Eosinophilia is common in myeloproliferative disorders (MPDs) with abnormalities of chromosome band 5q31-33, including those that present with t(1;5)(q23;q33). With the development of rational drug therapy, characterization of the molecular targets for these translocations could guide treatment and affect patient survival. We cloned the t(1;5)(q23;q33) and showed that it fuses platelet-derived ...

More than 35 different partner genes with the mixed lineage leukemia (MLL) gene have been cloned from leukemia cells with translocations involving chromosome 11 band q23. In this study, we report on a novel fusion partner of the MLL gene, AF4p12, which we have identified as the human homologue to the furry gene of Drosophila. AF4p12, highly conserved in evolution, encodes a large protein of 3,1...

More than 20 different partner genes with MLL have been cloned from leukemia cells with translocations involving chromosome 11 band q23 (11q23). All reported partner genes fused in-frame to MLL and the fusion cDNA encode chimeric MLL proteins with a significant portion derived from the partner genes. We analyzed one patient with de novo acute monoblastic leukemia with t(11;14)(q23;q24) and iden...

The t(11;19)(q23;p13.1) translocation is frequently found in adult myeloid leukemia. In the MLL/MEN fusion protein generated by this translocation, most of the coding region of the MEN protein, an RNA polymerase II elongation factor, is fused to the N-terminal third of the MLL protein, a possible transcriptional regulator. However, the molecular mechanism of leukemogenesis by the fusion protein...

The aim of this cross-sectional pilot survey was to assess patients’ perception and acceptance a tele(oral)medicine program during the COVID-19 pandemic. We conducted telephone on 84 patients MoMax ambulatory at Department Oral Sciences Maxillofacial Surgery “Sapienza” University Rome, Polyclinic Umberto I. Demographic characteristics were recorded, 24 question-survey completed. A Chi-square te...

MLL (ALL1, Htrx, HRX), which is located on chromosome band 11q23, frequently is rearranged in patients with therapy-related acute myeloid leukemia who previously were treated with DNA topoisomerase II inhibitors. In this study, we have identified a fusion partner of MLL in a 10-year-old female who developed therapy-related acute myeloid leukemia 17 months after treatment for Hodgkin's disease. ...
