Table I. Percentage of transfected COS7 cells displaying various Golgi morphologies after etoposide treatment for 24 h.

Transfected construct	Tight and reticular	Loose and reticular	Dispersed and punctate
	%	%	%
Wild-type p115	18.4	42.9	38.7
TEKD757Ala p115	24.0	58.3	17.3

Results are the averages of duplicate samples from two separate experiments. In each case, 1,400 cells were counted by two independent observers. The expression levels of the wild-type and TEKD_757Ala p115 were identical, as determined by Western blot analysis (unpublished data).
