Figure 4. The mechanism of TST action on AR gene splicing.
22RV1, VCaP and HEK293 cells were transiently transfected with mock vector or ARV7 minigene plasmid. 24 hours after transfection, cells were treated with TST-A at 0, 0.5, 2, 5 nM (A) or TST-D at 0, 5, 20, 50 nM (B) for 4 h respectively. Relative mRNA levels of AR-V7 mRNA levels to 18S rRNA were determined by real-time qPCR.
