Although FRA16B was detected only in PBLs from two healthy subjects who had been previously treated for non-Hodgkin's lymphoma (NHL), both cell types displayed FRA16B in a patient with chronic myelomonocytic leukemia (CMMoL).
The presence of the Xmn I site 5' to the G gamma-globin gene (at-158 base pairs from the G gamma-globin gene cap site) was observed only in 1 typical JCML patient with elevated %G gamma.
The presence of the Xmn I site 5' to the G gamma-globin gene (at-158 base pairs from the G gamma-globin gene cap site) was observed only in 1 typical JCML patient with elevated %G gamma.
Karyotypes of different cellular populations made after separation of bone marrow cells on a gradient of Percoll were evaluated in seven patients affected by chronic myelomonocytic leukemia diagnosed according to FAB criteria.
A mutation within NRAS codon 12 could thus be demonstrated in a patient with idiopathic myelofibrosis and in another with chronic myelomonocytic leukemia.
In contrast to JCML, PB from six adults with Philadelphia (Ph1) chromosome-positive chronic myelogenous leukemia (Ph1 + CML) yielded CSA-dependent CFU-C colonies which were composed of granulocytes, macrophages, or both, as well as exuberant growth of BFU-E colonies.
We have investigated the effects of interleukin-4 (IL-4) on the proliferation of chronic myelomonocytic leukemia (CMMoL) cells in the chronic and leukemic transformation phases in vitro.
