ABF-1 is a human class ll basic helix-loop-helix transcription factor that is expressed predominately in EBV immortalized and activated B lymphocytes. A human cell line was stably transfected with a tetracycline regulated ABF-1 expression vector. The cell line revealed tight regulation of ABF-1 expression following stable incorporation of the vector into the genomic DNA. Upon induction of ABF-1 expression, the cell line exhibited a dramatic growth rate decrease. In order to monitor genes regulated by ABF-1, cells were collected both before and after induced ABF-1 expression and subjected to a microarray analysis. Early interpretations of the microarray data support the findings that ABF-1 may be regulating gene expression in a manner that facilitates withdrawal from the cell cycle.
