pubmed-article:1695702 | pubmed:abstractText | Constitutive secretion of interleukin-6 (IL-6) has been proposed as a mechanism of transformation in multiple myeloma. We therefore studied 15 patients with this disease for rearrangements of the IL-6 and IL-6 receptor genes. Two patients with altered IL-6 genes were identified. Chromosome analysis revealed aberrations of chromosome 7, where the IL-6 gene resides, in only these two patients, but not in others without IL-6 rearrangements. In one of these patients, constitutive IL-6 m-RNA expression was observed. No alterations of IL-6 receptor genes were detected. | lld:pubmed |
