Abstract：
:Thymic hormones have immunomodulatory effects on T cells and hence have been used clinically to restore the immunity of immunodeficient patients as well as to enhance the cellular immunity of cancer patients. Prothymosin alpha, which is a member of the thymic hormone family, has recently been suggested to act as a nuclear protein participating in the stimulation of cell proliferation. To characterize the biological activities ofprothymosin alpha in vitro, we established NIH3T3 cell transformants that constitutively express higher prothymosin alpha protein and its mRNA compared with the wild-type counterpart. Cells that overexpressed prothymosin alpha increased the proliferative activity assayed by the [3H]-thymidine incorporation or by the cell cycle analysis with the fluorescent-activated cell sorter. The results provide direct evidence that prothymosin alpha plays a role in cell proliferation by shortening the duration of the G1 phase.
