Frequent loss of heterozygosity at the TEL gene locus in acute lymphoblastic leukemia of childhood.
TEL is a new member of the ETS family of transcription factors which is rearranged in a number of hematologic malignancies with translocations involving chromosome band 12p13. In some cases, both TEL alleles are affected, resulting in loss of wild-type TEL function in the leukemic cells. In addition, 5% of children with acute lymphoblastic leukemia (ALL) have 12p12-p13 deletions, suggesting tha...
متن کاملLoss of heterozygosity in childhood de novo acute myelogenous leukemia.
A genome-wide screening for loss of heterozygosity (LOH), a marker for possible involvement of tumor suppressor genes, was conducted in 53 children with de novo acute myelogenous leukemia (AML). A total of 177 highly polymorphic microsatellite repeat markers were used in locus-specific polymerase chain reactions. This comprehensive allelotyping employed flow-sorted cells from diagnostic samples...
متن کاملFrequent Loss of Heterozygosity at the Retinoblastoma
Mice bearing retinoblastoma susceptibility gene (RB) germ-line muta tions almost invariably develop pituitary neoplasms. We therefore tested 17 patients with pituitary tumors for loss of heterozygosity (LOH) using an RB sequence polymorphism and 5 polymorphic microsatellite markers surrounding the RB gene on the long arm of chromosome 13. In all of the 13 malignant or highly invasive pituitary ...

15 صفحه اولSubmicroscopic deletions at 7q region are associated with recurrent chromosome abnormalities in acute leukemia.
BACKGROUND AND OBJECTIVES Loss of heterozygosity (LOH) on the long arm of chromosome 7 (7q) has been frequently reported in several types of human cancer including hematologic malignancies. Moreover, monosomy of chromosome 7 and 7q deletions have been associated in acute myeloid leukemia (AML) with aggressive disease and poor prognosis. DESIGN AND METHODS Using a panel of 11 polymorphic micro...
