Table 1. Effect of PP on the invasive number of overexpressed and empty vector transformed hepatoma cells ($\overline{x}$±s), n = 3.

grouping	Number of cell invasion
Over ENO1+PP	147.000±14.422**, ##
Over ENO1	276.200±44.093
Empty Vector+PP	180.400±20.244##
Empty Vector	266.8±39.124
F	19.910
P	<0.001

Note

** indicates P< 0.01 compared with the overexpression ENO1 without PP group

^## means P< 0.01 Compared with empty vector group.
