Identification and characterization of a novel Ets-2-related nuclear complex implicated in the activation of the human interleukin-12 p40 gene promot…
1997
Interleukin-12 (IL-12) is a proinflammatory cytokine produced by antigen-presenting cells in response to many microbial infections. IL-12 plays an important role in the generation of T helper type-1 cells, which favor cell-mediated immune response. IL-12 is composed of two different subunits, p40 and p35, whose expression can be regulated concomitantly or differentially. Monocytic cells, the major producers of IL-12, can be primed by interferon-gamma (IFN-gamma) to produce optimal amounts of IL-12 in response to LPS stimulation as a consequence of bacterial infection. The priming effect is exerted primarily at the transcriptional level on the p40 promoter in conjunction with the effects of …
Amplification of ETS2 oncogene in acute nonlymphoblastic leukemia with t(6;21;18).
1992
Cytogenetic and molecular studies in a case of acute nonlymphoblastic leukemia (ANLL) are reported in this paper. Bone marrow blasts carried a hypodiploid karyotype with a complex t(6;18;21)(6qter----6p21::21q22----21qter;18qter ----18p11::6p22----6pter; 21pter----21q22::6p21----6p22::18p11----18pte r) and other numerical and structural changes. We studied the organization and the expression of the ETS2 gene which is located on chromosome 21 in order to investigate its possible involvement in the disease. DNA analysis showed a 20-fold amplification of ETS2 sequences; an increase of 3- to 4-fold in the mRNAs level compared to normal was shown by Northern hybridization.
