The effect of thapsigargin on acrosomal exocytosis in the presence of N-[2-(p-Bromocinnamylamino) ethyl]-5isoquinolinesulfonamide (H89) or polyphosphoinositide -binding-peptide

Treatment	TG (AE cells [%])	Cont (AE cells [%])
Cont	40.0±5.00**	9.00±1.00
H89	47.0±2.65*	28.0±2.00*
PBP10	41.6±2.90*	23.3±2.30

The values AE cells (%) represent the mean±s.d. of duplicates from three experiments from three different donors. *P<0.05, significant difference compared to the corresponding control; **P<0.01, significant difference compared to the corresponding control. TG: thapsigargin; AE: acrosomal exocytosis; PBP10: polyphosphoinositide - binding-peptide; s.d.: standard deviation; Cont: Control
