Interleukin-2 induction of T-cell G1 progression and c-myb expression
Abstract:
In studies to determine the biochemical mechanisms responsible for cell proliferation, synchronized T cells were used as a model for cellular growth control. By metabolic and morphologic criteria, it was found that activation of the T-cell antigen receptor rendered the cells responsive to interleukin-2 (IL-2), but did not move them through the cell cycle. Instead, IL-2 stimulated G1 progression to S phase, or lymphocyte "blastic transformation." During IL-2-promoted G1 progression, expression of the cellular proto-oncogene c-myb was induced transiently at six to seven times basal levels, maximal levels occurring at the midpoint of G1.
