;13) rearranges PAX7 on chromosome 1 and fuses it to FKHR on chromosome 13. This fusion results in a chimeric transcript consisting of 5' PAX7 and 3' FKHR reg...
متن کاملPax3:Fkhr interferes with embryonic Pax3 and Pax7 function: implications for alveolar rhabdomyosarcoma cell of origin.
To investigate the role of the translocation-associated gene Pax3:Fkhr in alveolar rhabdomyosarcomas, we generated a Cre-mediated conditional knock-in of Pax3:Fkhr into the mouse Pax3 locus. Exploring embryonic tumor cell origins, we replaced a Pax3 allele with Pax3:Fkhr throughout its expression domain, causing dominant-negative effects on Pax3 and paradoxical activation of the Pax3 target gen...
متن کاملPax7-FKHR transcriptional activity is enhanced by transcriptionally repressed MyoD.
Alveolar rhabdomyosarcoma (ARMS) are characterized by the expression of chimeric transcription factors Pax3-FKHR and Pax7-FKHR, due to chromosomal translocations fusing PAX3 or PAX7 with the FKHR gene. Although ARMS exhibits a muscle lineage phenotype, the cells evade terminal differentiation despite expressing the potent myogenic transcriptional regulator MyoD. Here we show that while Pax7-FKH...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
