| Research Abstract |
Using a CD7-expressing human acute myeloblasticleukaemia (AML) cell line, KG-1a, and its parentalline lacking CD7 expression, KG-1, we examined the CD7 gene structure and the levels in mRNA and protein expression, by cytogenetic observation, genomic PCR-direct sequencing, quantitative RT-PCR and flowcytometry. These analyses revealed that CD7 expression in KG-1a cells is 260-times higher than in KG -1 cells and is regulated at the mRNA level. To address further the regulatory mechanisms of CD7 expression, analyses on the transcription frequency or the mRNA stability are needed.
