Co-administration of αE2 or βE2 with DHT in LAPC-4 cells inhibits
DHT enhancement of TCM-induced MEC cell proliferation. In (A) MECs
were plated in 96-well plates and treated for 48 hr with TCMs collected from
LAPC-4 cells treated with a vehicle control, or αE2 (1 μM), or
βE2 (1 μM) in the presence or absence of DHT as indicated. In
(B) MECs were plated in 96-well plates and treated with vehicle
control, DHT (10 nM), αE2 (1 μM), or βE2 (1 μM)
alone or in combination for 48 hr. (C) is a representative RT-PCR
analysis of mouse ERα and ERβ expression in MECs. Mouse ovary
(mOvary) and tRNA were used as positive and negative control, respectively. The
data are the means ± SEM SEM of three independent triplicate experiments.
