Acute lymphoblastic leukemia (ALL) in infants generally shows distinctive biologic features and has a poor prognosis. Cytogenetic studies indicate that many infant leukemias have chromosome 1 1 q23 translocations. Because of these findings and the distinct clinical features of infant leukemia, we investigated 30 cases of infant ALL for molecular defects of l l q23. Fourteen cases had cytogeneti...
Monoclonal antibody 7.1, which recognizes the chondroitin sulfate proteoglycan molecule NG2, was used to screen prospectively blast cells from 104 consecutive children at initial presentation with acute lymphoblastic leukemia (ALL). Reactivity with this antibody was found in 9 cases (8.6’701, of whom5hadat(4;11)(q21;q23)and4hadat(11;19)(p13;q23). None of the NG2cases had either translocation. S...
H R X Involvement in De Novo and Secondary Leukemias With Diverse Chromosome l l q 2 3 Abnormalities
Chromosome band 1 1 q23 is a site of recurrent translocations and interstitial deletions in human leukemias. Recent studies have shown that the 1 1 q23 gene HRX is fused to heterologous genes from chromosomes 4 or 19 after t(4;l l)(q21 ;q23) and t(ll;19)(q23; p l3 ) translocations to create fusion genes encoding proteins with structural features of chimeric transcription factors. In this report...
Pediatric mixed-lineage leukemia (MLL)-rearranged acute monoblastic leukemia with t(9;11)(p22;q23) has a favorable outcome compared with other MLL-rearranged AML. The biologic background for this difference remains unknown. Therefore, we compared gene expression profiles (GEPs; Affymetrix HGU133 + 2.0) of 26 t(9;11)(p22;q23) patients with 42 other MLL-rearranged AML patients to identify differe...
Translocations involving chromosome 11q23 frequently occur in pediatric acute myeloid leukemia (AML) and are associated with poor prognosis. In most cases, the MLL gene is involved, and more than 50 translocation partners have been described. Clinical outcome data of the 11q23-rearranged subgroups are scarce because most 11q23 series are too small for meaningful analysis of subgroups, although ...
Chromosome band 1 1 q23 is frequently involved in acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) de novo, as well as in myelodysplastic syndromes (MDS) and lymphoma. Five percent to 15% of patients treated with chemotherapy for a primary neoplasm develop therapy-related AML (t-AML) that may show rearrangements, usually translocations involving band 1 1 q23 or, less often, 2...
KiSS1 is a putative melanoma metastasis suppressor gene, the expression of which may be regulated by another gene(s) mapping to chromosome 6q16.3-q23. To additionally elucidate the role of KiSS1 in the progression of human melanoma in vivo, we examined KiSS1 mRNA expression in 51 melanocytic tumors with various stages of progression by in situ hybridization. We also examined a correlation betwe...
Translocations involving chromosome 11, band q23, are frequent recurring abnormalities in human acute lymphoblastic and acute myeloid leukemia. We used 19 biotin-labeled probes derived from genes and anonymous cosmids for hybridization to metaphase chromosomes from leukemia cells that contained four translocations involving band 11q23: t(4;11)(q21;q23), t(6;11)(q27;q23), t(9;11)(p22;q23), and t...
