This study assessed the mechanism of Bone Marrow Stromal Cells (BMSCs) in prostate cancer (PC) and its effect on MTA-1 gene and PC cell senescence. PC-3 cells were assigned into QL group (prostate cancer group: normal culture) and GS group (BMSCs group: treated with BMSCs) followed by analysis of MTA-1 level, cell senescence, apoptosis and invasion. MTA-1 level in QL group (0.83±0.07) was significantly higher than GS group (0.14±0.02) (P < 0.05), indicating that BMSCs had an inhibitory effect on MTA-1 expression. Similar change of MTA-l mRNA was also found with higher level in QL group than GS group (P < 0.05). Cell senescence was found in QS group but not QL group, indicating that BMSCs promote cell senescence. Compared with GS group, QL group has a higher cell number in G0/G1 (67.13±6.45%) and S (19.59±3.35%) than GS group (G0/G1:50.51±2.19% and S: 11.42±1.61%) but lower G2/M (QL: 15.97±3.59% versus GS: 32.25±3.24%). QL group had significantly lower cell apoptosis rate at 35 h (5.21±1.2%) and 45 h (3.97±0.95%) than GS group at 35 h (17.85±1.23%), 45 h (10.21±1.26%) with elevated number of invasions. In conclusion, BMSCs promote PC-3 cell senescence and apoptosis by inhibiting the expression of MTA-1 and reduce cell invasion ability.

Objection: Our research wanted to discuss miR-29b-3p in PCa occurrence and development and relative mechanisms. Methods: Collecting adjacent and cancer tissues from prostate cancer patients and measuring miR-29b-3p expressions by RT-qPCR and ISH assay. Using DU145 and PC3 cell lines which the miR-29b-3p were high expression in our study. Using miR inhibitor to knockdown miR-29b-3p in DU145 and PC3. Using CCK-8 and flow cytometry to measure cell proliferation and cell apoptosis, invasion cell number by transwell and wound healing rate by wound healing assay. The relative proteins expressions were measured using WB assay. p-AKT nuclear levels were evaluated using Cell immunofluorescence test. Using dual-luciferase reporter gene assay to analysis correlation miR-29b-3p and PTEN. Results: miR-29b-3p gene significantly increased. miR-29b-3p knockdown had effects to depress cell proliferation, increase cell apoptosis, depress invasion cells number and wound healing rates. PTEN proteins were significantly up-regulation and p-AKT and MMP-9 proteins expressions were significantly down-regulation (P < 0.001, respectively). And p-AKT nuclear volume were significantly depressed. And miR-29b-3p could target PTEN. Conclusion: miR-29b-3p played an oncology gene in prostate cancer via regulation PTEN/AKT pathway in vitro study.
