(A–E) Prostate epithelial cell lines show different patterns of [3H]-label release into the medium on stimulation with 1 μ M 4α-phorbol [ ] or 1 μ M TPA [
] for up to 6 h as described in Materials and Methods. Results are means±s.d. (n=6). Repeat experiments (n=3) showed similar trends. For PNT2C2 and PNT1A lines **P<0.001, ***P<0.0001 against basal values. For P4E6, LNCaP and PC3 lines *P<0.05, **P<0.01, ***P<0.001 against basal values.
