[Expression and relationship of p27(kip1) and its related molecules Jab1 and CRM1 during proliferation of lymphoma cells U937].

Objective: To investigate the expression and relationship of p27(kip1) and its related molecules Jab1 and CRM1 during proliferation of lymphoma cells U937.

Methods: U937 cells were treated with serum starvation and release, and the effects of these treatments on the cell growth was tested with cell number counting. The expression and localization of p27(kip1), Jab1 and CRM1 in U937 cells were detected by Western blot, double immunolabelling and laser scanning confocal microscopy.
