- AB We established a novel T cell line, designated TK-6, from a patient with
- T cell lineage blast crisis of chronic myelogenous leukemia (CML)
- complicated by hypercalcemia. A surface marker study showed T cell
- phenotype, cluster designation (CD)4, CD5 and CD7. Light and electron
- microscopic examination revealed myeloperoxidase (MPO)-negative,
- however, ultrastructural examination under certain specific conditions
- demonstrated that some cells were MPO-positive. The TK-6 cell karyotype
- carried a t(9;22)(q34;q11) and additional chromosome aberrations,
- including a deletion of the long arm of chromosome 6 and the abnormality
- of chromosome 7. Southern blot analysis showed rearrangement of the T
- cell receptor beta-chain (TCR beta) gene and the major breakpoint
- cluster region (bcr) gene. Northern blot analysis detected the
- expression of the parathyroid hormone-related protein (PTHrP) gene,
- however, the proviral genome of human T cell leukemia virus type I
- (HTLV-I) was negative. This cell line will provide a valuable resource
- for the analysis of the relationship between T cell lineage crisis and
- myeloid differentiation and for the analysis of humoral hypercalcemia of
- malignancy (HHM) or leukemia.
