Taken together, our studies revealed three unexpected findings which require further analysis: (1) expression of Id2 mRNA is often associated with lymphocytic transformation by HTLV-I or -II; (2) T-cells usually express either Id2 or Id3 mRNA , but B-cells often express both simultaneously; (3) non-dividing, normal PBL express high levels of Id2 and no Id3 mRNA ; and with the onset of cellular proliferation, levels of Id2 mRNA decrease while levels of Id3 mRNA increase, suggesting that regulation of expression of these closely related genes is disparate.
