Inhibition of Phospholipase D1 mRNA Expression Slows Down the Proliferation Rate of Prostate Cancer Cells That Have Transited to Androgen Independence.

Abstract:

:To explore the role of phospholipase D1 (PLD1) mRNA in transition of prostate cancer (PCa) cells to androgen independence, we used Arraystar Human LncRNA Microarray V3.0 to detect and compare the differential expression of PLD1 and its signaling pathway-related gene in standard androgen dependence prostate cancer (ADPC) cell line LNCaP before and after the occurrence of androgen independence prostate cancer (AIPC) transition. In addition, we used the shRNA lentiviral vector to inhibit the PLD1 mRNA expression and observed its effect on LNCaP cell proliferation after AIPC transition by using MTS method. The results showed that the expression level of PLD1 mRNA was increased by 373-fold after AIPC transition (P<0.05); the PI3K/AKT signaling pathway-related gene expression was also elevated (P<0.05); the growth rate of LNCaP cells that had transited to androgen independence was reduced by about 30% when the PLD1 mRNA expression was inhibited by the shRNA lentivirus as compared with the negative control group (P<0.05). All these results suggest that PLD1 mRNA and the related PI3K/AKT signaling pathway may play an important role in AIPC. Down-regulating the expression of PLD1 mRNA could to some extent inhibit the proliferation rate of PCa cells after AIPC transition.
