ABSTRACT
Objective To investigate the effect of LMO2 gene,which is overexpressed in prostate peripheral zone than transitional zone,on proliferation and invasion of prostate cancer PC-3 cell line or normal prostate epithelial BPH-1 cell line.Methods Lentivirus overexpression system was used to establish the LMO2 protein overexpressed prostate WPMY-1 stromal cell line.The LMO2 mRNA and protein expression level of those cells was evaluated by qRT-PCR and western blot.The PC-3 or BPH-1 cells was cocultured with prostate stromal cells and the in vitro proliferation and invasion activity were detected by Cell Counting Kit-8 (CCK-8),EdU and Matrigel invasive assays.Results The stable LMO2 overexpressed prostate stromal cells WPMY-1-LMO2 was successfully established.The results of CCK-8,EdU experiments indicated the proliferation and invasion activity of PC-3 or BPH-1 cells were both enhanced through cocultured with WPMY-1-LMO2 cells.The proportion of EdU positive cells of PC-3 cultured in WPMY-1-LMO2 supernatant was (42.67 ± 6.03) %,and the difference was significant compared with the control group (29.33 ± 3.51) % (P < 0.05).The BPH-1 culturcd in the supernatant was (35.00 ± 2.52) %,aud the difference was significant compared with the control group (23.33 ± 2.52) % (P < 0.05).The number of invaded PC-3 or BPH-1 cells after co-cultured with WPMY-1-LMO2 cells was 38 ± 5 and 43 ± 3,respectively,which was significantly different compared with the control group (P < 0.05).Conclusions Tbe LMO2 overexpressed prostate stromal cells could induce proliferation and invasion of PC-3 or BPH-1 cells.The propensity of benign prostatic hyperplasia and prostate cancer at different zones may probably be related to distinctive gene expression between peripheral zone and transitional zone derived stromal cells.
